International Space Station: Live updates

Soyuz undocks from the ISS

"Expedition 71 in is the history books!"

Soyuz MS-25 undocked from the International Space Station (ISS) at  4:37 am EDT (08:37 UTC) on Monday (Sept. 23). The undocking represents the beginning of a journey back to Earth for NASA astronaut  Tracy C. Dyson and Russian Cosmonauts Oleg Kononenko and Nikolai Chub. 

When the undocking command was given, the capsule was docked to the ISS Prichal module with the space station over Eastern Mongolia. The hooks needed just 90 seconds to secure Prichal and retract.

Soyuz MS-25 commander Kononenko and Chub have broken records for stays on the ISS, spending 374 days on the station. The prior record of 371 days was held by their fellow cosmonauts Sergei Prokopyev and Dmitry Petelin along with NASA's Frank Rubio, who occupuied the ISS from September 2022 to September 2023.

If the return of the Soyuz MS-25 goes according to plan NASA said it will touchdown will occur at around 8 a.m. EDT (1200 GMT), southeast of the Kazakh town of Dzhezkazgan.

New ISS crew launching today

A Russian Soyuz rocket will launch a new three-person crew to the International Space Station today to kick off the Expedition 72 mission to the orbiting lab. 

The Soyuz rocket will launch the Soyuz MS-26 spacecraft for Roscosmos to ferry NASA astronaut Don Pettit and Russian cosmonauts Alexey Ovchinin and Ivan Vagner to the space station from Baikonur Cosmodrome in Kazakhstan. Liftoff will be at 12:23 p.m. EDT (1623 GMT; 9:23 p.m. local Baikonur time). 

Pettit is renowned for his ability to squeeze amazing science out of his space missions. Check out our feature on this "space MacGyver" by Space.com's Elizabeth Howell ahead of his launch.

You can watch the Expedition 72 crew's Soyuz launch live online, courtesy of NASA TV, starting at 11:15 a.m. EDT (1515 GMT). A livestream video feed is available at the top of this page.

NASA will also broadcast the Soyuz's planned docking at the ISS, which is scheduled for 3:33 p.m. EDT (1933 GMT). That docking webcast will begin at 2:30 p.m. EDT (1830 GMT), with another livestream set for 5:30 p.m. EDT (2150 GMT) to cover a hatch opening ceremony at 5:50 p.m. EDT (2150 GMT).

Starliner remains at ISS port as SpaceX eyes Aug. 18 launch

Boeing's Starliner spacecraft, on its first historic mission with astronauts, will remain docked at the International Space Station as NASA and the company evaluate data from ground and in-space thruster testing, the agency stated on Thursday (Aug. 1)

"Teams are taking their time to analyze the results of recent docked hot-fire testing, finalize flight rationale for the spacecraft’s integrated propulsion system, and confirm system reliability ahead of Starliner's return to Earth," NASA officials wrote in a blog post.

Starliner's location at the forward port of the ISS Harmony module is supposed to be cleared to make way for SpaceX Crew-9, which is launching no earlier than Aug. 18. Starliner originally was expected to spend about 10 days in space after launching June 5, but remained for what has now been two months.

While the two NASA astronauts with Starliner are cleared to return anytime and are not stranded in space, they are staying at ISS to allow the root causes of helium leaks and thruster misfirings to be determined. Boeing wants to send the first operational mission to the ISS, which would last six months, in 2025 and may require changes to the design or how the propulsion system is used to achieve that.

NASA spacewalks to resume in fall

NASA plans to resume its spacewalks in the fall following a leak in the service and cooling umbilical area of a spacesuit and its attachment on June 24.

Astronaut Tracy Dyson experienced the coolant leak while in the hatch of the International Space Station (ISS), during the beginning minutes of a spacewalk. The hatch was open, but she had not left the facility yet. She and her spacewalking partner, Mike Barratt, were never in any danger.

NASA postponed future spacewalks pending an investigation, moving back future extravehicular activity (EVA) dates several times to allow time for the work to complete. The agency has now identified a fix and will replace the umbilical on her suit, agency officials said in a briefing today (July 26). 

"We're just working to find time in the busy [ISS] schedule to replan that series of EVAs," ISS program manager Dana Weigel said in the livestreamed briefing, referring to dockings and undockings of other spacecraft in the summer. "My expectation is that's that's out in the fall timeframe sometimes, so we're still working through that."

ISS operations unaffected by global tech outage

Operations on the International Space Station have not been affected by a global tech outage of Microsoft systems today (July 19), linked to a software bug with cybersecurity company Cloudstrike.

"NASA is assessing potential impacts to agency systems related to Microsoft partner CloudStrike," an agency representative wrote in an e-mail update today to Space.com. "So far, we have seen some impact to various Microsoft 365 apps and services. We are continuing to monitor the situation. Currently, there are no impacts to operations or communications for the International Space Station."

The Cloudstrike outage has created issues with air and train travel, as well as key services with banks and businesses around the world. The outage occurred early this morning in EDT hours, and resolution efforts by Microsoft and Cloudstrike are ongoing.

NASA plans independent review of Falcon 9 failure

NASA will perform its own re-authorization of SpaceX's Falcon 9 before the rocket launches its next astronaut crew or cargo mission, the agency confirmed Wednesday (July 17).

Falcon 9 experienced a rare failure during an engine burn of SpaceX rocket's second stage, due to an oxygen leak, during a launch on Thursday (July 11). A mandatory mishap investigation is ongoing. SpaceX, however, asked the Federal Aviation Administration Monday (July 15) to allow for future launches under a "public safety determination", meaning the launch posed no risk to public safety.

On SpaceX's near-term launch manifest is NASA's next International Space Station astronaut rotation. Called Crew-9, it is slated to send four astronauts to the ISS as early as mid-August. But NASA program manager Dana Weigel said the agency will have "its own process that's outside of what the FAA does" even if the administration rules in favor of SpaceX's request.

ISS will gently fall back to Earth before SpaceX vehicle pushes it into atmosphere

Though the International Space Station is meant to be replaced in the 2030s, it will take a long time for the orbiting lab to officially reach the end of its life, NASA says.

SpaceX's newly commissioned reentry vehicle will only push the International Space Station (ISS) into Earth's atmosphere some 12 to 18 months after the complex "drifts down" from its normal orbit. "We'll leave the crew on board as long as possible, so they're available to help maintain station and keep it healthy," NASA's Dana Weigel, ISS program manager, told reporters today (July 17) in a livestreamed briefing of the reentry plan.

"Our plan is for [the astronauts] to leave about six months before the final reentry, as ISS reaches about 220 kilometers [136 miles]," Weigel said, explaining that's as low as human vehicles are typically rated to fly. For comparison, the typical ISS orbit is 250 miles (400 km) above Earth.

NASA slates next spacewalk for July 29 after coolant leak

NASA will hold its next spacewalk no earlier than July 29 after a coolant leak halted the last excursion June 24.

Agency officials announced the date on the International Space Station blog from NASA, after saying in a teleconference on Friday (June 28) that they planned an extravehicular activity (EVA) at the end of July. A time of day is not yet available for the excursion.

"This change allows teams on the ground to continue to troubleshoot and understand the water leak in the service and cooling umbilical unit that forced an early end to a spacewalk on Monday, June 24," NASA officials wrote in the update.

Tracy Dyson and Mike Barratt, who were on the last EVA attempt that lasted just 31 minutes of its planned 6.5-hours, will make "hardware replacements and installations, preparations for future upgrades on science gear and photographic inspections of station pipelines" during the rescheduled spacewalk, NASA officials noted in a blog post June 27.

No landing date for Boeing Starliner, more tests required

NASA says Boeing Starliner will extend its first astronaut mission well into the summer, after launching June 5 for what was supposed to be a 10-day flight.

Starliner experienced both helium leaks and thruster issues during a June 6 docking with the International Space Station (ISS). The spacecraft is stable and rated to leave the ISS in case of emergency, Boeing and NASA leadership stress. But after testing the thrusters in space, NASA and Boeing said they want to take more time to understand the root cause.

A test campaign will start as soon as July 2 at the White Sands Test Facility in New Mexico to replicate how the thrusters were used during the flight, NASA commercial crew program manager Steve Stich said during a livestreamed update today (June 28) with reporters. The testing will take approximately two weeks, but that depends on what is found — and more analysis will be required afterwards. As such, NASA and Boeing do not yet have a landing date for Starliner.

"We're not going to target a specific date until we get that testing completed, and we look at the fault tree, and then we understand the path for it," Stich said.

NASA to update reporters on ISS issues at 2 p.m. EDT

NASA will provide an update on an unexpectedly busy week at ISS at 2 p.m. EDT (1800 GMT), along with discussion of Boeing Starliner's return plans. You can listen live here at Space.com, via NASA Television.

One astronaut had a spacesuit coolant leak during a spacewalk on June 24 that required halting the planned 6.5-hour excursion after only 31 minutes. (The crew was never in any major danger, NASA said at the time.) 

The Expedition 71 crew also temporarily took shelter in their return spacecraft June 26 after a satellite broke up in low Earth orbit, although the precautionary procedure lasted only an hour.

NASA spacewalk concludes after coolant leak, crew not in any danger

NASA astronauts Tracy Caldwell Dyson and Mike Barratt were told by Mission Control at 8:52 a.m. EDT (1252 GMT) to stop a planned 6.5-hour spacewalk outside the International Space Station (ISS). The pair had already switched over to the internal power in their suits at 8:46 a.m. (1246 GMT), meaning the spacewalk had technically started. Following the cancellation, astronauts opened the hatch into the ISS at 9:51 a.m. EDT (1351 GMT), officially ending the spacewalk. 

While being broadcast on a NASA Television livestream, they had reported "literally water everywhere" as they were moving their suits to internal power to prepare for the extravehicular activity. The leak appeared to be coming from a servicing and cooling umbilical (SCU) on Dyson's spacesuit, she reported. While the situation was serious, the astronauts were not in any danger due to the leak.

NASA reschedules spacewalk to June 24 after astronaut 'discomfort'

NASA has rescheduled an International Space Station spacewalk after a "spacesuit discomfort issue" that occurred, forcing a postponement while two astronauts donned suits for their planned excursion on Thursday (June 13).

The spacewalk will run no earlier than June 24, agency officials reported in a blog post late Friday (June 14). NASA's television schedule currently says that coverage will start on June 23 at a to be determined time, so it may be an early-morning spacewalk in EDT hours on June 24 unless the date has changed.

The spacewalk was postponed during the livestream on NASA Television June 13. "Spacewalkers Tracy Dyson and Matt Dominick were preparing for US EVA 90 — spacewalk 90 — today, but today's spacewalk will not be proceeding as planned," a NASA commentator said on the stream just after the postponement decision was made, adding, "we're standing by for more information, and we will share as we learn that."

Shortly after, a NASA update said the call was made due to a "spacesuit discomfort issue," but it did not indicate specify which astronaut or astronauts it had affected or what exactly had occurred.

The rescheduled Expedition 71 spacewalk will see astronauts "remove faulty radio hardware and swab station surfaces for microorganisms", NASA officials wrote. Then a second spacewalk is planned on July 2 for several maintenance tasks: removing and replacing a gyroscope assembly, relocating an antenna, and working on a dark matter experiment known as the Alpha Magnetic Spectrometer.

Spacewalk postponed due to 'discomfort issue'

According to a recent NASA blog post today's spacewalk outside the International Space Station "did not proceed as scheduled due to a spacesuit discomfort issue."

"NASA astronauts Tracy C. Dyson and Matt Dominick completed taking off their spacesuits about an hour before the crew was anticipated to exit the Quest airlock," NASA said.

NASA calls off spacewalk

NASA has postponed today's scheduled spacewalk with NASA astronauts Tracy C. Dyson and Matt Dominick.

The crew were already in their spacesuits and had been preparing to venture outside of the International Space Station at 8 a.m. EDT (1200 GMT). 

But according to a recent NASA statement, "The crew has just begun taking off their suits, at approximately 6:25 am CDT, about an hour before the crew was anticipated to exit the Quest airlock. We are standing by for more information and will share as we know it."

No emergency situation on space station, NASA says

"There is no emergency situation going on aboard the International Space Station," NASA officials confirmed late Wednesday after audio from an astronaut medical drill was accidentally broadcast live on NASA's ISS livestreams. You can read our full story on the medical drill audio on NASA's livestream for more details.

The strange audio issue occurred at 7:28 p.m. EDT (2328 GMT), when the voice of a flight surgeon speaking on a simulation audio channel aired live on NASA's official broadcasts. The eight-minute call, only one side of which was audible, was part of a simulation on Earth by NASA and its ISS partners. At no point was the space station crew in any danger.

"The International Space Station crew members were in their sleep period at the time," NASA officials said in the statement. "All remain healthy and safe, and tomorrow's spacewalk will start at 8 a.m. EDT as planned."

NASA astronauts prep for 1st of three upcoming EVAs

NASA astronauts Tracy Caldwell Dyson and Matthew Dominick are preparing to perform the first of three spacewalks scheduled for this summer. The clock will begin for the duo's 6.5-hour extravehicular activity (EVA) at 8 a.m. EDT (1200 GMT), Thursday, June 13. The EVA will focus on retrieving faulty equipment known as the radio frequency group, and swabbing the space station's exterior for samples of microorganisms for later testing.

Two cargo ships depart International Space Station

The International Space Station (ISS) saw two cargo ships depart for Earth only 15 hours apart.

A SpaceX cargo ship laden with science departed the space station Thursday (Dec. 21) and headed back toward Earth, following about a week of delays due to poor weather in the splashdown zone near Florida. SpaceX's robotic Dragon spacecraft undocked from the ISS at 5:05 p.m. EST (2205 GMT), as the two spacecraft were flying over the southwest coast of Chile. If all goes according to plan, Dragon will splash down late Friday morning (Dec. 22) off the coast of Tallahassee, Florida, NASA officials said. The splashdown will not be livestreamed.

Also, Northrop Grumman's uncrewed Cygnus NG-19 spacecraft left the International Space Station (ISS) at 8:06 a.m. EST (1306 GMT) on Friday, Dec. 22. The Canadarm2 robotic arm released the spacecraft over the north Atlantic ocean just one minute past the expected schedule, NASA official Rebecca Turkington said in a livestream on NASA Television. Cygnus will do a fire experiment for a couple of weeks before being commanded for a destructive re-entry in Earth's atmosphere in January 2024; the exact date of re-entry has not been released yet.

NASA shows what 2 tomatoes look like after being lost on International Space Station

We finally have imagery of NASA's lost space tomato — and surprise, there are two.

NASA released footage of two tiny tomatoes that were lost in 2022 after astronaut Frank Rubio harvested them on the International Space Station. The chance discovery in the six-bedroom complex showed us how the 17% humidity onboard affects food in a Ziploc bag; Rubio had temporarily stowed the food inside and found it floated away in the meantime.

ISS Russian Progress cargo ship successfully undocks: Report

The Russian Progress MS-23 cargo ship successfully departed from the International Space Station (ISS) early Wednesday (Nov. 29), according to Russian state media outlet TASS.

Progress was scheduled to leave its docking port at the Poisk module of the ISS at 2:55 a.m. EST (0755 GMT), according to a Tuesday (Nov. 28) blog post from NASA officials, and to enter Earth's atmosphere roughly 3.5 hours after departure. The spaceship had been docked at the orbiting complex since May 24.

With Progress MS-23 vacated from Poisk, that makes room for the next cargo ship to arrive. The Progress MS-25 ship is scheduled to launch with 5,600 pounds (2,540 kg) of cargo from the Baikonur Cosmodrome in Kazakhstan Friday (Dec. 1) at 4:25 a.m. EST (0925 GMT or 3:25 p.m. local time), and you can watch that event live here at Space.com, via NASA Television. Docking will happen at 6:14 a.m. EST (1114 GMT) on Sunday (Dec. 3) and will also be available live.

Canadian Space Agency astronaut will join Boeing Starliner crew to ISS in 2025

The Canadian Space Agency announced a new long-duration mission Tuesday (Nov. 22) for an astronaut on the International Space Station (ISS).

Joshua Kutryk, a test pilot with the Royal Canadian Air Force, will fly on the first operational Boeing Starliner mission in 2025 for a six-month mission to the ISS. Kutryk, on his first spaceflight, will join NASA veteran astronauts Scott Tingle (commander) and Mike Fincke (pilot). Another crew member will be assigned "following review and approval by the agency and its international partners."

Canada typically receives missions every six years based on its ISS contributions, and current spacecraft capacity. Kutryk wasn't the only Canadian with big news to share: fellow astronaut Jenni Gibbons was named backup to Jeremy Hansen, the CSA astronaut flying around the moon with Artemis 2 in 2024.

NASA ready for delayed Nov. 1 all-female spacewalk

NASA officials have once again postponed a rare all-woman spacewalk to Wednesday (Nov. 1) and the agency is ready to bring its astronauts outside, per recent updates. You can watch live here at Space.com, via NASA Television, starting at 6:30 a.m. EDT (1030 GMT).

The delay from Monday (Oct. 30) was "to allow the International Space Station crew and flight control team additional time to prepare for the excursion," officials wrote in an Oct. 26 update. Preparations are ongoing for the spacewalk as of Monday, NASA officials emphasized in a blog post that day.

NASA astronauts Jasmin Moghbeli and Loral O'Hara will do only the fourth extravehicular activity (EVA) with an all-woman crew, following a trio with Christina Koch and Jessica Meir of NASA in 2019 and 2020. 

The spacewalk was postponed from Oct. 20 following a leak on the ISS on the Russian side that remains under investigation following an Oct. 25 spacewalk by Roscosmos cosmonauts. A second NASA spacewalk, originally set for October as well, has also been postponed until later in the year.

ISS spacewalking astronauts find toxic 'blob' of coolant

Two cosmonauts conducting a spacewalk outside the International Space Station (ISS) on Wednesday (Oct. 25) got an up-close view of a coolant leak that was first observed flowing from an external radiator earlier this month.

Oleg Kononenko came so close to the growing "blob" or "droplet" — as the pooling ammonia was described — that one of his tethers became contaminated, necessitating it being bagged and left outside of the space station when the spacewalk ended.

Rare all-woman spacewalk remains on schedule after ISS leak

NASA has changed the spacewalk schedule following a leak on a Russian module of the International Space Station last week.

The agency has now dropped from two spacewalks in October to one, as a precaution. The spacewalk that is still going forward this month is a rare all-woman spacewalk scheduled for Oct. 30 following its own delay due to the leak, is still expected to go forward on that date. 

NASA astronauts Loral O'Hara and Jasmin Moghbeli will do the fourth-ever all-woman spacewalk, following a trio by NASA astronauts Christina Koch and Jessica Meir in 2019 and 2020. Moghbeli and O'Hara will remove a faulty electronics box and replace a bearing needed for one of the station's solar arrays.

A second spacewalk, originally set and then rescheduled for October, will now happen later in 2023 as NASA and Russia's federal space agency, Roscosmos, continue their analysis, NASA officials stated this week. The excursion will include O'Hara and European Space Agency astronaut Andreas Mogensen on other maintenance tasks.

The leak in Russia's Nauka science module started and stopped on Oct. 9, with an unknown cause. Roscosmos plans its own spacewalk on Oct. 25 to look at a suspect radiator up close, which was transferred from the Rassvet module earlier in 2023.

Crew-6 astronauts begin first full day in space

The astronauts of Crew-6 are undertaking their first day in space after launching on a SpaceX Falcon 9 early this morning (12:34 a.m. EST, 0634 GMT) towards the International Space Station.

Docking coverage will begin at 11:30 p.m. EST tonight (0430 GMT Saturday, March 3). Coverage is available here at Space.com, via NASA Television. Assuming the docking goes on time, these are the milestones to look for:

• 1:11 a.m. EST (0611 GMT): Docking with the ISS occurs. 
• 3:27 a.m. EST (0827 GMT): Hatch opening with the ISS occurs.
• 3:40 a.m. EST (0840 GMT): The welcome ceremony at the ISS begins.

SpaceX, NASA confirm Thursday (March 2) launch for Crew-6

A SpaceX Falcon 9 rocket will officially reattempt launch of the Crew-6 mission Thursday (March 2) at 12:34 a.m. EST (0534 GMT) and you can watch the event here at Space.com, courtesy of NASA Television. Weather conditions are 95% favorable for launch at NASA's Kennedy Space Center in coastal Florida.

"NASA's SpaceX Crew-6 mission is 'Go' for launch to the International Space Station following completion of a launch readiness review, weather briefing, and mission management meeting," agency officials wrote in a blog post Wednesday (March 1).

A launch attempt Monday (Feb. 27) to the International Space Station (ISS) had been called off 2.5 minutes before T-0 due to a ground-system issue, but NASA said the issue has been addressed.

SpaceX and NASA found a problem with ignition fluid, called triethylaluminum triethylboron or TEA-TEB, that sparks the oxidizer for the engines to turn on.

"During prelaunch, the TEA-TEB fluid⁠—which originates in a ground supply tank⁠— flows to the rocket's interface and back to a catch tank to remove gas from the ground plumbing," NASA officials wrote. "During engine start, the fluid then flows to the engines for ignition. Flow into the catch tank is one of several parameters used to determine that the fluid has been properly bled into the system."

A clogged ground filter reducing the flow to a TEA-TEB catch tank caused the issue and that filter has been replaced. The TEA-TEB nitrogen line was also purged with nitrogen and everything has been cleared for launch.

Following launch, Crew-6 and its four astronauts are scheduled to dock with the Harmony module at the ISS at 1:17 a.m. EST (0617 GMT) on Friday (March 3). Hatch opening is expected at 3:27 a.m. EST and the welcome ceremony at 3:40 a.m. EST. Space.com will also carry these events, courtesy of NASA.

SpaceX, NASA delay Crew-6 by one day

After a lengthy flight readiness review (FRR) on Tuesday (Feb. 21), NASA and SpaceX will delay the Crew-6 liftoff by 24 hours. 

Now a SpaceX Falcon 9 rocket will launch Crew-6's Dragon capsule Endeavour on Monday (Feb. 27) at 1:45 a.m. EST (0645 GMT). You can watch it live here at Space.com when the time comes.

Russian engineers study Soyuz coolant leak

NASA's live NASA TV coverage of the Soyuz spacecraft coolant leak on the International Space Station has ended, with NASA sharing updates via its website and social channels throughout the night. 

Meanwhile, Russian flight controllers at Roscosmos's Mission Control Center continue to study telemetry and data from the Soyuz MS-22 to understand the health of the spacecraft. 

"Experts in Moscow are going to be taking a look at their systems and responding to the leak according to their procedures and polices," NASA space station flight director Emily Nelson said during live NASA TV commentary. "Once they have a good understanding of the final status of the Soyuz tonight, we will then jointly make a decision about where to go forward from here."

NASA spokesperson Rob Navias said NASA will provide an update Thursday morning on the latest news from Roscosmos over the leak.

Inspection underway of leaky Soyuz spacecraft

Russian cosmonaut Anna Kikina is using the space station's European Robotic Arm to inspect the Soyuz MS-22 spacecraft as flight controllers on Earth study telemetry and other data from the spacecraft. 

Flight controllers with Russia's Roscosmos and NASA are weighing options on what to do about the Soyuz spacecraft, which serves as a return ship and lifeboat for three members of the station's 7-person crew.

Breaking: Soyuz spacecraft leaking coolant at space station

Russia's space agency Roscosmos has called off a spacewalk by two cosmonauts at the International Space Station today after an apparent coolant leak on a Soyuz MS-22 crew capsule spewed coolant around its docking port on the orbiting lab.

The leak was first detected at 7:45 p.m. EST (0045 Dec. 15 GMT) as cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to exit the space station for a 7-hour spacewalk outside the station. The Soyuz spacecraft launched to the space station on Sept. 21 to deliver the two cosmonauts and NASA astronaut Frank Rubio to the space station  and was due to return to Earth size months later. 

"The cause of this leak [is] not known at this time," NASA spokesperson Rob Navias said during live commentary. "Russian specialists are continuing to look at the data and discussing what may have triggered the leak."

This is a developing story and we'll share updates as they are available.

Teamwork and a '2001' cosplay

Expedition 67 commander Samantha Cristoforetti had a cosplay strategy in orbit. The Italian astronaut, despite having seen "about 15 movies", is a fan of the classic 1968 space opera film "2001: A Space Odyssey." 

A visit to a thrift store, and consultations with SpaceX and fellow space station residents,, helped on her long-standing quest to build up teamwork in orbit, while replicating an iconic scene from the film during which a flight attendant hangs upside down in a hatch.

"That is not something that I would buy for myself, normally," the European Space Agency astronaut told Space.com of her costume during a post-flight press conference with other SpaceX Crew-4 members on Thursday (Oct. 20). "But it seemed to fit perfectly for that need."

First European female commander helms International Space Station

Italian astronaut Samantha Cristoforetti took command of the International Space Station and Expedition 68 in a ceremony today (Sept. 28) livestreamed from orbit.

The expedition officially begins when previous ISS commander Oleg Artemyev and fellow cosmonauts Denis Matveev and Sergei Korsakov depart the orbiting lab early Thursday (Sept. 29) aboard a Russian Soyuz spacecraft.

Cristoforetti is the fifth European commander of the ISS, following Frank De Winne, Alexander Gerst, Luca Parmitano and Thomas Pesquet, according to the European Space Agency (ESA).

Artemyev struck notes of peace during the changeover ceremony, closing an expedition that had taken place in its entirety during the ongoing Russian invasion of Ukraine that started in February. "War will end everywhere," he said at one point.

"In spite of everything, in spite of all the storms on Earth, we continue our international cooperation, and thank God that there are smart people who do not stop such a thread of peace," Artemyev added in Russian. (This translation was provided by Google from an automated transcript of his speech.)

International Space Station spacewalk concludes

NASA is concluding coverage of an International Space Station (ISS) spacewalk that saw a robotic arm and a big boom being manipulated in orbit.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev easily finished and exceeded their assigned spacewalk tasks during a 7 hour, x minute that began at 9:25 a.m. EDT (1325 GMT).

The duo blazed through the remaining tasks left over from an Aug. 17 spacewalk cut short due to a power issue in a spacesuit; the spacesuits, incidentally, worked perfectly this time during the 7 hour, 47 minute spacewalk.

"You completed more than you set out to do! Very productive," a representative from Moscow Mission Control told the cosmonauts just after they closed the hatch. (The transmission was in Russian; interpretation was available in English on NASA Television.)

The cosmonauts concluded several configuration tasks for the European Robotic Arm and in one of several get-ahead activities, extended the Strela crane boom between the Poisk and FGB modules on the Russian side of the ISS.

Watch two cosmonauts spacewalking live before they go inside

Two Russian cosmonauts are wrapping up their tasks outside the International Space Station, but you still have time to watch them live. NASA Television is broadcasting the spacewalk, which started this morning at 9:25 a.m. EDT (1325 GMT). 

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev are far ahead of schedule and working on get-ahead tasks after configuring the European Robotic Arm. They are now seven hours into what was scheduled to be a 6.5-hour spacewalk.

Russian cosmonauts extend boom on International Space Station

At nearly 6.5 hours into today's spacewalk, the Russian cosmonauts continue to perform get-ahead tasks outside the International Space Station. They are currently working at extending a boom between the Poisk and core FGB modules on the Russian side of the complex.

Both cosmonauts reported they were feeling great when asked by Russian mission control in Moscow, during a short break before orbital sunrise. (The ISS circles Earth about every 90 minutes.) Their spacewalk was nominally expected to be 6.5 hours; the energetic duo is far ahead of their timeline and continuing their excursion.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev exited the Poisk airlock at 9:25 a.m. EDT (1325 GMT) to work on the European Robotic Arm. Coverage is ongoing on NASA Television.

Spacewalking cosmonauts pivot to 'get-ahead' tasks

More than five hours into today's International Space Station spacewalk, two cosmonauts are so far ahead of schedule that they are working on "get-ahead tasks," NASA officials said in an update minutes ago on NASA Television. Coverage is ongoing.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev exited the Poisk airlock at 9:25 a.m. EDT (1325 GMT) to configure a European Robotic Arm and have already executed what they were asked to do for the 6.5-hour spacewalk.

They installed a work platform on the Russian Nauka module, configured a control panel, adjusted the arm's "end effector" for grasping payloads, and tied down launch restraints and insulation they removed earlier in the spacewalk.

Cosmonauts more than an hour ahead of schedule

At more than four hours into today's International Space Station spacewalk, the cosmonauts are at least 1 hour and 10 minutes ahead of schedule.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev exited the Poisk airlock at 9:25 a.m. EDT (1325 GMT) and made their way over to the European Robotic Arm, which they are currently configuring for in-orbit use.

So far the cosmonauts have removed and bundled some extra insulation, worked with a control panel and done other configuration activities to get the robotic arm ready for service.

The spacewalk is scheduled for 6.5 hours.

Roscosmos spacewalkers 50 minutes ahead of schedule

Two Russian cosmonauts working at the International Space Station are 50 minutes ahead of the timeline on their 6.5-hour scheduled spacewalk.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev, who exited the Russian Poisk module at 9:25 a.m. EDT (1325 GMT), are approximately three hours into their effort to configure the European Robotic Arm.

They have removed an external control panel on the arm and are now working on removing and bundling insulation, NASA officials said in an update.

Coverage continues live on NASA Television.

Russian cosmonauts see forest fires from space

Two Russian cosmonauts commented on the powerful forest fires raging in the western United States from their vantage point during a spacewalk at the International Space Station.

"You can see those forest fires. That is impressive," one of the spacewalkers commented shortly before 11:20 a.m. EDT (1520 GMT), as the extra vehicular activity approaches its second hour. (He was speaking in Russian; the English interpretation came through NASA.)

They were referring to powerful forest fires raging in California amid heat warnings that are forcing evacuations nearby Los Angeles.

Expedition 67 commander Oleg Artemyev and flight engineer Denis Matveev are finishing up tasks they could not complete in August after a spacewalk was cut short due to a spacesuit power issue.

The duo are configuring the European Robotic Arm ahead of operations. They have removed a protective cover and are now working on a control panel to get the arm set up after its first ground control test a few days ago.

Former NASA chief expresses concern about ISS transition

A former Trump-era NASA administrator says Congress needs to do more to have commercial space stations ready in time.

During a livestream on Sunday, former chief Jim Bridenstine, who led NASA between April 2018 and January 2021, said Congress is moving too slowly on approving replacements to the International Space Station (ISS), especially given Russia is now saying it will pull out after 2024 to focus on building a Russian-owned space station.

He expressed worry that NASA-funded commercial stations will not be ready in time to fill gaps in low Earth orbit research. (The agency is banking on the ISS partnership being extended to 2030, from 2024, to allow time for those replacements to get up and running.)

"Congress, quite frankly, is at fault for any gap we have on low Earth orbit, because they have been negligent in a replacement for the International Space Station," Bridenstine said. "We've known forever that it [the ISS] is not going to last forever, but we haven't been doing what's necessary to prevent the gap from happening. Now that gap seems to be accelerating, and nobody is talking about it."

Both cosmonauts inside airlock, spacewalk ends

Cosmonauts Denis Matveev and Oleg Artemyev are now both inside the Poisk airlok and have closed the outer hatch as they work to end today's spacewalk.  

The hatch was closed at 1:54p.m. EDT (1754 GMT) to officially end today's spacewalk early. 

Total elapsed spacewalk time: 4 hours, 1 minute of 6 planned hours. 

Spacewalk aborted over spacesuit power problem

Russian flight controllers have called off today's spacewalk outside the International Space Station due to the spacesuit power problem on Oleg Artemev's Orlan spacesuit. Read our initial story.

"Today's spacewalk by Oleg Artemyev and Denis Matveev is being ended earlier than planned," NASA spokesperson Rob Navias said. 

Watch the Russian spacewalk live now.

The spacewalk, which began around 9:20 a.m. EDT today, was expected to run about six hours. But about three hours in, Artemyev experienced a spacesuit voltage drop as he and Matveev worked on the station's new European Robotic Arm. Flight controllers immediately ordered Artemyev back inside the station's Poisk airlock to plug his suit into the station's power system.  

While Artemyev is inside the Poisk airlock, Matveev has been outside performing clean up tasks. He will not complete the robotic arm prep work due to it being cut short. Flight controllers cautioned Matveev not to rush. 

"Take your time, do not be in a hurry," they said.

Cosmonaut feels good despite spacesuit issue

Russian cosmonaut Oleg Artemyev says he is in good spirits despite a power issue with his Orlan spacesuit. The issue occurred about an hour ago outside the International Space Station as Artemyev and crewmate Denis Matveev worked on the station's new European Robotic Arm. 

Flight controllers asked Artemyev how he felt. 

"I'm energized, I've had a good nap," Artemyev said. "I've had a good rest."

He added that he definitely felt better than at the start of the airlock.

Russian flight controllers weigh spacewalk options

Russian flight controllers are placing the space station's European Robotic Arm into a safe configuration as they discuss whether to continue with today's spacewalk by cosmonauts Oleg Artemyev and Denis Matveev. 

Watch the Russian spacewalk live now.

Artemyev remains inside the Russian-built Poisk airlock with his Orlan spacesuit plugged directly into the station's power grid while Matveev waits outside. Today's spacewalk begin at about 9:20 a.m. EDT (1320 GMT) and was expected to last about 6 hours. The spacesuit issue cropped up at about the midpoint of the spacewalk around 12 p.m. EDT.

Cosmonaut suffers spacesuit issue on spacewalk

Russian cosmonaut Oleg Artemyev has been ordered back inside the  Poisk airlock after his Orlan spacesuit experienced an unexpected voltage fluctuation during today's spacewalk, NASA reports. 

Russia's Mission Control ordered Artemyeve to the station's airlock, where he plugged his suit into the station's power supply. His spacewalking partner Denis Matveev is waiting outside the airlock as Russian flight controllers discuss the next steps for today's spacewalk.

"Artemyev is in the airlock, never was in any danger," NASA spokesperson Rob Navias said. 

The issue occurred at about 12 p.m. EDT (1600 GMT), Navias said. 

First camera installed, working on second camera installation

As we approach the two-hour mark of today's International Space Station spacewalk, the two Russian cosmonauts have set up the first elbow camera and removed thermal insulation and a launch restraint from the European Robotic Arm, according to NASA.

They are now waiting for the arm to be maneuvered into the correct configuration to allow for installation of a second elbow camera. The cameras will be useful to allow for correct depth perception of the arm, which is needed to maneuver objects safely in the harsh lighting conditions of space.

Expedition 67 commander Oleg Artemyev, in red stripes, is on his seventh spacewalk and flight engineer Denis Matveev, in blue, is on his third spacewalk. The spacewalkers are expected to spend about 6.5 hours working outside in their Orlan spacesuits. Live coverage continues.

Cosmonauts prepare for camera installation

At the one-hour mark foe spacewalk, the cosmonauts are moving towards the European Robotic Arm in preparation for their first step. Their first major task will be installing one of two "elbow light" cameras to assist the arm with depth perception. Depth perception is crucial in space to allow for accurate grasping and manipulation of objects. The spacewalk is set to last 6.5 hours.

Spacewalk officially begins

The hatch to the Poisk airlock is open, marking the official start to the expected 6.5-hour long spacewalk today. 

Expedition 67 commander Oleg Artemyev (in red stripes) and flight engineer Denis Matveev (n blue stripes) officially began their spacewalk at 9:53 a.m. EDT (1353 GMT), according to NASA, putting them about 33 minutes behind when they were expected to start the spacewalk.

Their goal is to continue preparing the European Robotic Arm for operations.

NASA and private companies expect commercial space station demand

NASA, along with companies working on new low Earth orbit space stations, are optimistic these complexes will meet the needs of the International Space Station post-retirement.

These complexes will be necessary due to the amount of research being generated by the International Space Station, panelists said at a July 26 discussion at NASA's 11th annual International Space Station Research and Development Conference (ISSRDC).

"A platform to be able to continue to do the science and other research that we're doing on ISS will absolutely be needed for exploration," said NASA's Angela Hart, program manager for the agency's Commercial LEO Development Program Office, at the Johnson Space Center (JSC) in Houston.

SpaceX rocket for Crew 5 being repaired after damage

Both SpaceX and the passengers of Crew-5 say they are confident NASA's rigorous safety requirements will be met following an incident that damaged the Falcon 9 rocket now scheduled to carry people into space in September.

The first stage of the booster sustained slight damage after colliding with a bridge during transport, delaying the launch as SpaceX addresses the underlying issues, the company said during a Crew-5 news conference Thursday (Aug. 5). (NASA disclosed the damage before, but not the cause.)

SpaceX is working through analysis "to assure that that stage would be ready to go, and absolutely safe to fly the crew as we do for every mission," said Benjamin Reed, SpaceX's senior director of the human spaceflight program.

NASA astronaut Nicole Mann, commander of Crew-5, said SpaceX has been in regular contact with her crew. "We have full confidence that NASA and SpaceX and the international partners are not going to put us on a rocket or a spacecraft that they feel is not ready to go," she added in the same briefing.

NASA requests former astronauts chaperone private missions

NASA is asking that all private astronaut missions to the International Space Station (ISS) have an experienced former agency astronaut commanding the group. A new solicitation notice by NASA, not finalized, includes this request among other changes for private astronaut missions.

The new rule comes from lessons learned based on Axiom Space's first mission to the ISS earlier this year. The crew required help from professional astronauts of Expedition 67 to complete some of their experiments. (The solicitation was first noticed by SpaceNews).

Russia says it will leave the International Space Station after 2024

Russia will leave the International Space Station (ISS) program after 2024, according to an update from the new chief of Russia's federal space agency Roscosmos Tuesday (July 26).

The announcement, which sounds more definitive than past statements, comes after Roscosmos leadership threatened to leave the International Space Station partnership for months. "The decision to leave the station after 2024 has been made," the current head of Roscosmos, Yuri Borisov, said, according to the Associated Press.

Speaking from space through video chat at the 11th annual International Space Station Research and Development Conference, NASA astronaut Kjell Lindgren briefly addressed the matter. "That is very recent news, and so we haven't heard anything officially," he said. "Of course ... we were trained to do a mission up here, and that mission is one that requires the whole crew, and so we continue to work every day to conduct the science and research that we've been trained to conduct."

Spacewalk concludes

The European Space Agency's Samantha Cristoforetti concluded her historic first spacewalk for a European woman alongside experienced spacewalker Oleg Artemyev. 

The official end to the Russian-segment spacewalk was at 5:55 p.m. EDT (2155 GMT) and the duo spent 7 hours, 5 minutes working outside the International Space Station, according to NASA Television. The work had been forecasted to last seven hours.

Russian mission control elected to move one of the major tasks to another day, citing limited resources in the Orlan spacesuits to accomplish the work. (The spacesuited crew were delayed by roughly 50 minutes during routine equipment checkouts prior to opening the hatch at 10:50 a.m. EDT or 1450 GMT.)

The spacewalkers and the rest of the Expedition 67 crew were also advised today that there will be no need to perform an orbital debris avoidance maneuver after the spacewalk concludes. The possibility had been brought up during the spacewalk when a piece of unidentified debris strayed a little close to the orbit of ISS. No one was ever in any danger, NASA emphasized during the broadcast.

Watch Space.com for our wrap-up story covering the spacewalk.

ISS controllers tracking space debris, no action at this time

Controllers for the International Space Station are monitoring a piece of space debris that may come into conjunction, or come nearby, the orbiting complex "well after" the spacewalk is concluded, a NASA spokesperson said in a live update.

Following a live discussion between Expedition 67 astronauts and Mission Control in Houston, spokesperson Rob Navias told NASA TV viewers at 3:18 p.m. EDT (0718 GMT) that the crew is in no danger and that no immediate action is required.

"At the moment there is no concern or no action that will be required unless future tracking updates dictate otherwise. We'll keep you posted," Navias said during the spacewalk broadcast. Spacewalkers Samantha Cristoforetti (European Space Agency) and Oleg Artemyev (Roscosmos) are roughly 4.5 hours through their extravehicular activities that began at 10:50 EDT (14:50 GMT).

The space station is capable of avoiding the space debris, should that be required, Navias emphasized. No further details were provided by Navias about the time of the expected conjunction, how far away the debris is, the size of the object, or what object is being tracked.

Soyuz crew in good health after landing

The U.S.-Russian crew of the Soyuz MS-19 spacecraft is in good health and spirits after their smooth landing on the steppes of Kazakhstan. Read our full landing story.

Roscosmos TV cameras showed NASA astronaut Mark Vande Hei and cosmonauts Pyotr Dubrov and Anton Shkaplerov with wide smiles on their faces as they were helped out of their Soyuz capsule. Each of the space travelers were hoisted out of the Soyuz, which had rolled over after landing due to winds, and placed in reclined couches as they readapt to life on Earth. 

They waved to cameras during a photo session and were then carried into a nearby medical tent for medical checks and to doff their Russian Sokol spacesuits and climb into more comfortable flight suits. 

Once those medical checks are complete, each of the Soyuz crewmembers will head to a rally point airport in Kazakhstan. A NASA jet is awaiting Vande Hei to take him back to Houston while a Roscosmos plane will ferry Shkaplerov and Dubrov home to Russia's Star City training site near Moscow. 

That's a wrap for our landing coverage of Soyuz MS-19. 

The next mission to the ISS will be the private Ax-1 mission launching on a SpaceX rocket on April 6. We'll have live coverage of that here and on our Ax-1 mission updates page during the 11-day trip. 

NASA and SpaceX will then launch the Crew-4 mission to the ISS on April 19.

TOUCHDOWN! Soyuz lands with crew of 3

Touchdown confirmed! The Soyuz MS-19 spacecraft carrying NASA astronaut Mark Vande Hei and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov has landed safely on the remote steppes of Kazakhstan at 7:28 a.m. EDT (1128 GMT). 

Russian recovery crews are closing in on the landing site in helicopters and ground vehicles. NASA and Roscosmos personnel will soon extract the crew and prepare the space travelers for their trip home. 

First, Russian recovery teams will set up an inflatable medical tent to prepare to receive the Soyuz crew while others safeguard the vehicle so the crew can be extracted. 

Once the crew is extracted from the Soyuz, they will have a short photo session outside the capsule before heading off to medical tents, and then to an airport in for their trip home. Vande Hei will be headed back to Houston while Dubrov and Shkaplerov will head home to Moscow. -- Tariq Malik

The Soyuz MS-19 spacecraft carrying a crew of three has deployed its main parachute and is safely descending back to Earth. 

Everything has gone as planned for the landing. NASA astronaut Mark Vande Hei and his two Russian crewmates are doing well as they return to Earth.

Soyuz spacecraft module separation

The Soyuz spacecraft carrying NASA astronaut Mark Vande Hei and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov has jettisoned its orbital and propulsion modules as its crew capsule plunges through Earth's atmosphere for today's landing. 

The crew capsule is a gumdrop-shaped module that forms the central core of the Soyuz spacecraft. Its orbital and propulsion modules are disposable and no longer needed during reentry. 

The crew capsule will deploy a main parachute to slow its descent to the Earth's surface in Kazakhstan. It will fire retrorockets just before touchdown to further cushion its landing. 

Landing remains on schedule for 7:28 am ET (1128 GMT).

Deorbit burn: Soyuz returning to Earth

The deorbit burn has begun for today's Soyuz MS-19 spacecraft landing to return astronaut Mark Vande Hei and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov home from the International Space Station. 

The deorbit burn is a short 4-minute, 59-second maneuver to slow the Soyuz so that it can leave orbit and descend back to Earth for a landing on the steppes of Kazakhstan. You can see a profile of the landing approach above. 

Below is the target landing area and approach in Kazakhstan for today's landing.

Soyuz MS-19 crew prepares for landing

With today's undocking from the International Space Station complete, the Soyuz MS-19 crew is now preparing for the return to Earth in three hours. NASA's live webcast coverage of the landing has resumed ahead of the planned deorbit burn at 6:34 a.m. EDT (1034 GMT). You can watch the Soyuz landing live on Space.com. We have feeds on our homepage and our preview for today's landing.

The deorbit burn will place the Soyuz MS-19 on a descending track for its planned 7:38 a.m. EDT (1138 GMT) landing on the steps of Kazakhstan. 

While we wait for the deorbit burn. Check out some amazing views of the Soyuz's undocking earlier today.

So

Russian cosmonaut Pyotr Dubrov is continuing his photo and video session of the International Space Station as fellow cosmonaut Anton Shkaplerov flies the Soyuz MS-19 spacecraft around the station after today's undocking.

"That's beautiful, we are flying over some continents and it all looks beautiful but the Russian segment is all in shadow," one of the cosmonauts said. 

"Wow!" a cosmonaut added. "Every time you see it, it's almost like a surprise."

The Soyuz and space station were passing over western China when this view was captured from the Soyuz's onboard camera.

Recovery crew is on site

The crew is reportedly safe and in good health as search and recovery teams are helping them out of the capsule. 

The Soyuz landed upright and did not tip over after the impact, which could help speed up the recovery process. 

Roscosmos confirms Soyuz landing

The Soyuz MS-20 has successfully touched down, Dmitry Rogozin, director general of Russia's space agency Roscosmos, announced on Twitter. 

NASA TV commentator Brandi Dean said that bad weather in Kazakhstan has somewhat hindered the recovery effort, but there is "no reason to suspect that anything is wrong." 

Recovery teams "had visuals of the Soyuz descending under parachutes, but because of the visibility issues with the weather there at the landing site [they] did not see the actual touchdown," Dean said. "So they're working on getting to the Soyuz at this point and we are standing by for confirmation that they are there with the crew."

Touchdown?

The Soyuz MS-20 spacecraft should have touched down on time at 10:13 p.m. EST (0313 GMT), but NASA and Roscosmos have not yet confirmed the landing, and we're still waiting on the first video footage from the landing site. There are no indications that anything went wrong with the landing, according to NASA TV commentator Brandi Dean.

Megan McArthur shares stunning Earth timelapse

Lightning storms, auroras and city lights glow across planet Earth in this gorgeous new timelapse video captured by NASA astronaut Megan McArther at the International Space Station. 

"Friday Night Lightning!" McArthur tweeted. "Checkout this time lapse taken over Africa from our cupola. In addition to thunderstorms, you can see city lights, the Milky Way, satellites, and even a bit of aurora at the end." 

Russian film crew boards space station

Russian actress Yulia Peresild and producer-director Klim Shipenko have entered the International Space Station with their cosmonaut guide Anton Shkaplerov to begin their 12-day movie shoot in orbit.

The trio entered the station's Rassvet module at about 11 a.m. EDT (1500 GMT), jus about 6 hours after launching into orbit on their Soyuz rocket. They joined seven other crewmembers already aboard the station, including Expedition 65 cosmonaut Oleg Novitskiy, who will appear in the film Peresild and Shipenko are shooting. It's called "The Challenge," with Peresild portraying a surgeon sent into orbit to help a cosmonaut (Novitskiy) in medical distress. 

"I still feel that it's all a dream and I'm still asleep," Peresild, 37, told Russia's Channel One during a welcome ceremony on the station. 

Shipenko agreed. 

"Yes, it's almost impossible to think that this all came to reality," the 38-year-old director said.

During the welcome ceremony, Peresild received a congratulatory call from Valentina Tereshkova, who became the first woman in space in 1963 on the Vostok 6 mission. 

"It was extremely emotional for everyone, from sadness to happiness," Tereshkova said of the launch in Russian, which was translated on NASA TV. "We're very proud of you," she added, saying she had only one wish for the crew.

"Everything should go nominal, that's our best wish," Tereshkova said. "We want all your dreams to come true and we'll be waiting for you back here on Earth."

Hatch Opening Underway

Astronauts on the International Space Station are now working to open the hatches between the station and the Soyuz MS-19 spacecraft, allowing the Russian film crew to enter the orbiting lab.

The Soyuz MS-19 spacecraft carrying a Russian actress and her producer/director has successfully docked at the International Space Station. It linked up with a port on the station's Rassvet module at 8:22 a.m. EDT (1222 GMT), about 10 minutes later than planned after communications issues forced cosmonaut Anton Shklaperov to take manual control of the Soyuz for the docking. 

Despite the communications issue, Shklaperov docked the Soyuz at its port to deliver Russian actress Yulia Peresild and producer-director Klim Shipenko to the station. The duo will film scenes for an upcoming space film called "The Challenge," with Peresild portraying a surgeon launched into space to help an ailing cosmonaut, to be portrayed by cosmonaut Oleg Novitskiy, who is already aboard the space station.

"So the Soyuz MS-19's safely at port, and a Russian actress and her producer-director are on set at the International Space Station for 12 days of movie making," NASA spokesperson Rob Navias said during live commentary.

Peresild, Shipenko and Shklaperov will enter the space station at 10:05 a.m. EDT (1405 GMT) when the hatches are due to open between the Soyuz and station. NASA's live coverage will resume at 9:30 a.m. EDT (1330 GMT).
