Boeing Starliner's parachutes will be tested once more during an uncrewed test on Sept. 7. It was originally supposed to host astronauts, but NASA changed the plan mid-mission.

The experiment aboard China's Tiangong space station will expose bricks made of moon-soil simulant to space's harsh conditions, helping shape the future of lunar infrastructure.

NASA's Starliner astronauts will temporarily have an emergency spot available on a SpaceX Crew Dragon, but they can't wear spacesuits there. That will change in a few weeks.

Starliner's astronauts will spend at least 8 months in space, longer than a typical ISS crew. But numerous other astronauts have safely spent a year on the ISS, or even longer.

Chinese astronauts aboard the Tiangong space station are studying microbes, to help determine if some of Earth's early lifeforms can handle a simulated cosmic environment.

Boeing's Starliner spacecraft will fly back to Earth for a landing on Sept. 7, but without its crew. Its two astronauts will ride home on SpaceX Crew Dragon in February 2025.

A statue of Christa McAuliffe, NASA's "Teacher-in-Space" who died on board the space shuttle Challenger in 1986, has been unveiled in New Hampshire, the state where she taught.

The eerie sound was likened to a pulsing sonar-like ping.

U.S. Navy lieutenant and NASA astronaut Jonny Kim will board a Russian Soyuz spacecraft to fly to the ISS for an eight-month mission in 2025.

NASA's Crew-9 mission now has only 2 astronauts instead of 4. The last-minute change gives room to return 2 astronauts on the ISS who needed a new ride home.
