A proposed mission known as Uranus Orbiter and Probe would conduct a multiyear orbital tour to yield knowledge of ice giants in general and the Uranus system in particular.

The International Space Station will be steered to a controlled destruction in Earth's atmosphere in 2031, if all goes to plan. Should we be worried about the pollution this death dive will cause?

The Amateur Radio on the International Space Station (ARISS) aims to inspire and educate youth in STEM through connecting astronauts in orbit with people on the ground.

"At a time like this, we need to find more stories from the days when Americans outsmarted the bad guys and planted our flag on the moon."

"Analyzing and understanding the potential threats posed by UAP is an ongoing collaborative effort involving many departments and agencies."

Space specialists in China have begun to assess experiment samples brought back by the Shenzhou-18 crew that touched down November 4 in north China’s Inner Mongolia Autonomous Region.

China has moved up its timeline for bringing Mars samples to Earth, aiming to do so as early as 2028 — long before the U.S. is slated to achieve this same ambitious goal.

NASA remains in an ongoing test mode to determine what’s behind the ablative thermal protective material that chipped away unexpectedly from the Artemis 1 Orion heat shield during its reentry.

What is the amount of greenhouse warming required to heat up the cold climes of Mars enough so that trees can grow on the Red Planet?

The next few years are likely to be pivotal ones for NASA, according to a hard-hitting report by the U.S. National Academies of Sciences, Engineering and Medicine.

Satellite tracker and photographer Felix Schöfbänker has captured a variety of secret spacecraft on camera, revealing "things that either were not known, or only were speculated before."

Any lunar resource evaluation or prospecting campaign will need to be international in nature, as no one space agency will have the money or mandate to conduct it alone.

The Emirates Mission to the Asteroid Belt will conduct high-speed flybys of six asteroids, then orbit and drop a lander onto a seventh space rock.

As space agencies and private companies look toward sending human crews to Mars, they'll have to find ways to mitigate the dangers posed by high-energy radiation from solar storms.

If the future unfolds like some experts forecast, the moon is going to be one bustling spaceport. How can we handle all of that lunar traffic?
