Space Exploration

But as more and more satellites are launched into LEO...the region's getting a bit crowded.

NASA's ESCAPADE Mars probes embarked on a 'loiter' trajectory after launch, and scientists say that extra time in space could have some consequences for the twin spacecraft.

If nonliving materials can produce rich, organized mixtures of organic molecules, then the traditional signs we use to recognize biology may no longer be enough.

SpaceX launched the first mission of 2026 tonight (Jan. 2), sending an Italian Earth-observing satellite to orbit.

SpaceX will soon lower the orbits of about 4,400 Starlink satellites, to decrease the threat they pose to other spacecraft and reduce space traffic overall.

It's happening. We are going.

From astronauts looping around the moon to spacecraft reaching Mercury and asteroids near Earth, 2026 is shaping up to be a landmark year for space exploration.

"It's really not a question of robotic exploration or human exploration," Ehlmann said. "It is an 'and' — it's robotic and human exploration and how we do these best together."

An Artemis Orion capsule could take space shuttle Discovery's place in Houston, NASA's new chief says.

Tory Bruno, the longtime chief of the launch provider United Launch Alliance (ULA) has joined the competition at Blue Origin.
