More than 50 years since the end of NASA’s Apollo program, moon missions are about to start up again. As early as March, Artemis II is expected to take four astronauts to orbit the moon in preparation for a moon landing to come. In advance of next month’s launch, we spend an hour with former shuttle astronaut Winston Scott exploring spaceflight, moon missions and more.

Mankind has always wondered if we’re alone in the universe. Now, a Mars rover has found what looks like signs of life in the distant past on that planet. We’ll explore that possibility and learn more about what scientists are doing as they search for other signs in a conversation with astrophysicist Neil deGrasse Tyson.

In a post on social media late Saturday, Trump said he was withdrawing Isaacman's nomination after a "thorough review" of the tech billionaire's "prior associations."

Astronauts face several risks during spaceflight, including exposure to radiation.

A NASA spacecraft knocked into an asteroid two years ago to test planetary defense. Now, a new mission will inspect the damage, with the goal of helping future asteroid deflection.

Butch Wilmore and Suni Williams revealed what life has been like aboard the International Space Station after problems arose with their Starliner spacecraft, which returned home empty last week.

The space agency determined that the material was a metal alloy stanchion used on "NASA flight support equipment."
