NASA’s two stuck astronauts took their first spacewalk together Thursday, exiting the International Space Station almost eight months after moving in. Commander Suni Williams and Butch Wilmore removed a broken antenna and wiped the station’s exterior for evidence of any microbes that might still be alive after launching

Despite the statement from President Trump, NASA had already scheduled the astronauts' return for late March or April.

Last year, 2024, was the warmest year on record for the planet, easily breaking the previous record set just a year earlier.

A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.

There are 20 amino acids that create the proteins required for life on our planet — and scientists have now found exactly 14 of them on an asteroid millions of miles away. The asteroid in question, named Bennu, was the focus of a very dreamy NASA mission called OSIRIS-REx that launched in 2016.

Studies of asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx spacecraft have revealed molecules that, on our planet, are key to life.

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that asteroids hold molecules believed to be the precursors to these chemicals. By studying the Bennu samples, they hope to gain more insight into how these ingredients could have evolved.

The founder of SpaceX said President Trump had asked his company to return two astronauts aboard the space station to Earth “as soon as possible.” NASA said it would do that “as soon as practical.”

Scientists from NASA and other institutions who have been analyzing the Bennu asteroid sample that returned to Earth last September found molecules, including amino acids, which are essential ingredients of life as we know it.

NASA is preparing the Orion spacecraft for its first crewed flight around the moon. Here's how astronauts will fly it.

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.
