NASA astronauts Jessica Meir and Christina Koch conducted the first all-female spacewalk outside of the International Space Station. The spacewalk officially began at 7:38 a.m. ET and lasted for seven hours and 17 minutes, ending at 2:55 p.m. ET. The spacewalk went well, according to both astronauts, and they were even able to accomplish some get-ahead tasks on the station. This was the fourth spacewalk for Koch and the first for Meir. Based on their position on the platform, the astronauts were able to see the Earth pass beneath their feet.

By , CNNLink Copied!Ad Feedback — The Ingenuity helicopter successfully completed a second flight on Mars Thursday, and it was even more challenging than the first.Ingenuity autonomously flew for almost 52 seconds this time, climbing 16 feet (4.9 meters) up through the Martian atmosphere. After a brief hover, it tilted at a 5-degree angle and moved sideways for 7 feet (2.1 meters).The helicopter hovered in place again to make several turns. This occurred to allow Ingenuity’s color camera to capture images taken looking in different directions before touching back down in the...…By , CNNLink Copied!Ad Feedback — The Ingenuity helicopter successfully completed a second flight on Mars Thursday, and it was even more challenging than the first.Ingenuity autonomously flew for almost 52 seconds this time, climbing 16 feet (4.9 meters) up through the Martian atmosphere.

And these microbes could prove useful.Four strains of bacteria, three of which were previously unknown to science, have been found on the space station. They may be used to help grow plants during long-term spaceflight missions in the future.The study published Monday in the journal .The space station is a unique environment because it has been entirely isolated from Earth for years, so...…By , CNNLink Copied!Ad Feedback — After serving as a home away from home for astronauts over the last 20 years, the International Space Station has become the host for unique bacterial inhabitants.
