NASA's Johnson Space Center

CHAPEA hits the 150-day mark! 🎉 From harvesting crops to monitoring their physical and mental stressors, the crew of @NASA's yearlong Mars simulation is helping us to drill down how exactly humans will live and work in deep space. Scroll through for a peek inside their mission!

A team in action. 🌟 Flight controllers at NASA's Johnson Space Center in Houston, Texas, continuously staff the International @Space_Station Flight Control Room, monitoring all systems aboard the orbiting laboratory. Today, they're also monitoring two astronauts outside the hatch -- @Astro_Jessica and @Astro_ChrisW -- as they conduct a spacewalk.

Can you spot the astronauts? 👩‍🚀👨‍🚀 The original solar arrays on the International Space Station have a 240 foot wingspan, towering over the crew at the base.

LIVE: Tune in to watch @Astro_ChrisW and @Astro_Jessica go for a spacewalk! Our astronauts are scheduled to step outside the @Space_Station at about 8am ET (1200 UTC) and work for about six-and-a-half hours. twitter.com/i/broadcasts/1…

Exp 74 wrapped final preparations for tomorrow’s spacewalk where two NASA astronauts will exit the space station for solar array upgrade work. The crew prepped spacesuits and reviewed procedures on Tuesday and conducted maintenance and science activities. nasa.gov/blogs/spacesta…

Forget the pot of gold, we found the whole sky glowing green. 💰🍀 Auroras form when energized particles from the Sun collide with gases in Earth’s upper atmosphere, creating waves of color that ripple across the night side of the planet. From 250 miles above Earth aboard the International @Space_Station, astronauts can see these shimmering curtains stretch for hundreds of miles. A perfect view for St. Patrick’s Day!

Teams are now targeting no earlier than Friday, March 20, to roll Artemis II to the launchpad, maintaining the opportunity for an April 1 launch attempt. More info: go.nasa.gov/4utuo8B

The Artemis II crew will fly through a dangerous environment, but they’re not going it alone. Here’s how NASA and the National Oceanic and Atmospheric Administration (NOAA) are protecting explorers from the most powerful eruptions in the solar system. 🛡️ More: go.nasa.gov/4rvmclj

Part of our “road to EVA” is trying on our spacesuit and making sure everything is adjusted just right! Last week @astro_hathaway helped me suit up, just as he will again for @Astro_ChrisW and me on Wednesday’s spacewalk. 🛰️ Join us live as we step outside the @Space_Station! 🗓 March 18 📺 Watch on NASA+, Amazon Prime, or the @NASA YouTube channel ⏰ Live coverage begins at 6:30 a.m. ET 👩‍🚀 Spacewalk scheduled to begin around 8 a.m. ET

“Take time to look.” — Georgia O’Keeffe In a world where life moves pretty quickly, it’s easy to miss moments that deserve our attention. From 250 miles above Earth, NASA astronauts witness our planet in constant motion — weather systems forming, coastlines shifting, and light sweeping across the horizon. Views like this remind us that even in a fast‑paced world, pausing to notice the details can change how we understand and appreciate our home.
