International Space Station

Four Exp 74 crew members enjoyed a light-duty day following yesterday’s spacewalk while three orbital residents inspected various modules, cleaned, and stowed cargo on Thursday. More… go.nasa.gov/4rJCVBD

On March 22, an uncrewed Progress 94 resupply spacecraft will lift off to bring fuel, food, and supplies to the @Space_Station. Learn more about how you can watch it launch and dock: go.nasa.gov/4soCAFE

#OTD in 2001, our team at #NASAMarshall began 24/7 support for science on the @Space_Station. This partnership has resulted in over 4,000 different scientific investigations and breakthroughs! Learn more as we celebrate this 25-year milestone: go.nasa.gov/4skSmkQ

.@Astro_Jessica and @Astro_ChrisW concluded a seven-hour, two-minute spacewalk today at 3:54pm ET. The duo is back inside the space station following the installation of a solar array modification kit to the port side of the orbital complex. nasa.gov/blogs/spacesta…

@prettyreznik The spacewalkers are installing the kit on the port side of the station to ready for the next roll-out solar array to be installed during a later spacewalk.

@Space_Station what's the real reason they're installing a solar array modification kit?

.@Astro_Jessica and @AstroChrisW powered on their spacesuit batteries at 8:52am ET and are now exiting the space station, beginning their six-and-a-half hour spacewalk to install a solar array modification kit. nasa.gov/blogs/spacesta…

Live coverage is underway as two NASA astronauts get ready to exit the space station for a six-and-a-half hour spacewalk to complete solar array upgrade work. nasa.gov/blogs/spacesta…

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…

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!

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…

LIVE: We're giving a preview of our next two spacewalks, taking place outside the @Space_Station on March 18 and April 1. twitter.com/i/broadcasts/1…

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

Exp 74 spent Monday gearing up for this week’s planned spacewalk, prepping spacesuits and configuring tools. Some crew members also worked routine station maintenance and monitored their heart health. More… go.nasa.gov/3P3ud3D

After an eight-month stay at the space station, the unpiloted Roscosmos Progress 92 spacecraft undocked from the station’s Poisk module at 9:24am ET today. nasa.gov/blogs/spacesta…

Exp 74 configured space biology and Earth imagery gear then measured crew heart, lung, and brain activity today. The station is also orbiting higher after a cargo spacecraft fired its engines. nasa.gov/blogs/spacesta…

#ICYMI: @NorthropGrumman's Cygnus XL spacecraft was released by the Canadarm2 robotic arm from the International Space Station at 7:06 a.m. EDT on Thursday, March 12, completing its cargo resupply mission. More... go.nasa.gov/4ur6Gtg

Another day on the @Space_Station brings the departure of another vehicle, the last of our 3 cargo vehicles on the US Operating Segment (USOS). Today we bid farewell to the @northropgrumman Cygnus NG-23 cargo vehicle, named after our late colleague NASA astronaut Willie McCool. As I watched Cygnus disappear over the horizon, I took a moment to reflect and honor Willie, and all of the STS-107 crew, who honorably gave their lives in their effort to advance science and space exploration. Godspeed S.S. William “Willie” C. McCool, thank you for your service! 📷 — The Northrop Grumman Cygnus NG-23 cargo vehicle sits grappled by the @csa_asc Canadarm, awaiting its release. This cargo vehicle delivered valuable scientific experiments, hardware and supplies for all of us on the ISS. At the end of its mission, it is now full of trash which will burn up in the atmosphere.

How to make planet Jupiter: 1) be on the @Space_Station 2) make a thin film sphere of water 3) add food coloring 4) blow on the edge to create swirls This is way cool!
