A @NorthropGrumman rocket launches to the International Space Station next week, carrying a space toilet, radish seeds and a camera that will film a spacewalk in VR for the first time. Ask the people behind these projects anything in Reddit AMAs this Friday, Sept. 25. nasa.tumblr.com/post/630058321…

To improve fire safety in space we need to understand how different fuels interact with materials in microgravity. Last week, an ISS Research experiment safely lit 21 flames on International Space Station, this time using methane as the fuel. Learn more: go.nasa.gov/33UHhyf

The hatches are open and NASA's SpaceX Crew-1 astronauts Shannon Walker, NOGUCHI, Soichi 野口　聡一（公式）, Victor Glover, and Mike Hopkins are the newest residents aboard the International Space Station. Welcome aboard!

The Crew-1 astronauts have now been at their new home, the International Space Station, for a week! Throughout their stay, they’ll conduct many microgravity studies including 👨‍🚀 How spaceflight affects our bodies 🌱 Growing radishes in space 🌟 Testing tissue chips ➡️go.nasa.gov/2UBjFsH

Science teams are preparing awe-inspiring ISS Research to launch on SpaceX CRS-21.

🚀LAUNCH SUCCESS! 🐉 The latest SpaceX Dragon resupply spacecraft is now on its way to the International Space Station with more than 6,400 pounds of science investigations and a shiny new airlock! go.nasa.gov/3os2Ehv

A new era of space exploration! We just announced the NASA Artemis team of NASA Astronauts that will help pave the way for our next human missions on and around the Moon 🚀🌕 nasa.gov/artemisteam

TONIGHT ✨ Look up to witness an end-of-year treat! This evening, Jupiter and Saturn will appear a tenth of a degree apart — an astronomical event known as a “Great Conjunction.” Want to learn when & where to look up? Watch this #NASAScience Live episode: youtu.be/yvQgisEBql0

Glad to see NASA will be offering this program virtually again in 2021. Come learn how we do space research. #summerinternship

Last radish harvest of the year!

President-elect Joe Biden lays out 5 big questions about the future of science and technology. Answering them will take everyone — scientists, technologists, and the public — working together! #Scienceisback! buildbackbetter.gov/wp-content/upl…

No team could have prepared me better for what’s to come. Whatever Mars throws at me, I’m ready as I’ll ever be. #CountdownToMars Status updates: go.nasa.gov/3dRnPp8

Can’t wipe the smile off my face today. Tune in to watch Perseverance land on the Martian surface loaded full of science instruments, including 23 cameras.

This week astronauts worked to assemble new critical station hardware. Two cosmonauts will exit the station for an upcoming spacewalk to prepare the station for a new science module. #SpaceToGround

The International Space Station is full of life! 🌷🌱🐟🕷️ From flowers and veggie plants to fish and spiders, numerous experiments have launched and observed how life forms beyond humans respond to space.

.Mark T. Vande Hei is back on Earth after a NASA record-breaking 355 days in space! Next he will fly from Kazakhstan and return to his NASA's Johnson Space Center home base in Houston 24 hours later.

BIG NEWS: Researchers grew plants in lunar soil for the first time! 🌱🌖 Congrats to FLORIDA on growing Arabidopsis plants in regolith collected during the Apollo era. We’ll study the same species on #Artemis I as we prep to return to the Moon. go.nasa.gov/3L1Yx6P

This week I joined teams from NASA astrobiology, geology, chemistry, and engineering in the field. Scientists are conducting research, developing methods, and testing hardware for the Moon and Mars. Follow along NASA Expeditions to learn more!
