Why is there not a bobby futuristic-sounding 80s pop song about “Mars In Stereo”? This is something that should already exist.

More please! Luckily my family hasn’t noticed that I’m staring at my iPad with my eyes crossed.

An aurora recently dipped south of the Arctic Circle and put on a show over mainland Nunavut and Hudson Bay.

The nighttime light of the aurora was detected by the @noaa @nasa Suomi NPP satellite. go.nasa.gov/3OTHEik

.@NASA_Orion will reenter the lunar sphere of influence tomorrow, on Dec. 3, making the Moon the main gravitational force acting on the spacecraft.

The spacecraft will exit the lunar sphere of influence for a final time on Dec. 6. #Artemis go.nasa.gov/3OWzsxG

these images are so spectacular!🤩 I love seeing this perspective ❤️


On Saturday, Dec. 3, @NASA_Astronauts Josh Cassada and Frank Rubio will exit the station to install a roll-out solar array. Live coverage begins at 6am ET on @nasa TV. The spacewalk is scheduled to begin at 7:25am and last about 7 hours. ☀️🛰️

so appreciate how accessible NASA activities are!


Life-bringer, nuclear powerhouse, and so very hot—no wonder we study the @NASASun! Today in 1995, @nasa and @esa successfully launched the Solar and Heliospheric Observatory (SOHO) on a four-month journey to the Sun to study everything from its core out to its solar wind ☀️😎

Merging galaxies!
@NASAWebb used two of its cutting-edge science cameras, including MIRI (the Mid-Infrared instrument), to capture these galaxies blending together in a chaotic splash of dust and gas. go.nasa.gov/3ugh9Ky

#OTD in 1990, Astro-1 was launched on the space shuttle Columbia. It was a science platform that carried one X-ray and three UV telescopes. This pioneering mission gave us a nine-day glimpse of the high-energy universe. Read more: go.nasa.gov/3VjYNUJ

As the @NASA_Orion spacecraft prepares for the journey back to Earth, we reflect on all the women who led the Artemis I mission to the Moon.

Through #Artemis, we will see the first woman and first person of color walk on the lunar surface.

in reply to NASA

NASA, how about publicizing and honoring all the women working on this program? Inspire some girls to go into STEM.


This week on #SpaceToGround, a @SpaceX cargo Dragon docks to the station, delivering new @ISS_Research and the solar arrays that will be installed during a spacewalk on Saturday, Dec. 3, while @NASA_Orion is on a course back to Earth after its journey to the Moon.

bothers me that nasa is working with spacex (always did bother me) expecially since what musk has done to twitter.

Lots of Moon action this month—and we don’t just mean Orion’s journey! On the evening of Dec. 1, the Moon will appear very close to Jupiter. A few days later, it’ll cover up Mars and end the month by sliding past Saturn and Jupiter. Our What’s Up! guide has all the details.

are they using aeroponics to grow the tomatoes? And also did they use anything with microbes to help with nutrient uptake? Or are they just testing the nutrients & growth habits ?
