Artemis III will be one of the most complex test missions in NASA history.
Launching in 2027, Artemis III astronauts will practice rendezvous and docking with two commercial lunar landers designed to carry crew from the Orion spacecraft to the lunar surface.

YouTuber @MouldS hypothesized that a circular loop of chain would exhibit circumferential waves as it rotated in the absence of external forces, flowing through its own shape.
In gravity, this creates the chain fountain effect, popularized with his science videos. Aboard the ISS, I helped test his theory!
These loops were made from beaded chain and our EVA French clips used to tie things down during spacewalks. I wore nitrile gloves to prevent the chain from sticking to my fingers. It took many tries to produce this!
A full video of our findings is now posted to his channel, which I have linked in the comments.
Congrats, @NASARoman team — what an amazing launch! We are excited to follow the telescope’s journey to L2 and can’t wait to see what it reveals about the universe.
Pleased to share my favorite photo from yesterday morning.
Shot using 3 cameras from a parking lot: this is the Falcon Heavy carrying Roman Space Telescope transiting the sun.
More about how it was captured and a video of the transit 👇
Remember to take the lens cap off! 📷
Roman has a “lens cap,” just like your camera, but instead of coming off, it folds out like a visor on a hat. Our deployable aperture cover has also been released, protecting Roman’s instruments from the glare of the Sun.
