The teamwork across @NASA made today's #Artemis launch possible!
Hear from @NASAGroundSys red team, who traveled out to Launch Complex 39B during today's launch countdown to address a leak.
👏Three cheers for you three!

This mission may not have the attention the Mars 2020 rover landing captured, but can we all get a little more excited for DART? This is “dream big” level stuff right here!

"be a zero" @Cmdr_Hadfield via @SeanInMotion
from his book "An Astronaut's Guide to Life on Earth, Cmdr. Hadfield explains that to a contributor to any team you should first aim to not add or subtract anything from the group. find a stasis, get your bearings, then add value.

10/ 77 seconds later the sun shifts to a it’s 3rd stage and a phenomenon called Bailey’s Beads or the Diamond Ring begins. As the sun peaks out behind the moon the light patterns form a diamond ring and protective lenses need to quickly come back on.

9/ During the 2 minutes, 27 seconds of Totality only the corona peaks out behind the moon. It’s now safe to remove your glasses and look directly at the sun (the only time it’s safe). It doesn’t look real.
