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!

Due to weather predictions related to Hurricane Ian, @NASA teams will roll the #Artemis I @NASA_SLS rocket and @NASA_Orion spacecraft back to the Vehicle Assembly Building at @NASAKennedy. First motion is targeted for 11 pm ET tonight: youtu.be/NBKzPd-c0MU

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!
In the first-of-its kind experiment, NASA is about to clobber a small, harmless asteroid millions of miles away to change its path slightly. If successful, the test will show that if a killer asteroid ever heads for Earth, there'd be a fighting chance.

"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.

8/ During Totality, the sky goes dark with a 360 degree sunset (this itself is impossible to describe), birds begin to sleep, and crickets begin chirping and the temperature dives down into night time temperatures.
