I'm bringing back my #Apollo11 LIVE TWEET! From July 16-24, my feed will be reliving the mission, from big mission events to tiny human moments, exactly when and as they happened (with a 50-year time delay) It's going to be a lot, but super fun! 🚀

If you're curious, #Apollo11 crew heart rates at launch: Armstrong, 110; Collins, 99; Aldrin, 88. Compared that with each man's first Gemini launch heart rates: 146, 125, 110 respectively.

Collins: "Jesus Christ, look at that horizon!" Armstrong: "Isn't that something?" Collins: "God damn, that's pretty! This is unreal. I'd forgotten." Then he grabbed a Hasselblad that had floated away and snapped this beauty. #Apollo11

Duke: "Eagle, Houston. If you read, you're Go for powered descent. Over." Collins: "Eagle, this is Columbia. They just gave you a Go for powered descent." #Apollo11 is GO for the MOON!!!

Armstrong: "Engine arm is off. Houston, Tranquility Base here. The Eagle has landed." Duke: "Roger, Twan-- Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot." Simultaneous scenes from #Apollo11

To all those asking whether an asteroid is going to hit and destroy the Earth next week, the answer, sadly, is no. But don't give up hope.

How close will my closest approach be during #EarthGravityAssist? I'll fly pretty low for a spacecraft, but still ~11,000 miles from Earth.

Amazing! I never had any doubts! x.com/SpaceX/status/…

Amazing Job SpaceX and all involved! #FalconHeavy Here is to the future of spaceflight!
