  1. @phalanx How did you know that's where I was going with that? ;-)
  2. Lots of other things may bite us long before the collision becomes a concern. (Not the least of which is we wipe ourselves out first!)
  3. RE: The imminent Milky Way/Andromeda collision: 4 billion years is approx age of Earth & the sun may not even last that long. Bottom line:
  4. OTD 1907, one of the 2 fathers of jet propulsion is born: Sir Frank Whittle. He patentted his idea in 1930 and it flew in 1941.
  5. Breaking News Alert: Milky Way & Andromeda on imminent collision course! (If you define 'imminent' as 4 billion years...) Happy B'day CNN!
  6. ..is derive a list of everything that you think can go wrong. When you see that list you think "It'll be a miracle if it flies!"
  7. Elon is precisely correct: When you deal intimately with rocket & spaceship design & build, one of the things you do...
  8. Congratulations SpaceX! What an incredible accomplishment! I'm Rocky_Sci, and I approve this message.
  9. I'm gonna stop tweeting - gotta watch!
  10. DRAGON SPOTTED!
  11. The plasma surrounding Dragon as it re-enters is blocking any communications from the spacecraft.
  12. Standing (cooly) by waiting for entry interface. I just like saying 'entry interface'...
  13. ..catch the very top of Earth's atmosphere. Drag, thermodynamics & physics take care of bringing it all the way down.
  14. Orbital mechanics 101: The dorbit burn does not lower the Dragon's orbit to intersect with the ground, it only lowers it enough to...
  15. 10 minutes until the heating starts...
  16. Dragon now needs to be in a very precise orientation to survive re-entry. It's about to get 'warm' around the Dragon...
  17. Ladies & Gentlemen: Dragon is coming home! Deorbit burn complete and so is trunk separateion.
  18. BTW, Dragon de-orbit burn will occur at 10:51 am EDT. This is crucial for a safe re-entry. Dragon is currently S of Africa heading ESE
  19. On-board the ISS when Kibo launched was astronaut Garrett Reisman who is now working with SpaceX. An historical intersection.
  20. Happy 4th birthday to the ISS' "Kibo" module which launched on STS-124 (Discovery) OTD in 2008.
