  • successful launch orbit and intact reentry have been accomplished by only a few nations to date, the space X mission.

  • Today is the first time an entrepreneurial enterprise has joined this very elite company of space faring entities.

  • Today was a dramatic step cold.

  • We did lift off a 10 43 Eastern standard time.

  • We followed the nominal mission profile.

  • We had First State shut down on time.

  • Stage separation was nominal.

  • Second stage engine start.

  • Uh, nose cone jettison in about three minutes and 37 seconds into the mission.

  • Second stage cut off.

  • Nominal.

  • A swell, uh, nominal separation of the dragon spacecraft.

  • Uh, and then we had our on orbit operations.

  • We did maintain attitude control.

  • Thermal control.

  • Our coms program worked brilliantly.

  • We had connectivity with the Cape Ground Station Wallops Ground Station, Australia Ground Station in Australia.

  • We also had full teachers coverage, both omni and directional.

  • Ah, and the directional t dress required pretty specific pointing of dragon in order to maintain that link, and we achieve that, we maintained it, and it really worked flawlessly.

  • We began the de orbit burn at 22 hours and 32 minutes into the mission we finished that de orbit burn slightly early.

  • The re entry phase began in two hours and 58 minutes into the mission.

  • Our drogue chutes deployed nominally three mains deployed nominally as well, by the way, we achieved in eight meter per second descent speed, which is a Zeeland mentioned quite quite comfortable from landing perspective.

  • Ah, we, uh we believed we would.

  • We projected we would have our water landing at three minutes in 19.

  • Excuse me?

  • Three hours in 19 minutes into the mission.

  • We actually did it in three hours, 19 minutes and 52 seconds, which was awesome.

  • We would not be here without the help of NASA and that that I cannot emphasize that, you know, numbers that were conducted were very similar to sort of universe that we would conduct in going to the space station birthing with space station.

  • Look at your very confident Able Thio conduct the proximity operations of birth operational space station with.

  • If they've been people sitting in the in the dragon capsule today, they would have had a very nice ride.

  • And, um, that would have experienced, you know, maybe up to 4.5.

  • Jeez, about what?

  • You'd see it in amusement park and they would have done quite well.

  • So it's It's, uh, except for the escape system on and you know, it seats and some minor upgrades to the life support system.

  • The vehicle that you saw today could it could easily transport people.

  • Um, you know, we do that way.

  • Do agree with the need to have a launch escape system on the testing of wanted to escape system is ah, a difficult thing.

  • The next generation dragon, We're actually going to be aiming for a propulsive landing with gear kind like Eagle landed on the moon.

  • We're beyond the if you know, is it possible?
