>> nasa hasn't sent a crew of four private astronauts on the axiom one mission to the international space station. up next, we will show you the launch from the kennedy space center in florida. this is about 10 minutes. >> t -15 seconds. 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, zero -- ignition. go, falcon, go, dragon, godspeed axiom one. [applause] >> copy, one-alpha. >> together, and you chapter begins.

godspeed, ax-1. >> propulsion is nominal. >> t+38 seconds on this historic mission. >> stage one, throttle down. >> throttling down in preparation for mack's dynamic pressure. -- max dynamic pressure. >> falcon 9 is supersonic. stage one throttle on. >> merlin one b engines coming

back up. >> copy one bravo. >> this is one bravo, should escape situation arise, the profiles a fly from the super dragon engine, everything is looking good on falcon 9. nominal callouts from all the engineers and a great view from the ground camera and the onboard camera. beginning to chill in the second stage turbo pot in preparation for its ignition, coming up to staff a minute from now -- just half a minute from now. coming up on about 3.5 g's. we will begin firing down the merlin engines to hold that period of acceleration. that's the vent coming up.

we will get main engine cut off. stage separation and ignition of the second stage engine. we are holding 3.5 g's. [cheers and applause] >> successful stage of separation, ignition of the second stage engine on the left. this tenney m grid -- the titanium grid is beginning to slowly deploy. we now deploy a slow flip maneuver. you can see the hydrogen gas balloon as we reorient for entry

back to the earth's atmosphere a little bit later. second stage, we see the nozzle going up. everything continues to look good on the second stage. we should be hearing callouts coming up shortly on how the trajectory is looking. >> dragon speed six, trajectory nominal. >> that's what we like to hear. >> aos bermuda, the bermuda tracking station now getting telemetry from the second stage of the falcon 9 with dragon on top. four minutes, 10 seconds, everything continues to be nominal. we will come back down for landing on the dropship, second

stage partly through its -- to get the crew into orbit. everything continues to look good. >> what an absolutely picture-perfect liftoff. we've got a live view of the crew inside dragon endeavor. looks like everyone is still pretty comfy. as john said earlier -- >> trajectory nominal. >> a good call there, the trajectory is nominal. as john mentioned earlier, we got to 3.5 g's. on the left-hand side of your screen, we can see the first stage as it is making its way back down-to-earth, targeting a landing on our drone ship, a

short call of gravitas, parked several miles off the coast of florida in the atlantic ocean. second stage on the right-hand side, everything continues to be nominal there as the engine is powering the second stage and dragon endeavor to its targeted drop-off orbit. absolutely beautiful views of the first and second stages. >> trajectory nominal. >> [inaudible] >> all right. coming up in about a minute and a half, the first stage will execute the first of two burns required for a landing attempt at about t+ 7 minutes, 30

seconds. the center engine will ignite first and a second later, will ignite to other engines for a total of three engine burns, which will last 29 seconds. the entry burn slows down the vehicle significantly as it enters back into the earth's atmosphere. the first stage sees hydride, 70% of that velocity by the time the landing burn begins. a stunning view, where you can see that curvature of the earth on the left-hand side. >> trajectory nominal. >> [inaudible] >> there you can see the nitrous gas thruster, the puff of gas that you see there occasionally. that is used for altitude control systems. we also utilize those grid pans you see, there are four of them

placed around the booster. those grids help steer for a precise landing. >> going into entry burn startup. >> stage two. >> ok, the entry burn has begun. we are targeting an entry on our drone ship, called gravitas, today. everything is prepared for the second stage on the right-hand side. we are conducting the entry burn . previously the booster -- >> stage one entry burn shut down. >> it was going to any five times the speed of sound, so week -- 25 times the speed of sound, so we slow it down as it enters the earth's atmosphere.

the next event is the second engine cut off, or seco 1, as you see on the timeline of the bottom of your screen. that is where we shut down the back engine for the second engine cut off. >> copy, shannon. >> stage one transonic. >> note that our lending burn and second engine cut off will occur around the same time [applause] >> we have a live view of the crew inside dragon endeavor there on the side of your screen. lending burn -- landing burn has begun. great news there. dragon endeavor, nominal orbit

insertion. >> we copy, it's great to be here. zero g.
