SpaceX completes its first commercial mission to space

Ten, nine, eight- Seven. six, five, four, three, two, one. Zero. Ignition [INAUDIBLE] [SOUND] [INAUDIBLE] [APPLAUSE] [INAUDIBLE] It was 33 seconds into flight. Under the power of 5.1 million pounds of thrust Falcon Heavy is headed to space. We're throttling down to T plus 40 seconds to prepare for maximum dynamic pressure. [BLANK_AUDIO] Power and telemetry are nominal. [BLANK_AUDIO] We're hearing reports, power and telemetry are nominl. [BLANK_AUDIO] Vehicle supersonic. You may have heard the call out on Net One, vehicle is supersonic, side boosters are throttling back up on power as we're through the period of maximum dynamic pressure. [APPLAUSE] [APPLAUSE] Trajectory looking good. You can hear the applause behind me as we've gotten past maximum dynamic pressure. [APPLAUSE] Merlin engine performance looks good. [APPLAUSE] We've begun dropping power on the side boosters. To decrease loads on the center core. [APPLAUSE] Successful separation if you can hear me over the cheering. Side booster is now beginning a flip. to begin we are turning back to Cape Canaveral, side boosters have begun the first back burn, the center core has throttled back up to power, everything looking good on the fight of Falcon Heavy, the next major event Main engine cut off of the center core, and separation ignition of the second stage. Bottom middle view shows the view looking up into the nozzle of the second stage engine. [BLANK_AUDIO] Miko. Main engine cutoff, center core shut down. Stage separation confirmed. [APPLAUSE] MVac ignition. [APPLAUSE] Again, over the cheering, MVac V engine up on power, it looks good Side boosters working good, still burning on their way to Cape Canaveral. Grid fans are out on the center core. Fairing seperation confirmed. Here comes the fairing seperation, and there it goes. [APPLAUSE] We also have successful shutdown. Of the side booster boost back burn. So T plus 4:25 in the flight, side boosters on their way back to Cape Canaveral. Center core coasting out over the Atlantic. Stage two trajectory nominal. Stage two looking good with a nominal trajectory. [BLANK_AUDIO] As a reminder, today we'll be attempting to recover all three of the first stage course. And all three boosters are currently on their way heading home. In just a few minutes the side boosters will execute an entry burn, followed by a landing burn. And the center core will do much the same a few minutes later. Both bones are meant to slow the stage's speed down rapidly before landing. At the time of separation, the [UNKNOWN] were travelling slow enough to turn around and make their way back to land at their side by side landing pads. The [UNKNOWN], on thbe other hand, is going too fast to efficiently return to the [UNKNOWN] so we're using our autonomous drone ship. Of course, I still love you If we have a successful landing today, the side boosters will be re-flown on our next falcon heavy mission TSP2. [PAUSE] Coming up in about five seconds here, the side boosters landing burn will be begin as well. [APPLAUSE] [APPLAUSE] [INAUDIBLE] an amazing view We can hear the crowd going crazy right now. [UNKNOWN] has landed on our landing pads. Zone one and zone two, what an amazing sight to see. [APPLAUSE] Now we're waiting for the engine to shut down on the second stage. [INAUDIBLE] all goes well, we'll have successfully recovered all three boosters which we have never done before. [BLANK_AUDIO] Now coming up in about 20 seconds we're gonna listen for confirmation of SECO 1 or second engine cut off one. Attention [INAUDIBLE] [APPLAUSE] It's like we [UNKNOWN] [APPLAUSE] Waiting for some confirmation and it sounds like we landed the center core on our [UNKNOWN] We have landed the center core for the first time on our [UNKNOWN] I still love you. For the first time we've landed all three boosters [UNKNOWN] heavy. What an amazing Day. [APPLAUSE] So now we are going to take a quick trip- [APPLAUSE] Do you hear out crowd going wild? [APPLAUSE] three for three boosters today on Falcon Heavy. What an amazing accomplishment. We're about half a minute away from the deployment of the Arabsat-6A satellite. Now currently the second stagstage has begun a slow spin up that will help stabilize the satellite it will retain that spin when it separates from the second stage. And currently view has switched forward looking at the Ara/F 68 spacecraft. And if you've just joined us now you've missed a great day Well, side boosters landed at the cape, center core landed, second stage right in the desired orbit and now we're waiting for separation. [BLANK_AUDIO] Spacecraft separation confirmed. [APPLAUSE] As you can tell, behind me The folks who have watched the mission cheering. [APPLAUSE] Arabsat-6A [APPLAUSE] Headed away into the desired orbit doing its mission in space. That puts a capper on what's been a completely norminal day here at SpaceX.
