Starlink Mission

[Music] [Music] nice launch sector and countdown that pad is clear ten nine eight launch auto sequence has started six five four three two one go for launch vehicle is supersonic stage separation confirmed dragon separation confirmed [Music] stage one is transonic landing lakes have deployed and falcon 9 has landed good afternoon you are watching the 56th starling commission spacex's 36 launch of 2022 my name is yo maizo i'm a dragon propulsion engineer here at spacex and i'll be your host here today we are currently a little early for strongback retract we are currently a little under t minus five minutes from launch and teams are tracking no issues we are lifting off from vandenberg today and while it can typically be very foggy in vandenberg conditions are looking really good with only a 20 chance of violating launch commit criteria we are getting ready for strong back retraction the range is green and ready to support liftoff in just a little over four minutes from now and in preparation for liftoff uh we hopefully should be able to see the clamp arms and te retraction happening here shortly you can see the clamp arms opening just below the fairing there and there is the start of the te retraction again the te is that truss structure that is currently moving backwards that provides fluids and electrical connections to the falcon 9 first and second stages all that waits for launch on the pad it is a beautiful day in vandenberg today and we are just about 30 seconds from the start or the end of our stage one lox load and this is when we'll finish loading the first stage with liquid oxygen and the second stage will wrap up shortly after that stage one lock float complete there is the call out for the completion of the first stage locks loading so that first stage which is the bottom two thirds of the vehicle and is called the booster is now fully loaded with rp1 and liquid oxygen or locks and second stage should finish locks loading in just a little under a minute from now and see really cool views of that cold liquid oxygen causing condensation clouds all around falcon 9 there and the reason we load liquid oxygen and fuel so late into falcon is so that since it's super cold and densified we want to be able to put as much of it into the vehicle as possible which is why we wait till as close to launch as possible to load our prevelance second stage locks loading should be completing here shortly h2 lock flow complete there it is falcon nine is now fully loaded with one million pounds of fuel and liquid oxygen today marks spacex's 174th overall mission and the tenth flight of the booster that you see on the screen in just a few moments here falcon 9 will be in startup and the internal flight computers will take over the countdown falcon 9 is in startup ld is go for launch the launch director has given that final go for launch let's watch falcon 9 get ready for takeoff t minus 15 seconds 10 9 eight seven six five four three two one ignition lift off of the falcon 9. you can run the chamber as you saw we had a beautiful lift off of falcon 9 from vandenberg spacecraft station everything is looking good with falcon 9 falcon 9 is super sonic as you heard falcon 9 is now traveling faster than the speed of sound max q falcon 9 has just passed through max q which is the maximum dynamic pressure that it will feel during flight come back chill we have begun chilling in our merlin vacuum engine on our second stage everything is looking good we are under a minute to main engine cut off stage separation and second engine startup you can see on your left the speed and altitude of falcon 9 right now it is accelerating right now or going almost 5 000 kilometers an hour in a few moments here we will have main engine cutoff stage separation followed by merlin vacuum engine startup and you'll want to watch for fairing deployment happening just shortly after those three events eco state separation confirmed [Applause] you saw main engine cut stage separation merlin vacuum engine startup and there the falcon halves popping off to reveal our stack of starling satellites you can see the cool fairing half floating away on the screen on your right back down towards the earth now today marks the fourth flight for both of those fairing halves that you just saw on screen and we will be attempting to recover them once again after they fall back down to earth with the help of our recovery vessel nrc quest beautiful live views from the first stage on your left and the second stage on your right you can see those grid fins on the first stage and that merlin vacuum engine on your second stage now the first stage booster supporting today's missions now the first stage of today's booster supporting today's mission has previously launched 10 times including crew 1 crew 2 x s x m m8 crs 23 ixpe transporter four and five global star fm15 and one other starlink mission it's got quite a repertoire of launches under its belt you can see the respective speeds and altitudes of the first and second stages on your bottom left and right you can see that the first stage is kind of just coasting there as it is making its way back down to earth whereas the second stage is accelerating under the power of the merlin vacuum engine now as a reminder today's payload is for spacex's satellite internet constellation known as starlink starlink recently went live in estonia so if you're tuning in from that area and interested in service check out starlink.com it's worth noting that starlink is behind some of our much improved landing footage lately if you've watched any of our older launches you'll know that the video feed used to get we used to get back when we used traditional vsat systems were super pixelated and at times were hard to even tell what was going on at all but with starlink which has a much lower latency and much increased bandwidth along with less susceptibility to vibrations it has allowed us to share some really beautiful rocket landings with everyone watching and hopefully we'll be able to see that again today we are just a few page one fts has saved we'll be starting our entryways there is the start of our first stage entry burn this is a about a 20 second burn stage one as your friend shut down we had a good entry burn on our first stage and that was a three engine burn that helps slow that first stage down as it entered the upper parts of the earth's atmosphere you might notice the speed of that first stage both vehicles decreasing significantly as it is coming into the earth's atmosphere foreign in about 30 seconds we should be seeing the first stage landing burn and as you just heard the call out stage one is now uh traveling near or below the speed of sound stage 2 fts has saved stage one landing burn this is the start of our stage one injury burn beautiful view of that drone ship coming into view terminal guides stage one landing light deploy stage one landing is confirmed that was an amazing view of the first stage landing thanks to our sterling satellites and this marks the 57th first stage landing on this particular drone ship of course i still love you and the 56th overall starlink mission landing and 36th launch of this year of the year and back shutdown you just heard the call out for mvac shutdown as well and that was the end of our burn for our merlin vacuum engine on our second stage and we just got a confirmation of a good orbit on our second stage which is carrying our 46 starling satellites into low earth orbit and now with the confirmation of a good orbit and a successful stage one landing we'll wrap up today's launch coverage but as always thanks for watching and be sure to check out spacex social media for confirmation of starlink deployment and we'll see you again soon [Music] you
