Starlink Mission
iceland 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 stage one is transonic landing lakes have deployed and falcon 9 has landed good evening i'm kate tyson i'm the quality systems engineering manager here at spacex i'll be your host for our 59th

starlink

mission

and spacex's 39th launch of 2022. tonight our

starlink

satellites are lifting thanks are pressing for strongback retract our sterling satellites are lifting off from pad 4e in vandenberg space force base california teams are currently tracking no issues and weather conditions are looking good the range is also green and ready to support liftoff in just about four and a half minutes from now and in preparation for liftoff as you just heard moments ago we are preparing for uh te retraction you can see that the clamp arms are now opening there just under the fairings we began loading propellants about 30 minutes ago right now falcon 9's first stage and second stage are still loading their liquid oxygen or locks the vehicle is fully loaded with all of its rp1 or liquid kerosene and as you can see there that strong back is retracting we're expecting the first stage to wrap up its lox load at t minus 3 minutes so just under 30 seconds stage one locks load is complete as you just heard the first stage has wrapped up uh loading of the liquid oxygen...
starlink mission
second stage will finish its locks load in under a minute from now as i mentioned the vehicle is already fully loaded with its rocket grade kerosene or rp1 about 30 seconds until second stage locks load is complete stage two and with that falcon 9 is now fully loaded with one million pounds of fuel and liquid oxygen this

marks the seventh flight for the booster that you see on screen previously having supported sentinel michael froelich dart and four

s as a reminder today's

mission

is for

starlink

and we will be sending online we'll be sending another 46 satellites into low earth orbit ld is go for launch t minus 30 seconds 15 seconds minus 10 9 8 7 6 5 4 3 2 1 again stage one propulsion is nominal power and telemetry nominal falcon is now supersonic as you just heard falcon 9 is traveling faster than the speed of sound max q and there's the call out that falcon 9 has reached max q the maximum dynamic pressure that the vehicle will feel during flight mvac engine chill has started we're under a minute until main engine cutoff stage separation and second engine start we just heard the call out that mvac chill has begun the vehicle is flowing a little bit of that super chilled liquid oxygen into the turbo pumps on the second stage engine in preparation for its ignition main engine cutoff stage separation confirmed and back ignition bearing separation confirmed and there you can see that those fairings have deployed and the grid fins...
starlink mission
have also just deployed there on the first stage on the left hand side of your screen today marks the third flight for both of those fairing halves and we will be attempting to recover them once they fall back to earth with the help of our recovery vessel nrc quest the western coast of california just coming out of view on the left hand side of your screen with those city light city lights in the background as you can see by the telemetry at the bottom of your screen the first stage is still a nominal trajectory the first stage is still increasing in altitude just a little bit so even though it has already separated from the second stage it still has a little bit of an upward journey before it reaches its apex or apogee and at which point in time it will then begin to return to earth for its landing on our drone ship of course i still love you as a reminder today's payload is for spacex's satellite internet constellation

we can now see from the telemetry at the bottom left hand side of your screen that that first stage is now making its way back towards earth we are about 30 seconds away from entry burn on the first stage everything continues to look nominal with the first and second stage stage one fts has saved stage one at your friend's startup as you can see there stage one has ignited three engines to slow it down for atmospheric re-entry this burn should last about 20 seconds we have reignited two of the radial engines and the center engine as you...
starlink mission
just saw there that has concluded falcon 9 is using its on-board computers to guide itself autonomously back to or down to the drone ship which is parked in the pacific ocean a couple hundred miles off the coast of california we're less than one minute away from landing burn of the first stage stage 1 transonic as you just heard stage 1 is traveling near the speed of sound stage two fts has saved stage one lighting burn there you can see stage one has lit one engine the center engine to prepare for landing on our drone ship you can start to see in the background here stage one letting light deploy stage one landing is confirmed all right and as you can see there falcon 9 has landed this marked spacex's 58th first stage landing on our drone ship of course i still love you and our 39th launch of this year shut down nominal orbit insertion and as you just heard there we had a good second engine cut off as well as a good orbit at this point in time stage two is now carrying 46
