SpaceX Launch: Starlink mission

published on July 3, 2020

so let's listen in to the last few

minutes of the countdown

[Music]

HG locks loads closed out

Gragas clothes dirty

how can I start off guys close that

complete

LD is go for lunch

t-minus 30 seconds

few minutes 15 seconds and 9 8 7 6 5 4 3

2 1 yeah ignition

vehicles reaching downrange

it is t+ 45 seconds and we've just had a

nominal liftoff of our Falcon 9 vehicle

carrying our Starlin payload on its way

to its targeted orbit in just about 20

seconds coming up here we will be

passing through max but not as

supersonic that is the maximum

aerodynamic pressure that the vehicle

will see which is the largest structural

load that the vehicle sees throughout

ascent

vehicle is experiencing maximum

aerodynamic pressure and we've just

heard that call out from max Q coming up

next in about a minutes will be three

events

back-to-back starting off with Miko or

main engine cutoff followed immediately

by stage separation and this is where

the first stage separates from the

second stage and then followed by SES

one which is second engine startup and

back-end until and we should be able to

see all three of those events live on

your screen but right now we've got an

awesome view looking aft on the vehicle

with the earth in the background

now if you're just now joining us for

about 30 seconds away from Miko main

engine cutoff stage separation and SES

one or second engine start one

there's that main engine cutoff middle

stage separation confirmed to stage

separation first stage separating from

second stage on your left screen and on

the right second engine startup that's

that an vac engine on our second stage

and there's that bright red glow on the

engine so now coming up in about 20

seconds is fairing deploy and as Lauren

mentioned earlier we will be attempting

to catch both payload fairing halves on

our recovery vessels mystery and

mischeif we well um it will be unlikely

that we will see these live on the

webcast so we'll bring you updates as

they become available but you can also

check in to our social media for updates

as well except eration confirmed and

there's that call out for fairing

separation they're sparing deploy you

can see that on your right screen those

fairing halves are now making or you can

see that on your screen actually the

fairing has are making their way back to

earth and hopefully we can catch those

on our recovery vessels

AOS Bermuda

okay so we have on both sides of your

screen here we got stage one on the left

and stage two on the right so a lot of

really cool stuff coming up all at once

or in rapid succession here in the next

few minutes on the left side what we're

gonna see on the stage one side of

things is at about t plus six minutes

and 24 seconds more or less you're gonna

hear the call out and hopefully visually

see the stage one entry burn that's

where we reignite three of those merlin

1d engines and that allows the second

sorry the first stage to slow down as it

re-enters the upper part of the earth

stations on a nominal trajectory alright

as you just heard stage two is on a

nominal trajectory that's really cool

meanwhile stage one is coasting down

getting ready for that entry burn that

burns gonna last just under twenty

seconds after that entry burn staged one

will continue to coast down towards the

drone ship and at about t plus eight

minutes or so you're gonna hear the call

out for the landing burn that is will

reignite a single merlin 1d engine that

centre engine nine and that slows the

vehicle down to zero velocity and

hopefully you'll see a cool image of it

standing right up on the drone ship

meanwhile stage two continues to perform

nominally wearing that M back is at full

power now right after the stage one

landing about twenty seconds later

you're gonna hear the call out for Seco

one that's second engine cutoff one that

is where we cease to burn the second

stage engine and takes us into our first

Coast phase

that stage two engine is burning with

more than 200 thousand pounds of thrust

as it takes that stack of sixty Starling

satellites to its first parking orbit

Stage one entry startup all right you

see that entry burn as it started

you lost the image but hopefully it'll

come back that introvert was just under

20 seconds long meanwhile stage 2 stage

2 continues to burn and we just heard

the call out that the entry burn on

stage 1 has concluded

Stage two continues on a nominal

trajectory

so we're a little bit under a minute

from the landing burn start me watch

stage two as you just heard continues on

a nominal trajectory Stage one transonic

okay and just under 15 seconds stage one

should start that landing burn stage one

wanna go back

right that landing burn is currently

going unfortunately we don't have the

video from the vehicle but we do have

the judge one line highlight deployed

stage Sue's at terminal guidance and yes

awesome

that's the third landing of this booster

second time landing and of course I

still love you any second now we should

be seeing Seco one that is where that

second stage engine will cut off

got that animation there but let's still

listen out for the done alright as you

just heard second engine shut down low

escape expected and we got confirmation

that we're in a good orbit

alright so we're now gonna enter a co

space so we're gonna take a quick break

all the tips will be leaving you with an

animation that shows where we are in the

co space and we'll be back at about t+

45 minutes for a second stage relight

followed by another brief coast and then

payload deploy hopefully we were to

bring you that payload deploy live on

the webcast so we'll see you back here

in just over 35 minutes

welcome back to the webcast for StarLink

if you've watched our previous Starling

webcasts you are aware that our

satellites are flatly packed with no

dispenser and that the deployment

sequence looks a little bit different

from what you'll see on a typical launch

the satellites will slowly disperse upon

deploy and they may even bump them to

one another which is to be expected the

satellites were designed with this in

mind and we are less than one minute

away from deployment of the Starling

satellites

okay so after the satellites deploy they

are going to over time separate from one

another and use their onboard Krypton

ion thrusters in order to space

themselves out insert or into their

orbital planes and raise their altitude

to their operational orbit of 550

kilometers or insertion orbit orbit if

you remember today is about 290

kilometres above the earth

look at that beautiful view okay well

the one of the the animation school – I

hope they will get back see those live

views from space

Starlin tension rod separation confirmed

okay we just heard the call-out that

separation has been confirmed let's see

if we can get another view

Harrod should be coming up there we go

that's gorgeous that's a 60 Starling

satellite successfully separating from

stage two and that beautiful planet

there is the planet that those

satellites are going to provide internet

service to which is super super exciting

and with that that brings our webcast to

a close we had a successful mission we

had a great stage one ascent completing

the hat-trick launching from three

separate launch sites we had the third

recovery of this booster stage to

deliver its darlink to its operation or

to its targeted orbit and as you just

saw we successfully separated those 60

Starly accelerate satellites so oh and

also we caught a fairing that's a big

deal it's super awesome and we were able

to see it in the daytime which is even

more cool so a big thank you to the 45th

Space Wing or Range Safety and to the

FAA for Licensing's today's successful

watch we'd also like to thank all of you

our viewers
