SPACEX / NASA – DM2 Crew Dragon Successful Launch!

published on July 2, 2020

to the liftoff position aunt lifts off

the strong rack will then recline about

45 degrees I started stage two rp1 bleed

launch director called out the strong

back retract has started on the left

you'll see it go back just a couple of

degrees page one are apparently

we are just four minutes away from

liftoff I got at this moment Bob and

Doug are really just laser focused on

those displays they have insight

directly into dragon in the Falcon 9

they're able to see where their fuel

loading is that how everything is

progressing down with the count a FPS

final set up started

three and a half minutes from launch and

a strong back is now reclining away from

the Falcon nine

I'm back igniter purges

oh they'll bleed

dragon has transitioned through terminal

count in his own internal pill stage one

locks load cause that okay we're t-minus

two minutes 42 seconds

Stage one locks load is closed out Stage

two will continue to load for about

another half a minute or so once we get

the completion of stage two locks

loading we have to vent down the line so

you'll see another large white cloud

coming off of the strong rack that'll be

normal that'll happen with all the

transitioning between 1 minute and 40

seconds we're going on internal power

now just a few seconds away from the

stage two locks load being complete it's

been almost nine years since we've been

in this position a lot of work done by

thousands of people to get to this point

all our eyes focused on to now

Stage two lakhs loan is closed out

propellant bills are complete dragon is

an auto Idol stage 2 lakhs load complete

all fuel all oxidizer on Falcon nine one

minute thirty four seconds that go till

launch crown gas close those is starting

Falcon 9 is gonna start up dragon is in

countdown FPS is armed for lunch

under a minute now the FTS the flight

termination system has been harmed

dragon SpaceX go for launch

SpaceX dragon and we're go for launch

let's light this candle

t-minus 30 seconds

stage 1 tanks pressing for flight

t-minus 15 seconds 10 9 8 7 6 5 4 3 2 1

[Applause]

so Rhys got a new era they talked about

in a moment oceans of a new generation

continuing the dream 20 seconds into

flight state one propulsion is nominal

P plus 30 seconds into this historic

mission flying crew up or dragon and

Falcon – look at him go

Falcon pyrometry nominal

and 1d throttle down we're throttling

down to get ready for the period of

maximum dynamic pressure we're in the

throttle bucket

reports say all systems are go

vehicle is supersonic

we've exceeded Mach 1 on the Falcon 9

[Music]

and 1d throttle up

we're throttling back up to full pores

we're through max Q copy one trouble and

we heard that one Bravo call out that's

just the second abort zone that they're

in they'll continue to be on this until

the first age has done its job and they

switch over to the second at this point

Bob & Doug pulling about 23 G's 23

times the Earth's gravity already

blurting it up turn until 1800 miles per

hour we've heard the call out for EM

back engine chill that's giving the

impact engine ready the light that will

come at about 244 in the flight right

now everything continuing to look good

next major event coming up is going to

be the triple will have main engine

cutoff of the nine first stage engines

stage separation and then ignition of

the second stage engine to continue to

carry astronauts into orbit

coming up in about 20 seconds and 1d

throttle down we heard we're throttling

down the merlin engines on the first

stage

and we have Miko because Falcon stage

separation confirmed

[Applause]

and recognition all right we have stage

separation confirm the first stage

beginning its flight back the second

stage being powered by that single

merlin 1d vacuum engine has ignited and

is now very Bob and dug into orbit so

they're gonna continue under the power

of this second stage propulsion is

nominal which will cut off at Seco or

second engine cut off in about eight

minutes and 44 seconds into today's

flight so a little over five minutes to

go still on this second stage you're

hear the call out to alpha so they're

now in the longest abort zone that

carries them all the way from about

North Carolina up the eastern seaboard

almost to Canada things looking good

though getting good call-outs nominal

for propulsion on that second stage

Bobbo continuing to make their way into

orbit

dragon SpaceX nominal trajectory

acquisition of signal Bermuda Bank

dragon nominal trajectory all right here

in nominal trajectories the dragon

pointed in the right direction

continuing to make their flight uphill

hurt acquisition of signal Bermuda

that's one of the other ground stations

that they're using to get telemetry and

data back from this space but they've to

propulsion is still nominal

a little over four minutes 40 seconds

into the flight Bob & Doug flying at

more than 5,600 miles already almost 200

miles downrange from the Kennedy Space

Center nominal trajectory continuing

and while they continue up it looks like

we are getting a view of the first age

as well upon your right screen you can

see that first stage with the grid fins

deployed it's making its way back to

attempt to land on our drone ship of

course I still love you today we're just

about a minute a couple minutes away

from the entry burn and that's where

three of the nine Merlin engines do

ignite to help slow the vehicle down as

it re-enters back into the Earth's

atmosphere and then after the entry burn

will be the landing burn which is just a

single engine SpaceX and orbital

trajectory and you heard nominal

starting chills does that call out they

are still on a nominal trajectory on

dragon still on second-stage and that's

that em back engine on second stage on

your left screen

again on your right screen is that first

stage booster coming back towards our

drone ship of course I still love you

we're about a minute away from entry

burn meanwhile that second stage

continuing to power dragon into orbit

and if you're keeping an eye on that

timer that's gonna continue to burn

until 8 minutes and 44 seconds into

flight so a little over two minutes from

now we'll hear the call-out Seco it will

then be a little duper little more good

a little over three minutes until dragon

physically separates from the second

stage of the Falcon 9 after the upper

trajectory but I could happy nominal

trajectory continuing to check in with

Bob and Doug as they are on a nominal

trajectory just about ten seconds away

from that first stage starting that

entry burn on your right screen we

should be able to see that view live

Stage one entry burn started

and there is that entry bird getting

this burden lasts about 36 seconds long

stage 2 FPS is saved

well that entry burned continues we're

just about a minute away from Seco we'll

have a number of events all happen in

rapid succession the second engine

cutoff they'd want to be looking for

that stage one landing burn shortly

after actually just within a few seconds

of each other it's such a cool view on

your left screen seeing Bob and Doug on

dragon right now you can see the

displays that they are seeing right now

them central guidance I'm back they're

almost up

we are coming up 25 seconds or so away

from Seco or second engine cutoff this

is also the point where Bob and Doug are

experiencing their highest g-force for

seeing the counter tick up to write

about the copy Shannon you heard Shannon

so that just means they're in their

final abort zones if they were to abort

at this point but either being abort to

orbit or to land off the coast of

Ireland standing by for sighted one line

on the confirmation and back Darla step

and back shut down they do in London

where confirmation of Seco second engine

cutoff now we are waiting for our first

stage to make its way to our drone ship

of course I still love dragon SpaceX

nominal orbital insertion what you're

seeing on your screen is a live view of

our drone ship where our first stage

will be coming down looks like we lost

that live view but wait for confirmation

of that landing shortly here docking on

first day successfully and there you can

see on your screen

this is the first falcon 9 to carry to

orbit so very exciting for us and as you

can see on your right screen Bob and

Doug are still making their way to their

targeted orbit I want you to recovery

one so exciting today it doesn't stop it

does not stop all right we did we did

here again that call-out good orbital

insertion so that means Falcon 9 and

Dragon right now exactly where they're

supposed to be can we need a FRC under

everyone and it's right in about 12

minutes when the dragon will separate

looks like we saw a zero-g indicator

floating around there I know Bob and

Doug oh us a little bit about what

exactly that is that they brought up

with them

and before separation before dragon

initiate separation from the second

stage they do make sure to make the they

do ensure that the vehicle is not

spinning and it is in good condition

before we separate that's right the

upper stage does small attitude maneuver

using cold gas thrusters built into the

rocket body itself exactly so we do

expect that separation to occur in about

a minute from now but they do wait until

they have full confirmation that it is

ready to separate such cool views I

cannot get over this view that we are

seeing right now Bob and Doug on the

right screen inside of crew dragon out

in space yeah already 200 kilometers

over planet Earth or a little over a

hundred and twenty four miles traveling

in excess of 2700 meters

27,000 meters per second or about 16,000

miles per hour

again we're just standing by that

separation event should be coming up

shortly and they'll begin a series of

checks on the Draco thrusters that are

going to be used to maneuver and then

power dragon on its flight to the

International Space Station standing by

for separation expected losses signal

Wallops it sounds like we had an

expected ello s lost a signal with one

of the ground stations waiting for

confirmation now of that struggling

separation confirmed dragon separation

confirms there is a great view right in

front of you and there's that call out

dragon is now officially making its way

to the International Space Station today

dragon SpaceX with that separation call

we have a few words for you from our

Falcon 1990 bye dragon chief engineer on

dragon the ground

Bob Doug on behalf of the entire launch

team thanks for flying the Falcon 9

today we hope you enjoyed the ride and

wish you a great mission

thanks Paula congratulations to you and

the f9 team for the first human ride for

Falcon 9 and it was incredible

appreciate all the hard work and thanks

for the great rides of space

cubby oh how I like it proud of you guys

and the rest of the team thank you so

much for what you've done for us today

putting America back into low Earth

orbit up or from the Florida coast

good luck Godspeed

all right so Bob and Doug are in a

second firm nominal eCos activation and

service section Drako checkouts nosecone

deploys in progress kappa yeah we're

monitoring the core here in Hawthorne

giving the crew a heads up that we have

confirmation the nose cone is deploying

so again that nose cone is going to open

up a little bit more than 90 degrees

goes up to about I think 105 degrees and

that's going to expose the actual

docking ring and the hatch that they're

going to be going for
