BepiColombo launch : Ariane 5 rocket

00:00

send that the very complex singing

00:01

because I'm Pepe Colombo the f16

00:04

instrument on both spacecraft yeah and

00:06

all in all the walls and certain sensors

00:08

and so not only technologies rise also

00:12

from the science it's a very complex

00:13

mission okay we're gonna hear more from

00:15

you when you come back because Johannes

00:18

has never seen a launch excuse me he's

00:20

gonna go out on the terrace with all the

00:22

other other VIPs and give us his

00:23

reactions hot reaction when he comes

00:26

back so don't get lost

00:27

see you later the split-screen image on

00:30

the screen on the left liquid hydrogen

00:32

on the right liquid oxygen these are the

00:34

propellant feeder arms in the middle of

00:36

the launcher we'll get another shot of

00:38

that when we pull back they are putting

00:40

fuel into the upper stage tanks and

00:42

you'll see the arms and you can see them

00:44

there in the center of the screen coming

00:48

out of the of the gantry into the upper

00:52

stage you'll see the arms pull back at

00:54

seven seconds before ignition what are

00:57

the people doing they're going out on to

00:58

the terrorists there because we have two

01:00

terraces on either side of Jupiter that

01:02

give a wonderful view on to the launch

01:05

pad which is about 15 kilometers away

01:07

from us here and that's a minute the

01:11

video is gonna call out

01:13

[Music]

01:16

I filled my in minutes and then we are

01:20

into the final 60 seconds as the crowd

01:22

gathering on the terraces give us a

01:24

chance to say hello to our friends at

01:26

JAXA Tokyo Airbus in Friedrichshafen to

01:29

our industrial partners issa including a

01:32

soccer will go momentarily and knez and

01:35

to all of you following the broadcast on

01:37

the internet we hope you are enjoying

01:39

we're gonna cut away now and let you

01:41

listen to the do as he calls out the

01:43

final countdown

01:44

watch for the cryogenic arms to open and

01:46

enjoy the liftoff

01:49

[Music]

01:59

the attention for the convener this

02:03

nerve we said sis thank God

02:10

Wow do

02:23

we might deserve a garage

02:53

appellation Lumina project to our

02:55

Illumina order engines on fire and

02:59

or video says all is well the two

03:02

boosters now providing 90 that's 900

03:05

percent of our thrust propelling the

03:07

launcher along her trajectory at an ever

03:09

higher velocity 787 a 2-0 tons of lift

03:14

off ends the mass and they get that sort

03:17

of mass or british-made Elana push and

03:19

push we have she's burning five tons of

03:22

fuel every second two and a half tons

03:24

being burned every second in each

03:26

booster plus the core stage burning

03:29

another

03:30

on your kilos of fuel every second

03:33

Ariane 5 putting on quite a show and new

03:37

Mina I can't wait for you on us to come

03:39

back and tell us his reactions the sky

03:41

is clear should be able to see

03:44

separation of elusive may be the

03:46

separation of the fairy will find out

03:47

momentarily Ariane 5 now following up

03:51

around in the on-board computer which

03:53

gives all the orders including state

03:55

separation will soon see that in just

03:57

about 30 seconds from now we are in the

04:01

first of four flight phases the first

04:04

three are powered and will describe each

04:06

in turn so you can follow right now the

04:08

first flight phase the single first

04:11

stage engine and the two boosters are

04:13

burning the boosters will each consume

04:17

there are 240 tons into storage no means

04:20

about 10 seconds they will be the first

04:23

to be extinguished and you'll hear that

04:25

from the devio but you'll see that on

04:27

the screen you'll see the flame out

04:28

there got an object well no me no there

04:33

it as you see you see the main point of

04:35

light in the middle because y'all please

04:38

alight on the on either side all the

04:39

boosters

04:40

that's what looks like up there there's

04:42

another booster on the portside course

04:44

out of camera range but you see the main

04:46

power point of light looks like the moon

04:48

in the middle and on the side the two

04:50

boosters flame French Guiana in part

04:53

chosen as a base for its opening on the

04:56

ocean launching both launches posing no

04:59

threat to the local population of course

05:03

we're waiting for your Hema cell to come

05:06

back

05:07

and our next milestone separation of the

05:10

ferry that's next up as we continue to

05:12

follow Aryan with looks like the ground

05:16

camera

05:17

or the naked eye sip Alessandra plums

05:21

are making or d-d-do has called out

05:23

separation of the fairing and this is

05:27

what that looks like there's another

05:28

half on the starboard side which is

05:31

falling down into the Atlantic as well

05:35

which is a very narrow wide because our

05:37

out of the dense layers of the

05:38

atmosphere of course over a hundred

05:40

metres altitude and you can see on the

05:42

bottom of your screen on the left or

05:44

altitude 140 kilometers and on the right

05:47

are speed 2.4 kilometers per second we

05:53

can also discard any dead weight the

05:55

fairing excuse me weighs two and a half

05:57

tonnes so it's a good idea to get rid of

05:59

it now that we can both Illumina yes

06:03

commander having being treated to a

06:07

wonderful sound and light show on the

06:11

left there is the satellite the white

06:14

boxes well that's fantastic

06:16

I've never seen that before and it was

06:19

great yeah what what what impressed you

06:22

the most was that the sound was a

06:23

delight something I was the brightness

06:25

of the rocket rennet ready to the sky

06:27

and there you couldn't see the rocket it

06:30

was like a big fireball going up to the

06:33

sky and really amazing super did you see

06:37

the separation of the Boosters yes no me

06:40

no great ok so if that doesn't make you

06:42

want to come down here and watch a

06:43

launch ladies and gentlemen I don't know

06:46

what will next up we want to find out I

06:50

mean it's your delicacy I imagine like

06:53

most missions you had some problems

06:54

we're gonna have to go to a film but

06:56

give us give us a first taste in and

06:59

we'll continue after the film any

07:01

problem that you solve that you remember

07:03

Oh Betty Kalama was a bumpy ride from

07:06

the beginning we had issues with the

07:09

solar panels which were not standings a

07:12

combination of heat and solar radiation

07:15

and for that reason we had to make some

07:18

much bigger and Tilton run more than 80

07:21

degrees all right we'll get the details

07:22

on that in a moment

07:23

the first a film on the other milestones

07:27

natella flights maybe you were even here

07:30

in Jupiter for the launch like Johanna

07:32

Swanson

07:33

we were just picked up by our first

07:35

downrange tracking station we promised

07:37

some information on those it's located

07:39

in that tau over the border in our

07:41

neighbor Brazil run by the Brazilian

07:43

Department of Defense afford nests

07:45

integrated with now we are building that

07:50

be Colombo is gonna build on some of the

07:52

science that was discovered by messenger

07:55

the NASA project household yeah before

07:58

the NASA project madam messenger we did

08:01

not know much about mercury on yet data

08:03

from flybys in the 70s and also there we

08:07

could only see one half of the planet

08:09

and even people in the heard about

08:11

biblical um before that's a boring

08:13

target but all that has changed after

08:16

messenger because we found out that

08:19

mercury is a fascinating surprising

08:22

planet with a lot of mysteries which are

08:25

some things which we have never expected

08:26

before

08:27

for example formation temperatures were

08:29

measured which are much lower than

08:32

expected you would expect for a planet

08:34

close to the Sun the temperatures are

08:36

much higher yeah but in actually we

08:38

found them much lower

08:40

comparable to formation temperatures of

08:43

mass so that could be the idea that

08:45

Mercury's forms and well so that would

08:47

be fascinating what what argument did

08:50

they use to say that if it's a boring

08:52

target that no atmosphere no only a few

08:58

craters that didn't expect life on

09:00

Mercury recently was born okay we have

09:05

had cut off of the lower stage and

09:09

separation of the lower stage engine and

09:12

as you can see on the animation ignition

09:14

of the upper stage all on time these are

09:17

three commands given by the on-board

09:19

computer in about 13 seconds so we are

09:22

now into the into the final powered

09:25

flight phase it's the single upper stage

09:28

engine that will burn until plus 25 10

09:31

or another 16 minutes roughly the job of

09:34

the upper-stage

09:35

taking the satellite to its ejection

09:37

point positioning in for separation and

09:40

then releasing it that's its propulsion

09:42

or she also has a second role and that

09:45

comes during area and fives what they

09:47

call ballistics phase our next film from

09:49

ISA an overview on the Pepe Colombo

09:51

mission
