00:00:08,360 --> 00:00:06,450
hello my name is Jennifer trois / and I

3
00:00:11,330 --> 00:00:08,370
am the project system engineer on the

4
00:00:13,370 --> 00:00:11,340
Mars 2020 project I'm standing in the

5
00:00:15,230 --> 00:00:13,380
spacecraft assembly facility at the Jet

6
00:00:17,660 --> 00:00:15,240
Propulsion Laboratory where we're

7
00:00:20,300 --> 00:00:17,670
building up the pieces of the Mars 2020

8
00:00:21,679 --> 00:00:20,310
flight vehicle I want to show you some

9
00:00:23,599 --> 00:00:21,689
of the flight hardware we have in here

10
00:00:26,720 --> 00:00:23,609
that's being built right now to the far

11
00:00:29,029 --> 00:00:26,730
left you can see the cruise stage the

12
00:00:33,139 --> 00:00:29,039
cruise stage is the part that gets us to

13
00:00:35,830 --> 00:00:33,149
Mars then next to the cruise stage you

14
00:00:38,209 --> 00:00:35,840
see our descent stage the descent stage

15
00:00:41,420 --> 00:00:38,219
does our powered descent when we're

16
00:00:43,700 --> 00:00:41,430
landing on Mars it is inside of

17
00:00:47,389 --> 00:00:43,710
something we called Aris shell which you

18
00:00:49,790 --> 00:00:47,399
can see over here the eros shell has a

19
00:00:52,310 --> 00:00:49,800
parachute at the top and the parachute

20
00:00:54,470 --> 00:00:52,320
will deploy and slow us down at Mars and

21
00:00:56,510 --> 00:00:54,480
then to the far right what you see is

22
00:00:58,549 --> 00:00:56,520
the heat shield the heat shield is the

23
00:01:01,189 --> 00:00:58,559
part of the spacecraft that faces the

24
00:01:03,709 --> 00:01:01,199
atmosphere it ablates a little and slows

25
00:01:05,420 --> 00:01:03,719
us down and then we jettison it and then

26
00:01:07,250 --> 00:01:05,430
the rover comes down on the bridle and

27
00:01:10,429 --> 00:01:07,260
we land on the surface of Mars

28
00:01:13,070 --> 00:01:10,439
what you see over here may not look like

29
00:01:14,929 --> 00:01:13,080
what it is but this is the beginnings of

30
00:01:18,200 --> 00:01:14,939
the rover that's going to drive on Mars

31
00:01:19,850 --> 00:01:18,210
it has the electronics on the inside but

32
00:01:21,859 --> 00:01:19,860
we don't have the wheels on we don't

33
00:01:23,990 --> 00:01:21,869
have the mobility system on we don't

34
00:01:26,270 --> 00:01:24,000
have the belly pan on all those things

35
00:01:28,060 --> 00:01:26,280
are coming in and over the next several

36
00:01:30,830 --> 00:01:28,070
months we're going to finish the rover

37
00:01:33,200 --> 00:01:30,840
so the next thing we're going to do is

38
00:01:35,569 --> 00:01:33,210
take all of the pieces that you see here

39
00:01:37,580 --> 00:01:35,579
in the cleanroom put them together in

40
00:01:38,450 --> 00:01:37,590
the launch configuration and then we're

41
00:01:40,670 --> 00:01:38,460
going to take them through our

42
00:01:42,440 --> 00:01:40,680
environmental tests so they'll see all

43
00:01:44,569 --> 00:01:42,450
the environments that the spacecraft

44
00:01:47,330 --> 00:01:44,579
will see from launch all the way to

45
00:01:49,830 --> 00:01:47,340
landing on Mars and we are on track for
