00:00:14,070 --> 00:00:12,799
the vehicle system testbed is an

3
00:00:15,910 --> 00:00:14,080
engineering model version

4
00:00:17,670 --> 00:00:15,920
of the perseverance roller which means

5
00:00:19,670 --> 00:00:17,680
that it has all the same electronics

6
00:00:21,269 --> 00:00:19,680
as perseverance it's important for

7
00:00:23,349 --> 00:00:21,279
perseverance to have a twin

8
00:00:24,790 --> 00:00:23,359
so that we have a place where we can

9
00:00:27,830 --> 00:00:24,800
test things before

10
00:00:30,470 --> 00:00:27,840
we actually operate perseverance

11
00:00:31,349 --> 00:00:30,480
then once we do land on mars we need the

12
00:00:33,750 --> 00:00:31,359
twin to

13
00:00:35,270 --> 00:00:33,760
test out all of the sequences and plans

14
00:00:36,870 --> 00:00:35,280
that we have for the rover

15
00:00:39,110 --> 00:00:36,880
before we actually send them up to

16
00:00:40,630 --> 00:00:39,120
perseverance on the surface mars

17
00:00:42,549 --> 00:00:40,640
also if we have a problem with

18
00:00:44,709 --> 00:00:42,559
perseverance the vstb

19
00:00:48,730 --> 00:00:44,719
is going to give us a place to practice

20
00:00:53,910 --> 00:00:52,069
[Music]

21
00:00:55,430 --> 00:00:53,920
this is a really big milestone for us

22
00:00:56,150 --> 00:00:55,440
today this is the first time we've ever

23
00:00:59,830 --> 00:00:56,160
driven

24
00:01:02,310 --> 00:00:59,840
the test bed so by driving

25
00:01:04,950 --> 00:01:02,320
we're validating that mechanically we

26
00:01:07,590 --> 00:01:04,960
can drive the rover on its own weight

27
00:01:14,390 --> 00:01:07,600
on earth the vstv is now ready to drive

28
00:01:29,550 --> 00:01:16,550
today we're moving the vstb from its

30
00:01:45,350 --> 00:01:43,990
i'm extremely proud of what the vstb

31
00:01:47,190 --> 00:01:45,360
team has accomplished today

32
00:01:48,789 --> 00:01:47,200
i'm really excited to see this vstv out

33
00:01:56,210 --> 00:01:48,799
of mars yard where we can truly test

00:02:02,789 --> 00:02:01,350
[Music]

35
00:02:04,149 --> 00:02:02,799
today is a great day for the test bed

36
00:02:06,230 --> 00:02:04,159
it's the first time that we've driven

37
00:02:07,830 --> 00:02:06,240
optimism out into the mars yard

38
00:02:08,949 --> 00:02:07,840
we get to actually drive in the dirt and
