00:00:11,140 --> 00:00:12,518
The Vehicle System Test Bed

5
00:00:12,563 --> 00:00:15,497
is an engineering model version
of the Perseverance rover,

6
00:00:15,518 --> 00:00:18,795
which means is that it has all
the same electronics as Perseverance.

7
00:00:18,998 --> 00:00:21,256
It’s important for Perseverance
to have a twin

8
00:00:21,260 --> 00:00:24,223
so that we have a place
where we can test things

9
00:00:24,224 --> 00:00:26,993
before we actually operate Perseverance.

10
00:00:27,565 --> 00:00:29,868
AZ: Then once we do land on Mars,

11
00:00:29,930 --> 00:00:33,684
we need the twin to test out
all the sequences and plans

12
00:00:33,729 --> 00:00:36,668
that we have for the rover
before we actually send them up

13
00:00:36,708 --> 00:00:38,872
to Perseverance on the surface of Mars.

14
00:00:38,962 --> 00:00:41,744
MS: Also, if we have
a problem with Perseverance,

15
00:00:41,789 --> 00:00:44,695
the VSTB is gonna give us
a place to practice

16
00:00:44,717 --> 00:00:46,585
how we would recover from that problem.

[First VSTB Drive. Sept. 1, 2020]

18
00:00:52,031 --> 00:00:54,284
AZ: This is a really big
milestone for us today.

19
00:00:54,294 --> 00:00:57,296
This is the first time
we’ve ever driven the testbed.

20
00:00:58,295 --> 00:01:00,749
So by driving, we’re validating

21
00:01:00,794 --> 00:01:05,771
that mechanically we can drive
the rover on its own weight on Earth.

22
00:01:06,232 --> 00:01:08,769
MS: The VSTB is now ready
to drive on the Mars Yard.

23
00:01:14,274 --> 00:01:18,545
Today, we’re moving the VSTB from
its assembly facility to the Mars Yard.

24
00:01:18,614 --> 00:01:23,305
[Move to the Mars Yard. Sept. 4, 2020]

25
00:01:39,132 --> 00:01:41,545
(Applause)

26
00:01:41,589 --> 00:01:45,357
MS: I’m extremely proud of
what the VSTB team has accomplished today.

27
00:01:45,366 --> 00:01:48,018
I’m really excited to see
the VSTB out in the Mars Yard

28
00:01:48,067 --> 00:01:50,793
where we can truly test
mobility for the first time.

[First Drive in Mars Yard. Sept. 8, 2020]

30
00:02:01,016 --> 00:02:03,029
MS: Today is a great day for the test bed.

31
00:02:03,039 --> 00:02:06,382
It’s the first time that we’ve driven
Optimism out into the Mars Yard.

32
00:02:06,412 --> 00:02:09,283
We get to actually drive in the dirt
and get this thing dirty

33
00:02:09,313 --> 00:02:10,763
and do some mobility testing.
