Free Spirit, A New Friend in the Sandbox

[00:00:06]
I'm Ashley Stroupe, one of the Mars rover drivers for Spirit
and I'm here with the latest Free Spirit Update.

[00:00:11]
We've started doing a very interesting set of tests.
We've brought in a new rover.

[00:00:16]
This rover is lighter weight than the regular rovers.

[00:00:18]
And that actually models how much the real rovers weigh on Mars.

[00:00:23]
Because Mars has only 38 percent the gravity that we have here on Earth.

[00:00:27]
We're testing it on several different kinds of soil so that we can build the model of how the rover interacts

[00:00:32]
with different kinds of soil and that will help us predict what the rover is going to do on the Mars soil when we start extraction.

[00:00:39]
After these tests, we're going to be doing some extraction testing

[00:00:42]
where we will be doing long sequences of maneuvers, which hopefully will help get Spirit out on Mars.

[00:00:47]
Once we see which of those sequences of moves works the best, we'll then be able to implement those on Mars.

Text: Spirit's view of the sun and sky on Sol 2005
Spirit is experiencing a small dust storm and there's been a slight drop in power.

[00:00:57]
We were hoping that's going to blow over soon and to be back to her normal power levels.

 

[00:01:02]
On the other side of the planet, Opportunity is still investigating the fascinating meteorite that we found

[00:01:07]
which has told us many interesting things, including giving us some insight as to how dense the atmosphere of Mars must've been a long, long time ago.
