Behind the black Bob's woman is here. I'm John Batcheter. We're going to the surface of Mars with Percy, otherwise known as perseverance and something's been repaired. What is that Bob?

Yeah, one of the camera spectroscopy instruments on the robot arm had a problem six months ago.

Its camera cover got stuck halfway open and they couldn't use it anymore. And so they spent the last six months

troubleshooting this thing and they finally got the, they shook the arm basically and got the

cover to open so that they could use this camera and spectroscope.

However, with the cover stuck open,

they can't focus the camera and the spectroscope anymore.

So the way they're going to focus it is, and they spent a few months of two, using the robot arm to find out a precise distance, this arm has to be from an object to get a focused picture. And so they found that if they put the arm 1.58 inches away from the ground

they'll get a sharp picture and so they've done that so they fix the instrument and this is a key

instrument for doing close-up geology on Mars John so they got a

fixed it's good thing. This reminds me how I used to fix my computers I would

unplug it and plug it back in Bob or always work. Well I'm so more complicated because they had to do a lot of maneuvering with the robot arm to shake

that cover open and then they had to do multiple, multiple pictures at different distances until they

found the distance that was shopping.

So it was nice work, nice work by the person.

Sometimes after I plugged and unplugged it, I would hit it.

That would also work.

High-tech engineering. Okay, we're off to juna which is in orbit

around Jupiter what is it seen by this is using data from the various flybys most

specifically a flyby of the moon I.

In May of 23, I always the one with all the volcanoes.

Scientists have said that those, that the infrared data located at least 11 active lava lakes on I.
