This is CBS. I am the world, Bob Zimmerman. He keeps a website behind the black. It's holiday, fundraising time for behind the black.

0:11.0

And Bob is here. Your subscriptions, your donations are hardly welcome because we're going to the planet Mars.

0:17.0

Not only to the planet Mars, but it's a great treat to introduce once again that champion of the Martian atmosphere in Genuity, number 64.

0:26.0

Anything significant, Bob? Speed record, altitude record? No, no record at all here, John. It just was a standard flight as I said behind the black.

0:35.0

In a pattern, it's almost beginning to almost be routine. They flew on October 27th, about 1,300 feet.

0:42.0

And the helicopter basically positioned itself in the valley, in the right of our valley, that is the gap in the rim of G-Zero Crater.

0:55.0

Essentially, it's beginning to do the scouting work for Perseverance. When Perseverance moves into this valley to leave the crater and go into the regions beyond to the west of G-Zero Crater.

1:08.0

And that's what's significant, and it's just doing scouting work. And for example, just before it landed, it took a color oblique picture of the terrain of the Red Vivalus.

1:18.0

And I posted that as well, so you can see the ground of this, what looks like a former stream bed, dry.

1:26.0

And you can see the ground that the rover will be going on. It's not particularly difficult.

1:31.0

That's the colors that were provided by the picture. I increased the contrast slightly. I didn't change the colors.

1:44.0

I don't know if that's a natural color or not. I really don't. That's the colors that the color camera on ingenuity produces routinely.

1:53.0

What about the blue skies? Yeah, I don't know. That's the colors it produces. I mean, that's my understanding.

1:59.0

On every other image of the scene, the sky of Mars has a pink glow. So I have a feeling that's just the circumstances of the camera. I don't get it.

2:09.0

Unless it's in less ingenuities in San Diego, that would make it. I'm not going to that job.

2:17.0

A global map of the near surface ice on Mars. You will remember the last time, Bob,

2:23.0

explicated what is looking to be the starship landing zone on Mars, because there was a lot of surface ice.

2:30.0

Now, do they know where all of it is, Bob?

2:33.0

This map is essentially taking global, the global orbital data from many different spacecraft,

2:42.0

combined with some of the ground data that we have, though most of that's in the dry equatorial regions.

2:48.0

But so the orbital data basically tells us where it appears there is ice on the surface or near surface of Mars.

2:54.0

And so they've mapped it. They decided to produce a decaled map. So we know what areas to look for.
