This is CBS. I am the world. I am John Batchett.

Hotel Mars, episode in. David Livingston, Dr. Space himself is my colleague and co-host.

And we're off to Mars, thanks to Professor Jeffrey Hoffman of MIT and the Department of

Aeronautics and Astronautics, who is part of the Moxie team, one of the very successful

experiments in human history, onboard perseverance, the rover that's been in the news these

last years, wandering Mars, sampling Martian soil, looking for evidence of the Martian epoch.

Moxie, however, is an experiment that was loaded 40 pounds of weight onto perseverance, which

is a lot of weight to carry. So there were great expectations of Moxie. And right now,

we're very pleased that the professor is here to explain to us what it is that they hoped

Moxie would do and what it is Moxie has done. Jeff, a very good evening to you. Thank you very

much for this. When you loaded Moxie onboard perseverance, what were your great expectations?

Could evening to you, Jeff. Yeah, this is fun to be here. I love talking about Moxie.

It's been an exciting episode in my life. You know, I've always been fascinated with space exploration.

I was fortunate enough to be a NASA astronaut for 25 years, made five space flights.

We dreamed as young astronauts coming in only six years after the end of the Apollo program that

it wasn't going to be too long before, you know, people would be going on to Mars. And, you know, all

it was going to take was another president. But of course, it didn't quite work out that way.

I have no complaints. I had some great flights on the shuttle, fixed the Hubble Space Telescope.

But still love to see people get to Mars someday. You know, right now, the big push is to reestablish

our ability to work on the moon, which I think is the right way to go about it. Because gosh, it's been 50 years since we've been on the surface of another planetary body.

But Mars is so fascinating. I mean, all the probes we've sent there, as you mentioned, there was a time in the history of Mars where it may have been very much like the early Earth.

We're doing great explorations with our robots. And then I love robots on Mars everywhere. I mean, they take us places we can't go.
