Artemis 2 and the science of keeping astronauts healthy in deep space. This week on Planetary Radio.

I'm Sarah al-Ahmid of the Planetary Society, with more of the human adventure across our solar system and beyond.

If everything goes well, we're just days away from one of the most exciting moments in spaceflight in decades.

That's the imminent launch of Artemis II,

humanity's first crewed mission to the lunar environment since Apollo 17.

Over the next two shows, we're going to be taking a look at the remarkable science being

done on Artemis II that will shape how we keep astronauts healthy on every deep space mission

to come. We'll start with Steve Platz, chief scientist of NASA's human research program.

He'll walk us through the suite of experiments flying aboard Artemis II.

Steve will explain what we stand to learn about human health and physiology

by sending four humans beyond Earth's protective magnetosphere for the first time in over 50 years.

Then we'll turn to the big picture with Casey Dreyer, Chief of Space Policy at the Planetary Society.

He'll help us make sense of some of the major announcements from NASA's Ignition Day Press

event on March 24th.

We can't cover it all, but we'll briefly talk about the revised plans for Artemis, a bold

vision for a permanent moon base, and a nuclear-powered mission to Mars.

And finally, we'll close with What's Up with Bruce Betts, our chief scientist. We'll explore one of the stranger phenomena in human spaceflight.

The flashes of light astronauts sometimes see that are caused by cosmic rays passing through their eyeballs.
