NASA updates its plans for Artemis this week on Planetary Radio.

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

At a NASA press conference last week, agency leaders addressed the status of Artemis II

and announced big changes to the Artemis program.

First you'll hear from Moon to Mars program manager Lori Glaze, as she explains what teams

discovered following Artemis II's wet dress rehearsal, including the helium flow

issue in the interim cryogenic propulsion stage, and why that rocket had to be rolled back

into the vehicle assembly building ahead of its crewed lunar fly-by mission.

Then, from the same press conference, NASA administrator Jared Isaacman outlines a sweeping

restructuring of the Artemis program,

including shifting Artemis 3 from a planned lunar landing to a lunar Earth orbit rendezvous and integrated systems test.

After those remarks from NASA leadership, I'm joined by Jack Corelli, our Director of Government Relations at the Planetary Society,

and Ari Coppell, AAAAS Science and Technology Policy Fellow.

Together, we unpack what's driving these changes to the Artemis program, and whether this

new approach truly moves Artemis forward. And then in What's Up, we look back at Apollo 9, the 1969

Earth orbit mission that proved that the lunar module

could operate independently and rendezvous before NASA actually attempted their landing on the moon.
