Short Wave · Why scientists launched two little robots to the moon · 19 Jun 2026 podcast

So today on the show, we go from the moon to the farthest reaches of the cosmos. voice-verified

And back. voice-verified

You're listening to Shortwave, the science podcast from NPR. voice-verified

Okay, Scott, Burleigh, I'm going to start with these little cute autonomous robots that, you know, strolled on the moon. voice-verified

So they took a lot of pictures of the moon's surface and of the lander. voice-verified

They're basically scouting out the terrain ahead of bigger rovers and going places they can't. voice-verified

And I talked to Roger Wiens, a planetary scientist who didn't work on this program, and he was thoroughly impressed. voice-verified

He said that the redundancy was a huge benefit to these devices. voice-verified

The group of scientists at Yonsei University in South Korea stands by their work. voice-verified

They already posted a rebuttal to this paper, and they say that the standard way astrophysicists measure universe expansion now is fundamentally flawed. voice-verified

I'm going to let Burleigh do this. voice-verified

And the South Korean team has said, astronomers, we haven't been including the age of the star's home galaxy in those corrections. voice-verified

So the math is off. voice-verified

And when you include that, the final answer is that the expansion of the universe is slowing down, which would be a massive discovery if that were true. voice-verified

Exactly. voice-verified

Yeah, we talked to Priyamvada Natarajan, an astrophysicist from Yale University, who wasn't involved in this work, and she's still skeptical, but she says these kind of debates are what strengthen science. voice-verified

Totally. voice-verified

The crew for the next mission, Artemis 3, was just selected. voice-verified

And this is the mission that will do lots of maneuvers in space, in low Earth orbit. voice-verified

Scott, you spoke with one of the newly selected astronauts, right? voice-verified
