Can microbes travel through space on meteorites? It’s an idea called “lithopanspermia,” and to work out if it’s even feasible, some researchers decided to shoot microbes — with a gun. Guests: K.T.

Why did we go back to the moon?

For the first time in over 50 years, humans have gone to the moon and back. And this time, NASA says we're going to stay. NASA's planning for more missions, a permanent moon base, and even a mission to Mars. But there's a pretty big question hanging over all these dreams: Can humans survive in space long enough to make them happen?(A version of this episode originally aired in 2022, with the launch of Artemis I.) Guests: Anne McClain, NASA Astronaut; Scott Kelly, former NASA Astronaut; Rebecca Boyle, science writer, Jonathan Jiang, NASA astrophysicist For show transcripts, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unxtranscripts⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ For more, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unexplainable⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ And please email us! ⁠⁠⁠unexplainable@vox.com⁠⁠⁠ We read every email.

Casey gets his voice back

Casey Harrell is a goofy, lighthearted chatterbox whose love for language helped him become an accomplished environmental activist. In 2020, he was diagnosed with Amyotrophic lateral sclerosis (ALS) and slowly began losing the ability to speak. He sang his last song to his infant daughter and fell into silence. But, now, with the help of 256 microelectrodes implanted directly into his motor cortex, he’s learning to talk once more. It isn’t easy. Guests: Casey Harrell and Levana Saxon.
