Nearly 54 years after the last crewed mission to the moon, NASA’s Artemis II took off Wednesday from Kennedy Space Center. This mission won’t land any astronauts on the lunar surface, but will perform a flyby before swinging back home.

Science journalist Maggie Koerth joins Host Ira Flatow to talk about how the mission has gone so far, a surprisingly unsalty discovery underneath the Great Salt Lake, and why gloves worn in the lab might be skewing microplastics data.
