NASA’s Mars Curiosity rover ran over a rock, which cracked open to reveal pure sulfur crystals. This was the first time pure sulfur has been discovered on the planet. The rover found many other similar rocks nearby, raising questions about the geologic history of the location.
Ira talks with Alex Hager, who covers water in the West for KUNC, about Martian sulfur rocks and other top science stories of the week, including melting glaciers increasing the length of the day, life rebounding at Lake Powell, a rare whale and new research on how psilocybin rewires the brain.
