Establishing Crew Exposure Limits of Martian Dust
Background Human exploration of Mars will expose crews to a persistent, fine particulate environment whose physicochemical properties and health implications remain only partly understood. Because no samples of authentic Martian airborne dust have been returned to Earth, NASA must rely on lunar dust toxicology, Martian regolith simulants, and extensive rover/lander geochemical and mineralogical datasets to develop an initial, risk‑informed Permissible…

NASA Rover Detects Electric Sparks in Mars Dust Devils, Storms
Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters. NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam…

Sols 4498-4499: Flexing Our Arm Once Again
Written by Conor Hayes, Graduate Student at York University Earth planning date: Monday, March 31, 2025 Planning today began with two pieces of great news. First, our 50-meter drive (about 164 feet) from the weekend plan completed successfully, bringing us oh-so-close to finally driving out of the small canyon that we’ve been traversing through and toward the “boxwork” structures to our southwest. Second, we…
