Help NASA Hunt For Martian Clouds

Some of the images beamed back to Earth by robotic explorers like Perseverance can make Mars look almost familiar, in an arid desert sort of way. The conditions on the surface are completely alien, though. It’s frigid, and the atmosphere is so thin that clouds are rare, but NASA believes …

Ancient Martian Life

Along with analyzing rocks using X-rays and ultraviolet light, NASA’s Perseverance rover will zoom in for close-ups of rock surfaces that might show evidence of past microbial activity in Jezero Crater, the landing site of the Mars rover. This image was taken by the WATSON camera on the robotic arm …

Martian Storms Zodiacal Light

The zodiacal light is sunlight reflected by interplanetary dust in the inner Solar System. Variations in the zodiacal light with ecliptic latitude reveal discrete bands of dust orbiting near the ecliptic plane. NASA’s Juno spacecraft, in transit from Earth to Jupiter, recorded a sufficient number of impacts with these dust …

Martian Brines

In a new study published in the Planetary Science Journal, a team of U.S. scientists combined experimentally verified data on brine evaporation rates along with a global circulation model to develop a new extensive framework of brine stability on the surface and subsurface of Mars. They found that the equatorial …

Megafloods In Martian Crater

NASA’s Curiosity rover has found a series of symmetrical, 10-m- (33-foot-) high gravel ridges — sedimentologic evidence of ancient giant floods — in Gale Crater on Mars. This artist’s impression shows how Mars may have looked about 4 billion years ago. Image credit: M. Kornmesser / ESO. “We identified megafloods …

Cloud Martian Volcano

Giant Cloud Reappears above Martian Volcano The Visual Monitoring Camera (VMC) on ESA’s Mars Express spacecraft has captured new images of a giant cloud over the 20-km (12.4-mile) high Arsia Mons volcano, the southernmost in a trio of giant Martian shield volcanoes known collectively as Tharsis Montes. These images, taken …

Martian Atmosphere?

ESA’s Trace Gas Orbiter Detects Glowing Oxygen Using data from the NOMAD (Nadir and Occultation for Mars Discovery) ultraviolet and visible spectrometer instrument on board ESA’s ExoMars Trace Gas Orbiter (TGO), a team of researchers has detected green line dayglow emission in the atmosphere of Mars. An artist’s impression of …
