In a new study, researchers say that non-biological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by NASA’s Curiosity […]

During the rover’s recent investigation of the bedrock at “Vernodden,” Perseverance encountered an unusually shaped rock about 80 centimeters across (about 31 inches) called “Phippsaksla.”
We present an analysis of atmospheric pressure variability inside Jezero Crater on Mars based on measurements from the MEDA meteorological station aboard NASA’s Perseverance rover.
Scientists from New York University Abu Dhabi (NYUAD) have uncovered new evidence that water once flowed beneath the surface of Mars, revealing that the planet may have remained habitable for […]
The incident ultraviolet (UV) irradiance on the surface of Mars is strongly sterilizing and plays a critical role in atmospheric and near-surface photochemistry.
New findings from NASA’s Curiosity Mars rover could provide an answer to the mystery of what happened to the planet’s ancient atmosphere and how Mars has evolved over time.
Researchers analyzing pulverized rock onboard NASA’s Curiosity rover have found the largest organic compounds on the Red Planet to date. The finding, published Monday in the Proceedings of the National […]
Researchers have discovered two sets of ancient wave ripples on Mars, signatures of long-dried bodies of water preserved in the rock record. Wave ripples are small undulations in the sandy […]
![Along the Curiosity traverse [(A), gray line] through the Mirador formation, the rover observed symmetric ripple marks within the Prow outcrop near the base of Mirador butte at elevation −3950 m (B) and the Amapari Marker Band (AMB) outcrop along the west side of Marker Band Valley (MBV) at elevation −3860 m (C). Red stars indicate the locations of the ripple-containing outcrops within the stratigraphic column (D) along the MSL traverse (A). The Prow is one of the multiple lenticular outcrops within the Contigo member. The AMB outcrops are nearly continuously around MBV [(C): solid orange line], often forming flat, erosionally resistant benches (inner edge traced in dashed orange line). The basemap used in (A) to (C) is a Mars Reconnaissance Orbiter HiRISE mosaic generated by Calef et al.

Symmetrical wave ripples identified with NASA’s Curiosity rover in ancient lake deposits at Gale crater provide a key paleoclimate constraint for early Mars: At the time of ripple formation, climate […]
