The Sample Analysis at Mars (SAM) tunable laser spectrometer onboard Curiosity last week detected surprisingly high levels of the gas methane at Gale Crater:...
Planetary scientists have long observed water-ice clouds in the Martian middle atmosphere (18.6-37.2 miles, or 30-60 km, above the surface). Now, a University...
Planetary researchers using data from the Shallow Radar (SHARAD) instrument on NASA’s Mars Reconnaissance Orbiter have discovered rich deposits of water...
According to new research, published in the journal Geology, processes not involved in controlling sand movement on Earth play major roles on the Red Planet,...
On April 24, 2019, NASA’s Mars Odyssey orbiter captured a new thermal image of Phobos, the larger of Mars’ two moons. Each color in the full-moon image...
In April 2019, NASA’s InSight lander used its Instrument Deployment Camera (IDC) to capture a series of Martian sunrise and sunset images.

The SEIS (Seismic Experiment for Interior Structure) instrument on NASA’s InSight lander detected the faint seismic signal on April 6, 2019, the lander’s...
NASA’s Mars rover Curiosity has captured several stunning videos of solar eclipses from the surface of the Red Planet.
Phobos transits the Sun’s disk,...
ALH-77005, a Martian rock found in Antarctica, contains numerous mineralized ‘biosignatures,’ including coccoidal, filamentous structures and organic...
The discovery of life on Mars would get pretty much everyone excited. But the scientists hunting for it would probably be happy no matter what the outcome...
Mars is dry today, but numerous ancient rivers are found across the planet’s surface and their existence is a challenge to models of planetary climate...
After eight months of effort and sending more than a thousand commands in an attempt to restore contact with the Mars rover Opportunity, NASA declared...
Future manned trips to Mars will require on-site resources, including water, and planetary scientists from a project called ‘Subsurface Water Ice Mapping...
Observations by ESA’s Mars Express orbiter show evidence of an ancient planet-wide groundwater system on the Red Planet.
Mosaic of the Valles Marineris...
Mars today is a cold, dry world, but it may not always have been so. Recent studies increasingly indicate that the planet once had a thicker, denser atmosphere...
Beginning Tuesday, February 19, 2019, NASA’s InSight lander will provide a daily report of atmospheric weather conditions on Mars. This tool, developed...
Recent radar observations from ESA’s Mars Express spacecraft were interpreted as evidence for melting beneath the south polar ice cap of Mars. Now, a...
New images from the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express spacecraft show an impact crater in the northern lowlands of Mars. Known...
