NASA experiment suggests need to dig deep for evidence of life on Mars

According to a new NASA laboratory experiment, rovers may need to dig 6.6 feet (two metres) or more beneath the Martian surface to find evidence of ancient life because ionising radiation from space degrades small molecules like amino acids relatively quickly. Life and non-biological chemistry...

Mars Reconnaissance Orbiter releasing one of its last rainbow-colored maps

A multicoloured 5.6-gigapixel map of Mars is about to provide scientists with a new perspective on the planet. The map, which covers 86 percent of Mars' surface, reveals the distribution of dozens of key minerals. Scientists can better understand Mars' watery past and prioritise...

NASA announces Artemis concept awards for nuclear power on moon

NASA and the United States Department of Energy (DOE) are collaborating to advance space nuclear technologies. The agencies have chosen three design concept proposals for a fission surface power system that could be ready for launch by the end of the decade for a...

A long history of flowing water recorded in clay-bearing sediments on Mars

According to a new paper by Planetary Science Institute Senior Scientist Catherine Weitz, a region on Mars may have been repeatedly habitable until relatively late in Martian history. The Margaritifer Terra region, where deposits of clay-bearing sediments have been identified, contains some of the most...

NASA’s InSight gets a few extra weeks of Mars science

The mission's team has decided to keep the seismometer running for longer than planned, despite the fact that the lander will run out of power sooner as a result.As the power available to NASA's InSight Mars lander diminishes by the day, the mission's timeline...

Martian meteorite upsets planet formation theory

A new study of an ancient meteorite challenges current theories about how rocky planets like Earth and Mars acquire volatile elements like hydrogen, carbon, oxygen, nitrogen, and noble gases as they form. The study was published in Science on June 16th. According to Sandrine...
