As Martian spacecraft experience solar conjunction, Perseverance confirms Jezero Crater’s watery past
On October 2, 2021, all actively operating spacecraft at Mars ceased major communication with Earth as the planet entered its solar conjunction — an event wherein Mars crosses behind the Sun, limiting communication with Earth. As this began, NASA’s Perseverance rover’s science team released a new paper detailing the water-filled past of Jezero Crater —…

Analysis of Mars surface samples highlight potential ancient water bubbles
Following an unsuccessful sample collection attempt in early August, NASA’s Perseverance Mars rover has successfully drilled, collected, sealed, and stored two separate Martian surface samples. Both sample collections took place in the same week. Additionally, new data from the samples show that the rock collected is likely volcanic and may contain bubbles of ancient water.…

Mars Express water discovery reopens intriguing questions for future Martian Exploration
For the first time in human exploration of Mars, the presence of a stable, subterranean body of salty (briny) water has been strongly suggested by data returned by the European Space Agency’s Mars Express orbiter. Using measurements taken by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument, a team of Italian researches…

Rover data suggest Mars crater once contained long-lived lake
This illustration depicts a lake of water partially filling Mars’ Gale Crater, receiving runoff from snow melting on the crater’s northern rim.
