An analysis of new rock samples taken from NASA’s Curiosity rover uncovered evidence of clay minerals on Mars, suggesting the presence of water from a large, ancient lake. While the presence of clay supports the notion Mars may have once had water, it doesn’t conclusively prove the planet harboured conditions for life.

This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit: NASA/GSFC/USGS.
After revisiting decades-old data from the Voyager 2 flyby in Jan 1986, NASA scientists have found a shocking discovery. The analysis has revealed a “zigzag” in the magnetic data, just lasting one minute in the Voyager 2’s 45-hour flyby. The zigzag was previously not detected as the data was not analyzed in detail, and just looked at as an overview. Scientists believe that the zigzag represents a plasmoid, a type of structure that was not well understood in 1986.
