Mars: November 2019


As any geologist worth his or her salt will tell you, there are rocks, and then there are rocks. Next July, NASA and the European Space Agency (ESA) are launching rovers to Mars that will search for signs of past microbial life, and to find them, the scientists with NASA's Mars 2020 mission and ESA's ExoMars will need to examine different kinds of rocks that lend compelling insights into the environment in which they were made -- all from 100 million miles away.

Scientists with NASA's Mars 2020 rover have discovered what may be one of the best places to look for signs of ancient life in Jezero Crater, where the rover will land on Feb. 18, 2021.

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars.

Next year, NASA plans to launch a new Mars rover to search for signs of ancient life on the Red Planet.

The escape of hot O and C atoms from the present martian atmosphere during low and high solar activity conditions has been studied with a Monte-Carlo model.

Researchers have provided new calibrations for the humidity sensor on NASA's Phoenix lander on Mars (the Phoenix Thermal and Electrical Conductivity Probe (TECP) relative humidity sensor).
