Scientists Search for Ancient Fossils in Australia, Practicing the Techniques They’ll Use on Mars

NASA’s Mars 2020 Rover is heading to Mars soon to look for fossils. The ESA/Roscosmos ExoMars rover is heading to Mars in the same time-frame to carry out its own investigations into Martian habitability. To meet their mission objectives, the scientists working the missions will need to look at a lot of rocks and uncover and understand the clues those rocks hold.

To help those scientists prepare for the daunting task of analyzing and understanding Martian rocks from 160 million km (100 million miles) away, they’ve gone on a field trip to Australia to study stromatolites.

This is Where Mars 2020 Rover is Heading. From this Picture, I Think You Can Guess Why

Get used to hearing the name “Jezero Crater.” It’s the landing site for NASA’s Mars 2020 rover. The 2020 rover is slated to launch in July 2020, and will land at Jezero Crater in February, 2021.

It’s pretty easy to see why NASA chose Jezero Crater for the next rover in their Mars Exploration Program (MEP). MEP is NASA’s long-term plan to explore Mars robotically. It includes rovers like Spirit, Opportunity, and MSL, the InSight Lander, orbiting spacecraft, and soon the 2020 rover.

Curiosity has Finally Sampled a Clay-Rich Region on Mars

It’s hard to believe that MSL Curiosity has been on Mars for almost seven years. But it has, and during that time, the rover has explored Gale Crater and Mt. Sharp, the central peak inside the crater. And while it has used its drill multiple times to take rock samples, this is the first sample it’s gathered from the so-called ‘clay unit.’
