NASA’s Perseverance rover is on course to land on Mars next week. An artist’s impression shows its target – Jezero Crater – as it might have appeared in the distant past.
Stratigraphy in Gale Crater on Mars indicates the effects of megafloods in the distant past, most likely caused by the heat released in a major impact.
An experimental helicopter has been attached to NASA’s Mars 2020 rover, a pathfinder that could pave the way for more advanced aircraft on future missions.
A rover NASA plans to launch to Mars in 2020 will likely explore one of three locations selected last week by a scientific advisory group, which picked candidate landing sites that were once homes to ancient lakes and hot springs.
