Color-discerning capabilities that NASA’s Curiosity rover has been using on Mars since 2012 are proving particularly helpful on a mountainside ridge the rover is now climbing.
And there are indications that groundwater persisted for far longer.
Curiosity rover findings add to a puzzle about ancient Mars because the same rocks that indicate a lake was present also indicate there was very little carbon dioxide in the air to help keep a lake unfrozen.
Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet’s surface.
The layered geologic past of Mars is revealed in stunning detail in new color images returned by NASA’s Curiosity Mars rover, which is currently exploring the “Murray Buttes” region of lower Mount Sharp. The new images arguably rival photos taken in U.S. National Parks.
New data suggest Mars was habitable for perhaps hundreds of millions of years
More study is needed to determine where the organics came from and how they managed to survive in the Red Planet’s harsh environment.
NASA’s Mars rover Curiosity has halted its trek up a mountain filled with potentially habitable niches for life while engineers troubleshoot a problem with one of its key instruments, scientists said on Tuesday.
