Long-Lived Mars Rover Opportunity Keeps Finding Surprises

NASA's Mars Exploration Rover Opportunity keeps providing surprises about the Red Planet, most recently with observations of possible "rock stripes."The ground texture seen in recent images from the rover resembles a smudged version of very distinctive stone stripes on some mountain slopes on Earth that result from repeated cycles of freezing and thawing of wet soil. But it might also be due to wind, downhill transport, other processes or a combination.

This is not the first time that Marshall and his co-authors have advocated using vanadium to search for signs of life. Such was the subject of a presentation they made at the Astrobiology Science Conference in 2015. What’s more, Marshall and his team emphasize that it would be possible to perform this technique using instruments that are already part of NASA’s Mars 2020 mission.

When it comes time to explore Mars with crewed missions, a number of challenges will present themselves. Aside from the dangers that come with long-duration missions to distant bodies, there’s also the issue of the hazards presented by the Martian landscape. It’s desiccated ans cold, it gets exposed to a lot of radiation, and its pretty rugged to boot! So astronauts will need a way to get around and conduct research in comfort and safety.

WOW, mars sure can be pretty

For a supposedly dead world, Mars sure provides a lot of eye candy. The High Resolution Imaging Science Experiment (HiRise) aboard NASA’s Mars Reconnaissance Orbiter (MRO) is our candy store for stunning images of Mars. Recently, HiRise gave us this stunning image (above) of colorful, layered bedrock on the surface of Mars. Notice the dunes in the center. The colors are enhanced, which makes the images more useful scientifically, but it’s still amazing.
