Will we kill (or contaminate) microbial life on Mars?

“This has implications for plans for sample return from Mars and for future human missions.” --- NASA astrobiologist Chris McKay, PhD

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. (credits: NASA/JPL/University of Arizona)

Bendable electronic color ‘paper’ invented
