Description:
In the not too distant future, NASA may consider sending a robotic mission to Mars to drill tens of meters below the surface to search for evidence of life. Mars science groups, including NASA's Mars Exploration Program Analysis Group (MEPAG), have repeatedly concluded that in situ scientific analyses of samples from significant depths below the surface are important for understanding Mars in general and for searching for evidence of past or present life in particular. Furthermore, there are several ongoing technology developments for relevant drills, the readiness of which seem promising for use by the second decade of this century. By accessing and analyzing material from tens of meters below the surface, in situ science investigations may help answer some important questions about Mars, in particular about whether life ever existed there. Drilling is a proven technique for terrestrial applications that appears viable for accessing Martian subsurface samples and bringing them to the surface for analysis by a variety of instruments. An end-to-end mission concept for a Deep Drill mission has been developed and appears feasible for launch in the next decade.
