A Washington State University astrobiologist is leading a group of 20 scientists in calling for a mission to Mars with "a strong and comprehensive life detection component." At the heart of their proposal is a small fleet of sensor packages that can punch into the Martian soil and run a range of tests for signs of ancient or existing life.
They call the mission BOLD. It's both an acronym for Biological Oxidant and Life Detection and a nod to the proposal's chutzpah. The proposal, which comes as NASA is reevaluating its Mars exploration program, appears in the journal Planetary and Space Science.
"We really want to address the big questions on Mars and not fiddle around," says Dirk Schulze-Makuch, whose earlier proposals have included an economical one-way trip to the red planet. "With the money for space exploration drying up, we finally have to get some exciting results that not only the experts and scientists in the field are interested in but that the public is interested too."
The BOLD mission would feature six 130-pound probes that could be dropped to various locations. Shaped like inverted pyramids, they would parachute to the surface and thrust a soil sampler nearly a foot into the ground upon landing. On-board instrumentation would then conduct half a dozen experiments, transmitting data to an orbiter overhead.
