Seeking Mars Architects

In line with NASA’s recent focus on Humans-to-Mars, the agency announced a new contest to design structures on Mars using existing materials found on the planet.  The In Situ Resource Utilization Challenge  offers a $10,000 first place prize and two $2,500 second place prizes.

Of course, ISRU is a cornerstone of all practical Humans-to-Mars proposals, and it’s nice to see NASA embracing it.  Personally I’d like to see a near-term sample return mission with the return powered by fuel derived form the Martian atmosphere, a much bolder ISRU demonstration than some of the proposals currently under consideration for the Mars 2020 mission.

ISRU is so critical because it significantly lowers the cost and (if done properly) the risk of the mission.  As NASA indicates:

One advantage of using resources from the planet instead of bringing everything from Earth is the potential to save the agency more than $100,000 per 2.2 pounds (1 kilogram) of cargo each launch.

As for that $100,000, that’s gotta come down quite a bit, regardless of ISRU.  Of course the private sector is making great strides there already.
