THE PRIZES
Total prize pool of US$15,000 available in the form of:
•One First Place Prize of US$10,000
•Two Second Place Prizes of US$2,500
NASA will recognize prizewinners through published announcements and
individual profile stories. Successful applicants may also have the
opportunity for future collaboration with NASA.
ABOUT THE CHALLENGE
Transforming in situ materials such as regolith or basalt into useful
structural elements is a significant way to reduce the mass of materials
launched as payload from Earth. Considering exploration on Mars, for every
kilogram of native materials used, one saves 11 kg of transportation
propellant and spacecraft mass required to launch to Low Earth Orbit (LEO).
Given the cost for LEO is US$10,000/kg, one avoids at least US$110,000/kg
of cost by using 1 kg of in situ materials, making space pioneering on Mars
more affordable and feasible.
One could use surface-based materials such as regolith or basalt to produce
structural elements that can be interconnected to create launch/landing pads
; blast protection berms; roads and walkways; radiation, thermal, and micro-
meteorite shielding insulation and structures; equipment shelters; pressure
vessels for fluids storage; ablative atmospheric entry heat shields;
construction foundations; and other useful structures. | u****q
