Inflatable Heat Shield -- Nasa Seeks Game Changing Designs for Mars

Inflatable Heat Shield Technology NASA's Next BIG Idea Challenge

NASA is giving university and college students an opportunity to be part of the agency's journey to Mars with the Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge.

Inflatable Heat Shield

NASA's Game Changing Development Program (GCD), managed by the agency's Space Technology Mission Directorate in Washington, and the National Institute of Aerospace (NIA) are seeking innovative ideas for generating lift using  an inflatable heat shield or hypersonic inflatable aerodynamic decelerator (HIAD) technology.  

Steve Gaddis, GCD Manager at NASA's Langley Research Center in Hampton, Virginia, said:

NASA is currently developing and flight testing HIADs - a new class of relatively lightweight deployable aeroshells that could safely deliver more than 22 tons to the surface of Mars.  A crewed spacecraft landing on Mars would weigh between 15 and 30 tons.

The NASA's Mars Curiosity rover is the heaviest payload ever landed on the Red Planet - weighing in at only one ton. To slow a vehicle carrying a significantly heavier payload through the thin Martian atmosphere and safely land it on the surface is a significant challenge.

NASA is addressing this challenge through the development of large aeroshells that can provide enough aerodynamic drag to decelerate and deliver larger payloads -- in words, an inflatable hear shield. HIAD technology is a leading idea because these kinds of aeroshells can also generate lift, which would allow the agency to potentially do different kinds of missions.

Teams of three to five undergraduate and/or graduate students interested in developing inflatable heat shield technology are asked to submit white papers describing their concepts by Nov. 15. Concepts may employ new approaches such as shape morphing and pneumatic actuation to dynamically alter the HIAD inflatable structure.

Selected teams will continue in the competition by submitting in the spring of 2016 full technical papers on the concept. Up to four teams will present their concepts to a panel of NASA judges at the BIG Idea Forum at Langley in April 2016.

Each finalist team will receive a $6,000 stipend to assist with full participation in the forum. BIG Idea Challenge winners will receive offers of paid internships with the GCD team at Langley, where they can potentially work toward a flight test of their concept.
