TOP TECHNICAL CHALLENGES

The panel identified six top technical challenges for TA12. These are described briefly below in priority order. While not inconsistent with those identified in the NASA roadmap document itself, they differ in that there was no attempt to explicitly include challenges in each of the level 2 areas represented; that is: materials, structures, mechanical systems, manufacturing, and crosscutting.

1 Multifunctional Structures. Conceive and develop multifunctional structures, including shielding, to enable new mission capabilities such as long-duration human spaceflight, and to reduce mass.

Structures carry load and maintain shape. To the extent that a structure can simultaneously perform additional functions, especially those that would normally require add-on systems, mission capability can be increased with decreased mass. Integral shielding to reduce radiation exposure and micrometeoroid and orbital debris (MMOD) risk for human spaceflight missions would be game-changing, and the ISS would be useful to verify such concepts. Other advanced multifunctional structures concepts would enable structures, including joints, to provide thermal protection and control, electrical signal and power transmission, electrical energy and fuel storage, self-sensing
