responded by saying that the initial focus should be to reduce the biological uncertainty associated with the effects of the space radiation environment.

Session 8: Industry Panel

Paul Zamprelli (Orbital Technologies Corporation) started the session with a summary of the technology developments being conducted by ORBITEC. Pertaining to the technologies covered by TA06, Zamprelli discussed the company’s hybrid ECLSS resource recovery development. This system is being designed to demonstrate 90 percent oxygen and 98 percent water resource recovery closure compared to the 60 percent closure demonstrated by the ISS ECLSS. Currently, according to Zamprelli, the ORBITEC hybrid ECLSS has demonstrated approximately 84 percent closure at the time of the workshop.

Barry Finger (Paragon Space Development Corporation) provided an overview of the current state of the art of ECLSS on the ISS. He then identified the need for a simple, reliable, and maintainable ECLSS for long-duration human spaceflight beyond LEO. Finger then went on to identify the ISS as a necessary test bed for ECLSS technologies. Regarding the TA06 Roadmaps, he believes that ECLSS advancements are true game-changing technologies for deep space human missions.

Greg Gentry (Boeing) provided a series of lessons learned from developing and maintaining the ECLSS on both the space shuttle and the ISS. These lessons learned were extensive and ranged from general “philosophical” lessons learned to specific component-level lessons learned. His overall lesson learned was that when changes are made in operational systems, be ready to deal with “unintended consequences.”

Edward Hodgson (Hamilton Sundstrand) provided his assessment of the TA06 EVA roadmap. He identified several possible gaps in the roadmap such as “on-back” mass and volume reduction to support Mars surface missions. Additionally, Hodgson suggested that the roadmap assumes comparable EVA sortie durations to history; however, radiation environments could significantly change the EVA architecture due to lack of protection/shielding leading to insignificant EVA operations.
