Self-* Properties in NASA Missions
The four key objective properties of a system that are required for it to qualify as “autonomic” are now wellaccepted––self-configuring, self-healing, self-protecting, and self-optimizing––together with the attribute properties––viz. self-aware, environment-aware, selfmonitoring and self-adjusting. This paper describes these self-* properties as exhibited in NASA missions, and in particular wit...
متن کاملModular Growth NTR Space Transportation System for Future NASA Human Lunar, NEA and Mars Exploration Missions
The nuclear thermal rocket (NTR) is a proven, high thrust propulsion technology that has twice the specific impulse (Isp ~900 s) of today’s best chemical rockets. During the Rover and NERVA (Nuclear Engine for Rocket Vehicle Applications) programs, twenty rocket reactors were designed, built and ground tested. These tests demonstrated: (1) a wide range of thrust; (2) high temperature carbide-ba...

To compare working methodologies between the cost engineering functions in NASA Marshall Space Flight Center (MSFC) and ESA European Space Research and Technology Centre (ESTEC), as well as to set-up cost cngi~iccri~~g ciipbiiiiies fur future manned Mars projects and other studies which involve similar subsystem technologies in MSFC and ESTEC, a demonstration cost estimate exercise was organize...
متن کاملArmchair Missions to Mars
Computer simulation of long missions in space can provide experience and predictions without the expense and risk of actual flights. Simulations are most helpful if they can model the behavior of key psychological factors of the crew over time, rather than simply predicting overall mission success. Because of the lack of experience with interplanetary trips and the problems of generalizing and ...
متن کاملExobiology and Future Mars Missions
Nitrogen is an essential element for the evolution of life as we know it, because it is found in avariety of biologically important molecules. Therefore, N is an important element to study from anexobiological perspective. In particular, “fixed nitrogen” is the biologically useful form of nitrogen.Fixed nitrogen is generally defined as “3, NH;, NO,, or N that is chemically bound to ...
