Space Life Support

Life support for first manned spaceflights was based on supplies of consumables. Crew life support systems based on supplies of water and oxygen, in spite of their simplicity, are extremely inefficient in orbital space missions and are unfeasible in deep space missions because of mass and volume constraints. Therefore, there are currently developed and are to be used on space stations the life support systems that are based on chemical and physical regeneration of water and oxygen extracted from human waste. In view of further advances in long-duration orbital stations, and the prospects of establishment of planetary outposts and deep space exploration, the problem of constructing an automated system for controlling a suite of regenerative LSS becomes urgent. The complexity of solving the problem of constructing an efficient control system in this case owes to the existence of a large number of effectiveness criteria. The paper proposes a system of consolidated global efficiency criteria, which allows to break up this problem into a series of sub-problems of optimization in order to solve this problem. The proposed criteria are longevity, cost, comfort. The paper presents a series of specific examples of using the proposed principles with necessary generalizations. Key words: space life support systems, atmosphere revitalization equipment, automated control system, global generalized efficiency criteria, longevity, cost, comfort.

The Army's acquisition process is transforming to meet the needs of a force that must be agile, adaptive, and responsive to asymmetric threats. Advanced capabilities and technologies, which are urgently needed to enable rapid response to evolving military needs, are being developed and pushed out to troops at unprecedented rates. As a result, not all systems have undergone an iterative design process, received usability feedback from their target users, or had design support from human factors engineers to ensure that unit and Soldier considerations have been addressed. Subsequently, these systems may possess characteristics that induce high cognitive workload, fatigue, detectability, or trigger events that lead to fratricide. When human factors engineers encounter a system that has not derived these benefits, they too must become more agile, adaptive, and responsive to ensure that Soldier feedback is collected and that serious issues are identified and resolved before the system makes its way to the battlefield. Lessons learned while participating in advanced technology and experimentation programs include techniques that facilitate working with small Ns, institutional review boards, rapid survey instrument development, and the collection of qualitative feedback as well as the importance of having a “usability tool kit” available to facilitate data collection efforts in an operational field environment.
