Oxygen recovery systems for manned space flight.
T H E PROBLEM of supplying man with his oxygen requirement and uncontaminated air during prolonged confinement is receiving considerable research attention. In particular, the recovery of oxygen using biological specimens as the mechanism for converting carbon dioxide into oxygen plus other materials has been the subject of many papers recently. There can be no doubt concerning the need for a r...
متن کاملRadiation Hazards and Manned Space Flight.
T HE POTENTIAL medical hazards of man's venture into space will span a number of disciplines in regard to the pathology and deranged physiology to which the human body may be subject in travel beyond the earth's atmosphere. Not the least hazard is that having to do with the effects of radiation to be encountered in free space. This problem is one which is receiving considerable attention from a...
متن کاملPTTI-Aided Ephemeris Calculation and Rapid Data Link Acquisition for Manned Space Flight
Complexity of future manned space flight mission conlrol can be significantly reduced by integrating GPS, the PTTl source, into telemetry, tracking and command (TT&C). Future telecommunications, space tracking electronic intelligence, metrology, navigation, and data acquisition will thereby be sewed, including: I) On-board ephemeris determination, 2) Reduced synchronization time for time divisi...
متن کاملA review of available information on the acoustical and vibrational aspects of manned space flight.
T H I S P A P E R is a review of the problem of noise and vibration with respect to manned space flight. For the purposes of this discussion, noise will be defined as the energy transmitted to a man through the air at all frequencies up to 15,000 cps. Vibration will be defined as all of the energy transmitted to a man through the structural components for all frequencies above 0.5 cps. The sepa...
متن کاملThe Challenge of Evolving Mission Operations Tools for Manned Space Flight
In this paper we describe the impact of changing mission operations requirements on mission planning tools for human spaceflight. We use the task of planning S-Band communications for the International Space Station (ISS), as a case study. Existing planners such as the Consolidated Planning System (CPS) permit the declaration of requirements for activities, such as the set of allowed S-Band com...
