US space science: Manned flight to Mars?

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...

Radiation 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...

Concept for Manned Missions to Mars

In a previous paper, a new scenario for human missions to Mars has been presented. It can be named the 2-4-2 concept. The idea is to minimize IMLEO and the payload on Mars with a crew of only two astronauts. There are two astronauts in each rocket at departure from Earth. They meet on Mars to form a team of four and the pairs are reconstituted for the return (2-4-2). In the previous study it wa...

PTTI-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...
