Apollo 14 and apollo 16 heavy-particle dosimetry experiments.
Doses of heavy particles at positions inside the command modules of Apollo missions 8, 12, 14, and 16 correlate well with the calculated effects of solar modulation of the primary cosmic radiation. Differences in doses at different stowage positions indicate that the redistribution of mass within the spacecraft could enhance safety from the biological damage that would otherwise be expected on ...
متن کاملApollo: god. . . and anesthetist?
A OCCIDENTALS, we are the heirs of Ancient Greek civilization. Given that the practice of anesthesia is considered less than 200 yr old, it seems hard to believe that the unusual idea of putting someone to sleep during a painful medical procedure was actively discussed and intricately imagined more than 25 centuries ago. Yet the Greek myths tell us of a Homeric warrior named Philoctetes who was...
متن کاملAnother Look at the Summit Caldera of Apollinaris Patera
Introduction: Highland paterae [1-2] represent one of the most distinctive landforms on the Martian surface. The term patera (paterae if plural) was originally applied to any large, flat-floored depression with irregular margins identified in Mariner 9 and Viking imagery and included volcanoes as well as impact craters [3]. However, highland paterae represent an individual class of patera that ...
متن کاملGuide to the Apollo Collection
The Saturn C-1 Heavy space vehicle will be launched experimentally this fall for the first time. In this first firing of the three stage rocket, only the booster will be "live" and it will be operating at a thrust somewhat lower (12%) than that planned for later Saturns Series 5 High Water Project
متن کاملThe Bidirectional Reflectance of Apollo
Introduction: Accurate models of the lunar thermal and illumination environment require a realistic treatment of scattered radiation at high incidence and emission angles. It has long been appreciated that the bidirectional reflectance of lunar soil is anisotropic [1], yet most lunar thermal models still assume that scattered radiation is isotropic. We recently measured the bidirectional reflec...
