Apollo 11 soil mechanics investigation.
The fine-grained surface material at the Apollo 11 landing site is a brownish, medium-gray, slightly cohesive granular soil, with bulky grains in the silt-to-fine-sand range, having a specific gravity of 3.1 and exhibiting adhesive characteristics. Within the upper few centimeters, the lunar soil has an average density of about 1.6 grams per cubic centimeter and is similar in appearance and beh...
متن کاملSpectrogoniometric Measurements And Modeling Of Apollo 11 Soil 10084
Introduction: Laboratory visible/near-infrared multispectral goniometer observations of Apollo 11 mature mare soil 10084 (splits 161, 2010, 2011) were acquired using the Bloomsburg University Goniometer (BUG) [1-4], with an emphasis on high phase angle observations. These data provided constraints on Hapke radiative transfer models for comparison to similar BUG data acquired of lunar analog soi...
متن کاملPotassium-uranium systematics of apollo 11 and apollo 12 lunar samples and of some deep Earth rocks.
theory that CNV and the P300 effect reflect the action of a common "activation" mechanism must be rejected. It is likely that all EEG activity is correlated with the gross arousal level of the subject and that this common element may introduce covariances between different phenomena derived from the EEG. But another process is required to explain the dissociability of CNV from the P300 effect. ...
متن کاملApollo 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...
