Here are details about a : Space commemorative cover or Space Cover.

Cosmodrome / Location : USA
Date of Cancellation: July 11, 1968 Event Type : Launch Launch Pad / Location : USA Vandenberg SFB (CA) Manned / Robotic Mission : Robotic Mission Objective/Type : Experimental / Science
ou?/where?: au sol - ground
autographe?: non - noneDescription : Vandenberg post stamp and OV 15 &16 research satellites in polar orbit with Atlas Booster.
OV1-15, also referred to as SPADES (Solar Perturbation of Atmospheric Density Experimental Satellite), was designed to study synoptically the fluctuations of atmospheric density, composition, and temperature as a function of solar magnetospheric disturbances.
The principal active experiment was a triaxial accelerometer that measured satellite acceleration near perigee. Atmospheric densities were then computed from these data. The sphere also contained a c-band tracking beacon for drag density determination. Keyword(s) : #Rocket, #Satellite, This is OUTSIDE of a Space Revue. Last modified: 05/19/2009 @ 21h47
