In order to equalize the satellite skin temperatures and increase solar cell efficiency, an attempt is made to precess the satellite's spin vector perpendicular to the solar vector and maintain it in that position, using a magnetic torquing system that requires no commands from the ground. The advantage of this orientation to a high area thermal-mass ratio satellite with no batteries aboard is a temperature balance more favorable to power ...
Observations of thunderstorms in New Mexico were made with a vertically-scanning, 3 cm radar on a mountain-top. Prior to a lightning stroke the radar echo was usually quite weak indicating precipitation echoes of 5 mm/hr or less. Following the lightning stroke it was observed that in the region of the cloud where the stroke took place the radar echo intensity rapidly increased and a gush of rain or hail fell ...
