Explorer 1

Post by Christopher K. » January 8th, 2013, 1:03 pm

One of the hottest stretches of the Classic Space Race (I believe that although many do not perceive it, we're in another at this time) was those heady yet stressful days of the late 1950s. The U.S. and the Soviet Union were rushing to see who would or could claim atmospheric domination. Though Sputnik gave us pause--and a chill--and the Vanguard fiasco humbled us, we finally made it on 31 January 1958 with help from a Jupiter C rocket constructed under the supervision of Wernher von Braun.

The standout feature onboard Explorer 1 was the cosmic ray detector designed by James van Allen of the University of Iowa. A much lower count of cosmic rays than expected led van Allen to speculate on the possibility of a belt of charged particles encircling the Earth. In fact, there are two and they are now known as the Van Allen Belts.

It has been five years since the Forum first announced an anniversary for Explorer. Now this is a big one...happy sixtieth anniversary to the agency and the country who put up the Explorer 1 mission...
