...earth's first man-made satellite is nearing the end of the planning stage. Last week the National Academy of Sciences released information about the small, short-lived artificial moon that will be shot into an orbit during the International Geophysical Year (1957-58). The launching vehicle will be a three-stage rocket. The first stage, whose rocket motor will have 27,000 lbs. of thrust, will take off from the Air Force's missile test base at Cape Canaveral, Fla. About two minutes after takeoff, it will have traveled about 40 miles, and will be traveling...
...orbit selected for the satellite is 40° from the equator, and the rocket will be fired toward the southeast to take advantage of the earth's rotation. Instead of following a true circle, which would keep it at a single level in the earth's high atmosphere, the satellite will move in an ellipse (oval), rising to 800 miles altitude, then descending to 200 miles. It will pass around the earth every 90 minutes, and since the earth will be turning beneath it, the satellite will pass over different areas during each circuit. It will eventually cover...
...density. The satellite's rate of slowdown and change of orbit will yield information about the high atmosphere...
...Crust of the earth. Variations in the earth's gravitational pull will distort the orbit slightly. Thus irregularities in the earth's crust and the slight bulge at the earth's equator can be determined more accurately...
Before departing for the satellite orbit, Tenley will participate in the German competition at Garmisch-Partenkirchen. After her trip to Czechoslovakia and Poland, she plans to give exhibitions in Vienna, Helsinki, Berlin, Paris, and London before starting home...
