Space Rocket History #14 – US Space 1958 – Explorer, Vanguard, Pioneer, and NASA

Posted on May 30, 2013 by spac9750

In late March, 1958, President Eisenhower publicly announced the United States’ intention to launch a spacecraft to the Moon. He assured the nation that this was not science fiction. It was an achievable goal presented by leading scientists. The announcement came less than 2 months after the first US satellite had reached orbit. The President was committing the nation to a space race to the moon with the Soviets. If all went well the country would have a spacecraft in orbit around the moon before the summer was over.

At approximately 12:48 a.m. EST, the first listening stations began reporting that they had received radio signals from the “Explorer” satellite. The first station to confirm the signals was the San Gabriel Valley Amateur Radio Club near Pasadena, California. However, ABMA officials were waiting for confirmation from the Goldstone radio tracking station in Earthquake Valley, California. Finally, 1 hour and 57 minutes after launch the confirmation was finally relayed to ABMA officials in the form of the simple phrase, “Goldstone has the bird!”

On October 4th 1957, the Soviet Union demonstrated that it had to be taken seriously. Only a few years prior they had lagged the US badly in both bombers and Nuclear weapons. Now, there was deep concern that the Soviet’s could launch a nuclear attack on the US with their new R-7 ICBM. To add fuel to the fire, Just 4 days after Sputnik launched the Soviet Union detonated a 20 megaton Hydrogen bomb.

“The success of the Russian Sputnik was convincing and dramatic proof to people around the world of the real prospects of space travel in the not too distant future. The fact that a 23-in. sphere weighing 184 lb has been placed in an almost precise circular orbit indicates that a number of important technological problems such as high thrust rocket engines, lightweight missile structures, accurate guidance, stable autopilot control, and large scale launching methods have been solved, at least to the degree required for a satellite project.” Astronautics, Nov 1957.

By the late 1940’s, it became obvious that Army ballistic missile research activities required more room than what was available at Fort Bliss, Texas. After a long and through search the decision was made to move to the Redstone arsenal at Huntsville, Alabama. A farm town know for watercress, cotton and mosquitoes. The Redstone Arsenal was chosen for several reasons: it was on a large tract of government property, its location on the Tennessee River gave it access to the electrical power of the Tennessee Valley Authority, the climate was good, and it was not too far from Cape Canaveral, whose long range proving ground was growing in importance.
