Space Rocket History #12 – Vanguard TV3 – Flopnik

“It seemed as if the gates of hell had opened up. Brilliant stiletto flames shot out from the side of the rocket near the engine. The vehicle agonizingly hesitated for a moment, quivered again, and in front of our unbelieving eyes, began to topple. It sank like a great flaming sword down into the blast tube it toppled slowly breaking apart, hitting part of the test guard and ground with a tremendous roar that could be felt and heard even behind the 2 food concrete wall of the blockhouse. For a moment or two there was complete disbelief. I could see it in the faces. I could feel it myself.”

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.

It’s important to understand that in the late 1940s within the United States there were three concurrent programs for military rocket development. This was due to continuing inter-service rivalry between the Army, Navy, and Air Force.
