White Sands
White Sands
It was the U.S. Army's White Sands Missile Range in New Mexico, where rocket test flights continued after World War II.
The V-2 rocket |
The
Army brought the V-2 missile parts captured in Germany for its Project
Hermes missile development program, managed by General Electric. Wernher
von Braun and his team were housed at nearby Fort Bliss, Texas.
From the spring of 1946 up to the fall of 1952, 67 V-2 rockets were launched. The use of these rockets launched the United States into the Space Age in the end. Post-war American liquid fueled rocket engines built later evolved directly from the German engine that powered the V-2. In 1953 the first Redstone rocket was launched for the Army. Around 1950 the Army's missile program was tranferred to a place outside Huntsville, Alabama, launch operations moved to Cape Canaveral in Florida. The Cold War between the U.S. and the U.S.S.R. provided the necessary financial background, not for going into space but for work on intercontinental strategic missiles. Wenher von Braun had to learn this in a conversation with President Dwight D. Eisenhower in the mid-fifties. |
The Viking rocket |
Competing Forces
The Navy's Viking program followed the V-2 experiments. The Naval Research
Laboratory's Project Vanguard was to be based upon that rocket and available
upper stages (four stages in all) in 1955.
The Vanguard program was only trying to launch one and only one
satellite for scientific purposes.. They also wanted to conduct one
experiment successfully sometime during the International Geophysical Year
(the 18-month "year" from January 1957 to July 1958). It was in the times
of the Cold War and Vanguard wasn't given the least military priority.
The Vanguard team had to struggle and fight for money, range time at the
Cape, any kind of support in any way.
The entire program was planned for 14 launch vehicles, not all of those
"satellite launch vehicles."
The Air Force proposed a combination called World Series based on an Atlas carrying as its upper stage the well proven Aerobee-Hi space probe rocket.
The Army proposed Project Orbiter (which had been a joint submission
with the Navy first), using the Redstone missile plus upper stages
of Loki rockets.
The Army Ballistic Missile Agency incorporated the Von Braun team in
key positions with Dr. Von Braun as head of the Development Operations
Division.
A decision in favor of the Vanguard program was made in 1955 in the month of August. President Eisenhower had made up his mind not to let scientists use a military intercontinental rocket. Even though the Air Force space effort, considered as a back-up system, was on a sound technical foundation, Pentagon officials didn't like it and adequate funding was lacking.
On October 4, 1957, the nation was shocked when the Russians launched
Sputnik, the world's first artificial satellite. Two months later, the
United States suffered disappointment when a Navy Vanguard rocket,
with its satellite payload, failed to develop enough thrust, thus toppled
over on the launch pad.
 |
Due to their foresight in planning and preparation, the Von Braun team
with the Army Ballistic Missile Agency was ready when the United States
turned to the Huntsville group to launch America's first satellite in a
couple of weeks. In January 1958, a modified Redstone rocket named Jupiter-C
carried America's first satellite Explorer I into orbit.
It was not before the Navy's Vanguard 2, had a successful launch. |
NASA
 |
On October 1, 1958 NASA - the National Aeronautics and Space Administration - began operations as the successor to NACA - the National Advisory Committee for Aeronautics. It owned three major research laboratories - Langley Aeronautical Laboratory, Ames Aeronautical Laboratory, and Lewis Flight Propulsion Laboratory - and two smaller test facilities. |

Project Mercury started on October 7, 1958. Its goal was to send an
astronaut into space in a space capsule that would protect him from the
temperature extremes, vacuum and the recently discovered radiation belts
around the planet. Also had it to keep an astronaut cool during the flaming
high-speed reentry phase into the atmosphere on its way back. Thus it had
to have an ablative heat shield that burned off as Mercury returned to
Earth.
Mercury capsules rode into space on two different kinds of booster.
The first suborbital flights were launched on Redstone rockets designed
by Wernher von Braun's team. For orbital flights, the Mercury capsule was
placed on top of an Atlas-D, a modified ballistic missile whose steel skin
was so thin (in order to save weight) it would have collapsed like a bag
if not pressurized from within.

There were six Mercury flights. The first manned flight took place on May 5, 1961. It was astronaut Alan B. Shepard, Jr.whose Freedom 7 Mercury spacecraft was launched to an altitude of 115 nautical miles and a range of 302 miles in a fifteen-minute suborbital flight. Shepard was the second human and the first American to fly in space after Soviet cosmonaut Yuri Gagarin who had circled the Earth once on April 12, 1961. |
 |
On February 20, 1962, Astronaut John H. Glenn became the first American to circle the Earth, making three orbits in his Friendship 7 Mercury spacecraft. |
Gemini
The Gemini project was announced to the public on January 3,
l962, Apollo being well underway already. Its primary goal was to
demonstrate space rendezvous and docking-techniques that would be used
during Apollo. Gemini also was to extend astronauts' stays in space to
up to two weeks, thus making space flight to become routine.
Ten piloted missions left the launch pads of Cape Canaveral, Florida,
in less than 20 months in 1965 and 1966 after unmanned testing in 1964.
The Manned Spacecraft Center (renamed the Johnson Space Center
in 1973) outside Houston, Texas, took over the role of Mission Control.
Gemini rode into orbit on a Titan 2 launch vehicle. The target
for rendezvous operations was an unmanned Agena upper stage, which
was launched ahead of the Gemini.
 |
Gemini weighed more than 3,628.72 kilograms-twice the weight of Mercury-but
having only 50 percent more cabin space for two people.
The capsule needed real maneuvering capability to rendezvous with another spacecraft, moving forward, backward and sideways in its orbital path, even changing orbits. Thus two people were needed on board. It also required the first onboard computers to calculate those complicated rendezvous maneuvers. The second piloted Gemini mission, Gemini IV, lasted for four days, June 3-June7,1965, and astronaut Edward H. White II performed the first spacewalk by an American. |
