The Complete Book of Spaceflight: From Apollo 1 to Zero Gravity

470 visible light
visible light
Electromagnetic radiation that can be detected by the
human eye. It extends from a wavelength of about 780
nm (red light) to one of 380 nm (violet light), and bridges
the divide between infrared and ultraviolet.
VLS
An indigenous Brazilian four-stage, solid-propellant
launch vehicle capable of placing satellites weighing 100
to 380 kg into equatorial circular orbits 200 to 1,200 km
high. Configured as a missile, the VLS could fly 3,600 km
with a 500-kg nuclear payload. The first flight of the
19.2-m-long VLS ended in failure on November 2, 1997,
when it was destroyed 65 seconds into the flight following
a strap-on booster problem. In December 1999, a
second VLS had to be destroyed just three minutes into
its flight when the rocket again veered off course. There
have been no further launches.
Von Braun, Wernher Magnus Maximilian
(1912–1977)
One of the most important rocket developers and
champions of space exploration from the 1930s to the
1970s, and the son of a baron. Von Braun’s enthusiasm
for the possibilities of space travel was kindled early on
by reading the fiction of Jules Verne and H. G. Wells
and the technical writings of Hermann Oberth. It was
Oberth’s 1923 classic Die Rakete zu den Planetenräumen
(By Rocket to Space) that prompted the young von
Braun to master the calculus and trigonometry he needed
to understand the physics of rocketry. At age 17, he
became involved with the German rocket society, Verein
für Raumschiffarht (VfR), and in November 1932 he
signed a contract with the Reichswehr to conduct
research leading to the development of rockets as military
weapons. In this capacity, he worked for Captain
(later Major General) Walter Dornberger—an association
that would last for over a decade. In the same year,
under an army grant, von Braun enrolled at the
Friedrich-Wilhelm-Universität from which he graduated
two years later with a Ph.D. in physics; his dissertation
dealt with the theoretical and practical problems of
liquid-propellant rocket engines.
Some of von Braun’s colleagues from the VfR days
joined him in developing rockets for the German army
(see “A” series of World War II German rockets). By
1935, he and his team, now 80 strong, were regularly firing
liquid-fueled engines at Kummersdorf with great
success. Following the move to Peenemünde, von Braun
found himself in charge of the A-4/V-2 (see “V”
weapons) project. Less than a year after the first successful
A-4 launch and following a British bombing raid on
Peenemünde, mass production of the V-2 was switched to
an underground factory in central Germany. Von Braun
remained at Peenemünde to continue testing.
In mid-March 1944, von Braun was arrested by the
Gestapo and imprisoned in Stettin. The alleged crime was
that he had declared greater interest in developing the
V-2 for space travel than for use as a weapon. Also, since
von Braun was a pilot who regularly flew his governmentprovided
airplane, it was suggested that he was planning
to escape to the Allies with V-2 secrets. Only through the
personal intervention of Munitions and Armaments Minister
Albert Speer was von Braun released.
When, by the beginning of 1945, it became obvious to
von Braun that Germany was on the verge of defeat, he
began planning for the postwar era. Before the Allied
capture of the V-2 rocket complex, von Braun engineered
the surrender to the Americans of scores of his top rocket
scientists, along with plans and test vehicles. As part of a
military plan called Operation Paperclip, he and his
rocket team were whisked away from defeated Germany
and installed at Fort Bliss, Texas. There they worked on
rockets for the U.S. Army, launching them at White
Sands Proving Ground.
In 1950, von Braun’s team moved to the Redstone
Arsenal near Huntsville, Alabama, where they built the
army’s Jupiter ballistic missile. In 1960, his rocket development
center transferred from the army to the newly
established NASA and received a mandate to build the
giant Saturn rockets. Von Braun was appointed director
of the Marshall Space Flight Center and chief architect
of the Saturn V. He also became one of the most prominent
advocates of space exploration in the United States
during the 1950s. In 1970, he was invited to move to
Washington, D.C., to head NASA’s strategic planning
effort, but less than two years later, feeling that the U.S.
government was no longer sufficiently committed to
space exploration, he retired from the agency and joined
232, 305
Fairchild Industries of Germantown, Maryland.
Von Hoefft, Franz (1882–1954)
An Austrian rocket theorist who founded the first spacerelated
society in Western Europe. Von Hoefft studied
chemistry at the University of Technology, Vienna, the
University of Göttingen, and Vienna University, graduating
from the last in 1907. Subsequently, he worked as an
engineer in Donawitz, a tester at the Austrian Patent
Office, and a consultant. In 1926, he formed the Wissenschaftliche
Gesellschaft für Höhen-forschung (Scientific
Society for High Altitude Research) in Vienna and
later wrote a series of articles titled “The Conquest of
Space” for the Verein für Raumschiffarht’s publication,
Die Rakete (The Rocket), in which he laid out a remarkably
visionary scheme for the exploration of the Solar System
and beyond. The first step was the development of a
