Sixty years ago this week, Florida's
"Space Coast"
was born with the launch of a rocket called Bumper 8 on July 24, 1960,
from
what was then called Long Range Proving Ground Base on Cape Canaveral.
Today, Cape Canaveral is America's gateway to the universe, but it wasn't
the first
place from which rockets were launched in the United States.
After World War II, when military
rocket technology was in
its infancy, rockets were launched from White Sands Test Facility in
New
Mexico. But the technology was, literally, outgrowing the test range
there.
"The total length of range at White
Sands was about 100
miles," said Stan Starr, chief of the Applied Physics Branch at Kennedy
Space Center. "Everything they launched had to go straight up, and
slightly to the north so the radar and telemetry stations would be able
to see
the rockets to track them."
But to achieve great distances — and
there were a number of
military programs at the time had exactly that goal — they need a long
range
and the ability to track the rocket throughout the range, Starr said. Should something go wrong, rocket engineers also wanted to be sure
that rockets
would land benignly, preferably in an ocean.
"The Cape had a big advantage," Starr
said over
other locations. It was selected for two reasons: the fact that it is
relatively near to the equator compared to other U.S. locations, and
the fact
that it is on the East Coast.
An East Coast location was desirable
because any rockets leaving Earth's surface and traveling eastward get a boost from the
Earth's spin. A
West Coast location would either send rockets over populated areas or
have to contend
with launching against the direction of the spin.
"Any object on the Earth's surface is
already moving
east very fast," Starr said.
And, the rate of spin is at its
highest on the equator and
slowest at the poles, so the Cape's southern location also gave it a
boost,
Starr said. Cape Canaveral is about 28 degrees latitude above the
equator.
The Bumper rocketsthat
were tested in 1950 were the first two-stage rockets to be developed,
Starr
said. Two-stage rockets involve one rocket that launches from the
ground, and a
second rocket that launches from the first in flight, during a
separation.
There were eight Bumper rockets in
total, and the first six
were launched from White Sands. But Bumper 5 soared to an altitude of
244
miles, which is higher than the International Space Station orbiting the Earth today, and heightened the
need to find a
larger launching range, Starr said.
The Air Force installation on Cape
Canaveral was renamed
Patrick Air Force Base on Aug.1 1950.
Today, the Base is adjacent to the
Kennedy Space Center, and
in the years since the Bumper rockets, Cape Canaveral hosted more than
3,000
rocket launches.
