The Space Race
In
the 1950's and 1960's, the USA and the Soviet Union raced each
other to be first into space. The Soviet Union won.
On 4 October 1957, the Soviets launched Sputnik 1, the
first spacecraft to circle the world in space orbit. Then on 12
April 1961. Soviet astronaut Yuri Gagarin
became the first man to fly in space.
The 'space race' was one of tragedy and triumph, from the time
the Russians catapulted the heroic Gagarin and his Vostok
("East") spacecraft into orbit for 108 minutes (although
the Sputnik 2 satellite, launched in 1957, carried the
first traveller in space - a Russian dog called Laika).
Less than a month later, on 5 May 1961, Alan Shepard captivated
US television audiences when he became the first American
astronaut in space aboard Liberty Bell 7.
Capitalising on space exploration as a propaganda tool, President
Kennedy committed $9 billion to sending the first man to the
moon before the end of the decade.
On 20 February 1962 the US found a new space hero in John
Glenn, who became the first American in orbit. In 4 hours 55
minutes he orbited the earth three times aboard Friendship 7.
On his return, New Yorkers took to the streets in welcome as he
was paraded through the city under a deluge of ticker tape. 36
years later, Glenn returned to space as part of a study on the
human body and the ageing process.
Valentina Tereshkova became the first woman to travel into
space on 16 June 1963. She made 49 orbits of the Earth in the Vostok
6 spacecraft before landing in the Soviet republic of
Kazakhstan. During her flight she spoke to Soviet Premier Nikita
Khrushchev.
Throughout the 1960s, US government resources were pumped into
NASA, enabling it to accelerate the space program. On July 31
1964, the first detailed photographs of the Moon were received
from Ranger 7, one of a series of unmanned probes sent to
the Moon by NASA.
Ranger 7 became the first American spacecraft to reach
the Moon, crash-landing on its surface as planned. The photographs
unravelled many mysteries about the Moon such as its age, the
characteristics of its soil and its general history.
Soviet cosmonaut Alexei Leonov left his Voskhod 2
spacecraft and walked through space in his orange spacesuit on 18
March 1965, attached to his craft by a cord. While his colleague
Pavel Belyaev watched from inside the Voskhod 2, Leonov
tested tools, took pictures and turned a somersault. His excursion
- the first space walk - lasted 10 minutes.
On 3 June 1965, Gemini 4 took US astronaut Edward White
100 miles above the earth for the first US space walk. He stayed
outside Gemini 4 for 20 minutes, tied to it by a nylon line
and using a jet-gas gun to move himself around. While outside,
White travelled 6,000 miles at a speed of 17,500 mph.
White did not want it to end - when he re-entered the
spacecraft he said it was the saddest moment of his life.
Tragically, White died in the Apollo spacecraft fire of
January 1967 which threatened for a while to block America's
attainment of the goal to land on the moon in the Sixties.
In order
to practice the delicate manoeuvring of spacecraft, on 15 December
1965, Wally Schirra and Thomas Stafford in Gemini 6 steered
to within one foot of Gemini 7, piloted by Frank Bormann
and James Lovell. Gemini 6 then chased Gemini 7 for
100,000 miles.
The first docking of craft in space was between Gemini 8
and an Agena rocket on March 17 1966. Later in 1966 Gemini 11
set an altitude record of 850 miles and NASA landed Surveyor 1
on the moon. It sent back data showing that the lunar surface was
smooth enough for the landing of a manned spacecraft.
In 1967 NASA began the Apollo
program, and in 1968 astronauts Broman, Lovell and Anders
orbited the moon in Apollo 8. The ultimate achievement came
on 21 July 1969 when Apollo 11 carried astronauts to the
moon and Neil Armstrong became the most famous human in history,
being the first to set foot on its
surface.
A second successful mission to the moon followed in November
with Apollo 12, when astronauts Charles Conrad and Alan
Bean walked on the moon.
The third planned moon landing in April 1970 was aborted when
an oxygen tank onboard Apollo 13
exploded. James Lovell, John Swigert and Fred Haise nursed the
damaged spacecraft around the moon and back to Earth, splashing
down safely on April 17.
On July 31 1971, David Scott and James Irwin of Apollo 15
were the seventh and eighth men to walk on the moon, but the first
to drive there in the Luna Rover - A vehicle invented by the
Boeing company which could speed across the moon's surface at 37
mph (60kph) and could be completely folded up and stored in the
spaceship. In 1972 the astronauts of Apollo 16 spent a
record 71 hours on the moon.
Apollo
17, launched in December 1972, was the last mission in the Apollo
program. The Luna Rover was used again by the astronaut and an
accompanying geologist who travelled 22 miles across the surface
of the moon, exploring the Taurus-Littrow Valley region.
The Russians launched the first space station, Salyut 1,
on 19 April 1971. The Americans followed two years later with Skylab
(a 100-ton manned space research laboratory) launched on 15 May
1973. Orbiting the earth for 84 days, Skylab broke all
previous endurance records.
In July 1975, the Soyuz and Apollo spacecraft,
launched independently from their bases in the USSR and the USA,
linked up 140 miles above the Atlantic Ocean. The two crews moved
freely around both ships for two days before finally separating
for the return journey to Earth.
In April 1981, a new kind of spacecraft took off from Cape
Canaveral. The initial flight of the reusable Space
Shuttle, Columbia, put the new spacecraft to the test.
Manned by two astronauts, Columbia orbited the Earth 36
times before landing safely, like a conventional aircraft, at an
airbase in California.
The first American woman in space was physicist Sally Ride who
flew onboard the Challenger
Space Shuttle on 18 June 1983.
Tragedy struck in 1986 when the Space Shuttle Challenger
ignited just 72 seconds after lift-off, killing its crew of seven
as the world watched in horror on live television. Onboard was
schoolteacher Christa McAuliffe, the first person to be chosen for
America's Civilians In Space Program.
And the race goes on. What happens next? Is there life on Mars?
Will the human race inhabit another planet? Only time will tell.
