vehicles venture far beyond the boundaries of the earth to collect valuable information

about the universe. Human beings have visited the moon and have lived in

space stations for long periods. Space exploration helps us see the earth in its true relation

with the rest of the universe. Such exploration could reveal how the sun,

the planets, and the stars were formed and whether life exists beyond our own world.

We

do not know the boundaries of the universe or what advances can come out of these

explorations so we must thrust our emotions into the unknown and have an open mind to

the possibilities. So while the average person is wondering what space has to offer the

person do not realize the many missions that have already went on in this field.

The exploration of bodies in the solar system began within a few years of the first

satellites.

In 1926 American scientist Robert H. Goddard launched the world’s first liquid-

propellant rocket.

Then both U.

S. and Soviet space engineers set their sights on the Moon.

Early Soviet launches in 1958 all failed and were never announced. Several U.S.

launches also failed, although two of them (Pioneers 1 and 3) reached nearly

100,000 km into space before falling back to Earth.

In 1958 a great leap occured

when The National Aeronautics and Space Administration (NASA) was formed.

This program is what runs all the space ideas and puts them into action

The first probe to escape Earth’s gravity was the Soviet LUNA 1, launch on

Jan. 2, 1959, which passed the Moon and continued into interplanetary space

. The U.S. probe Pioneer 4, launched two months later,

followed the same path.

Later Soviet probes either hit the

Moon or passed it and took photographs of the hidden far side, relaying them back to

Earth. The space age began on Oct. 4, 1957. On that day, the Soviet Union launched

Sputnik 1, the first artificial satellite to orbit the earth.

The first manned space flight was made on April 12, 1961, when Yuri A. Gagarin,

a Soviet cosmonaut, orbited the earth in the spaceship Vostok 1.

Space probes have vastly expanded our knowledge of outer space, the planets, and

the stars. In 1959, one Soviet probe passed close to the moon and another hit the moon.

A United States probe flew past Venus in 1962. In 1974 and 1976, the United States

launched two German probes that passed inside the orbit of Mercury, close to the sun.

Two other U.S.

probes landed on Mars in 1976. In addition to studying every

planet except Pluto, space probes have investigated comets and asteroids.

The first manned voyage to the moon began on Dec. 21, 1968, when the United States

launched the Apollo 8 spacecraft. It orbited the moon 10 times and returned to the earth.

On July 20, 1969, U.

S. astronauts Neil A. Armstrong and Edwin E. Aldrin, Jr., landed

their Apollo 11 lunar module on the moon. Armstrong became the first person

to set foot on the moon.

United States astronauts made five more landings on the moon

before the Apollo lunar program ended in 1972.

The early years of the space age, success in space became a measure of a country’s

leadership

in science, engineering, and national defense. The United States and the Soviet Union

(4)

were engaged in an intense rivalry called the Cold War. As a result, the two nations

competed with each other in developing their space programs. Throughout the 1960’s

and 1970’s, this ;space race; drove both nations to tremendous exploratory efforts.

During the 1970’s, astronauts and cosmonauts developed skills for living in space

aboard the Skylab and Salyut space stations.

In 1987 and 1988, two Soviet

cosmonauts spent a record 366 days in orbit.

In the mid-1960s three NASA programs pursued the lunar objective. Ranger probes

crashed into the Moon’s surface but succeeded in sending high-resolution

photographs prior to impact. SURVEYOR probes soft-landed on the Moon and

analyzed its surface, while Lunar orbiters probes circled the Moon and sent

back pictures both of potential landing sites for astronauts and .
