History of Space Exploration

In our history many great things have happened. We
have been inventing and exploring things since day one.
Many of these things that we discovered or invented we
thought would never be possible in earth’s life time. But they
exists now, today, they are used by almost every human
being and there are many more incredible and unmanageable
things to come and aid us in every day life. One of the most
interesting things to me would fall under exploration and
inventing. You are about to venture in to the history of
space and learn how man and mans objects have gotten

The exploration in space dates back over 40 years ago,
January, 31 of 1958 to be exact. On this date Explorer 1,
which was the first U.S. satellite to be fired in space and its
unknown, to orbit earth. It lifted off from Cape Canaveral
using a modified Jupiter-C rocket called ABMA-JPL. It
carried a scientific experiment of James A. Van Allen, and
discovered the Earth’s radiation belt.Along with defeat and
triumph also come disappointment and failure. In March 5
of 1958 Explorer 2 was launched by another Jupiter-C
rocket and failed to reach orbit. October 1, 1958 NASA
was founded, taking over existing National
Advisory Committee on Aeronautics and only ten days later
U.S. – IGY space probe was launched to a incredible height
of 70,700 miles. On March 3 of 1959 Pioneer 4, an
U.S.-IGY space probe is launched by a Juno II rocket, and
achieves an earth-moon trajectory, passing within 37,000
miles of the moon. It then fell into a solar orbit, becoming the
first U.S. sun orbiter. About a year later Tiros 1 was fired
into earth’s orbit and became the first successful weather
satellite for the United States.Then on August 18 of the
same year, 1960, Discoverer XIV was launched and
became the first U.S. camera-equipped Corona spy satellite.

On July 14, 1965, They U.S. Mariner 4 returned the first
close-range images of Mars. The above paragraph explains
some of the earliest satellites, spy satellites, and probes that
were sent into space to explore the unknown and the
May 5 of 1961 Mercury Freedom 7 carried Alan B.

Shepard, Jr., who was the first U.S. astronaut in space, in a
suborbital flight. This United States’ first manned space flight
project was successfully accomplished in a 4 2/3 year period
of dynamic activity. During this time they saw more than
2,000,000 people from many major government agencies
and much of the aerospace industry and combined their
skills, initiative, and experience into a national effort. Also
during this 4 and 2/3 period six other manned space flights
were accomplished as part of a 25-flight program.These
manned space flights were accomplished with complete pilot
safety and without change to the basic Mercury concepts. It
was shown that man can function ably as a
pilot-engineer-experimenter without undesirable reactions or
deteriorations of normal body functions for periods up to 34
hours of weightless flight. And so we continue or fight
through this history of space exploration.

February 20 of 1962 Mercury Friendship 7 lifts off with
John H. Glenn, Jr., who was the first American in orbit, and
orbits the Earth three times.In July 31, 1964 U.S. Ranger
7 relayed the first close range photographs of the moon.
Probably more spectacular than man orbiting earth would be
a space walk.The united state accomplished this in 1965
on Jun 3rd. Edward White II made the first U.S. space
walk from space vehicle Gemini 4. The duration of the space
walk was 22 minutes, which was the longest up to this date.

December 4 of 1965 was a great day.Gemini 7 was
launched carrying Frank Borman and James A. Lovell, Jr.,
which made 206 orbits around Earth and proving a trip to
the moon possible. A year later the US does the next best
thing from sending a person to the moon and sent Surveyor
1 which was the first U.S. spacecraft to soft-land on the
moon. December 21, 1968 Apollo 8 and its four crew
members were the first Apollo team to make orbit around
the moon, they actually made ten orbits around the moon.

July 20, 1969 only 30 years ago Neil Armstrong and
Edwin Aldrin, Jr. make the first manned soft landing on the
moon. Not only this they were the first moonwalk and this
trip was made possible because of Apollo 11 mission.
Skipping a head a few years we find that on September 3,
1976 Viking 2 landed on Mars at the Plain of Utopia,
where it discovered water frost. We have come a long way
since 1858 to 1976 and we are now going to jump into the
last nine years of our history. April 24, 1990 Space shuttle
Discovery embarks on mission STS-31, deploying the
Edwin P. Hubble Space Telescope. In September 26 of
1996 the United states came back holding the record of
staying in space for the longest time. This could be the key
to getting us farther places leading to more exploration, only
time will tell. Towards the end of 1996 The US started to
survey mars and gather information from it. July 4, 1997 –
The Mars Pathfinder arrived at Mars and took pictures of
the planet. The data collected encourages scientists to
believe the planet may once have harbored
life. The planet is much more like Earth than previously
suspected. On the date of December 21st 1998 the Us
Announced that Chandra X-Ray Observatory would be put
into space. This made it the largest object put into space
and was made to help scientists understand the structure and
evolution of the universe. And last but not least on April 16,
1999 NASA launched Landsat-7. It will locate urban “hot
spots” that may alter local climates, and monitor the effects
from deforestation in Central American rain forests.

Here is a quote that I found interesting. I will write down
the quote and tell who said it and why I chose this quote.
The first quote is written by JFK. “We choose to go to the
moon in this decade to do the other things..Not because they
are easy but because they are hard” I chose this quote
because it is say that we strived beyond the easy and
imaginable to the hard and unimaginable.
Above you have read many things that the US has
discovered and explored in space. I picked this topic
because I like space and I enjoy learning about it.It is nice
to day dream that someday we might be living on some
distant planet.These events and people were very
important to our history because if it was not for them we
would not know anything about space. We would also not
be one step closer to be living on another planet. Thank you
for reading.
