The epoch of infinite geographic expedition began in 1957, when the Soviet Union launched the first

orbiter, Sputnik, into Earth orbit October 4, 1957. The Soviet besides were the first to establish a

manned ballistic capsule when Yuri Gagarni, made one orbit around the Earth in 1961. Americans

were electrified by the intelligence. A twelvemonth subsequently the Soviets issued an ultimatum that the Western

Allies evacuate Berlin. Next came a proposal that Berlin go a free metropolis. There waere frights

that the Cold War of coexistence could turn into a universe war.

America besides had ends they wanted to carry through. A twelvemonth subsequently the United States Congress

passed the National Aeronautics and Space Act to advance and organize the United States

infinite plan. In 1958 the National Aeronautics and Space Administration was established,

normally referred to NASA. Shortly after NASA s initiation, the launching site at Cape

Canaveral, Florida, and the Johnson Space Center in Houston Texas were planned and built.

Therefore making the infinite race.

Harmonizing to the 1958 act, NASA s maps are: to carry on research on jobs of

flight within and outside the Earth s atmosphere ; to develop, concept, trials and run infinite

vehicles ; to research infinite with manned and remote-controlled vehicles ; to collaborate with other states

on undertakings for the peaceable utilizations of infinite ; and to print the consequences of its work.

The planning and control of NASA s activities take topographic point at the bureau s central offices in

Washington, D.C. There are four plan offices that have been set up to develop and direct the

activities of NASA s several field installing: Office of Aeronautics and Space Technology,

Office of Space Science and Applications, Office of Space Flight, and Office of Space Tracking

and Data Systems.

The Office of Aeronautics and Space Technology is responsible for the continued

development of advanced engineering. This office set the guidelines for NASA s aims,

demonstrates the feasibleness of the aims, and proposes the necessary engineering to transport

them out. It besides coordinates activities with other bureaus to forestall duplicate of attempt.

The office of Space Science and Applications directs the survey of the nature of the

universe through research in astrophysics, biological science, Earth scientific disciplines, solar system geographic expedition,

communications, micro gravitation, and information systems. This office uses a vairety of devices to

behavior its research. These include remote feeling equipment, automated ballistic capsule, sounding

projectiles, balloons, and aircraft.

The Office of Space Flight is responsible for the infinite research labs and all aspects of the

Space Transportaion System, or infinite birds of NASA. This office besides directs several of the

field installings and oversees the purchase of all hardware necessary for NASA s infinite

plans.

The office of Space Tracking and Data Systems Provides all the information necessary

for the beginning and advancement of infinite missions. The installations that provide this

information support are the Deep Space Network, the Space flight Tracking and Data Network,

and the Tracking and Data Relay Satellite systems. A planetary communications system co-ordinates

the undertakings of this office by associating all tracking sites, control centres, and informations processing

facilities.NASA has nine main field installings. Many people who follow infinite launches know

of the Lyndon B. Johnson Space Center in Houston, Tex. , and the John F. Kennedy Space Center

at Cape Canaveral, Fla. The Houston installing is a bid control centre, while the centre

at Cape Canaveral is the primary launching site.

The other field installings are: Ames Research Center at Moffet Field, Calif. ; Goddard Space

Flight Center in Greenbelt, Md. ; the Jet Propulsion Laboratory in Pasadena, Calif. ; Langley

Research Center in Hampton, Va. ; Lewis Research Center in Cleveland, Ohio ; George C.

Marshall Space Flight Center in Huntsville, Ala. ; and the National Space Technology

Labs in Bay St. Louis, Miss.

Since it was founded, NASA has had many dramatic successes and at least two unfortunate

calamities. In 1961 Alan Shepard was the first American sent into infinite. The undermentioned twelvemonth John

Glenn became the first American to revolve the Earth. The most arresting accomplishment was seting

two work forces on the Moon in July 1969. The bureau & # 8217 ; s first major accident was the decease by fire in

1967 of spacemans Virgil Grissom, Ed White, and Roger Chaffee. The 2nd catastrophe was the

detonation of the Challenger infinite bird on Jan. 28, 1986. Less than two proceedingss after lift-off

all seven spacemans aboard were killed, including Christa McAuliffe, the first teacher-astronaut.

NASA launched its first U.S. Earth orbiter, Explorer I, on January 31, 1958. It was

launched at 10:48 P.M. from Cape Canaveral, Fla. It was bullet-shaped, 80 inches long and 6

inches in diameter with the last phase attached, and weighed 30.8 pound. Then in October 11, 1958

a Pioneer projectile was launched in an effort to circle the Moon. The mission failed on Oct. 12,

but the vehicle obtained a record upper limit height of 79, 193 miles-30 times the height of any

old adult male made object.

The first United States astronaut to come in infinite was Alan B. Shepard, Jr. His suborbital

flight, on May 5, 1961, in a one-person Mercury ballistic capsule carried him 115 stat mis above the Earth.

In 1959 John Glenn was selected as one of the Mercury Seven- the first seven spacemans

int eh United States infinite plan. On Feb. 20, 1962, he entered the infinite capsule Friendship 7

and began his historic mission, revolving the Earth three times within a five-hour period. The

success of the mission immediately boosted American morale, which had lagged during the Cold

War old ages because of the lead the Soviet Union had taken in the infinite race. Upon his return to

Earth, Glenn was hailed as a echt American hero and was honored with a ticker-tape parade

down Broadway in New York City. He besides received the Space Congressional Medal of Honor.

In 1962, President Jhon F. Kennedy had promised that the state would set down a adult male on

the Moon befor the dacade was over. Jhon F. Kennedy said, & # 8220 ; We choose to travel to the Moon and

disicate and do the other things. Not because they are easy, but because they are difficult. Because

that end will function to organize and mensurate the best of our energies and accomplishment. Because that

challenge is one that we are willing to accept, one we are unwilling to pospone, and one we

intend to win & # 8221 ; .

On July 31, 1964, Ranger 7 became the first United States ballistic capsule to snap the

Moon. All the early investigations either bypassed the Moon or crashed on it. The two-man Gemini

vehicles were the universe & # 8217 ; s first manoeuvrable manned ballistic capsule. In the first manned Gemini

flight & # 8211 ; that of Gemini 3, on March 23, 1965 & # 8211 ; Virgil I. Grissom and John W. Young completed

three orbits. On June 3, 1965, during the flight of Gemini 4, Edward H. White II became the first

American to walk in infinite.

The first rendezvous between two revolving ballistic capsule was accomplished on Dec. 15,

1965. Walter M. Schirra and Thomas P. Stafford maneuvered Gemini 6 to within a pes of

Gemini 7, in which Frank Borman and James A. Lovell, Jr. , set a space-flight endurance record

of 330 hours 35 proceedingss. In the succeeding Gemini flights, rendezvous and docking were

achieved with remote-controlled Agena mark vehicles. The plan ended in November 1966 with

Gemini 12.The foremost manned trial of the Apollo ballistic capsule was scheduled for 1967, but in January

1967, during a pattern countdown, Grissom, White, and Roger B. Chaffee were killed when a

flash fire swept the bid faculty in which they sat. The first manned Apollo ballistic capsule & # 8211 ;

Apollo 7 & # 8211 ; was launched on Oct. 11, 1968. Schirra, Donn F. Eisele, and Walter Cunningham were

in Earth orbit for 11 yearss.

In Apollo 8, launched on Dec. 21, 1968, Borman, Lovell, and William Anders became

the first work forces to revolve the Moon, finishing 10 lunar orbits. Apollo 11, launched on July 16,

1969, carried the first work forces to set down on the Moon. Command pilot Neil A. Armstrong and lunar

faculty pilot Edwin E. Aldrin, Jr. , landed in the Mare Tranquillitatis on July 20 at 3:17 Autopsy

CDT. At 9:56 PM Armstrong stepped onto the Moon. He was followed by Aldrin. Michael

Collins remained in the moon-orbiting bid faculty. Apollo 13, the 3rd mission planned

by the United States to set down work forces on the Moon. The mission about ended in calamity. An

detonation and power failure partly disabled the ballistic capsule & # 8217 ; s bid faculty, Odyssey, as it

neared the Moon. The astronauts & # 8211 ; ballistic capsule commanding officer James A. Lovell, Jr. , lunar faculty pilot

Fred Haise, Jr. , and bid faculty pilot John L. Swigert, Jr. & # 8211 ; were able to use their lunar

faculty, Aquarius, as a impermanent lifeboat, nevertheless, and carry through a safe return to Earth.

The Saturn V launch vehicle of Apollo 13 had lifted off from Cape Kennedy, Fla. , at 2:13

PM EST on April 11, 1970. The ballistic capsule was foremost inserted into Earth orbit, so boosted into

lunar flight by the Saturn projectile & # 8217 ; s 3rd phase. Transposition and moorage of Odyssey and

Aquarius were carried out, and by early eventide Apollo 13 was coasting toward the Moon on a

way so accurate that the first planned class accommodation was canceled. Later, the trade was

transferred to a non-free-return flight to ease the planned landing in the Fra Mauro

part of the Moon. The transportation meant that, should no farther propulsive manoeuvre be made

during the flight, Apollo 13 would swing around the Moon and return toward Earth, but would

girls Earth by 2,950 stat mis ( 4,750 kilometres ) .

Sunday, April 12, passed without incident, and early Monday eventide, about 56 hours into the

flight, Lovell and Haise entered Aquarius and began look intoing systems. Suddenly a loud knock

was heard, and electrical power failed in Odyssey. Swigert radioed Mission Control in Houston,

Tex. , with the baleful message, & # 8220 ; Hey, we & # 8217 ; ve had a job here. & # 8221 ; Much later, the knock was

discovered to hold been an oxygen-tank detonation in Odyssey & # 8217 ; s service faculty. It disabled the

three fuel cells that usually provided electricity and imbibing H2O for the bid faculty.

( Swigert had replaced scheduled pilot Ken Mattingly after Mattingly was exposed to rubeolas

merely yearss before the launch. )

With programs for a lunar

landing abandoned, the spacemans transferred into the lunar faculty,

Aquarius, which had sufficient power, O, and H2O to prolong them while the crippled

ballistic capsule swung around the Moon and returned toward Earth. The systems of the Odyssey & # 8211 ; the

merely faculty that could reenter the Earth & # 8217 ; s atmosphere & # 8211 ; were shut down to conserve its

exigency battery power. Early Tuesday forenoon, as the ballistic capsule neared the Moon, Aquarius & # 8217 ;

engine was fired to set it into a free-return flight. Then, as expected, Apollo 13 lost wireless

contact with Earth as it passed behind the Moon, but communicating was shortly reestablished

when the trade emerged from behind the Moon. At about this clip the long-discarded Saturn

3rd phase crashed into the Moon as planned, supplying an unreal moonquake for scientists to

survey.

Some two hours subsequently, Aquarius & # 8217 ; engine was fired once more to increase the ballistic capsule & # 8217 ; s speed,

cut down its flight clip by 10 hours, and guarantee a splashdown in the Pacific Ocean South of

Samoa. Meanwhile, C dioxide degrees in the lunar faculty began to lift to unsafe degrees

as the ballistic capsule & # 8217 ; s lithium hydrated oxide absorbers became concentrated. The air purifiers in the

bid faculty did non suit the Aquarius, so NASA applied scientists were forced to improvize a

purification system, radioing the spacemans elaborate instructions on how to piece it from the

stuffs available on the ballistic capsule. The hurriedly designed system worked good, maintaining the

C dioxide content of the air good below risky degrees for the balance of the mission.

A farther class rectification was made Wednesday forenoon. Fixing to reenter the Earth & # 8217 ; s

atmosphere, the spacemans foremost discarded the service faculty, taking valuable exposure of the

damaged subdivision as it separated. They so transferred into the bid faculty and discarded

the lifesaving Aquarius, which could non return to Earth. The bid faculty entered the

atmosphere and splashed down on mark, 142 hours, 54 proceedingss, and 41 seconds after the

mission began. A recovery squad from the aircraft bearer USS Iwo Jima picked up the spacemans

on April 17, and they were flown to Hawaii to run into their households. President Richard Nixon, on

his manner to see the Apollo 13 crew, stopped in Houston to present the Presidential Medal of

Freedom, the state & # 8217 ; s highest civilian award, to the full Mission Control squad.

In the aftermath of the near-disaster, NASA appointed a reappraisal board under the leading of

Edgar M. Cortright, manager of Langley Research Center, to look into the Apollo 13 accident.

After some three months of survey, the cause of the detonation was traced to two inadequate

thermostatic switches in an oxygen-tank warmer assembly. Dysfunction of the switches under

burden caused overheating that led to an insularity fire, and the subsequent blast tore a side panel

from the service faculty and disabled the fuel cells. Other defects in industry and in proving

processs were besides found. Further Apollo flights were delayed until 1971 so that alterations

could be made to forestall similar incidents. During the 1970s the United States developed the

infinite bird, the first reclaimable manned infinite vehicle. It combined three systems: a winged

satellite transporting crew and warhead ; an external armored combat vehicle with propellent for the three chief projectile

engines ; and duplicate solid projectile supporters to raise the trade above the thickest portion of the ambiance.

The supporters were designed to jump into the ocean for recycling, and the satellite glided back

to a track at the terminal of its mission.

The plan began with a sum of four infinite birds ; they were named for celebrated

oceangoing ships: Columbia, Challenger, Discovery, and Atlantis. The Columbia flew four

orbital trial flights from April 1981 to July 1982. The first flight ( STS 1 ) was flown by spacemans

John W. Young and Robert Crippen. The following three flights carried warheads to show the

bird & # 8217 ; s public-service corporation as a bearer. Get downing with the STS 5 in 1982, the bird carried operational

warheads.

The bird Challenger made its first flight in April 1983. On its following acclivity, in June, the crew

included the first American adult female in infinite, Sally K. Ride. Columbia went up once more in

November transporting Spacelab 1, a extremely complex research lab faculty. In February 1984

spacemans Bruce McCandless II and Robert L. Stewart used gas-jet propulsion back packs called

manned steering units ( MMUs ) to travel and work in infinite and return to the bird

Challenger while free of any line of life to the ballistic capsule.

On Jan. 28, 1986, after 24 successful launches, the shuttle Challenger exploded 73 seconds

after lift-off. Its seven crew members were killed, including schoolteacher Christa McAuliffe,

the victor of a countrywide teacher-in-space competition. The shuttle plan was suspended until

the exact cause of the detonation could be found. The United States returned to infinite in 1988

with the launching of the infinite bird Discovery in September. The mission reflected 100s

of design alterations. In December 1988 and once more in May 1989, Atlantis made successful flights.

In 1991 the United States replaced the shuttle Challenger with the new Endeavour. In 1996

NASA announced programs to construct a new experimental reclaimable projectile that would replace the first

coevals of infinite birds, perchance taking to big decreases in the cost of raising warheads

into infinite. By mid-1998, NASA had launched a sum of 90 shuttle missions.

In 1996, the United States launched the Mars Global Surveyor, the first of three remote-controlled

ballistic capsule designed to examine the surface of the planet Mars. The launching of the investigation, which

arrived at its finish on September 11, 1997, marked the beginning of a ten-year run to

cod information about the geological make-up of Mars and to find whether or non any

lifeforms, no affair how crude, existed, or go on to be, on the planet.

The launch of the Global Surveyor was followed by the launching of another American trade,

the Mars Pathfinder, in early December 1996 ; unlike the earlier trade, the Pathfinder was

designed to set down on the surface of Mars. A Russian trade, the Mars 96 investigation, was launched ten

yearss after the Mars Global Surveyor but crashed shortly after takeoff. The Pathfinder mission

landed on Red planets on July 4, 1997, the first remote-controlled investigation to set down on Mars since the 1976 Viking

infinite missions. The Pathfinder, which featured a six-wheeled robotic wanderer called Sojourner,

was ab initio scheduled to be operational for merely 30 yearss, but continued to execute until

September 1997, when it sent back its last batch of information. Repeated efforts were made

to reach the investigation ; nevertheless, by March, 1998, NASA functionaries accepted that the investigation was no

longer functional.

The Soviet Union launched a infinite bird, Buran ( Blizzard ) , on an remote-controlled mission in

November 1988. It completed two orbits of the Earth and was unusually similar to the United

States shuttle except for the design of the launch vehicle.

In January 1998, the National Aeronautics and Space Administration ( NASA ) to let John

Glenn to return to infinite. Agency functionaries announced that the 76-year-old former spaceman will

be aboard the infinite bird Discovery for a mission scheduled to establish in early October 1998.

Glenn, who made history in 1962 as the first American to revolve the Earth, would gain another

topographic point in the record books as the oldest individual to go into infinite. He was scheduled to function as

a warhead specializer aboard a flight of Discovery, carry oning space-related research on the

effects of aging.

In denoting the intelligence to the imperativeness, NASA decision maker Daniel S. Goldin stressed the

combination of difficult experience and antique heroics that Glenn would convey to the

Discovery mission. Mentioning the senator & # 8217 ; s experience as a Marine trial pilot and spaceman, Goldin

stated that Glenn & # 8220 ; brings a alone blend of experience to NASA. He has flight, operational, and

policy experience. Unlike most spacemans, he ne’er got the chance for a 2nd flight. He is

portion of the NASA household, an American hero, and he has the right material for this mission. & # 8221 ;

At a NASA imperativeness conference, the senator explained that his desire to fall in the Discovery

mission stemmed non merely from a love of infinite travel, but besides from his involvement in utilizing infinite

flight to analyze certain facets of aging. Space flight and the aging procedure portion several

physiological responses such as bone and musculus loss, balance upsets, and sleep perturbations.

Because of these similarities, scientists believe that infinite flight itself can function as a theoretical account

system for research into the procedures of aging.

Senator Glenn was instrumental in advancing the usage of infinite flight for the benefit of healthy

and productive ripening. He studied the similarities between infinite travel and aging on his ain, and

get downing in 1996 he persisted in seeking to convert Goldin and other NASA functionaries to allow

him to go in infinite to transport out firsthand surveies. The senator reasoned that if he could go through

the physical, he would be good qualified for the mission. Dr. Robert Butler, a professor of

Geriatricss at Mount Sinai Medical Center and manager of the International Longevity Center,

stated that Senator Glenn would be & # 8220 ; peculiarly good qualified since he has done this before, and

because of his work with NASA and the National Institute on Aging to develop research that will

lead to a better apprehension of the effects of aging. His engagement makes a bold statement

about the capablenesss of older people and will assist us understand the effects of aging and infinite

flight. Senator Glenn & # 8217 ; s bravery and willingness to set about this mission are notable. & # 8221 ;

Harmonizing to NASA flight sawboness, Glenn is in first-class physical status. After go throughing a

battery of compulsory medical trials, he was pronounced medically qualified to wing. NASA

maintained medical records on Glenn for 42 old ages, and therefore was able to execute an thorough

medical rating.

As a Marine combatant pilot in World War II and Korea, Glenn flew 149 missions, defying

11 hits by enemy fire. Following the Korean War, he served as a trial pilot for several old ages,

working with Navy and Marine Corps jet combatants and onslaught aircraft. In 1957, Glenn set a

transcontinental velocity record from Los Angeles to New York. He still flies his ain plane, and

he set a record for velocity on a flight from Dayton Ohio to Washington D.C.
