HUBBLE SPACE

In 1962, the USA's National Academy of Sciences recommends building a large space telescope. In 1977Congress votes to fund the project and construction of Hubble Space Telescope begins.
Hubble Space Telescope History
Construction of Hubble Space Telescope was completed in 1985The launch of Hubble was delayed due to the 1986 Space Shuttle Challenger disaster. Hubble was launched on the space shuttle on April 25, 1990. It was named after Edwin Hubble.

Within days Hubble 
was sending back pictures that were out of focus. NASA discovered a major flaw in the giant mirror. The giant mirror was too flat on one edge by 1 / 50th of the width of a single human hair.
In December, 1993, the Space Shuttle Endeavor captured and modified the Hubble Space Telescope by adding a camera to correct problems with the telescope's primary mirror.
The second servicing mission was in february 1997. Astronauts exchanged some of Hubble's instruments and added new blankets to keep Hubble warm.
On October 1997NASA decided to extend Hubble's operations from 2005 to 2010.
On November 13, 1999, a fourth gyroscope on Hubble fails. The Hubble shuts down to await a repair mission since it can no longer aim. Space Shuttle mission repairs the Hubble and upgrades it.
Great Achievements of Hubble
June 1994: NASA releases Orion Nebula images that confirm the births of planets around newborn stars.
November 1995: NASA releases Eagle Nebula images showing where stars are born.
January 1996: NASA releases the "Deep Field" images in which Hubble peers back in time more than 10 billion years. Reveals at least 1,500 galaxies at various stages of development.
February 2001: New images "ant nebula".

NEIL ARMSTRONG

                                                        Neil Armstrong is famously known as the first man to walk on the Moon. He is a former American test pilot and U.S. astronaut and is currently retired. He was a test pilot on the X-15 rocket plane and commander of Gemini 8 and Apollo 11 missions.

Neil Armstrong Biography
Neil Armstrong was born on 5th August, 1930 in Wapakoneta, Ohio, USA. His full name is Neil Alden Armstrong.
Neil Armstrong was interested in aviation from a young age. At 15 he worked in various jobs in order to pay for his flying lessons. At 16 he got his student pilot's licence before he was legally old enough to drive a carand before he graduated from Blume High School in Wapakoneta in 1947.
Immediately after high school, Neil Armstrong received a scholarship from the U.S. Navy. He enrolled at Purdue University in West Lafayette, Indiana and began his studies of aeronautical engineering, but in 1949 the Navy called him to active duty.
In 1950 he was sent to Korea and served as a naval pilot during the Korean War. He flew 78 combat missions from USS Essex in a Grumman F9F-2 Panther. He received three medals: the Air Medal and two Gold Stars for his military service during the Korean War.
After the war, he left the Navy and returned to Purdue in 1952 and graduated with a Bachelor of Science degree in Aeronautical Engineering.
In 1955 Neil Armstrong joined NACA (National Advisory Committee for Aeronautics - now known as NASA) as a research pilot at the NACA Lewis Research Center in Cleveland, Ohio. Later that year hetransferred to the NACA High Speed Flight Station (now NASA's Dryden Flight Research Center) at Edwards Air Force Base in California where he worked as a test pilot for many experimental high speed aircraft including the X-15. From 1960 to 1962 he was a pilot involved in the X-20 Dyna-Soar orbital glider program.



In 1962 while serving as a test pilot, Neil Armstrong was selected by NASA to join the second group of NASA's astronaut trainees (one of nine NASA astronauts). He moved to El Lago, Texas, near Houston's Manned Spacecraft Center to begin his astronaut training and underwent 4 years of intensive training for the Apollo program. His first assignment was as backup command pilot for the Gemini 5 mission in 1965.

In 1968, Neil Armstrong was chosen to be a member of the Apollo 11 mission, the first manned lunar landing. The Apollo 11 crew were: Neil Armstrong, Michael Collins and Edwin 'Buzz' Aldrin.
Apollo 11 was launched on July 16, 1969 from Cape Kennedy, Florida by a Saturn V rocket. Four days later it went into orbit around the Moon. The lunar module Eagle separated from the Command Module with Armstrong and Aldrin aboard and descended to the surface of the Moon. Michael Collins remained in the Command Module in orbit.
During the moon landing, Armstrong took manual control of the Lunar Module Eagle and piloted it away from a rocky area and made a safe landing on the moon. His first words from the Moon were:"Houston, Tranquility Base here. The Eagle has landed".
Neil Armstrong was the first person to walk on the moon on July 20, 1969. His first words after stepping on the moon were, "That's one small step for a man, one giant leap for mankind". This event was televised to Earth and seen by millions! The Apollo 11 crew returned safely to Earth on July 24, 1969.


Neil Armstrong resigned from NASA in 1971 and became a professor of aerospace engineering at the University of Cincinnati, where he was involved in both teaching and research until 1979.
During the years 1982-1992, Armstrong was chairman of Computing Technologies for Aviation Inc., Charlottesville, Virginia.
In 1986, he was appointed as vice chairman of the presidential commission that investigated the Challenger Space Shuttle disaster.
From 1989 until he retired in 2002, he served as chairman of AIL Technologies (Deer Park, New York), an electronics and avionics manufacturer.


Did you know?
* Neil Armstrong is one of only 12 people that have walked on the Moon's surface in the 20th century. A lunar crater close to Apollo 11 landing site is named after him in his honour.
* Neil Armstrong narrowly escaped death during training in the crash of a Lunar Landing Research Vehicle on May 6, 1969.
* The Neil Armstrong Air and Space Museum is located at 500 South Apollo Drive, Wapakoneta, Ohio, USA. The museum is open year round. It opened in 1972. Highlights include: Gemini 8 Spacecraft flown by Armstrong and David Scott in 1966, Armstrong's Gemini and Apollo space suits, Moon rock brought by Apollo 11 crew and many other exhibits.










DOG IN SPACE

The First Animal in Space was Laika - Soviet/Russian space dog aboard Sputnik 2 in November 2nd, 1957.

Albert II, a Rhesus Monkey, became the first monkey in space on June 14, 1949.

Sputnik 5 (also known as Korabl-Sputnik 2) carried the dogs Belka and Strelka on August 19, 1960. It was the first spacecraft to carry animals into orbit and return them alive.

Ham was the first chimpanzee (monkey) in space. He flew on a suborbital flight on January 31, 1961 in a Mercury spacecraft launched on a U.S. Redstone rocket. The launch site was Cape Canaveral, Florida.

France flew the first rat (Hector) into space on February 22, 1961. Two more rats were flown in October 1962.
