Space Shuttle Endeavour was the fifth and ultimate operational shuttle constructed as a part of NASA’s Space Shuttle programme. During its practically twenty years of lively responsibility from May 1992 to May 2011, Endeavour launched into 25 successful missions. A.S.Ganesh takes a take a look at a few of the highlights from Endeavour’s voyages…
The Space Shuttle Challenger catastrophe, which noticed the shuttle break aside 73 seconds after launch throughout its tenth mission, shook the U.S. and the world. It modified the way in which NASA functioned without end. Of the many adjustments that got here was the delivery of Endeavour, the fifth and ultimate area shuttle to be constructed by NASA as a part of the Space Shuttle programme.
Even although Endeavour was born of a tragedy and constructed to switch the Challenger that had been misplaced, it was extremely successful. Using spare components from its shuttle fleet, together with these components pre-fabricated in the course of the growth of Discovery and Atlantis, NASA accomplished the brand new orbiter in 1991.
How to call it
Sensing a chance to get some constructive press, NASA determined to have a contest for U.S. faculties to call the shuttle whereas it was nonetheless below building. The NASA Orbiter-Naming Project, which set out the necessities for the title, attracted entries from over 6,000 faculties, representing practically 70,000 youngsters.
As the shuttle needed to be named after an “exploratory or research sea vessel”, numerous entries selected the identical title: Endeavour. The Endeavour was an 18th-Century British vessel best-known for its maiden voyage throughout which Captain James Cook charted the South Pacific and commanded the vessel to Tahiti to look at the transit of Venus throughout the solar.
Endeavour’s first flight in itself was a difficult one. Launched on May 7, 1992, the mission was tasked with salvaging the Intelsat-VI communications satellite tv for pc that had been launched right into a low-altitude orbit.
First problem
Finding it unattainable to seize with the instruments that they had, the crew labored out a distinct resolution. For the primary time, three astronauts carried out a spacewalk collectively that enabled them to get well the satellite tv for pc. Once within the payload bay, the astronauts repaired it and despatched it out on its approach to begin its service and help the dwell broadcast of the 1992 Summer Olympics.
When Endeavour landed again on Earth on May 16, 1992 after efficiently finishing its maiden voyage, a drag chute was launched from the orbiter’s tail – one of many extra seen security measures that had been added to the shuttle fleet following Challenger’s loss.
During its subsequent flight in 1992, Endeavour’s seven-member crew included the primary feminine African-American astronaut Mae Jemison in addition to the primary married couple to fly collectively in area, Americans Mark Lee and Jan Davis.
Hubble servicing mission
In its fifth mission in 1993, Endeavour ferried the primary Hubble Space Telescope restore crew. Following Hubble’s deployment, it was found that the telescope’s main mirror had a small however vital flaw. During the 11-day mission, astronauts carried out a then-record 5 spacewalks to suit Hubble with corrective optics and different science devices, together with new photo voltaic arrays.
Endeavour had the honour of being deeply concerned within the building and meeting of the International Space Station (ISS). And although it’s best remembered for launching satellites and constructing the ISS, Endeavour’s crews additionally carried out hundreds of hours of science experiments.
Endeavour’s final area mission reached orbit on May 16, 2011. In its practically twenty years of lively service, Endeavour carried out 25 missions, clocking practically 300 days in area.

As there have been calls to accommodate the Endeavour completely, the California Science Center was chosen because the shuttle’s everlasting residence after retirement. This, nonetheless, proved to be a logistical problem because the Endeavour needed to make a 19-km journey by street to get to its new residence.
Workers reduce down bushes to make room for Endeavour alongside its means. It took it far longer than flying to area, as Endeavour needed to manoeuvre previous poles, bushes and some other obstacles alongside the roads. It lastly reached the museum in October 2012, the place it’s now on show.
