Space Shuttle Launch
April 5, 2010 by Post Team
Discovery blasted off from launch pad 39A at Kennedy Space Center in Cape Canaveral, Florida at 6:21 am (1021 GMT) when two rocket boosters scheduled.The, representing 80 percent of the shuttle, lift the administrative officers during the off, peel as planned 120 seconds after launch. They fell into the Atlantic Ocean, where they will be recovered and reused later.
The shuttle arrived at the Earth’s orbit eight minutes administrative officers and a half after launch, moving at five times the speed of sound to reach 16,155 miles (26,000 kilometers) per hour.Once it enters orbit 140 miles (225 kilometers) above Earth, Discovery will begin its run to the ISS, is 213 miles (343 kilometers) above Earth.
Discovery, the AM due to arrive to the International Space Station is tentatively scheduled for Wednesday and will be a final mission for the shuttle program, which will be closed later this year.
It is the first shuttle mission with three female crew members and also mark the first time in space, with four women in orbit.Only three space shuttle flights planned before the three remaining U.S. manned orbiters are retired in late 2010, ending 30 years of service. The shuttle flew in April 1981.
During the 13-day mission, Discovery and its crew delivered about eight tons of cargo, including spare beds for the occupants of the space station, a large tank of ammonia coolant and seven racks full of science experiments Tracy Caldwell. Dyson came to the American space station on Sunday aboard a Russian Soyuz spacecraft with two Dyson cosmonauts.Joining be Dottie Metcalf Discovery mission specialists-Lindenburger, 34, a former science teacher in school, Stephanie Wilson , 43, a veteran of two shuttle missions, and Naoko Yamazaki, 39, an astronaut of the Japanese space agency since 1996.
Rounding out the crew of the Discovery mission commander, Alan Poindexter, 48, co-pilot Jim Dutton, 41, mission specialist and astronaut Rick Mastracchio, 50, and fellow astronaut Clay Anderson, 51. Among the arts of being carried into space is a freezer to preserve blood samples, urine, saliva, plants or microorganisms used in microgravity experiments and thenanlyzed later on Earth.
Discovery is also carrying an exercise machine designed to study the effects of microgravity on the body, AOS musculoskeletal system. Muscles can atrophy during long stays in space for astronauts must be careful to exercise regularly.
Supplies, racks and other equipment are placed in a pressurized module built Italian named Leonardo, made in the shuttle, the construction of administrative officers bay.Until completing the space station, NASA has to carry spare parts and equipment to maintain the space station and service of scientific experiments on board.
Two Discovery astronauts made three spacewalks lasting six hours each day five, seven and nine of the mission.One of its largest and most complex tasks will be to replace an empty ammonia tank attached to the rear station with one that is full. Ammonia is used in the station cooling AOs system.he ISS, a project of one hundred billion dollars started in 1998 with the participation of 16 countries, is primarily funded by the United States.

In presenting his budget proposal in February 2011, President Barack Obama announced that the space station will continue at least until 2020.
Once the shuttle program ends, the United States depend on the Russian Soyuz spacecraft to transport astronauts to the ISS until a new U.S. launch vehicle is ready to take over around 2015.
