Space Shuttle Challenger cost $3.2 billion, Space shuttle Atlantis cost $10.6 billion. Space Shuttle Endeavour costs approximately $1.7 billion. Total time takes eight and a half minutes. The space shuttle needs to accelerate from zero to 8000 meters per second or 18000 miles per hour to reach the minimum altitude needed to orbit the earth. The fuel pump alone can deliver 71000 horsepower and the oxygen pump delivers 23000 horsepower. On average three space shuttle main engines generate about 37 million horsepower. How Much Horsepower Does The Space Shuttle Have? But on average a space shuttle uses around 4,578,000 pounds or 2,076,545 kg of fuel. It actually varies depending on missions. How Much Fuel Does A Space Shuttle Use To Get To The Moon? That is two million times the rate a family car burned fuel. How Much Fuel Does Space Shuttle Use?ĭuring the liftoff, two solid rocket boosters can consume 11000 pounds of fuel per second. Space shuttle Challenger was weigh around 80600 kg or 177700 pounds on Dry mass. How Much Did The Space Shuttle Challenger Weigh? Its empty external tank weighs 78000 pounds and two solid rocket boosters weigh 185000 pounds on empty. How Much Does An Empty Space Shuttle Weigh?Īn empty space shuttle weighs around 165000 pounds. NASA and its Shuttle contractors setup rules and systems to handle what has produced over 130 RLV launches, but they have had many challenges. Their failed mission was in 19 respectively by Challenger and Columbia. And those many successful missions have resulted in many benefits for the earth. Among them 135 were successful and 2 were failed. The first space shuttle Enterprise has never been launched and used for atmospheric flight tests.īetween 1981 to 2011 NASA has conducted 135 missions. The orbiter stops about midway to three-quarters of the way down the runway.NASA has built only six massive space shuttle which include Atlantis, Challenger, Columbia, Discovery, Endeavour and Enterprise. The parachute and the speed brake on the tail increase the drag on the orbiter. A parachute is deployed from the back to help stop the orbiter. materials selected for stability at high temperatures and weight efficiency. The commander brakes the orbiter and the speed brake on the vertical tail opens up. That day we lost our second space shuttle (orbiter) and the first accident. The pilot deploys the landing gear and the orbiter touches down. When the orbiter is 2,000 ft (610 m) above the ground, the commander pulls up the nose to slow the rate of descent. During the final approach, the commander steepens the angle of descent to minus 20 degrees (almost seven times steeper than the descent of a commercial airliner). The commander flies the shuttle around an imaginary cylinder (18,000 feet or 5,500 m in diameter) to line the orbiter up with the runway and drop the altitude. At 25 miles (40 km) out, the shuttle's landing computers give up control to the commander. The commander picks up a radio beacon from the runway (Tactical Air Navigation System) when the orbiter is about 140 miles (225 km) away from the landing site and 150,000 feet (45,700 m) high. The orbiter makes a series of S-shaped, banking turns to slow its descent speed as it begins its final approach to the runway. At this point, flight computers fly the orbiter. With this design, the orbiter can generate lift with a small wing area. The orbiter is designed from a lifting body design with swept back "delta" wings. When re-entry is successful, the orbiter encounters the main air of the atmosphere and is able to fly like an airplane. The hot ionized gases of the atmosphere that surround the orbiter prevent radio communication with the ground for about 12 minutes (i.e., ionization blackout). During re-entry, the aft steering jets help to keep the orbiter at its 40 degree attitude. In other words, they have a high heat capacity. These materials are designed to absorb large quantities of heat without increasing their temperature very much.
