The fleet has taken astronauts on dozens of successful missions, resulting in immeasurable scientific gains. But this success has had a serious cost. In 1986, the Challenger exploded during launch. In 2003, the Columbia broke up during re-entry over Texas. Since the Columbia accident, the shuttles have been grounded pending redesigns to improve their safety. The 2005 shuttle Discovery was supposed to initiate the return to flight, but a large piece of insulating foam broke free from its external fuel tank, leaving scientists to solve the mystery and the program grounded once more until July 2006, when the Discovery and Atlantis both carried out successful missions. In <a href="http://git.ringzle.com:3000/taniaaou446274">Check this out</a> article, we examine the monumental technology behind America's shuttle program, the mission it was designed to carry out, and the extraordinary efforts that NASA has made to return the shuttle to flight. The space shuttle flight path.</p><br/><br/><p><img src="https://www.thephysiqueprotocol.com/cdn/shop/files/92_10620741-fd6d-487e-89a0-940d9f028b8c_1600x.jpg?v%5Cu003d1724945758">The space shuttle flight path. Mouse over the boxes to see the stages. A typical shuttle mission lasts seven to eight days, but can extend to as much as 14 days depending upon the objectives of the mission. Let's look at the stages of a mission one by one. The Hubble Space Telescope uses a system of cameras and mirrors to detect distant star light. Let's look at these components closely. In addition, the SRBs support the entire weight of the space shuttle orbiter and <a href="https://www.dict.cc/?s=fuel%20tank">fuel tank</a> on the launch pad. Because the SRBs are solid rocket engines, once they are ignited, they cannot be shut down. Therefore, they are the last component to light at launch. The orbiter has three main engines located in the aft (back) fuselage (body of the spacecraft). Each engine is 14 feet (4.3 m) long, 7.5 feet (2. 3 m) in diameter at its widest point (the nozzle) and weighs about 6,700 lb (3039 kg).</p><a href="https://www.gap-group.co.uk/products/lifting/manual-powered-lifting"><img src="https://yewtu.be/sSZ4Jm8t9n8"></a><br/><br/><div style="clear:both;"></div><p>The main engines provide the remainder of the thrust (29 percent) to lift the shuttle off the pad and into orbit. The engines burn liquid hydrogen and liquid oxygen, which are stored in the external fuel tank (ET), at a ratio of 6:1. They draw liquid hydrogen and oxygen from the ET at an amazing rate, equivalent to emptying a family swimming pool every 10 seconds! The fuel is partially burned in a pre-chamber to produce high pressure, hot gases that drive the turbo-pumps (fuel pumps). The fuel is then fully burned in the main combustion chamber and the exhaust gases (water vapor) leave the nozzle at approximately 6,000 mph (10,000 km/h). Each engine can generate between 375,000 and 470,000 lb (1,668,083 to 2,090,664 N) of thrust; the rate of thrust can be controlled from 65 percent to 109 percent maximum thrust.
