Space Shuttle "DISCOVERY"with Booster

NASA’nın gelistirdigi yeniden kullanılabilen uzay mekigi projesi 1972 yılında basladı. Toplam agırlıgı 2055 ton olan “Discovery” mekiginin 30 tonluk tasıma kapasitesi vardı. 1976’da yapılan ilk yörünge aracı prototipi “Enterprise” yörüngedeki uçus ve inis karakteristiklerini arastırmak amaçlı yapıldı. 1981’de ilk uzay mekigi “Columbia” fırlatıldı, 1983’te “Challenger” , 1984’te “Discovery”, 1985’te “Atlantis”, 1992’de “Endeavour” fırlatılarak 26 görev tamamlandı. Uzay yörünge araçları yörüngede en fazla 28 gün kalabilmektedir. Inis esnasındaki sürtünmeden kaynaklı olusan yüksek ısı yörünge araçlarının alt kaplamasında hasar yaratıyor ve her sefer sonrasında tekrar yenilenmesi gerekiyordu. 1986’da “Challenger”, 2003’te “Columbia” kazalarından sonra verilen iki yıllık arada yapılan gelistirmelerden sonra görevlere devam edildi. 2005 yılında inis yapan “Discovery” kendisinin 31. NASA’nın 114. görevini tamamlamıstır. Daha sonra “ISS” projesini yürütmek için görevlere devam edilmistir.
 
 
The development of a transport system for NASA, reusable in its main components, began in 1972. The total weight of the Space Shuttle ready for launch is 2,055 t. It can carry a payload of 30 tonnes to an orbit up to 965 km above Earth. The orbiter prototype, the “Enterprise” , was completed in 1976. The Enterprise was used to research flight and landing characteristics in the atmosphere and in the development of the space-qualified shuttle. The first launch of a space shuttle into space then occurred on April 12, 1981, with the space shuttle “Columbia”. “Challenger” was in space for the first time on April 4, 1983. “Discovery” lifted off for the first time on August 30, 1984. Since 1985, the fourth space shuttle, “Atlantis”, has been on 26 missions. “Endeavour” completed its first launch on 1992. This shuttle was equipped with numerous new devices and computers, making it more powerful overall. The orbiters can remain in space for a maximum of 28 days. The enormous structural and thermal stresses during launch and landing require constant checks and maintenance of all components, as well as equipment improvements. The heat shield on the front and underside of the space shuttle is particularly affected by this and must be constantly monitored and repaired. Two tragic accidents that killed the entire crew resulted in the loss of “Challenger” in 1986 and “Columbia” in 2003. After a two-year hiatus and extensive modifications to the orbiters and main tank, flights resumed. With its landing at Edwards Air Force Base in California on August 9, 2005, Discovery's 31st flight and NASA's 114th Space Shuttle mission were successfully completed. With the resumption of shuttle flights, the expansion of the International Space Station “ISS” will continue in the coming years.
