Buran with Booster - ADP Master Model 1/288 made by Bianca Krop-Kaiser

Das sowjetische Buran-Raumfahrtprogramm (russisch Буран für Buran – Schneesturm, Betonung auf der zweiten Silbe) begann 1976 am ZAGI als Antwort auf das US-amerikanische Space Shuttle. Der Name leitet sich aus dem Namen der ersten Raumfähre Buran 1.01 (Schneesturm) ab, wird aber auch für das gesamte sowjetische Raumfährenprogramm verwendet. Das Projekt war das größte und teuerste Einzelprojekt in der sowjetischen Raumfahrt. Es kam aus finanziellen Gründen nur zu einem einzigen unbemannten Einsatz. Zeitweise arbeiteten bis zu 30.000 Menschen an dem Projekt. Die Raumfähre wurde, ebenso wie die für den Start benötigte Trägerrakete Energija, vom OKB-1 Koroljow (Experimental-Konstruktionsbüro-1, heute RKK Energija) und NPO Molnija entwickelt unter Leitung von Walentin Gluschko (Energija, Gesamtprojekt) und Gleb Losino-Losinski (Buran). Das Buran-Programm wurde 1993 offiziell eingestellt.
Der Buran-Orbiter ähnelt äußerlich dem Space Shuttle, da veröffentlichte Rißzeichnungen den Russen als Vorlage dienten, weist aber eine Reihe konzeptioneller Unterschiede auf.

Space Shuttle Columbia - Revell 1/144 built by Bianca Krop-Kaiser

The Space Shuttle was a crewed, partially reusable low Earth orbital spacecraft operated by the U.S. National Aeronautics and Space Administration (NASA). Its official program name was Space Transportation System, taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. It was used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST); conducted science experiments in orbit; and participated in construction and servicing of the International Space Station.
Shuttle components included the Orbiter Vehicle (OV), a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen. The Shuttle was launched vertically like a conventional rocket, with the two SRBs operating in parallel with the OV's three main engines, which were fueled from the ET. The SRBs were jettisoned before the vehicle reached orbit, and the ET was jettisoned just before orbit insertion using the orbiter's two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to drop out of orbit and re-enter the atmosphere. The orbiter glided to a runway landing on Rogers Dry Lake at Edwards Air Force Base in California or at the Shuttle Landing Facility at the KSC. After the landings at Edwards, the orbiter was flown back to KSC on the Shuttle Carrier Aircraft, a specially modified Boeing 747.
The first orbiter, Enterprise, was built purely for Approach and Landing Tests and had no capability to fly into orbit. Four fully operational orbiters were initially built: Columbia, Challenger, Discovery, and Atlantis. Of these, Challenger and Columbia were destroyed in mission accidents in 1986 and 2003, respectively, in which a total of fourteen astronauts were killed. A fifth operational orbiter, Endeavour, was built in 1991 to replace Challenger. The Space Shuttle was retired from service upon the conclusion of Atlantis' final flight on July 21, 2011.
