The rocket on sale is one of eight that were built as part of a US$95 million partnership between NASA and the Russian Institute for New Propellants (CIAM). The program sought to develop a hypersonic machine using pioneering propulsion technology.
The resulting Kholod rockets, or "scramjets," were fueled by cryogenically cooled liquid hydrogen and were capable of traveling at Mach 6.47 (4,310 mph / 6,936 km/h). According to RM Auctions, the first Kholod rocket was tested in Kazakhstan in November 1991, reaching an altitude of 35 km (22 mi).
Over the next 10 years, the Kholod was the world record holder for outright atmospheric speed and it is still the fastest machine to have traveled within Earth’s atmosphere.
A total of nine Kholod rockets were produced, of which five were destroyed during tests. Of the remaining four which returned to Earth, only three remain in existence. This is the first time that a Kholod rocket has been made available to the public to buy.
The Kholod will be auctioned alongside a number of cars on September 8th.
