Haas is a family of rocket space launchers developed by the Aeronautics and Cosmonautics Romanian Association (ARCA) for the Google Lunar X Prize competition and for their national manned space program. It consists of Haas balloon-launched orbital rocket, Haas 2 airplane-launched orbital rocket, Haas 2b ground-launched suborbital rocket and Super Haas ground-launched orbital rocket. It was named after Conrad Haas, a medieval rocket pioneer who lived and worked in what is now Romania, and was the first person to describe a multistage rocket in writing.〔 == Haas == Haas was a Romanian carrier rocket, which was developed by ARCA as part of the ELE programme. It was designed to be air-launched from a high-altitude balloon, similar to the American Rockoon experiments of the 1950s. Prior to the development of Haas, ARCA had already launched two Stabilo rockets from balloons. It is fueled by hydrogen peroxide and bitumen. The Haas rocket〔ARCA Space, (Haas Orbital Rocket Launcher ) fact sheet, Dec. 2, 2008 (accessed 22 Sept 2014)〕 was to be a three-stage rocket intended to be capable of placing 400 kilograms of payload into low Earth orbit. Its maiden flight was to carry the European Lunar Explorer spacecraft, ARCA's entry into the Google Lunar X-Prize, following a series of engine tests which began in 2009. It was abandoned when ARCA decided to stop using solar and helium balloons for their space program. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Haas (rocket)」の詳細全文を読む スポンサード リンク
