List of space launch system designs covers designs and concepts for rockets and other vehicles for sending payloads into space. This is a list of plans, concepts, and/or proposals for launch systems such as rockets and reusable spaceplanes, typically for orbiting the Earth. Plans may mature into an actual launch system, or may not be developed. An example of launch vehicle plan, is the Space Launch System proposed by NASA in 2011, which is planning to be developed and tested over the next two decades. ==21st century== *ESA Future Launchers Preparatory Programme () :Space Launch Initiative designs ()〔(【引用サイトリンク】publisher=NASA )〕 *Reaction Engines Skylon SSTO HTHL (current) :A development of the HOTOL concept for an autonomous spaceplane *Kistler K-1 TSTO () *Shuttle-Derived Heavy Lift Launch Vehicle () :Side-mount, a non-reusable, cargo-oriented Shuttle-based launch vehicle with payload capacity (100/35/75) tons for the heaviest variant, the lunar-capable vehicle (different versions with payload capacities 66, 68, 71, 81, 83 tons to LEO were also considered ). The vehicle is also known as Shuttle-Derived Heavy Lift Launch Vehicle, High Confidence Heavy Lift Launch Vehicle, and HLV. In a picture shown at the 17 June 2009 meeting of the Review of U.S. Human Space Flight Plans Committee in Washington DC, NASA Space Shuttle Program Manager John Shannon introduced a High Confidence Heavy Lift Launch Vehicle capable of putting 104 metric tonnes to LEO.〔 *DIRECT proposals (2000s - current) :Direct's Jupiter-rocket designs studied under the DIRECT 3.0-program (started in 2006) include many versions, such as Jupiter-130 and Jupiter-246, with claimed lift capacities exceeding 60 and 90 tonnes to LEO (up to 100 tonnes with Jupiter-upper stage, and 120 with five-segment solid rocket boosters and upper stage) and the in-line-version (110/35/75). Also older, DIRECT 2.0-program versions of Jupiter, like Jupiter-120 and Jupiter-232, exist.〔 *Constellation Ares I, IV, V designs () * *Ares IV (40mt TLI) as part of the Constellation Program of 2005. * *Ares V Lite (140/55/120)〔 *Liberty TSTO (2000s - current) :A rocket with to ISS orbit. The rocket consists of Alliant Techsystems Stage I (Ares I) and EADS Astrium Stage II (Ariane 5). It will cost less than $180M〔 or less than $8,899/kg〔 *Space Launch System () :A NASA Space Shuttle-based launch system designed to replace the Shuttle after its retirement. This is the NASA's current plan to replace the Shuttle (authorized by NASA Authorization Act of 2010). The systems payload capacity to LEO should be 64-130 tons depending heavily on the launch configuration. *Stratolaunch Systems ()〔(DONNA BLANKINSHIP and SETH BORENSTEIN - Allen, Rutan Plan Huge Plane to Launch Spaceships (2011) - ABC News )〕 :Jet carrier aircraft launches large rocket in the air.〔 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「List of space launch system designs」の詳細全文を読む スポンサード リンク
