Shuttle-derived vehicle

[1] In the late 1980s and early 1990s, NASA formally studied a cargo-only vehicle, Shuttle-C, that would have supplemented the crewed Space Shuttle.

[4] After the earlier programs were cancelled, NASA began development of the Space Launch System (SLS) in 2011.

[6] The Shuttle-C was a study by NASA to turn the Space Shuttle launch stack into a dedicated uncrewed cargo launcher.

[9] Shortly thereafter, NASA asked Lockheed Missiles and Space, McDonnell Douglas, and TRW to perform a ten-month study.

[11][12] The NLS-1 was the largest of three proposed vehicles and would have used a modified Space Shuttle external tank for its core stage.

[13][14] One of the main goals of Constellation program was the development of spacecraft and booster vehicles to replace the Space Shuttle.

[20] However, the Constellation program, including Ares I was cancelled by U.S. president Barack Obama in October 2010 with the passage of his 2010 NASA authorization bill.

[18] The Ares V was to launch the Earth Departure Stage and Altair lunar lander for NASA's return to the Moon, which was planned for 2019.

[20] However, the Constellation program, including Ares V was cancelled by U.S. president Barack Obama in October 2010 with the passage of his 2010 NASA authorization bill.

[24] NASA had considered using Ares IV to evaluate high-speed "skip" reentry profiles of the Orion capsule in 2007.

[26] Ares V Lite was an alternative launch vehicle for NASA's Constellation program suggested by the Augustine Commission.

[30] Based on the Shuttle-C concept which has been the subject of various studies since the 1980s, the HLV was a SDLV that proposed to replace the winged Orbiter from the Space Shuttle stack with a side-mounted payload carrier.

[37] Liberty was a 2011 launch vehicle concept proposed by Alliant Techsystems (ATK) and Astrium for phase 2 of the NASA Commercial Crew Development (CCDev) program intended to stimulate development of privately operated crew vehicles to low Earth orbit.
