The Minotaur V is an American expendable launch system derived from the Minotaur IV, itself a derivative of the LGM-118 Peacekeeper ICBM. It was developed by Orbital Sciences Corporation, and made its maiden flight on 7 September 2013 carrying the LADEE spacecraft for NASA.[2]

Design[edit]

The Minotaur V is a five-stage vehicle, and is designed to place up to 630 kilograms (1,390 lb) of payload into a geosynchronous transfer orbit, or 342 kilograms (754 lb) on a trans-lunar trajectory.[3] It consists of a Minotaur IV+, with a Star-37 as a fifth stage. Two variants are available, one with a spin-stabilized Star-37FM upper stage, and the other with a Star-37FMV capable of three-axis stabilization.[3] The Star-37FMV upper stage is heavier, reducing payload capacity, but is more maneuverable.

Launch pads[edit]

Space Launch Complex 8 at the Vandenberg Air Force Base, Pad 0B at the Mid-Atlantic Regional Spaceport (MARS), and Pad 1 of the Kodiak Launch Complex are all capable of accommodating the Minotaur V. As of 2013, all scheduled launches are from MARS.[4]

Launch history[edit]

The initial launch of a Minotaur V occurred on 7 September 2013 at 03:27 UTC from Launch Pad 0B at the Mid-Atlantic Regional Spaceport in Virginia. The payload for the maiden flight was the LADEE lunar exoatmosphere science spacecraft.[5] While now separated from the LADEE spacecraft, both the fourth and fifth stages of the Minotaur V reached orbit, and are now derelict satellites in Earth orbit.[6]
