Minotaur V is an American expendable launch system derived from the Minotaur IV, itself a derivative of the LGM-118 Peacekeeper, an intercontinental ballistic missile. It was developed by Orbital Sciences Corporation, (now absorbed into Northrop Grumman) and made its maiden, and to date, only flight on 7 September 2013 carrying the LADEE (Lunar Atmosphere and Dust Environment Explorer) spacecraft for NASA.[2] While Minotaur V is still likely active and available to fly, no further flights are scheduled as of May 2024.
Design
[edit]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 Space Force Base, Pad 0B at the Mid-Atlantic Regional Spaceport (MARS), and Pad 1 of the Kodiak Launch Complex are all capable of accommodating Minotaur V. As of 2024[update], the vehicle has only launched from MARS.[4]
Launch history
[edit]The only Minotaur V launch 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 (SATCAT: 39246, decay date: 18 April 2014).[5] While now separated from the LADEE spacecraft, both the fourth and fifth stages of the Minotaur V reached orbit, and became derelict satellites in Earth orbit (SATCAT: 39248, decay date: 27 November 2013).[6]
