Minotaur Vis an Americanexpendable launch systemderived from theMinotaur IV,itself a derivative of theLGM-118 PeacekeeperICBM.It was developed byOrbital Sciences Corporation,(now absorbed intoNorthrop Grumman Innovation Systems) and made its maiden flight on 7 September 2013 carrying theLunar Atmosphere and Dust Environment Explorerspacecraft forNASA.[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 ageosynchronous transfer orbit,or 342 kilograms (754 lb) on atrans-lunartrajectory.[3]It consists of a Minotaur IV+, with aStar-37as a fifth stage. Two variants are available, one with aspin-stabilizedStar-37FM upper stage, and the other with a Star-37FMV capable ofthree-axis stabilization.[3]The Star-37FMV upper stage is heavier, reducing payload capacity, but is more maneuverable.

Launch pads[edit]

Space Launch Complex 8at theVandenberg Space Force Base,Pad 0Bat theMid-Atlantic Regional Spaceport(MARS), andPad 1of theKodiak Launch Complexare all capable of accommodating Minotaur V. As of 2024,the vehicle has only launched from MARS.[4]

Launch history[edit]

The only Minotaur V occurred on 7 September 2013 at 03:27 UTC fromLaunch Pad 0Bat theMid-Atlantic Regional Spaceportin Virginia. The payload for the maiden flight was theLADEElunarexoatmosphere 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 becamederelict satellitesinEarth orbit(SATCAT: 39248, decay date: 27 November 2013).[6]
