Minotaur

Minotaur C

The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government. The first and second stages, taken directly from decommissioned Minuteman missiles, are mated to the Orion third and fourth stages taken from the Pegasus XL air-launched rocket family. An optional hydrazine-powered fifth stage called HAPS can be used.The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government.

The Minotaur IV launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. A fourth stage, the Orion-38, is taken from the Pegasus family of air-launched rockets.

Minotaur IV

The Minotaur IV HAPS launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. A fourth stage, the Orion-38, is taken from the Pegasus family of air-launched rockets. A fifth stage, consisting of a hydrazine-powered motor called HAPS, increases orbital insertion accuracy and allows additional orbital maneuvering.

Minotaur IV HAPS

The Minotaur IV+ launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. It is similar to the Minotaur IV, but uses a larger Star-48V upper stage in place of the Orion-38 used on the baseline Minotaur IV.

ミノタウロス IV+ はピースキーパー ICBM から派生した打ち上げシステム。第 1〜3 段は退役したピースキーパーミサイルのものをそのまま使う。ミノタウロス IV に似ているが、基本型のオリオン 38 の代わりに大型の上段スター 48V を使う。

Minotaur IV+

Minotaur V

American all-solid orbital launch vehicle based on a Pegasus and Peacekeeper rocket.It has been designed as a quick reaction launch vehicle, which can be launched from minimaly prepared places in a matter of a few days.

ペガサスとピースキーパーを基にした米国の全段固体の軌道打ち上げ機。最小限の準備をした場所から数日で打ち上げられる即応型打ち上げ機として設計された。

STP-S29A is a mission under the U.S. Department of Defense's Space Test Program (STP) that will deliver technology demonstrations to orbit and contribute to future space system development, with this launch delivering up to 200 kg of STP cubesats to Low Earth Orbit.

The main payload will be STPSat-7, an ESPA class satellite based on the Aegis Aerospace M-1 satellite bus used on the STPSat-4 mission for hosting research and technology demonstration payloads for the Department of Defense (DoD). One of the payload is U.S. Naval Research Laboratory's (NRL) Lightsheet Anomaly Resolution and Debris Observation (LARADO) instrument, used to detect and characterize lethal non-trackable orbital debris with lasers in orbit.
