Terrier Malemute

The Terrier Malemute is a two-stage American sounding rocket typically used for smaller payloads (less than 180 kg [400 lb]).

The first stage booster consists of a surplus Navy Terrier MK 12 Mod 1 rocket motor with four 0.22 m2 (340 sq in) fin panels arranged in a cruciform configuration.

[3] For a payload weight of 200 lb (91 kg), the acceleration during the boost phase is 26 g.[4] Its first flight was on November 11, 1974, from Barking Sands.

[8] On 26 November 2019, a Terrier Improved Malemute suborbital sounding rocket was launched from Ny-Ålesund, Norway.

The suborbital flight, with an apogee of 252 km (157 mi), was a partial failure as the rocket experienced a roll rate anomaly, precluding the on board instruments from functioning as intended.
