JAWSAT is the Joint Academy-Weber State Satellite. It is amateur satellite Weber Oscar-39 (WO-39). [223] The Weber State (One Stop Satellite Solutions/Ogden) built 64 kg microsat flew on an MSLS (Minuteman) launch vehicle in Jan 2000 under the Orbital-Suborbital Program (OSP). It was built for educational purposes, but will carry some experiments. Originally part of STP, as Space Test Program mission P98-1, it was converted after STP withdrew into a simple Multi-Payload Adapter (MPA).
The orbital MSLS vehicle is called the Minotaur [224] It has the Minuteman 2 stages 1 and 2 with two Pegasus upper stages,. Launch from California Spaceport in S Vandenberg.
The Minotaur has an M55A1 stage 1, an SR-19 stage 2, an Alliant Orion 50XL stage 3, and an Orion 38 stage 4, with a Pegasus fairing. Pegasus fairing is 4.4m long 1.3m dia.
M55A1 is 7.5m long 1.67m dia, 20788 kg prop, 23081 kg full, steel case, TP-H1011 prop. Thrust is 80.7 kN, isp 237s, 60s burn. SR19 is 4.1m long 1.33m dia, 6238 kg prop, 7033 kg full, Ti case, ANB-3066 prop. Thrust is 27 kN, isp 287.5s, 65s burn. Orion 50XL is 3.6m l 1.28m dia, 3915 kg prop, 4332 kgf, GE case, HTPB. Thrust is 15 kN, isp 290.1s, 72s burn. Orion 38 is 1.3ml 1.0m dia, 771 kgp, 897 kgf, GE case, HTPB. Thrust 32 kN, isp 290.2s, 69s burn. (or: 900f 223 em)
JAWSAT consists of the MPA (MultiPayloadAdapter) spaceframe. The PEST and ACP experiments are attached to it, and four subsatellites are ejected. JAWSAT separated from the SRSS (Soft Ride System, 14 kg) and the final stage.
The spacecraft seems to have failed soon after deploying OPAL and OCSE.
Orbit is 700 km polar x 98.4 deg.
The Orbital/Suborbital Program Space Launch Vehicle (OSPSLV) Minotaur launched from the Spaceport Systems International Commercial Launch Facility (California Spaceport.)
The total payload was 126 kg. m1/m2 = 1026 / 349 so dV = 2846 ln m1/m2 = 3069 m/s. Actual burn 2584 m/s?
