STS-51-F (Challenger)

 1985-063A

---

The first attempt to launch 51-F, at 2030 on 1985 Jul 12, ended in an RSLS abort at T-3s. The next attempt was on Jul 29; Challenger left the pad at 2100, but at 2105 the first SSME was automatically shut down - because of an incorrect sensor reading, it later transpired - and the CapCom could be heard calling to the Orbiter in a decisive tone "Abort! Abort ATO!". "Roger - Abort ATO", came the reply, and the first in-flight abort got underway. The ATO (Abort To Orbit) was the most benign type, and consisted of continuing to a lower than planned orbit on the two remaining engines. The OMS engines were ignited and used 1875 kg of OMS propellant to increase the final velocity.

The ET landed at 48.9S 159.1E instead of 33.6S 159.9W., in the same general area of the South Pacific but over 1500 km south of the target.

On Jul 30 at 2328 the RMS arm raised the PDP subsatellite above the payload bay, to make measurements of the plasma around the Shuttle. Inbetween active series of measurements, it was parked over the port wing from 0835 to 1840 on Jul 31, and again from 1928 to 2023. At 0010 on Aug 1, PDP was released into free flight as the Shuttle maneuvered around it in a test of the far field plasma properties of the Shuttle wake. The RMS arm recaptured the PDP at 0620 and observations with it attached to the arm continued until it was latched in the bay late on Aug 2. On Aug 5 the OMS 7 burn was used in a plasma depletion test to study the effects on the near-Shuttle plasma of a rocket burn. PDP was finally deactivated on Aug 6 at 0528, and Challenger landed without incident sixteen hours later.

Saturn SA-6

  1964-025A

---

SA-6 carried the first boilerplate (dummy) Apollo CSM spaceship, Apollo BP-13, as A-101. A `service module insert' cylinder and an adapter cylinder 3.91m dia 3.66m long connected BP-13 to the Saturn SIV stage. Launch was at 1707 on 1964 May 28; engine 8 cut off prematurely but the second stage compensated. The Saturn S-4-6 stage entered a 179 x 204 km x 31.74 deg orbit. Apollo BP-13 remained attached to the S-IV stage above S-IU-6. The mission was designated Apollo-Saturn 101 (AS-101). SA-6 transmitted for 4 revs and reentered on Jun 1 at around 0030.

NOAA 2

  1972-082A

ITOS D (NOAA 2) carried an improved set of infrared imaging and atmospheric sounding instruments. It was launched at 1719 on 1972 Oct 15 from Space Launch Complex 2-West at Vandenberg. The Castor motors separated from the Delta 0300 rocket at 1721; at T+3:40 the Thor stage separated and the Delta second stage began its 5 min burn. At 1728 the Delta and NOAA 2, still attached, were in parking orbit. At 1816 Delta reignited for 12 seconds to insert the combination into sun-synchronous orbit, and NOAA 2 separated into a 115.0 min, 1451 x 1458 km x 101.8 deg orbit at 1823. The Oscar subsatellite separated from the Delta at 1825 and at 1903 the Delta made a test burn to a 918 x 1475 km x 102.8 deg orbit. NOAA 2 sent back weather data until 1975 Jan 10.

Comstar 1

  1976-042A

---

The Comstar 1 satellite was an Intelsat 4A class C-band communications satellite intended for use by AT&T; for US domestic communications. It was originally owned by Comsat General Corp. and leased to AT&T.; AT&T; took ownership in 1985 of the Comstars, but by that time Comstar 1 was retired. Comsat General control was in Washington DC, with ground stations at Southbury, Connecticut and Santa Paula, California.

STS-72 (Endeavour)

 1996-001A

---

The first launch of 1996 was carried out with less publicity than usual because of continuing effects of the government shutdown. Endeavour took off at night, in an unusual launch profile which avoided the need for a single engine TAL abort mode (RTLS and Press to ATO covering the entire ascent). It entered an elliptical 66 x 455 km orbit, and a smaller than usual OMS 2 burn raised the perigee to 180 km.

The EDFT-3 spacewalks made use of an array of ISS EVA equipment stowed in the forward bays. DTO 671 was to evaluate ISS EVAs; DTO 672 tested the electronic cuff checklist, and DTO 833 studied the thermal properties of the improved EMU suit; DTO 1210 covered EVA operations and training. During EVA-1, Chiao and Barray tested the portable work platform and the Rigid Umbilical, as well as foot retsraints. On EVA-2 they practised with connectors and a slidewire, and did force measurements with CLAS, installing the PDAP.

JAWSAT

 2000-004A

---

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?
