Westar 5

 1982-058A

---

Western Union Spacecom's Westar V HS-376 class satellite was launched in 1982 to replace the aged Westar II. The first stage burn was short by 91 m/s, but the second stage overburned to compensate.

Saturn S-IVB-504N

  1969-018B

---

SA-504 was launched at 1600:00 on 1969 Mar 3. The S-IVB entered earth orbit at 1611:15, and Apollo 9 separated from it at 2018. The S-IVB restarted at 2045:47, entering a 207 x 3087 km x 32.6 deg orbit. A third burn at 2207:19 sent the stage on an escape trajectory to solar orbit. The burn involved an experimental extended preburn fuel supply, and several anomalies were reported; pressurization was lost in the engine system, losing about 2 km/s of velocity. At MECO-3 the velocity was 9.628 km/s at an altitude of 2283 km, and C3 was 824712 m²/s². The S-IVB reached a 325.8d, 128.561 x 148.678 Mkm x 24.39 deg solar orbit instead of the planned 240d, 76.808 x 149.340 Mkm x 22.27 deg orbit.

Apollo 9 (Spider)

  1969-018C

---

LM 3 was the first piloted test flight of an LM, carried out in Earth orbit.

On Mar 6 the first spacewalk of the Apollo program was carried out. With Scott in the CSM, and McDivitt and Schweickart in the LM, the LM hatch was opened. Schweickart went out onto the LM porch. The spacecraft was repressurized after 1h 7min.

On Mar 7, Spider undocked and carried out tests of the DPS engine. After two burns of the DPS, the Descent Stage was jettisioned; it reentered on Mar 22. The APS was then put through its paces, with a successful rendezvous and docking. After the crew returned to the CSM, Spider was jettisoned and the APS burned again to leave the ship in an elliptical orbit.

Kosmos 469

 1971-117A

---

A US-A satellite was launched in Dec 1971 from Baikonur,reached orbit and was named Kosmos-469. It operated in the low orbit for ten days before the reactor section was separated and boosted to a higher orbit. One solution for the orbit change is with burns at 0637, 0729 UTC on Jan 4; this is consistent with the claimed time of orbit change in the RAE tables. However, a pair of elsets for the separate reactor and propulsion sections for epoch around 0300 UTC suggests that separation took place before that time. I therefore adopt another solution with burns at 2013 and 2105 UTC on Jan 3.

ADEOS-1

 1996-046A

---

The ADEOS satellite was launched in Aug 1996. NASDA's ADEOS Advanced Earth Observing Satellite was built by Mitsubishi Electric of Tokyo. The 3200 kg satellite has a 4m x 4m x 5m bus with a 3 x 13 m solar array. It carries a payload to study the ozone layer and the greenhouse effect, as well as an inter-satellite communications experiment. The satellite was named Midori (`green') on reaching orbit, but the ADEOS name was almost always used.

The main 20N thrusters malfunctioned, and initial orbit adjust was made by the small 1-N thrusters. In June 1997 the solar panels failed structurally and the spacecraft was lost.

Kosmos 1074

 1979-008A

---

Kosmos-1074 (7K-ST No. 5L) spent 60 days in space to simulate a long duration Soyuz T mission. The mission had been planned for 90 days, but it was cut short because of a control system failure.

A post reentry TLE set is probably for the orbital module, which is probably cataloged as 11315 (79-008C). Its first assigned elsets are at 1343 UTC on Mar 31, a day before reentry - it is possible that the BO was ejected early as a test or that a planned recovery on Mar 31 was aborted

IRS-P3

 1996-017A

---

IRS-P3 was launched by PSLV in Mar 1996. Mass of the satellite was 922 kg. As well as the remote sensing instruments, it carried an X-ray astronomy payload. Three proportional counters studied variable X-ray sources in the 2-18 keV band. The first reported results  were measurements of the X-ray pulsar GX1+4 and the superluminal transient GRS 1915+105.
