The final FB-1 launch carried Shi Jian 2 (Shi Jian Er Hao, PRC 9) into orbit. The satellite was also referred to as Shiyan Kexuedi Weixing (Experimental Scientific Satellite) but the SJ-2 name has been consistently used since the late 1980s. Two small subsatellites were carried into orbit with SJ-2. SJ-2 was an octagonal cylinder with 4 solar panels, 1.1m long and 1.2m diameter.

STEP Mission 2 (STP P91-2) was launched by a Pegasus from the Point Arguello Warning Area over the Western Test Range. The B-52 air-launched the Pegasus after takeoff from Edwards AFB. The Pegasus had a fourth hydrazine stage, the HAPS, and was intended to place STEP 2 into an 830 km polar orbit; the orbit achieved was only 603 x 821 km. The HAPS stage shut down early due to a software error.

STEP 2's main payload was SIDEX, the USAF Rome Lab signal identification experiment, intended to pick out specific signals from regions of high communications background. The 180 kg satellite was a TRW/DSI Eagle class lightsat.

Saturn S-IVB-504N

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.
