Kosmos 382

  1970-103A

---

The second L-1E test flight was 7K-L1E No. 2, launched in Dec 1970 as Kosmos-382. It may have carried a supplementary ion engine experiment since the orbital eccentricity was observed to change slowly up to Feb 1971.

Several objects were cataloged in orbit with Kosmos-382. Objects E, F and G were ejected into the 160 minute orbit prior to burn 3. They were tracked later in high apogee orbits which continued to become more eccentric, and were presumably being affected by radiation pressure.

Objects B and C are believed to be the SOZ motors; they were ejected into the 160 minute orbit around the time of burn 3.

Object D was released after burn 3 into the final orbit, but was strongly affected by radiation pressure and decay and has a low RCS. It may be an insulation panel of some kind.

Three in-orbit burns had 982, 285 and 1311 m/s. There were seven burns in total.
