Kosmos 1896

 1987-093A

---

Kosmos-1896, spacecraft 8, was probably the first flight after Siluet was accepted into armaments and became Kometa. It landed on Dec 25; based on the landing times of later missions, I assume the 2048 UTC opportunity was used.

EURECA

 1992-049B

---

ESA's European Retrievable Carrier (EURECA) was built by MBB-ERNO (later DASA-ERNO). The 4491 kg spacecraft was 4.5m by 2.54m in size, with a retractable 20m x 3.5m solar array. It was deployed from Atlantis in Aug 1992 and used its on-board engine to raise its orbit over the next few days to 501 x 506 km. In late May 1993 it lowered its orbit again to 474 x 482 km and in June it was recovered by Endeavour on mission STS-57, and brought back to Earth.

Venera 8

  1972-021A

V-72 No. 670 was the final Venera probe based on the OKB-1 design. It was launched to Venus in Mar 1972. The capsule landed on Venus on Jul 22 at 0929 UTC; the parachute container impacted separately and the antenna cover separated. The probe transmitted from the surface for 50 minutes.
