The satellites following Tiros M were given ITOS designations, the first being ITOS A. By the time ITOS A was launched, by Delta from Vandenberg at 1130 on 1970 Dec 11, ESSA had become NOAA and so instead of being ESSA 10 the satellite was renamed NOAA 1 on reaching orbit. NOAA 1 operated in a 114.9 min, 1429 x 1479 km x 101.9 deg orbit until 1971 Aug 19 when its attitude control failed.

ECS-1

1983-058A

The ECS 1 (European Communications Satellite 1) was built for ESA by the British Aerospace BAe/MESH consortium, based on the OTS/MARECS bus.

In 1983 Oct ownership of ECS 1 was transferred from ESA to the European Telecommunications Satellite Organization (EUTELSAT) and it was later renamed Eutelsat I F-1.

In Sep 1984, ECS 1 suffered a partial power loss due to short circuits in the solar panels.

In 1993 it was planned to move F1 from 25.5E to 36E to improve Central Asian communications.

Luna 1960

1960-U01

The next E-2A type probe was given an improved radio system and redesignated called E-3; it replaced a proposed E-2F mission which would have had a Yenisey-3 camera. They were intended as Luna-3-like photographic circumlunar flights. They had a simpler design, using the E-2A pressure container but with a single 750mm focal length camera. The first E-3 probe was launched on 1960 Apr 15. The Blok-E stage cut off too early and E-3 No. 1 carried out a high apogee suborbital flight, velocity 110 m/s (or 130 m/s) too low. This was the first failure of the Blok-E.

Salyut 2

1973-017A

The first Almaz orbital piloted station (OPS 1, 11F71 No. 101) was launched on 1973 Apr 3. To hide the existence of the military Almaz program, it was given the same Salyut cover name as the civilian DOS stations, becoming Salyut-2 on reaching orbit.

17 debris objects were cataloged shortly after launch and it appears that the third stage of the Proton launch vehicle disintegrated shortly after OPS 1 separated. Failure to vent the stage led to overpressurization of the rocket body and explosion. The debris objects reentered over a 27 day period. OPS 1 raised its orbit on Apr 4 to 240 x 259 km, similar to DOS 1's operational orbit. On Apr 6 three more debris objects were tracked, reentering quickly over the next 4 days.

On Apr 8 the orbit was raised again to 261 x 284 km; then on Apr 14 it appears that the station was depressurized and possibly entered a spin - three new, large debris objects were tracked, possibly the solar panels; two of them (17Z and 17AA) remained in orbit for another month. On Apr 28 it was announced that the mission had been completed. By May 27 the altitude of the station had decayed to only 160 km and the next day it made an uncontrolled reentry.
