Nadezhda 6

 2000-033A


The Nadezhda satellite launched in Jun 2000 was the first Plesetsk launch to sun-synchronous orbit. It may have carried only the COSPAS-9 payload and omitted the nav payload, according to some reports.

  1976-114A


Another year passed before 11F732 No. 3L (7K-S No. 3L) was launched. This time the ship remained in orbit for 18 days, maneuvering extensively. It went out of control for two days with loss of communications and an IR horizon sensor failure and the planned 8 day flight was extended to include all the planned test objectives. The spacecraft landed successfully.

NEAR Shoemaker

 1996-008A


The first Discovery probe was NEAR, the Near Earth Asteroid Rendezvous. It was built and operated by JHU-APL. The box-shaped satellite had 4 fixed (but hinged) solar panels and no extensible booms to save money; the science instruments were in the base of the bus. An Aerojet propulsion system included a 100lb LEROS 1 thruster. Launch mass was 805 kg full, 468 kg dry, 337 kg prop. (816 full 475 kg dry per APLTD19-2-157, APLTD23-1-73). The propulsion system mass was 438 kg. The vehicle is a box 2.80m tall and 1.47m in diameter with four deployable solar panels attached to the upper edge and a 1.5m high gain antenna. The despin cables are around 12m long.

NEAR was launched by a Delta into a hyperbolic trajectory with C3 = 26 (km/s)2.

NEAR flew past (253) Mathilde in 1997. Mathilde was the first C-type asteroid to be visited and was found to have a diameter of 52 km. Flyby speed was 10 km/s.

In Dec 1998, the biggest burn to date was planned: a 650 m/s burn of the main engine. A 3-minute fuel settling burn was successful, but then 0.2s after ignition for the main burn the engine aborted with only 0.2m/s of velocity change. The failure resulted in a 1 km/s flyby of Eros. A burn on 1999 Jan 3 placed NEAR in a rendezvous orbit with a maximum distance of 1 million km, with re-rendezvous on 2000 Feb at 0.04 km/s. Orbit insertion was successful on Valentine's Day 2000. Eros has a mass of around 7 teratonnes and a 50 km radius orbit around it has a period of about 30 hours. In Mar 2000 NEAR was renamed NEAR Shoemaker in honor of planetary scientist Eugene Shoemaker.

On Feb 12, NEAR landed on Eros at 35S 279W. Impact was 1.9m/s; signals were received after touchdown confirming NEAR survived the impact. NEAR was switched off on Feb 28.

Astra 1K

 2002-053A


SES satellite ordered 1998 from Aerospatiale. It is the first Spacebus 4000.  The Spacebus 4000 is also called Spacebus 3000B3S; but is different from the Spacebus 3000B3, e.g. Eurasiasat 1. 1K has the Spacebus 3000 avionics, unlike later SB4000 model. Astra 1K is to replace Astra 1B, and provide extra capacity for eastern Europe. It will also carry Ka-band capacity to back up Astra 1H. The Ku-band 10.7-11.7 GHz payload provides pan-European coverage. Beams cover UK/Ireland, continental Europe, and European CIS. Mass will be 5250 kg.

SCS (Societe Commune des Satellites) formed 1998 to merge Alcatel and Aerospatiale/Cannes built the satellite.

Launch mass 4650 kg.

MES-2 terminated after 1s with excessive fuel flow to DM engine followed by SC sep. DM vented fuel shortly after and reentered empty on Nov 28. Astra 1K was deorbited on command.

Reentry time based on TLEs was around 0120 UTC, not 0200 UTC as reported by SES.

The spacecraft was not registered by Luxembourg; an Alcatel fact sheet described Alcatel's role as a ground delivery of the satellite combined with provision of on-orbit testing (as opposed to on-orbit delivery). This implies that the owner of the satellite during the launch was SES and not Alcatel even if the former delegated operational control to the latter, and thus that Luxembourg was a launching state together with Russia.
