Astra 2A
1998-050A
Astra 2A, an HS-601HP satellite, was launched by ILS Proton no 383-01 using a Blok DM3 upper stage. It was stationed at 28.2E.
One debris object was found in a 207 x 448 km orbit after the DM burns.

SMART-1
2003-043C
SMART (Small Mission for Advanced Research and Technology).
ESA satellite for power technologies. Developed by SSC/Solna. [710] and assembled by Saab Ericsson Space. Managed at ESTEC and control from ESOC/Darmstadt. Launch in 2002 to test electric propulsion system in lunar orbit; precursor to BepiColombo. The X-ray spectrometer, derived from XMM instruments, will provided astronomical obs in the cruise phase and chemical analysis at the (not yet chosen) target.
Box + 2 panels, 1.2m cube bus, 14.0 span Mass 370 kg fuelled, 255 kg dry.
In Feb 2004 the ion engine was restarted for a 1.5hr burn around each perigee.
Impact mass 285 kg inc 3 kg N2H4, 0.3kg Xe Flash expect V=16. Ejecta reaches sunlight, more visible and could reach V=6.
Payload:
- 75mN SNECMA PPS-1350 Hall effect electric propulsion system (Stationary plasma thruster, Xe)
- 70 kg Xe propellant
- Hydrazine AOCS (45 kg prop?)
- OBAN Spacecraft nav experiment
- Laser comm link
- AMIE Micro-imager, ESA: Asteroid/Moon micro-Imager Experiment
- SPEDE Plasma and dust environment, Finland; 2 Langmuir probes
- EPDP Electric Propulsion plasma diagnostic package, Italy
- KATE Ka/X band deep space communications experiment
- RSIS Radio science investigations, Roma (Uses KATE transponder)
- D-CIXS Compact x-ray spectrometer, RAL lunar geochemistry mapping, Earth glow, comet emission
