Program: SPOT. Objective: Earth. Type: Landsat. Overview: Remote sensing satellite network.
Major Events:
- 1993 September 26 - SPOT 3. Spacecraft: SPOT-1-2-3. Mass: 1,907 kg (4,204 lb). Launch Site: Kourou. Launch Vehicle: Ariane.
Remote sensing.
- 1998 March 24 - SPOT 4. Spacecraft: SPOT-4. Mass: 2,755 kg (6,073 lb). Launch Site: Kourou. Launch Vehicle: Ariane.
Developed by Matra Marconi Space/Toulouse for CNES, the satellite provided 10-m resolution images with a wide field of view. SPOT 4 also carried a wide field 'vegetation' imager and a laser communications experiment. Launch was by an Arianespace Ariane 40 rocket, the base Ariane 4 model with no strap-on boosters. The liquid hydrogen fuelled third stage of the Ariane 40 entered an 800 km sun-synchronous orbit together with SPOT 4.
- 2002 May 4 - SPOT 5. Spacecraft: SPOT-5A-5B. Mass: 3,000 kg (6,600 lb). Launch Site: Kourou. Launch Vehicle: Ariane.
Remote Sensing satellite. Last launch of Ariane 42P version. Launch delayed from April 10. The Ariane 42P, with two PAP solid boosters, flew north from Kourou. The third stage burn occurred off the east coast of North America, with engine cutoff at 0150 UTC and stage separation at 0151 UTC. Venting of the remaining third stage propellant was seen by observers in the US. SPOT Image's SPOT 5 was built by Astrium/Toulouse. The main instrument was the HRVIR imaging camera payload including a 2.5-meter resolution imager. A secondary experiment was the 5-band VEGETATION-2 instrument with 1-km resolution.
