French earth land resources satellite. Trench earth land resources satellite. SPOT was the French government sponsored civil Earth observation program. A single SPOT satellite provided complete coverage of the Earth every 26 days. Earth Observing satellite built by Astrium for Spot Image, France. Launched 2002. Used the SPOT Mk.3 bus.

The system provided 5 m resolution in the panchromatic band and 10 m resolution in the multispectral bands.

SPOT 5A and 5B were the next generation of this series. Additional program support came from Belgium and Sweden. Image products from SPOT were handled by a commercial entity, SPOT-Image Corp. The spacecraft was 3-axis stabilized, with a 150 Mbps downlink rate. The payload included the HRG (High Resolution Geometry) instrument for multispectral imaging of the earth's surface. Each spacecraft carried three HRGs, one looking forward, one looking down, and one looking aft.

Total SPOT budget was $ 5 billion. Original budget was $ 1150 million for 2 units; this was cut to $ 680 million for 1 unit in June 1986. Alcatel's payload contract for $ 92.6 million was signed on 2 February 1995.

SPOT 5 - . Mass: 3,000 kg (6,600 lb). Nation: France. Agency: CNES. Manufacturer: Friedrichshafen. Program: SPOT. Class: Earth. Type: Earth resources satellite. Spacecraft: SPOT-5A-5B. USAF Sat Cat: 27421 . COSPAR: 2002-021A. Apogee: 826 km (513 mi). Perigee: 825 km (512 mi). Inclination: 98.80 deg. Period: 101.40 min.
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.

16:28 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC31. LV Family: R-7. Launch Vehicle: Soyuz-2-1A.

Metop-A - . Mass: 4,093 kg (9,023 lb). Nation: Europe. Agency: RKA. Class: Earth. Type: Weather satellite. Spacecraft Bus: SPOT-5A-5B. Spacecraft: Metop. USAF Sat Cat: 29499 . COSPAR: 2006-044A. Apogee: 817 km (507 mi). Perigee: 817 km (507 mi). Inclination: 98.70 deg. Period: 101.00 min.
European polar weather satellite equipped with high-resolution visible and infrared cameras, a microwave sounder, ozone monitors, a GPS atmospheric sounding device, a wind scatterometer, and a search and rescue package. First launch of the Soyuz 2 version of the venerable Soyuz launch vehicle. The main change in this first version of the new booster was a digital control system. Problems with this system delayed the launch repeatedly.
