Other Designations: Satelite de Coleta de Dados. Class: Technology. Type: Communications. Destination: Medium Earth Orbit. Nation: Brazil. Agency: Instituto Nacional de Pesquisas Espacias, Sao Jose. Manufacturer: INPE. Environmental data relay. The SCD (Satelite de Coleta de Dados - Data Collection Satellite) was a Brazilian satellite designed for the collection of meteorological data relayed by data collection platforms spread throughout the Brazilian territory. It was launched by Orbital Science Corporation Pegasus launch vehicles or Brazil's indigenous VLS launcher.

- 1998 October 23 - SCD-2 - Launch Site: Mayport DZ. Launch Complex: -. Launch Vehicle: Pegasus. Mass: 110 kg (240 lb). Perigee: 742 km (461 mi). Apogee: 768 km (477 mi). Inclination: 25.00 deg.
Brazil's SCD-2 satellite was aboard Orbital Science's L-1011 Stargazer aircraft when it took off from the Cape Canaveral Air Station's Skid Strip (Runway 02/20, 28.2N 80.6W) at 23:05 GMT on Oct 22 and flew to the drop zone near Cape Canaveral (in the Mayport, Florida, Warning Area) at 29.0N 78.3W. The Pegasus ignited 5 seconds after drop. The first stage carried a NASA experiment attached to its right wing, to study hypersonic boundary layer separation. The 115 kg Satelite de Coleta de Dados (Data Collection Satellite) relays data from environmental monitoring stations.
