1988-026A
The long delayed NASA/CRA San Marco D/L satellite finally left the pad in Mar 1988, becoming San Marco 5. The satellite, with a mass of 237 kg, carried more sophisticated instruments than its predecessors. A companion spacecraft, San Marco D/M, was never launched. L stood for 'low orbit' and M for 'medium orbit'.
