LERC/SAMSO Launches
Search, filter and explore every orbital launch ever attempted — cross-linked to the satellites they deployed, the rockets that flew them and the operators behind them. Built on GCAT & Launch Library 2.
Orbital Radar lists 16 orbital launches by LERC/SAMSO, part of 7,332 orbital launches catalogued since 1957. Every entry links to the rocket, the operator and the satellites it deployed.
