Spacecraft payload optimization
Eos, Transactions American Geophysical Union, 1976 Many factors are considered in the selection and integration of scientific experiments for spacecraft payloads. Ideally, the payload should provide maximum scientific value subject to the finite limitations of cost, telemetry, power, weight, and volume imposed by the scope of the mission.
