STG representatives felt that the most useful feature of the Prospector program lay in its planned ability to soft-land cargo in close proximity to a desired site. Many applications could be foreseen, such as the deposit of landing aids and essential material in support of a manned lunar landing or in continuing support for a manned lunar expedition. However, the Prospector roving vehicle seemed to be a much more complicated and heavier piece of hardware than a manned lunar transport and, for that reason, STG did not support its development. The planning for Prospector involved JPL in-house studies concerning closer integration with manned space flight requirements, definitive decisions on the program within several months, a contractor's study in Fiscal Year 1962, engineering design in Fiscal Year 1963, and a hardware contract at a future date. Future Prospector planning would emphasize its cargo-carrying ability as a prime requirement, JPL representatives stated.
