Abstract:

Primary goal of this contract was to make flight use of two balloon- borne telescope systems that had been built under previous contracts, a 24-inch system and a 50-inch system. A number of significant improvements were incorporated into the 50-inch system that enhanced its capability, and several proposals for other major changes were studied but were not implemented. The 50-inch system was used in all flights because its capability was better suited to the experiment objectives. Extensive work was done on the 24-inch system in the hope that it could be used in daytime experiments, but the target objective of tracking Mercury when it is high in the sky and close to the sun could not be achieved.
