Hyperion exceeded our expectations in its ability to track a sun-synchronous
route, traveling over 90% of its 6.1km circuit autonomously and
about 10% with remote supervision, to arrive at the final goal with batteries
charged (July 18-19). In the second experiment (July 21-22), in which we increased the distance
and difficulty of the terrain, Hyperion also performed admirably
despite some difficulties, and again
reached the final goal on schedule with charged batteries.
