- The HGA is useless in its current state. The low-gain antennas can send
- high-rate data, if a receiver is relatively close.

- This was the most technically-feasible way to salvage the complete mission.
- Put the relay craft in high orbit around Jupiter, and the Galileo LGAs
- can get the high data rate that far. A light relay craft could be
- launched on a more direct trajectory to reach Jupiter in time. It hasn't
- been done, basically because it required commitment to a modest but
- substantial expenditure very quickly, and NASA can't *do* that nowadays.
