- You *have* to put it in orbit around Jupiter. Putting a relay halfway
- between Earth and Jupiter is utterly useless; it has to be practically
- in Galileo's back pocket for it to receive high-rate transmissions from
- the low-gain antennas.

- There really is very little advantage to doing this in orbit. Lighter
- construction, yes, but much higher costs and no maintenance access.
- With the current state of space transportation, you're better off building
- it on Earth.
