He probably hasn't had a chance to vote on it. DC-X is a part of
the SDIO program and SDIO (Star Wars) is DOD. The Subcommittee
is specifically non-military.

If we send 2 probes to Pluto, maybe we should design them so that they
can "talk" to each other. In case one has a stuck antenna, like one
we have en route to Jupiter. Then one can relay data from the other.
Or a dead high power transmitter, or a deaf receiver, and such.
I suppose that someone has figured out what design to change, or do better,
to avoid "stuck antenna" problems?

Actually, the launches don't have to be 3.2 days apart. You can easily
adjust the arrival times enroute. Also, it is quite likely that the
arrival times would be perhaps as much as a year apart, though still
designed to image the opposite hemisphere. The reason for the delay is
to permit the data from the first encounter to be played back and
analyzed before designing the details of the second encounter. The bit
rate is quite low in the current design, so playback could take several
weeks.

Although an orbiter has been discussed, the current mission design calls
for only a flyby. To go into orbit, you need to travel more slowly,
thus flight times are longer. And you need to carry more fuel, which
impacts the size of the instrument payload. All kinds of tradeoffs.

A good book is 'Great Mambo Chicken and the Transhuman Condition' by
Ed Regis (Addison Wesley, ISBN 0-201-56751-2). This is a book about
visionary scientists and engineers. (The space people are among
the tamest of the lot. Much of the book is devoted to nanotech, cryonics,
far edge parties, etc.)
