Certainly, that would be a better solution, but that's a seperate pile
of money generally. While a new beacon could just be an add-on to an
existing orbiter or other mars bound vehicle.

Now I agree that DSN should be upgraded, but how? Are lasers
effective over interplanetary distances yet? Or something in the IR
range would be better? I dunno...


I think we just need MORE of the current RF technology DSN. Accurate range
and range rate info I think is good enough for navigation. Data flow is
also needed. I think all we need is to put up some more DSN antenaes.
