Hello friends
at first, I should say so your tragedy with Columbia are our tragedy
too.
............................................................................................
There are well known idea about Bracewell probe or more
exact we should say idea of Tipler probes so if there are ETI
hence there must be _some_ numbers of ETI'es probes near Earth.
After first and naked view we say there are no nothing like same probes
near Earth.
But question, what position is optimal for probe? Of course our first
answer
it must be positions on the lagrangian points of Earth - Moon system.
But really it's so optimal?
Last years gave to us some examples of asteroids with more best
locations -
2000 SG344

Of course it maybe is only Apollo fragment (
http://www.iau.org/IAU/FAQ/sg344.html )
but there are some other asteroids with similar orbits
examples:
2000 LG6
http://neo.jpl.nasa.gov/cgi-bin/db_shm?sstr=2000+LG6&search=Search
and
2001 GP2
http://neo.jpl.nasa.gov/cgi-bin/db_shm?sstr=2001+GP2
Note, there must be only one correction on some hundred years against
one correction for some month on lagrangian points for stabilization of
near Earth orbit. And near Earth velocities are at order of ~ 1 km/s.
Also, we have Moon and Earth-Moon system but for more current
cases (without Moon) there must be more current strategy for long
orbital
probe.
