Seeking interviews with Phobos experts
Posted by JimO on 7/21/2008 1:59:15 PM
For a feature article in 'a major science magazine
I'd like some interviews on latest thinking on the martian moon
Phobos, apropos of the Russian probe next near to return samples to earth.

Specifically, what is it about Phobos that we now realize:

1 -- makes it an intriguing science subject, both for
itself, its relation to main belt asteroids, and possibly as
a locale for Mars-surface-origin materials

2 -- makes it a useful resource for future human missions
in the area, particulary for resources such as water, oxygen,
radiation/thermal shielding mass, etc.

For example, if the crater chains are ancient remains of
Stickney-induced deep internal boil-off of volatiles, what
is the likelihood that not all the volatiles boiled off, but
in some dikes might actually be preserved as now-refrozen
water, etc.? [what is the estimated underground temperature
of Phobos, by the way?]

Specific question regarding reaching Phobos -- it's too
simple to think of it as an 'offshore island' since it is in
its own orbital inclination over the Mars equator, at significant
inclination to the ecliptic. What plane change costs
does this induce for arriving spacecraft from Earth,
and what are proposed orbital maneuvers that
have been considered to minimize these costs?

Lastly, with these and other considerations, what
might be learned about Phobos from the Russian probe
that would contribute to planning for science missions for future
US probes, and ultimately, for human visits?

Any suggested names, phone numbers, or email address, please?
