1.  Name one independent scientist not employed by or under contract by NASA
who has been invited by NASA to scientifically peer review Malins' raw Mars
photographic data.

Ask the Planetary Data System node responsible for archiving the Mars
imaging data (CCD images aren't what I would call "photographs").  I
know that the Small Bodies Node can name the peer reviewers for the
data sets they handle (like NEAR's).  Mars belongs to another node,
maybe the Imaging Node.
