During my tenure at the USGS, I began working with Gene Shoemaker on impact craters.
My interest has been conducting gravity surveys over large craters to determine their
structure. Over the last few years, I've worked on numerous craters in Australia, in the
Canadian arctic, and in the U. S. This research has involved some fun field trips to
The flight project work involves developing the science requirements for the overall
Mars Surveyor Program, developing science objectives for specific missions, understanding
the requirements that the science instruments impose on spacecraft and trying to maximize
the science return from a given mission within the constraints of time, money and
hardware. The planning for human missions to Mars involves understanding what we need to
know about the martian environment to safely land the crew (things like the surface
radiation environment, to the chemistry of the soil, to the number of large rocks that
could interfere with landing) and to plan for the science that the crew will do when they
are there. Hopefully humans will visit Mars in the 2015 time frame, probably too late for
me to go!
