"Joe has played an extremely important role for both our
office and the agency as a whole throughout his many years with
NASA... Not only has he performed critical roles in each of
his four shuttle missions, from servicing the Hubble Telescope to
assembly work on the International Space Station, but his
leadership and expertise have been invaluable resources to us on
the ground as well. He will be missed."
