In general, all technology development work for M&MV will take advantage of past and
relevant technology developed for other Projects. In particular, we will review model validation
work performed under the SIM and JWST projects, and fold into our activity where appropriate.
We will also survey industry and academia for availability of test facilities and information
consistent with the M&MV technology goals.
