The extragalactic radio astronomy program at Massachusetts                      Institute of Technology (MIT) will emphasize the study of                       gravitational lenses, the development of Very-Long-Baseline                     Interferometry (VLBI) and the study of the structure of                         extragalactic radio sources.  The principal observational task is               to complete the MIT survey, including the production of the 4000                self-calibrated radio maps that constitute the core of the work.                That material forms the basis of gravitational lens search,                     carried out jointly with colleagues at Princeton and California                 Institute of Technology.  The VLA snapshots are examined and                    classified, and the most likely gravitational lensing.  The                     resulting examples will then be used to study the distribution of               matter in galaxies and in the universe as a whole.                                                                                                              The temporal variations of lensed complexes will be followed, and               as in the first successfully monitored example, there will be a                 concerted effort to determine the value of the Hubble constant,                 and if the value is discordant, to understand the cosmological                  implications of such variations.                                                                                                                                The survey will also provide raw material to allow the search for               radio galaxies and quasars of very high redshift.
