Tucson Offices on Forbes Blvd., October 1974
Paul Rhodes and Bill Gust stand at the entrance to the new NRAO Tucson offices on Forbes Blvd. in October 1974. Prior to moving into the Forbes Interstate Industrial Park, where the interior space was specially designed for NRAO (and included NRAO's first shower room - many Tucson employees rode bicycles to work), NRAO had occupied space in the basement of Kitt Peak National Observatory's Tucson offices. Complexity of the equipment and increasing staff numbers meant the limited available KPNO space no longer met NRAO's needs, so the search for new quarters began in 1973. Nineteen NRAO employees moved into the Forbes Blvd. offices in 1974. (GB74-11954.jpg)

Open House at the 36 Foot in Tucson, 1974
NRAO has always worked to introduce radio astronomy and to educate students, teachers, and the general public about our instruments and the exciting research conducted with them. Site tours and open houses have long been a popular and successful part of this process. In this photo, a group tours the control room of the 36 foot telescope on Kitt Peak outside Tucson in approximately 1974. Operator Don Cardarella is seated at the left and Cal Sparks, with white shirt, is standing on the right. Photo taken by Mark Gordon. tour_36ft_gordonphoto.jpg

New Surface for Tucson's 36 Foot, May 1982
In May 1982, in the Green Bank Warehouse where the work was done, John Payne (left) and John Findlay contemplate engineering issues during the fabrication process for the new surface and back-up structure that would convert Tucson's 36 foot telescope into a 12 meter telescope. The 36 foot closed for resurfacing and upgrade on 15 July 1982, and first observations with the 12 meter were made on 17 January 1984. (GB-82-20137_clean_payne-findlay-12m-fab.jpg)

VLBA Dedication, 20 August 1993
The VLBA was dedicated on 20 August 1993. In this photo, U.S. Representative Joe Skeen (left), NRAO Director Paul Vanden Bout (right), and NRAO Associate Director Bob Brown (background) watch as Senator Pete Domenici scans the bar code below the word "Start" to initiate observations of W3OH. As the antennas began to point, lights on the displayed map lit up for each station, sequencing from east to west. There also was a monitor that showed RA/Dec and Az/El for each antenna, and those numbers started changing as the antennas slewed toward their target. Bob Greschke, VLBA chief operator at the time, wrote the software for the bar-code trick that triggered the map-light sequence and then put a message on his operator's screen so he could manually start the actual pointing sequence. Thanks to Dave Finley and Bob Greschke for caption information, to Peggy Perley, Jon Romney, and Craig Walker for suggestions on finding out about the observing target, and to Jim Ogle, who searched through the (still readable!) years old Exabyte backup tape to find the source observed for the occasion. vlba_dedication_bar-code-scan.jpg

12 Meter Telescope Decommissioning, 2000
