Description:In May 1982 NRAO submitted to NSF the proposal to build and operate what became the Very Long Baseline Array. Construction began in Pie Town NM in February 1986 on the first VLBA antenna; construction on the tenth and final antenna on Mauna Kea HI was completed in April 1993, and on 29 May 1993 the first observations were made using all ten VLBA stations. In this photo, taken by Peter Napier on 27 January 1992, the Mauna Kea antenna is in the initial stages of construction. [show more]

Description:This photo from early 1992, was taken at the proposed center of the MMA site in the Magdalena Mountains, now the site of the Magdalena Ridge Observatory Interferometer, looking north toward the South Baldy summit. Visiting observer Don Backer with NRAO staff members Joan Wrobel, Dave Wunker, and Phil Dooley, make one of the frequent visits to that site to check snow levels and tipper data. Craig Walker says Backer's skis and poles were borrowed: "Don's participation in one of our South Baldy trips is something we remember well. He was here on other business and had to borrow gear. Hence the blue jeans (rather inappropriate for a ski trip) and the satchel rather than a pack." Perhaps his upside pole is informally measuring snow depth? A crane at one of the NMIMT research sites is just visible over the crest. [show more]
