Description:The 500th move of a VLA antenna took place on 5 November 1984. The cartoon, drawn by Paul Harden, commemorates the milestone event and the dedication of the transporter crews. The crews braved scorching sun and blowing snow (and probably blowing sand), as well as wobbling tracks (and sometimes broken ones as the cartoon suggests) to move antennas to a new location. The transporters at that time were named Hein's Trein and CamTrak, honoring long-time NRAO staff members Hein Hvatum and Cam Wade. Photograph of original cartoon drawn by Paul Harden. [show more]

Construction |
Description:Before any VLA construction began, there was extensive soil testing at the site in the center and along all the proposed arms. Environmental engineering firms, geologists from New Mexico Tech, several local drilling companies, and local excavators were all involved in the multi-month process, and many core samples were extracted for analysis. In this 31 August 1973 photo, the rig from Albuquerque Testing is drilling a test hole on the southwest arm to extract core samples. The Lorenzo well is in the background. [show more]

Description:In June 1974, John Payne (back to camera), Mike Balister, and Ken Kellermann consider the four frequency Cassegrain receiver and feed assembly, with optics designed by Peter Napier, that was the prototype system for the VLA and was also used for the VLBA. It was a new and innovative concept, first developed by the Jet Propulsion Laboratory for use on their Deep Space Network antennas, where the four feeds were offset from the electrical axis and could be illuminated by rotating the asymmetric subreflector. Here it is being installed for testing on the 140ft antenna in Green Bank. Mike says, "Judging by the way I was clutching my head [Ken] must have been giving us a hard time." Ken says he was the project scientist "assigned to hassle the Electronics Division." He adds, "Note I was comfortably sitting down and seem to be the only one that didn’t look puzzled, as appropriate for an advisor." After installation of the Cassegrain cabin on the 140 ft telescope the system was integrated and evaluated by Chuck Brockaway and Tom Dunbrack. [show more]

Description:Grote Reber at the VLA, 23 March 1976. Antenna #1 in the background. In 1966 and 1967 Reber had written repeatedly to Everett Hurlburt, NSF Program Director for Radio Astronomy, urging him not to fund "technological dinosaurs" such as NRAO's Largest Feasible Steerable Telescope project and the VLA, saying, "Decades will pass before either could be realized." By the time he visited the VLA, Reber had changed his opinion enough to write on 4 May 1976 to Jack Lancaster, VLA Project Manager, "The day at VLA was enlightening. I know a lot of difficult ground work has gone into getting the project this far. From now on the plant will show rapid development. Someday I will come and make observations with this radio telescope to end all radio telescopes." [show more]

Description:The VLA was used with Jet Propulsion Laboratory’s Deep Space Network in Goldstone CA to track NASA’s Voyager 2 encounter with Neptune in 1989. NRAO began planning and preparations in 1982, and test phased array observing on Voyager and planets began several years before the encounter as more antennas became outfitted for X-band. NRAO devoted 340 hours of VLA observing time to system tests and reception of Voyager's telemetry, and there were 40 scheduled telemetry passes from 26 April through 28 September 1989. This November 1985 sketch by Socorro's Paul Harden shows Bill Brundage (NRAO) and Ron Logan (JPL) with the test instrument setup at the VLA. [show more]

Description:On 30 January 1974, following several years of discussion on transporter requirements and possible designs (both within NRAO and with outside firms), E-Systems Inc. was awarded the contract for design and fabrication of transporter #1 for the VLA. The transporter was crucial to making the VLA a flexible instrument that could operate in multiple configurations. An 11 February 1977 memo states, "We tend to underestimate the complexity of the design and construction of the vehicle, which picks up 220-ton antennas and transports them through 90[deg] intersections. That it works as well as it does is an engineering achievement of the first order...." Transporter #1 was named Hein's Trein, honoring long-time NRAO Associate Director Hein Hvatum. [show more]

Description:VLA antenna 19 crossing Rt. 60. On 18 January 1980, VLA crews moved antenna 5.2 km out the North Arm, thus necessitating the first antenna crossing of Rt. 60. Many turned out to witness the event, including NRAO personnel, news media, and the State Highway Dept., who came to measure traffic disruption and check safety procedures. All went smoothly.
