The pedestal, which was prepared for a helicopter lift to remove it from the roof, was used since the 1950s until 2015 to enable different telemetry dishes to collect data from research aircraft.<\/div>\nNASA\/Carla Thomas<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\nThe rooftop pedestal was key in the early days of the center and its refurbishment in 2003 restored its value. The transformation also included certification to meet Space Shuttle Program landing requirements.<\/p>\n
\u201cWhen a space shuttle deorbited from space it was coming over the top of Edwards,\u201d Guere said. \u201cTelemetry antennas on the hill near NASA Armstrong looked down and with dirt and concrete in the background there were reflections. The rooftop antenna was closer to ground level and looked up as the orbiter was coming in for a landing. It provided an excellent link for shuttle landings.\u201d<\/p>\n
The pedestal and dish were not removed when it was decommissioned because of the cost. Now, it\u2019s economical to use a helicopter to remove the pedestal from the roof compared to other options as part of a major project focusing primarily on re-roofing Building 4800. The helicopter lift of the pedestal took a month to plan, plus time to obtain airspace operation and landing permits from the Air Force for the removal project, said Bryan Watters, NASA Armstrong roof project manager.<\/p>\n

The pedestal was used since the 1950s to 2015 to house different telemetry dishes to collect data from research aircraft.<\/div>\nNASA\/Carla Thomas<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\nThe pedestal and riser measured 16 feet tall above the rooftop and housed an assembly for the 12-foot dish to rotate. The pedestal and dish together weight about 2,500 pounds and were removed separately. Crews checked the eight bolts anchoring the pedestal and dish to infrastructure on the roof prior to the arrival of a helicopter Oct. 3 before the helicopter arrived.<\/p>\n
The following day, after additional briefings, the helicopter was positioned over Building 4800 and a cable was lowered and attached to the pedestal. Once secured, the helicopter slowly gained altitude and took its passenger to the south side of the building. There it was released from the cable and taken to a nearby warehouse for storage. Roofers demolished the steel platform on which the pedestal was located to prepare the area for new roofing materials.<\/p>\n
Officials have not determined where the pedestal will be displayed. There are several options to place the pedestal and dish by the famous retired research aircraft on display near the entrance of NASA Armstrong.<\/p>\n
