Helicopter Lifts Historic NASA Telemetry Dish for Preservation

In a remarkable display of precision and historical preservation, NASA Armstrong Flight Research Center in Edwards, California has successfully relocated a significant artifact, once instrumental in the success of various historical aircraft and space missions, using a helicopter. The artifact, a telemetry dish anchored to a rooftop pedestal at NASA’s administration Building 4800, was meticulously removed and is slated for preservation.

Built during the 1950s, the administration building’s rooftop housed the pedestal and telemetry dish, pivotal in tracking data from groundbreaking aircraft such as the X-15, X-29, and the space shuttles during their missions. This telemetry system was essential in providing real-time data crucial for both experimental and operational analysis, enhancing safety and mission success rates significantly.

Bob Guere, NASA Armstrong Range Operations Chief, emphasized the strategic advantage provided by the rooftop location of the telemetry antenna, "You were able to support ground tests and check airplanes before they taxied without having to use telemetry antennas positioned further away," he explained. Especially during the Space Shuttle era, having a closer and unobstructed line of sight as the shuttle re-entered the atmosphere was invaluable.

The demand for relocation arose during a recent roofing renovation project of Building 4800. The retired pedestal and dish, measuring 16 feet tall and weighing approximately 2,500 pounds, were deemed too costly to remove when initially decommissioned in 2015. Recent logistical viability has now permitted their safe extraction via helicopter, a process that took meticulous planning, permission from the Air Force for airspace operation, and careful execution.

On October 3rd, a helicopter arrived, and after ensuring that the structural integrity of the eight anchoring bolts was sound, attached a cable to the pedestal. In a slow ascent, it was then moved to a storage facility on the south side of the building. Following the removal, the steel platform was dismantled to make room for new roofing materials.

The future of the pedestal and dish is promising with preliminary plans hinting at their display alongside renowned retired research aircraft near the entrance of NASA Armstrong. This initiative not only honors the heritage of aerospace innovation but also educates the public on the critical role telemetry has played during several key eras in flight history.
