National Radio Astronomy Observatory to Outfit the VLBA with New Ultra Wideband Receivers

The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) has begun a major upgrade to the NSF Very Long Baseline Array (NSF VLBA) with the development and installation of state-of-the-art ultra wideband receivers capable of operating across the frequency range of 8 to 40 gigahertz (GHz). This new technology, first prototyped by NRAO in collaboration with NASA’s Jet Propulsion Laboratory (JPL), and tested on the NSF VLBA’s Owens Valley station, promises to significantly expand the scientific capabilities of the NSF VLBA.

NRAO and SpaceX Coordinate to Protect Radio Astronomy 

NRAO and SpaceX have engaged in coordinated experiments involving NRAO telescopes and the Starlink satellite constellation for over two years. Early experiments began in late 2021 with the deployment of working Starlink user terminals near the Jansky Very Large Array (VLA) in New Mexico and have continued to the present day. These experiments highlight the ways in which satellite constellations and radio telescopes might be able to coexist, provided there is mutual awareness of what the other is doing.
