NASA's Spectre Instrument to Enhance Near-Earth Object Detection at Mauna Kea
NASA is developing the Spectre instrument for the Infrared Telescope Facility at Mauna Kea, aimed at enhancing the detection and characterization of near-Earth asteroids. This advanced spectrograph will enable rapid assessments of asteroid composition, size, and mass, playing a crucial role in planetary defense. With major components already in Hilo, integration and testing are scheduled before its expected installation in 2028.

NASA is developing a new instrument named Spectre for the Infrared Telescope Facility on Mauna Kea, Hawaii, to rapidly characterize near-Earth asteroids. As astronomical survey facilities advance, the discovery of potentially hazardous asteroids is expected to rise.
Spectre will provide swift spectroscopic observations to assess the composition, size, and mass of these objects. Designed as an integral field spectrograph, Spectre can capture a wide range of wavelengths simultaneously, essential for identifying faint and fast-moving asteroids.
Its construction includes a vacuum-sealed structure housing three spectrographs, operating at extremely low temperatures to minimize infrared interference. Major components have arrived in Hilo, with integration and testing set before its installation in 2028. Once operational, Spectre will contribute significantly to planetary defense and enhance the understanding of both near-Earth objects and other astronomical phenomena.
