\n\t\t\t\t\t\tNASA’s Commercial Satellite Data Acquisition (CSDA) program has acquired commercial datasets from Orbital Sidekick.\t\t\t\t\t<\/p>\n<\/p><\/div><\/div><\/div>\n Orbital Sidekick, Inc. operates a three-satellite constellation carrying identical hyperspectral instruments that deliver high-resolution (8-meter) hyperspectral imagery across 472 spectral bands to support a range of Earth science applications, including the detailed analysis of biodiversity, ecosystem health, and surface geology; greenhouse gas detection; and detecting solid chemicals related to pollutants. Each satellite is designed with a maximum off-nadir pointing angle of 25 degrees, which expands the accessible ground swath and enables flexible tasking. When operating individually, each satellite provides regular revisit opportunities across mid- and low-latitude regions. When operated as a three-satellite constellation, the revisit rates increase, particularly at higher latitudes, where overlapping orbital tracks provide enhanced temporal coverage. This capability allows users to receive frequent, daylight-consistent revisits around the globe to support the monitoring of both broad-areas and specific areas of interest.<\/p>\n All newly awarded commercial data provider products are currently undergoing CSDA evaluation.
