. "3"^^ . . "Lacrosse or Onyx is a series of terrestrial radar imaging reconnaissance satellites operated by the United States National Reconnaissance Office. While not officially confirmed by the NRO or anybody in the U.S. government, for a long time, there was and is widespread evidence to confirm its existence, including one NASA website. In July 2008, the NRO itself declassified the existence of their SAR satellite constellation. According to former Director of Central Intelligence Admiral Stansfield Turner, Lacrosse had its origins in 1978 when a dispute between the Central Intelligence Agency and the U.S. Air Force as to whether a combined optical/radar reconnaissance satellite (the CIA proposal) or a radar-only one (the USAF proposal) should be developed was resolved in favor of the USAF. Lacrosse uses Synthetic Aperture Radar as its prime imaging instrument. It is able to see through cloud cover and also has some ability to penetrate soil, though there have been more powerful instruments deployed in space for this specific purpose. Early versions are believed to have used the Tracking and Data Relay Satellite System (TDRSS) to relay imagery to a ground station at White Sands, New Mexico. There are some indications that other relay satellites may now be available for use with Lacrosse. The name \"Lacrosse\" is used to refer to all variants, while \"Onyx\" is sometimes used to refer to the three newer units[citation needed]. Unit costs (including launch) in 1990 dollars are estimated to be in the range of US $0.5 to 1.0 billion (inflation adjusted US$ to billion in )."@en . "5"^^ . . . . . "Low Earth"@en .
