SPACEX on Wednesday launched a US government spy satellite into orbit on a highly classified mission.
The National Reconnaissance Office probe lifted off at 12:27 下午. local time from Vandenberg Space Force Base in California aboard a Falcon 9 火箭.
The launch was webcast until the spacecraft’s first stage completed its burn and separated from the second stage.
Under NRO rules, coverage of the continuation of the flight – which was carrying the satellite NROL-87 – to orbit ended at that point.
The Falcon’s first stage flew back to the seaside base northwest of Los Angeles and landed so that it can be reused in a future NRO mission.
Central Coast residents were advised by SpaceX – billionaire Elon Musk’s private rocket firm – to expect sonic booms as the booster returned.
The NRO only described the NROL-87 satellite as a national security payload.
Its launch was one of three awarded by the Air Force to SpaceX in 2019 for a combined fixed price of $297million.
The NRO is the government agency in charge of developing, 建造, launching and maintaining U.S. surveillance satellites.
Those probes provide intelligence data to senior policymakers, the intelligence community and the Defense Department.
The office plans more than a half-dozen launches this year to place nearly a dozen payloads into orbit.
There were two NRO launches last year, NROL-82 from Vandenberg and NROL-111 from NASA’s Wallops Flight Facility in Virginia.
The NRO has launched 16 other satellites over the past two years.
It comes just days after online space junk trackers warned that a SpaceX booster is on a collision course with the Moon.
