A spy satellite for the U.S. National Reconnaissance Office was launched from Vandenberg Air Force Base on Saturday night, putting some nervous Californians on edge.
A United Launch Alliance Atlas 5 rocket carrying the classified NROL-42 satellite lifted off at 10:49 p.m. PDT Saturday. All systems were going well when the launch webcast concluded about three minutes into the flight.
The launch was expected to be visible across a wide area of California, weather permitting, and it prompted several anxious tweets.
Anyone else in LA see the comet/rocket looking projection in the night sky? Are we testing missiles or is there a very orange shooting star?— Jono Zalay (@JonoZalay) September 24, 2017
National Reconnaissance Office satellites gather intelligence information for U.S. national security and an array of other purposes including assessing impacts of natural disasters.
U.S. officials have not revealed what the spacecraft will be doing or what its orbit will be.
United Launch Alliance is a joint venture of Lockheed Martin and Boeing.
