Update 1:06 a.m. EST: Liftoff of SpaceX’s Falcon 9 rocket confirmed. The booster, B1058, landed on the droneship several minutes after launch.
SpaceX sent off a Falcon 9 first-stage booster for a record-breaking 19th launch just after midnight as it continues the expansion of its Starlink satellite constellation. Liftoff from pad 40 at Cape Canaveral occurred at 12:33 a.m. EST (0533 UTC).
First-stage B1058 was already the fleet leader with 18 prior missions and cemented that position with the Starlink 6-32 mission, which will deliver 23 satellites to orbit. The booster first flew in May 2020 carrying astronauts for the first time on the Demo-2 Crew Dragon mission. It still features a faded NASA ‘worm’ logo from that mission.
The liftoff time slipped just over an hour from the opening of the window at 11 p.m. EST (0400 UTC) as the rocket wasn’t hoisted upright at the launch pad until around 7:35 p.m. EST (0035 UTC). SpaceX had backup launch opportunities available until 3 a.m. EST (0800 UTC) Saturday morning.
The 45th Weather Squadron at Cape Canaveral Space Force Station, said Thursday there was 60-70 percent chance of acceptable weather for launch with better conditions at the opening of the window. The primary concerns were violations of the thick cloud layer and cumulus cloud rules.
The Falcon 9 first stage landed on the drone ship ‘Just Read the Instructions’ about eight and half minutes into the flight. Two burns of the rocket’s second stage will put the 23 second-generation Starlink satellites into orbit, with deployment occurring about one hour, five minutes after launch.
SpaceX revealed this week it’s Starlink internet service now has 2.3 million users in 70 countries. Since 2019 it has launched 5,604 satellites according to statistics compiled by Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, who maintains a space flight database. As of Dec. 20, 5,226 satellites remain in orbit and 5,191 appear to be working normally.
