UPDATE: The SpaceX Falcon 9 liftoff from the Cape Canaveral Space Force Station in Florida at 11:38 pm EDT Tuesday with 22 Starlink satellites, followed by a drone ship booster landing minutes later.
Welcome to Florida Today’s Space Team live coverage of SpaceX’s Falcon 9 Starlink 6-17 mission from the Cape Canaveral Space Force Station.
If the tables hold, this year will be Space Coast’s 50th edition. For latest schedule updates, visit floridatoday.com/launchschedule.
SpaceX’s mission, which is slated to send 22 more Starlink satellites into low-Earth orbit, was originally targeted for liftoff at 10:47 pm EDT. However, the crew is now looking at a backup launch opportunity at 11:38 p.m
11:47 pm EDT: The Falcon 9 first stage landed on SpaceX’s drone ship A Shortfall of Gravitas in the Atlantic Ocean, completing its landmark 17th mission.
11:38 pm EDT: SpaceX launched a Falcon 9 with 22 Starlink satellites from Launch Complex 40 at the Cape Canaveral Space Force Station. The first stage booster’s drone ship landing will arrive in about 8½ minutes.
11:23 pm EDT: Fifteen minutes before SpaceX’s scheduled 11:38 pm EDT Falcon 9 launch, the countdown appears to be proceeding as planned and refueling at Launch Complex 40 is well underway.
11:06 pm EDT: “All systems are good for tonight’s launch of 22 Starlink satellites from Florida,” SpaceX said.
Weather is 90% favorable for climbing.
10:20 p.m. EDT: SpaceX said crews are targeting an 11:38 pm EDT liftoff time.
If necessary, three backup release opportunities will be available between 12:28 am and 1:46 am EDT Wednesday.
What’s more, there are five additional backup opportunities between 10:22 p.m. Wednesday and 1:21 a.m. Thursday EDT.
10:00 PM EDT: Here’s a rundown of tonight’s SpaceX countdown timeline. T-minus:
- 38 minutes: SpaceX’s launch controller checks the launch of the propellant load.
- 35 minutes: Rocket-grade kerosene loading and first stage liquid oxygen loading will begin.
- 16 minutes: Secondary liquid oxygen loading begins.
- 7 minutes: Falcon 9 starts engine cooling before launch.
- 1 minute: Command flight computer begins final prelaunch tests; The propellant tank starts to pressurize to flight pressure.
- 45 seconds: The SpaceX launch director checks the “go” for the launch.
- 3 seconds: The engine controller commands the engine to start the ignition sequence.
- 00:00:00: Falcon 9 liftoff.
9:36 PM EDT: Tonight’s launch by SpaceX will mark the 17th flight of the first stage booster — the first flight to reach that plateau.
After phase separation, the booster will land on the drone ship A Shortfall of Gravitas 8½ minutes after takeoff in the Atlantic Ocean.
The Space Force’s 45th Weather Squadron puts the odds of “Go” conditions for a possible launch at 60%.
“The most likely weather disturbance during the primary launch opportunity will be cumulus clouds associated with onshore moving rain,” the brigade’s forecast said.
