Update: Falcon 9 lifts off at 8:20 a.m. EST with 22 Generation 22 Starlink V2 Mini internet satellite from Cape Canaveral Space Force Station in Florida! After the flight to the southeast, the first stage of the rocket also landed on an unmanned ship in the Atlantic Ocean.
Watch the live updates below as SpaceX targets a 8:20 a.m. ET Sunday, June 4, the launch of its Falcon 9 rocket and other Starlink satellite clusters from Cape Canaveral Space Force Station in Florida.
Delta 45 Space Launch meteorologists predict a 90% chance of “off” weather conditions for the launches of the first two Falcon 9 missions scheduled by SpaceX today, marking Space Coast’s 27th and 28th launches this year.
SpaceX dual head launch:Two Falcon 9 rockets are scheduled to launch from Florida on Sunday
The 230-foot rocket will fly from Launch Complex 40 along a southeastern trajectory with 22 second-generation V2 Mini Starlink internet satellites. Shortly after liftoff, the first stage of the Falcon 9 booster will target an unmanned landing craft in the Atlantic Ocean.
SpaceX is slated to launch another Falcon 9 rocket later today, but not from Pad 39A Kennedy Space Center. A Dragon capsule containing thousands of pounds of cargo, supplies and science experiments for the International Space Station crew will fly atop the 230-foot rocket.
SpaceX’s CRS-28 mission for NASA will lift off at 12:12 p.m. EDT. Find live launch coverage of FLORIDA TODAY starting 90 minutes before takeoff at

Updates from Sunday’s events below:
The first stage of the Falcon 9 booster has successfully landed on the “Read the Instructions” drone ship stationed in the Atlantic Ocean.
08:20 ET: Falcon 9 takes off! The missile will now fly along the eastern path and land on the “just read the instructions” drone about eight minutes later. Here’s the post-launch timeline:

08:10 ET: Ten minutes remain until SpaceX attempts to launch a Falcon 9 rocket from the Cape Canaveral Space Force Station with 22 second-generation Starlink V2 Mini satellites. This is what’s left of the countdown:
T-minus:
00:07:00 min: Falcon 9 begins engine cool down before launch 00:01:00 min: flight computer begins final pre-launch check 00:01:00 min: fuel tank pressure begins to rise to flight pressure 00:00:45 min : SpaceX launch director checking start 00:00:03 minutes: Engine control orders engine ignition sequence for start 00:00:00 Falcon 9 liftoff
07:50 ET: SpaceX has started loading kerosene and liquid oxygen into the first stage of its Falcon 9 rocket at Launch Complex 40. The countdown is still on until 8:20 a.m. EST.
07:20 ET: SpaceX continues the countdown to launch of mission Starlink 6-4 at 8:20 a.m. EDT. SpaceX reports that the weather has increased to a 90% chance of “go-go” conditions, but upper level winds are a concern. If the new time holds and the weather looks better, refueling should begin around 7:42 a.m. EST. Stay tuned.
04:45 ET: SpaceX is now in the process of lifting off at 8:20 this morning on the Starlink mission from Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This is the newest launch opportunity available for this mission today. According to SpaceX launch weather conditions, only 15% of those who “went” to takeoff on time. Stay tuned as we get closer to refueling.
04:30 ET: Good morning. As far as we know, the SpaceX team at Launch Complex 40 is counting down the launch of the Falcon 9 at 5:56 a.m. ET. But SpaceX may have to target a launch time this morning because the Falcon 9 rocket has been vertical to the launch pad for more than an hour. Additional opportunities available at 6:46 AM and 7:36 AM EST. Stay tuned as we get closer to refueling.
Here’s the pre-launch mission schedule:
T-minus:
- 00:38:00 min: SpaceX launch director inspects transition to fuel payload
- 00:35:00 min: RP-1 (rocket grade kerosene) begins loading
- 00:35:00 min: The first stage of LOX (liquid oxygen) loading begins
- 00:16:00 min: Second stage of LOX loading begins
- 00:07:00 min: Falcon 9 begins engine cooldown before launch
- 00:01:00 min: Instructs the flight computer to perform final checks before launch
- 00:01:00 min: fuel tank pressure starts flying pressure
- 00:00:45 min: SpaceX launch manager checks startup
- 00:00:03 min: Engine control commands the engine ignition sequence to start
- 00:00:00 Falcon 9 takes off
