Night owls along Florida's Space Coast could get a bright wake-up call tonight, as SpaceX targets a late-night Falcon 9 liftoff from Cape Canaveral to send SiriusXM's SXM-11 satellite toward geosynchronous transfer orbit. The four-hour launch window opens at 10:25 p.m. ET, with liftoff planned from Space Launch Complex 40 at Cape Canaveral Space Force Station. After stage separation, the Falcon 9's flight-proven first stage is expected to head for an offshore recovery, and the mission will add to SiriusXM's fleet of geostationary satellites.
Launch window and mission plan
According to Spaceflight Now, the four-hour window opens at 10:25 p.m. EDT, with the rocket set to depart from SLC-40 at Cape Canaveral Space Force Station. The flight is designed to deliver the SXM-11 satellite into geosynchronous transfer orbit, where it will later maneuver into its final operational slot. Weather conditions and range availability will ultimately decide whether the countdown ends in a liftoff or a scrub.
Booster reuse and recovery
Space.com reports that SXM-11 tips the scales at roughly 15,400 pounds (about 7,000 kilograms) and is expected to separate from the upper stage about 34.5 minutes after launch. The first stage on this mission, booster B1085, is flying for the 17th time and is slated to attempt a landing on the droneship A Shortfall of Gravitas in the Atlantic Ocean. Repeated use of flight-proven boosters and offshore droneship landings remains central to SpaceX's reusability playbook.
How to watch and backups
SpaceX plans to stream the launch on its website and YouTube, and viewers can find the company’s live feed on SpaceX. Local outlet Space Coast Daily notes that a backup opportunity is available on Monday, June 29, during a four-hour window that opens at the same time. Anyone planning to watch from the shore should keep an eye on range warnings and temporary closures at popular viewing spots, since access can tighten quickly on launch nights.
What it means for the Space Coast
The SXM-11 mission slots into an already packed launch schedule as Cape Canaveral continues to see a high tempo of flights this year, a trend highlighted in coverage of the region's surging launch cadence. That steady drumbeat keeps local viewing areas busy and puts roads and emergency services on alert whenever a nighttime launch is on deck. SpaceX and its mission partners are expected to post official updates if the launch timing or window changes.
