SpaceX is targeting Tuesday, September 17 at 6:50 p.m. EDT, 2250 UTC (September 18 00:50 CEST) for a Falcon 9 launch of the European Commission’s Galileo L13 mission to medium Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. If needed, there is a backup opportunity on Wednesday, September 18 at 6:46 p.m. EDT.

This will be the 22nd launch for this Falcon 9 first stage booster, which previously launched CRS-22, Crew-3, Turksat 5B, Crew-4, CRS-25, Eutelsat HOTBIRD 13G, O3B mPOWER, PSN SATRIA, Telkomsat Marah Putih 2, and 12 Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

Rapid and reliable reusability is key to making life multiplanetary – every mission is an opportunity to learn and inform future missions. During the Galileo L12 mission earlier this year, the Falcon 9 booster was expended to provide the additional performance needed to deliver the payload to its orbit. Data from that mission informed subtle design and operational changes, including mass reductions and trajectory adjustments, that will allow us to safely recover and reuse this booster. Falcon 9 is ready to safely deliver Galileo L13 to orbit and return to the droneship in the Atlantic Ocean.

The booster reentry trajectory will result in higher heating and dynamic pressure on the booster than many of our historical landings. Although the reentry conditions are on the higher end of past missions, they are still acceptable. This landing attempt will test the bounds of recovery, giving us valuable data on the design of the vehicle in these elevated entry conditions. This in turn will help us innovate on future vehicle designs to make our vehicles more robust and rapidly reusable while expanding into more challenging reentry conditions.

Due to the pair of satellites' higher target altitude and higher inclination of the targeted orbit, the Falcon 9 Booster stage needs all the fuel during the launch. The booster must have mostly 9% of the propellant of the first stage for the landing process on an autonomous drone ship or at a landing zone near the launchpads (Cape Canaveral Space Force Station or Vandenberg Space Force Base). If the mass and inclination are the same as the first pair of satellites of the constellation, which were launched in April 2024 by SpaceX with a Falcon 9, the booster will be discarded. If not, it will land on an autonomous droneship (TBD) stationed in the Atlantic Ocean.

The satellites of the Galileo-Constellation were mainly launched by Arianespace with a Soyuz ST rocket with a Fregat upper stage from the Guiana Space Center in French Guiana. However, because of the political situation, the launch of a Soyuz rocket from French Guiana was stopped in 2022. Initially, the satellites should have been launched with the new ESA rocket Ariane-6, but because of the long delays of the successor to the Ariane-5 rocket, it was scrapped.

Europe contracted SpaceX to launch the two pairs of Galileo satellites with a Falcon 9 rocket for approximately €180 million. The first pair was launched in April 2024.

For this launch, the booster will be discarded.

She reads the same script for every launch.
