SpaceX have reported that on 17 December, Starlink Satellite 35956 suffered an in-space anomaly. This satellite was launched on 23 November aboard the Starlink Group 11-30 mission from SLC-4E, California. Communications were lost with the satellite followed by venting of its propulsion tank. SpaceX states that a small number of trackable objects were released and that their orbits are low enough to not pose any threat to life aboard the International Space Station. The satellite is expected to fully decay within the coming weeks. SpaceX reports that engineers are working to determine the root cause of the anomaly as soon as possible and that a software update is in the process of being deployed to all satellites increase protections against this event

On 9 December 2025, SpaceX launched the NROL-77 to orbit from SLC-40 in Florida. The booster supporting this mission, B1096, made a return to launch site landing following stage separation. This landing marked the 16th and final landing at LZ-2 since its debut on the Falcon Heavy Test Flight in February 2018. The adjacent LZ-1 was already retired earlier this year as SpaceX reach the end of their lease agreement at SLC-13 (where LZ-1 and LZ-2 are located). Starting in the new year, all Falcon boosters performing RTLS will be required to return to the same site that they launched from. In response to this, SpaceX have constructed a new landing zone at SLC-40 which is expected to debut soon. Two similar pads are also expected to be constructed soon at LC-39A

On 8 December 2025, SpaceX successfully launched the Starlink Group 6-92 mission from LC-39A in Florida. The booster supporting this mission, B1067, became the first Falcon booster to successfully launch and land for a 32nd time

Raptor 3 SN75 completed a 388 second firing on a test stand at the McGregor Test Facility in Texas. This firing tested the planned ascent burn used to put Starship V3 vehicles in orbit. A video showing the test in full was posted by SpaceX on X

On 2nd December, SpaceX launched the Starlink Group 6-95 mission aboard Falcon 9 marking their 600th mission in total. This number includes 5 flights of Falcon 1, 11 flights of Falcon Heavy, 11 Starship test flights, and 573 Falcon 9 missions however not all missions were successful
