GPS Upgrades Stall as Vulcan Glitches Drive Space Force Toward SpaceX

The Space Force has paused further launches on ULA’s Vulcan rocket while investigators probe a February 2026 booster anomaly—the second such issue after a 2024 carbon‑composite insulator defect—pushing GPS satellite launches toward SpaceX’s Falcon 9. The investigation is expected to last months as officials seek root cause and corrective actions. Meanwhile, GPS modernization continues: 26 of 31 satellites carry the M-code signal and 19 broadcast the higher‑power L5 civil signal, underscoring the value of having multiple launch providers to maintain global coverage amid rising interference and jamming threats.

Space Force pauses Vulcan launches after booster anomaly

Space Force has halted Vulcan rocket launches after an anomaly with a solid-rocket booster was observed on the USSF-87 mission. Investigators will work with ULA and Northrop Grumman to determine corrective actions before resuming Vulcan flights, with no set resumption date and potential fallback options such as SpaceX if Vulcan remains grounded. GPS III SV-10 remains on the national security launch manifest for no later than next month as ULA addresses the booster issue while pursuing its cadence goals.

SpaceX to Launch GPS-3 Satellite on Falcon 9 After Vulcan Swap

The U.S. Space Force will launch the GPS 3-9 satellite into medium Earth orbit on SpaceX's Falcon 9 after moving the satellite from ULA's Vulcan rocket; the mission uses M-Code for jam-resistant PNT, is managed by SSC and CFC under the National Security Space Launch program, and underscores the Air Force's flexibility in juggling launch manifests to deliver critical GPS capabilities.

Ariane 6 Achieves Third Launch as Europe Leads in Earth Observation

Ariane 6 successfully launched its third mission, beating Vulcan to this milestone, while China deployed its sixth batch of Guowang satellites using the Long March 5B. SpaceX launched its 100th mission of the year, including satellites for Amazon's Project Kuiper, highlighting its dominant role in commercial space launches. The Portuguese government approved a spaceport in the Azores, and China revealed its first marine rocket recovery ship. ULA's Vulcan rocket achieved its first national security launch, marking a key operational milestone. Additionally, NASA's Artemis II astronauts trained for nighttime launch procedures, and China continues expanding its satellite internet constellation.

"End of an Era: Delta IV Heavy's Final Launch Marks the Close of 60 Years of Delta Rockets"

The Delta IV Heavy rocket, known for deploying national security satellites and critical NASA missions, is set to take its final flight from the Cape Canaveral Space Force Station. United Launch Alliance's next-generation rocket, the Vulcan, will seamlessly replace the Delta IV Heavy, offering increased capabilities and reusability. The last launch of the Delta IV Heavy is scheduled for Thursday, marking the end of an era and the beginning of a new chapter in space exploration.

ULA's Vulcan Rocket Set for Debut Launch and Packed Schedule

United Launch Alliance (ULA) is preparing for the first launch of its Vulcan Centaur rocket, with all major components now at the Cape Canaveral launch site. The Centaur upper stage, called Cert-1, arrived on November 13 and will be integrated with the Vulcan booster. The primary payload for the launch is Astrobotic's Peregrine lunar lander, which will carry payloads for NASA's Commercial Lunar Payload Services program. The launch is scheduled for December 24, with two backup windows on December 25 and 26. ULA plans to increase the Vulcan launch rate to twice a month by the end of 2025.

Boeing's Starliner and Dream Chaser space plane launch dates delayed.

Sierra Space's Dream Chaser, one of NASA's commercial cargo spacecraft, will delay its first launch to the International Space Station until December, a five-month delay from August, due to unknown reasons. The spacecraft will be launched using a new booster from United Launch Alliance called Vulcan. Vulcan is also facing development issues of its own ahead of flying the two certification missions. This will leave NASA with a single operational rocket type that supplies cargo vehicles: The SpaceX Falcon 9.

The Myth of Planet Vulcan: Debunked.

The Myth of Planet Vulcan: Debunked.

The exoplanet 40 Eri b, previously thought to be the real-life version of the fictional planet Vulcan from Star Trek, has been disproved by a new study. The gravitational pull thought to be caused by the planet was actually caused by the star's surface activity. The radial velocity method used to detect exoplanets has limitations in detecting smaller exoplanets and those orbiting further away. While there may be other planets orbiting 40 Eridani A, none are currently suspected.
