Today's Space Brief covers the inaugural national security mission of ULA's Vulcan Centaur, the Space Force's 2026 budget insights, and shifts in military drone technology.
Today's brief covers SpaceX's latest Starlink launch, fascinating exoplanet discoveries, and strategic lunar developments by China and South Korea.
On April 17, 2026, the U.S. Space Force officially cancelled the Next Generation Operational Control System after sixteen years of development, cost overruns, and testing failures. The $8 billion program was supposed to unlock the military's encrypted GPS signal. Instead, the satellites are flying with capabilities the ground can't command.
Northrop Grumman's GEM 63XL solid rocket booster passed static fire testing, but ULA's investigation into a February 2026 Vulcan in-flight anomaly remains open. No RTF date set.
SpaceX continues to make strides in both its Starship program and Starlink satellite deployments, with a successful launch of 24 Starlink satellites and preparations for upcoming missions.
SpaceX successfully launched 29 Starlink satellites on November 14, marking the first of two rapid-fire Falcon 9 missions from Florida's Space Coast in under four hours.
Seven years ago, SpaceX revolutionized spaceflight by launching the most powerful operational rocket in the world, carrying with it a cherry-red Tesla Roadster that captured global imagination
SpaceX gears up for significant 2026 launches while a Starlink satellite anomaly provides insights into its operations.
