Today's briefing covers a DARPA award for Redwire's innovative satellite project, Ursa Major's expansion in defense engines, a Rocket Lab military test flight, and more.
How a California startup's massive centrifuge could transform space access by eliminating rocket fuel, reducing costs by 70%, and enabling daily satellite launches - if it can overcome the physics of scaling from suborbital tests to orbital reality
Starship receives FAA approval for its next test flight, while SpaceX prepares to launch more Starlink satellites amidst reaching 5 million subscribers.
Pentagon cancels Next-Generation OPIR Polar program after Northrop Grumman delivered sensor payload. LEO and MEO alternatives deemed sufficient for missile-warning coverage.
SpaceX has been active, with successful launches of Starlink satellites and major developments at Cape Canaveral, signaling a competitive edge in satellite communication and launch capabilities.
In 2024, China launched 68 orbital missions. In 2025, the number jumped to 97. In 2026, state media and Western analysts agree the target is 140 or more. Most of that growth is being driven by two state-backed mega-constellations, a half-dozen private launch companies hitting stride, and a deliberate national pivot toward commercial space. Beijing is no longer trying to catch SpaceX. It is trying to build an industrial base that outlasts one.
SpaceX launched Starlink batches from Vandenberg and Cape Canaveral within 48 hours, pushing the active constellation toward 10,000 operational satellites.
The UK's orbital ambitions rest on a remote Shetland island. How SaxaVord became Europe's first fully licensed vertical launch spaceport - and why, despite being ready for years, it's still waiting for a rocket that works.
