Welcome to Edition 8.02 of the Rocket Report! It's worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

Sizing up Europe's launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent's incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar's Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA's ministerial council meeting in November, when ESA member states will set the agency's budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We're on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX's blistering Starlink launch cadence. We discuss the topic of megaconstellations in this week's Rocket Report.

So, what is SpinLaunch doing now? Ars Technica has mentioned SpinLaunch, the company that literally wants to yeet satellites into space, in previous Rocket Report newsletters. This company enjoyed some success in raising money for its so-crazy-it-just-might-work idea of catapulting rockets and satellites into the sky, a concept SpinLaunch calls "kinetic launch." But SpinLaunch is now making a hard pivot to small satellites, a move that, on its face, seems puzzling after going all-in on kinetic launch and even performing several impressive hardware tests, throwing a projectile to altitudes of up to 30,000 feet. Ars got the scoop, with the company's CEO detailing why and how it plans to build a low-Earth orbit telecommunications constellation with 280 satellites.
