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.

As always, we welcome reader submissions . If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

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 into 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.

OpenAI today announced a significant expansion of ChatGPT's customization and memory capabilities. For some users, it will now be able to remember information from the full breadth of their prior conversations with it and adjust its responses based on that information.

This means ChatGPT will learn more about the user over time to personalize its responses, above and beyond just a handful of key facts.

Some time ago, OpenAI added a feature called "Memory" that allowed a limited number of pieces of information to be retained and used for future responses. Users often had to specifically ask ChatGPT to remember something to trigger this, though it occasionally tried to guess at what it should remember, too. (When something was added to its memory, there was a message saying that its memory had been updated.)

Remember when teachers demanded that you "show your work" in school? Some fancy new AI models promise to do exactly that, but new research suggests that they sometimes hide their actual methods while fabricating elaborate explanations instead.

New research from Anthropic—creator of the ChatGPT-like Claude AI assistant—examines simulated reasoning (SR) models like DeepSeek's R1 , and its own Claude series. In a research paper posted last week , Anthropic's Alignment Science team demonstrated that these SR models frequently fail to disclose when they've used external help or taken shortcuts, despite features designed to show their "reasoning" process.

(It's worth noting that OpenAI's o1 and o3 series SR models deliberately obscure the accuracy of their "thought" process, so this study does not apply to them.)
