Hackaday Links: August 23, 2026

We’ll start this week off with some disappointing, though not entirely unexpected, news — the ambitious commercial mission to save NASA’s Neil Gehrels Swift Observatory is officially a bust. The space agency provided an update earlier this week explaining that the attitude control issues with the LINK spacecraft that started a few weeks after it launched will prevent it from being able to safely dock with the Swift Observatory and boost its altitude. As such, the space telescope is now expected to reenter the Earth’s atmosphere and burn up before the end of the year.

Although LINK won’t be able to live up to its name, NASA did say operator Katalyst Space has been given permission to continue with the rendezvous attempt. The two craft won’t actually make contact with each other, but teams on both sides feel there’s lessons to be learned and data to be collected by seeing the orbital dance of these two vehicles play out for as long as possible.

Speaking of hardware that couldn’t quite hit its design goals, TechCrunch is reporting that a class action lawsuit has been filed against Oura by customers that say the company made misleading claims about the sleep-tracking accuracy of their smart rings. Namely, that the rings could somehow detect which stage of sleep the wearer was in with only the pulse and temperature sensors it has onboard.

About a month ago, we brought you word that the commercial rescue mission designed by Katalyst Space to save NASA’s Swift gamma-ray observatory had reached orbit and early indicators were looking good. Unfortunately, it didn’t take long for things to start going sideways, and up until very recently, the situation seemed pretty dire. But according to an interview with Katalyst’s CEO published yesterday by Ars Technica, the company has made some impressive progress on getting things back under control.

For reasons unknown, the robotic vehicle started tumbling out of control last week. Shortly after that, mission controllers lost contact with Swift. After 24 hours without contact from the ground, the spacecraft automatically performed a sort of “hard reset” in an attempt to regain communications. That got it talking again, but somewhere along the way the craft overheated, which in turn cooked the control circuitry for the reaction wheels, which would usually be used to control its orientation. Not great, not terrible.

As of yesterday’s update, we now know that engineers have figured out a way to gimbal the thrust from the craft’s xenon-fueled electric thrusters — which were originally intended for orbit-raising — to counteract its spinning. It’s slow going as these thrusters don’t have a lot of kick, but it seems to be working. We’ll keep an eye on this one and let you know when we know more.

Happy belated July 4th to all the readers from the United States — hopefully you aren’t reading this from a hospital bed after losing a hand or burning off your eyebrows. While we suspect amateur firework shows and their related injuries will be around for many years to come, we did note that many major cities switched over to drone shows this year.

At least on paper, the appeal is obvious. Beyond the fact that drones are safer and quieter than pyrotechnics, they’re also capable of far more complex displays. Good luck trying to draw George Washington’s face in the sky with exploding rockets. But even if it’s a little more than nostalgia, there’s still something about the sights and sounds of fireworks that enthrall audiences. For many, the whole “rockets’ red glare” thing is a bit more meaningful than the “drones’ red LEDs.”

Earlier this week, we brought you news that Sony would stop producing physical PlayStation discs in January 2028. Many gamers are understandably concerned about the long-term implications such a move will have for software ownership, and while the negative reactions online haven’t bothered Sony enough to get them to amend their plans, they have clarified the situation with developers by explaining that games published before the cutoff date aren’t impacted. So if a developer has a hit title that drops in the summer of 2027 and they want to keep cranking out discs, additional orders can still be placed. Not much of a reprieve, but it will give the community a little more time to figure out what comes next.
