A new kind of Russian satellite is now in the mix. This satellite, officially known as Kosmos 2589, was launched in June 2025 into a highly elliptical orbit alongside a smaller spacecraft designated Kosmos 2590. The two satellites performed a series of high-altitude rendezvous and proximity operations with one another before Kosmos 2589 began moving toward a more circular geosynchronous orbit, where it arrived in April.
One of the US military’s GSSAP satellites was waiting for it. The US inspector spacecraft is now looping around Kosmos 2589, swinging near the newly arrived Russian satellite twice per day, coming as close as 8 miles (13 kilometers).
What if you have two things? You'd then need two buttons.
The push button is a perfectly viable option, it just needs to be in a form factor that's works. Could be as simple as a tiny low-energy Bluetooth board with a coin battery that will last several months.
All inbound packets are matched against existing sessions. In this case none will turn up, so the packet will go through the "new session" flow and be subject to the same filtering as a bare SYN. Look up how connection tracking works, e.g. in the Linux kernel, it's rather simple and logical.
Looking at all ready-made options on Amazon and elsewhere - anyone who will roll out an adult-oriented well-made single-button camera that takes in standard thermal paper rolls will make a fortune. This is such a great thing to have for get-togethers and parties. But it's essential to not being bound by $X/shot proprietary cartridges and be able to shoot and snap without thinking. Mementos for everyone!
* ... without thinking of costs involved. $2 per polaroid with half of them not even developing properly is a bit too high for spontaneous photography urges.
