if you could somehow put something into persistent storage on the satellites that causes it to crash every time it tries to start up before it gets to the point where it's able to update the software, then they'd be bricked.

- 0xffff2 1y agoI don't know how Starlink's satellites are architected, but the spacecraft I am familiar with has several different boot images with automatic failover. For that system, you would have to replace/corrupt multiple of the actual boot images to brick the system completely.
- markasoftware 1y agowhat if the boot image itself isn't corrupted but rather there's other persistent data which causes the firmware to get stuck / bootloop? This is more or less what happened to the Mazda head unit firmware in the link I posted.
- 0xffff2 1y agoThere are failsafe images that are fully self contained. I would hope that even Starlink satellites are engineered to a higher standard than an automotive head unit.
