TRACKING WITH CLOSEUPS: Tearing Down a Starlink User Terminal
"...you have to cough up $500 for the hardware and another $100 a month for the service. Despite the fairly high bar for getting your hands on one, [Kenneth Keiter] decided to sacrifice his Starlink dish to the teardown Gods."https://t.co/P1LhJoq82w

It doesn’t appear that you can realistically get into the exceptionally thin antenna array without pulling it all apart, thanks in part to preposterous amount of adhesive that holds the structural back plate onto the PCB. The sky-facing side of the phased array, the key element that allows the antenna to track the rapidly moving Starlink satellites as they pass overhead, is also laminated to a stack-up comprised of plastic hexagonal mesh layers, passive antenna elements, and the outer fiberglass skin. In short, there are definitely no user-serviceable parts inside.

CONTINUITY: Hayabusa-2 Sample Capsule Recovered in Australia
Capsule collection! The helicopter team immediately flew to the location identified by the DFS team. They searched for the fallen capsule by using radio waves and maps. Thank you very much!

Why Australia? Because Japan is a long, skinny country with little east-west extent, varied terrain, and dense vegetation. The Australian outback is a much larger target and an easier place to find the capsule when it comes down.
