The “cardinality wall” highlights the data bottleneck as LEO constellations scale to thousands of satellites

As low Earth orbit (LEO) constellations move into an era of concurrency—potentially thousands of spacecraft operating at once—industry is running into a “cardinality wall”: a hidden data management bottleneck tied to tracking and handling the sheer number of objects and connections in near-real time.

Study proposes laser beacons in lunar south-polar permanently shadowed craters for a “lunar GPS” to support Artemis navigation Researchers propose placing laser emitters in the Moon’s permanently shadowed craters to create a local navigation system that can guide future Artemis missions. The concept is framed as a GPS-like capability for surface operations in regions where conventional navigation signals are limited.
