This article will assume some familiarity with narrow phase collision detection methods and associated geometric concepts such as the Minkowski sum. A few years ago I was watching Dirk’s great presentation, The Separating Axis Test between Convex Polyhedra (video, slides). Around the 18 minute mark (slide 29) he starts talking about overlaying Gauss maps of convex polyhedra to find the faces of their Minkowski difference.

China Has Attempted What Might Be the First-Ever Orbital Refueling of a Satellite

wired.com Stephen Clark 2025-08-07 20:30:00

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China’s Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit sometime last week.

The 12-inch version is exceedingly thin and light with a fast-charging battery, and the refreshed form factor looks more premium.
