Stanford Engineers Teach Spacecraft to "Dream" Their Way to the Space Station
Docking with the ISS may seem simple. However, actually doing so is a showcase in how difficult orbital mechanics can be. It’s equivalent to traveling down a highway at 28,000 km/hr and parallel parking into an open garage on a multi-billion dollar laboratory traveling at the same speed. If you try to accelerate forward you actually drift up, and there’s no air friction to naturally slow you down. Oh, and if you hit the lab, everyone onboard both your craft and the station dies, and the resultant debris field could both wipe out dozens of satellites and even people on the ground. No pressure, obviously. For decades, aerospace engineers have been docking successfully using hard coded physics equations and human pilots to correct them. But now, a new paper, available in pre-print on arXiv from researchers at Stanford, is taking a shot at building an AI to perform a series of “mental simulations” that could fundamentally change how future spacecraft interact with each other.
