Building a Mechanical Star Tracker for the ISS
2025-01-18
Engineer Ted Kinsman was tasked by NASA astronaut Don Pettit to design and build a mechanical star tracker for capturing high-quality astrophotography images from the International Space Station (ISS). Due to the lengthy testing period for electronic devices, the tracker was entirely mechanical, cleverly utilizing a clock drive from an industrial oven. Gear ratios were adjusted to match the ISS's orbital speed. The device successfully reached the ISS in 2024 and has captured stunning images of the cosmos.
