Drift Happens

The video, produced by Dr. Robert Hodson, NASA Avionics Technical Fellow, uses AI-generated voice to explain the critical challenges of distributed time synchronization in space avionics, illustrating how tiny timing errors can cause mission failures, such as the scrubbed STS-1 launch and navigation issues on Mars Rovers, and discusses both logical and physical clock solutions, fault-tolerant architectures, and the ongoing need for robust synchronization as humanity explores deeper into space.
