A group of researchers from Caltech <\/strong>and the Jet Propulsion Laboratory<\/strong>(JPL<\/em>) have developed an emergency system for autonomous space vehicles that optimizes diagnostic and response processes in real time, helping to avoid accidents on future space missions.<\/p>\n\n

Safety in autonomous space vehicles at Caltech<\/h2>\n\n

This project was named s-FEAST<\/strong>(Safe Fault Estimation via Active Sensing Tree Search<\/em>), and allows spacecraft to identify and correct problems without human intervention, which is essential in critical situations where there is no time to communicate with Earth.<\/p>\n\n

Professor Soon-Jo Chung’s lab at Caltech has developed s-FEAST technology, an algorithm that simulates multiple possible approaches\/futures in real time<\/strong>, helping spacecraft identify failures and correct them without stopping the mission.\nIt works like a “muscle scanner,” carefully testing spacecraft systems and taking corrective action before major problems arise. <\/p>\n\n

In space, autonomous vehicles can face unexpected challenges<\/strong>, such as propellant failures or collisions with objects, which can jeopardize multibillion-dollar missions.\nSo far, engineers have used redundant systems and safe modes to deal with these problems.\nHowever, these solutions add cost and weight to the spacecraft. <\/p>\n\n

Implementation and execution of tests<\/h2>\n\n

The system has been tested in a multi-spacecraft “dynamics simulator,”<\/strong> where a simulated spacecraft floats over a nearly frictionless surface to mimic space conditions.\nAccording to James Ragan, a Ph.D. student involved in the project, the algorithm quickly analyzes with numerous possible futures, allowing the spacecraft to evaluate“the best trajectory course of action<\/em>” to avoid danger, such as collisions with asteroids. <\/p>\n
