NASA's Miniature Robots Dive into Europa's Oceans for Life Hunt

NASA is testing cellphone-sized underwater robots, known as SWIM (Sensing With Independent Microswimmers), for future missions to search for life in the oceans beneath the icy surface of Jupiter's moon Europa. These robots, tested in a swimming pool at Caltech, are designed to autonomously explore and detect chemical and temperature signals that might indicate alien life. The prototypes are equipped with multi-sensor chips and wireless communication systems, and engineers are optimizing their design through simulations. Europa is considered a promising location for finding extraterrestrial life due to its vast subsurface ocean.
