NASA is going to use swarms of drones to search for alien life. We're getting close.

NASA is developing swarms of drones to search for signs of extraterrestrial life. The agency is planning to use a combination of autonomous drones and AI algorithms to search for signs of life on other planets. The drones will be able to navigate through environments that are dangerous or difficult for humans to access, such as swamps or caves, and will be able to collect and analyze samples of soil, water, and air. The AI algorithms will be able to process the data collected by the drones and identify signs of life, such as the presence of certain chemicals or patterns of behavior. (Source: NASA)
