Life-Hunting Robot Probes
The moons of Saturn and Mars are nevertheless full of potential closer to home. Even while we haven't yet found evidence of life, it doesn't imply there isn't more to learn. Additionally, more effective methods of discovery will raise our odds.
The notion of sending probes to moons like Europa and Enceladus that can be pushed below the ice we are aware is there to explore for indications of life has been investigated by NASA. Robots might be placed in the liquid water beneath the ice and given free reign to swim wherever they like to explore what they can see.
This is only one example of a future smart probe that can search and then decide for itself if it has discovered anything worthwhile. They may employ artificial intelligence to aid in their search and analysis because signals from space take a while to reach Earth. They would only report back when they think they have discovered something significant.
