I have always been fascinated by robots. We have a lot of robots in the present day but, the usage of robots and AI to perform various tasks for humans.
Yes, you might have heard of the curiosity rover robot which is currently searching for life and liquid water on mars. In a similar way nasa has developed various prototypes and plans to build robots which travel through icy oceans. WHY ICY?
Well, we have many planets which are in the habitable zone. In some cases, they might even have water on their surface. But, they might have icy surfaces underneath them.
so, it’s a lot like curiosity only, it’s having special tools to crack through and collect samples through the hard ice.
