Scientists Proposed a Nuclear 'Tunnelbot' to Hunt Life in Europa's Hidden Ocean

A group of scientists wants to send a nuclear-powered "tunnelbot" to Europa to blaze a path through the Jovian moon's thick shell of ice and search for life. [...] On Friday (Dec. 14) at the 2018 meeting of the American Geophysical Union, the researchers presented a proposal for a "tunnelbot" that would use nuclear power to melt a path through Europa's shell, "carrying a payload that can search for... evidence for extant/extinct life."

The tunnelbot, the researchers reported, could use either an advanced nuclear reactor or some of NASA's radioactive "general-purpose heat bricks" to generate heat and power, though the radiation would present some design challenges.

Once on the frozen moon, the tunnelbot would move through the ice, also hunting for smaller lakes inside the shell or evidence that the ice itself might contain life. As it burrows deeper, it would spit out a long fiber-optic cable behind itself leading up to the surface and deploy communications relays at depths of 3, 6 and 9 miles (5, 10 and 15 kilometers). Once it reaches the liquid ocean, to keep from "falling through," it would deploy cables or a floatation device to lock itself in place, the researchers wrote.

      Our wage is in watt/hours. Fail delivering a sufficient amount and we literally won't lift a finger anymore...
