There is no alien life on Earth, but there are places that are very similar to its usual habitat. More precisely, these are corners with wildlife, where conditions are radically different from the rest of the planet. It is there, to the active underwater volcano Loihi, that NASA's new scientific submarine SUBSEA will go.
SUBSEA is both a platform for placing specific equipment and an apparatus for studying aggressive environments. We do not know for certain what the icy surface of Saturn's moon Enceladus hides or why the liquid sea of Europa, the moon of Jupiter, does not freeze. It is possible that there are full of underwater volcanoes, and the planetoids themselves and their seas are constantly shaking from the gravitational influence of the gas giants, their masters. In any case, it is dangerous and there are many unknowns.
The first SUBSEA missions will be very simple - to orientate in place, not to die, to find promising sites for study and to carry out an initial inspection. In order for the process to approach cosmic realities, communication will be artificially saturated with interference. First, imitation of the distance - the signal goes to Mars for 12.5 minutes, to Jupiter it takes 33-80 minutes, and you also need to wait for the response. Secondly, sometimes the line will be jammed, as if an area with intense radiation appeared on the way. What does not happen in space.
When the "space submarine" is really able to swim in other worlds, no one undertakes to reason. For example, NASA plans to send a probe to Jupiterian Europe as early as 2020, but there are simply no tools for it to drill 1.5 km of ice and get to liquid water. And where there is liquid on the surface, the use of flying machines seems appropriate for now.
