Europa Submersible Probe
A remote-controlled submersible probe
pokes around beneath the icy mantle of Europa. The probe is designed to
fit down a narrow hole, with the lights mounted on deployable rods, and
small motorized wheels mounted on the fairings (hard to see here).
Antennae trail behind. Power and warmth are provided by a SNAP
generator near the rear. Stereo cameras are in front. Water intakes
for chemical analysis are behind the front fairing. Attitude control is
provided by small thrusters. Main propulsion comes from a small propellor equipped with a Kort nozzle.
The oceans of Europa and the other Galilean moons could prove to be the most surprising environments in the solar system.
