Spaceship to Saturn

The length of the trip to Saturn means that the crew will undergo 'hypothermia' for the duration of the flight, however a massive increase in meteor activity around Saturn threatens to cancel the mission as the computer on Earth will be unable to manoeuvre the craft at such long distances to avoid collisions. The solution - instantaneous telepathy; twins Gill and Gail maintain a telepathic carrier-wave even under hypothermia which can be modulated to carry telemetry. A landing is attempted on Titan but problems arise requiring the ship to be flown through the Cassini division, a narrow gap in the rings of Saturn...
