The ESS Charybdis was a 21st century Earth spaceship operating under the auspices of NASA. It was the third manned attempt to travel beyond the Sol system. It was the tenth in the series of Odyssey spaceship launches. (ST short story: "The Immortality Blues")
With the crew in hibernation chambers, the ship travelled towards the Theta 116 system. The ship's computer woke Colonel Richey nine days before reaching Theta 116 VIII, but he let the rest of the crew sleep as part of the mission was to gather information on long-duration habitation. During the mission, the communications system malfunctioned and all attempts to repair it proved futile.
