Vintage, 2019. — Vintage eISBN 978-0-307-81648-1.A group of scientists (psychologist Norman Johnson; mathematician Harry Adams; zoologist Beth Halpern; astrophysicist Ted Fielding; and marine biologist Arthur Levine), along with U.S. Navy personnel, travel to a deep sea habitat at the bottom of the Pacific Ocean, where an enormous spacecraft has been discovered.During the descent, the marine biologist (Levine) becomes claustrophobic, and is returned topside. The other scientists arrive safely at Habitat DH-8. After their arrival and subsequent pressurization to the habitat's exotic-gas environment, the Navy sends a robot to enter the spacecraft first, which locates and opens a panel near the spacecraft door.As the robot's cameras focus on the opened panel, labels in English indicate the spacecraft is a U.S. spacecraft constructed in the future and sent through time, appearing on the seabed at least 350 years before its creation. The robot is unable to open a hatch leading further inside, forcing the team to don pressure suits and explore the spacecraft. In a large cargo hold, the team discovers a mysterious spherical object that is clearly of extraterrestrial origin.
