chunk: At first, the Sunbird's commander refuses to communicate with them, suspicious of their motives. As they continue to plead with the astronauts to accept their rescue offer, the men are chilled to hear their mission referred to in historical terms. They come to realize that they were not only thrown off-course in space, but in time as well, and that their flight was lost centuries ago. They are given bare details of the current Earth: an undefined cataclysm has reduced the human population to a mere few million. Eventually, the Sunbird agrees to rendezvous with the spaceship Gloria to allow the astronauts to spacewalk to safety.
  The Gloria is an enigma to them. Besides having an almost all-female crew, the ship is haphazard and cluttered with plants and animals on board. None of the technology seems very advanced and some of the ship's functions are powered by stationary bikes. Their culture shock is compounded by the cryptic and incomplete answers they are given concerning the Earth.
