Slow train to Arcturus

Description:

Sending a spaceship to rendezvous with an enormous vessel made up of a series of globular habitats approaching its star system, the aliens find a savage race calling themselves "humans" who promptly slaughter the exploration team, except for a single survivor who escapes to another habitat, where he finds more friendly humans whose help he requires to get back to his own ship.
