Ben Bova 
Titan 

Titan Alpha has landed: the most complex man-made object to reach Saturn’s largest moon. The ten thousand men and women of Habitat Goddard are once more at the frontier of science. From their huge, artificial paradise hanging in orbit above Saturn, some of them dream of landing on Titan’s surface. Others will do anything to prevent such a landing. And yet others have darker, secret plans. But almost immediately, Titan Alpha goes silent. And minor, inexplicable faults start to affect Goddard. Is there a basic design flaw that could threaten the lives of everyone on board? Or has one of the many malcontents exiled to space decided to sabotage the probe or even the whole expedition? The newest chapter in Ben Bova’s epic of space exploration brings to vivid, awe-inspiring life a barren world of swirling smog, frozen methane seas – and perhaps even a new sentient life form.
