The Lobsters had done a quick, primitive job. The three-man crew was crammed into a ribbed lozenge four meters across. It held two air-frames, a recycler, and three acceleration couches, of black elastic webbing over iron frames epoxied to the floor. The rest of the craft was taken up by engines and a garage-like specimen hold. In the hold crouched a surveyor robot, one of the Europan submarine probes.
