The Antares arrives at Venus and Zoe and Donner prepare to travel down to the planet on the landing craft, the Crossbow. With only 20 minutes to collect the Gamma object and return, the mission may have to be aborted when the Crossbow lands too far from the planned landing site. At Mission Control, Rollie is still upset over the accident. Journalist Trevor Williams keeps working on Arnel Poe to reveal what he knows about the Venus mission. Claire sends Evram Mintz the information she has on the transformation the crew is undergoing. In flashbacks, the final 20 candidates for astronaut training are revealed and the list doesn't include one of the current crew members.
