n a night off, Apollo takes Starbuck, Cassiopeia, and Sheba to one of the least-explored areas of the Galactica - the last of the ancient battlestar's astro-navigational domes, an area Apollo has been repairing in his spare time as relaxation and as an outlet for his passion for deep-star exploration. The dome's scanner is set for long-range communication, and to their surprise they receive a signal, an image of an ancient spacecraft similar to what the Colonies once flew. After showing the signal to Boomer and Commander Adama, they are sent on a long-range Viper patrol to a distant solar system on the transmission's line - and to their horror they discover a Cylon basestar orbiting one of the system's planets in its search for the Colonial Fleet. They escape to the Galactica undetected, and Adama considers avoiding the system, but then decides that he's tired of running and begins preparation to attack the basestar. Apollo recommends infiltrating the basestar to cripple its centralized command chamber before the Galactica attacks, and to their surprise Adama is able to secure information from Baltar, who is allowed to barter knowledge of the Cylons in exchange for freedom, Adama willing to risk that Baltar will also see eventual rescue by the Cylons. The Galactica thus begins its most important mission yet as battle is joined between the ancient battlestar and her Viper fleet against the stronger Cylon raider phalanx of the basestar.
