The first season of the reimagined science fiction television series Battlestar Galactica, was commissioned by Sci Fi in February 2004.

[2] Following the exodus from the Twelve Colonies, the human fleet has to make an FTL jump every 33 minutes to escape their Cylon pursuers, while the survivors cope with their losses and lack of sleep.

After she confesses to Adama about her role in Zak's death, he feels hurt and angered, but orders her to reinstate the trainees and resume the trainings.

In Galactica's sickbay, Roslin visits doctor Sherman Cottle who confirms her diagnosis of advanced breast cancer and agrees to help procure "Chamalla" extract for her as an alternative treatment.

Commander Adama directs all Galactica's resources to search for Starbuck, but they cannot find her, since the moon has a dense layer of clouds making its surface difficult to see.

Having broken through the Raider's hull, she discovers it is made of living tissue in addition to mechanical parts; Starbuck uses it to replenish her oxygen supply and attempts to repurpose it for crewed flight.

Roslin convinces Adama to call off the search operation after they estimate that Starbuck must have run out of oxygen by then, and agree that the continuing resource spending might endanger the entire fleet.

Roslin informs the entire fleet about the existence of humanoid Cylons, and Commander Adama appoints Sergeant Hadrian to lead an investigation of how Doral got aboard and got access to explosives.

A physical copy of Six appears on Galactica, introducing herself as "Shelly Godfrey" and accusing Baltar of sabotaging the human defenses before the Cylon attack on the Colonies.

Meanwhile, Boomer helps Tyrol make progress in analyzing the Cylon Raider captured by Starbuck, and Roslin temporarily gets sick due to overdoing her anti-cancer medication, causing a brief fleet-wide scare.

The quarrel is resolved after Saul and Adama team up to repel an attack by a Cylon Raider and Baltar completes Ellen's test and declares her human.

Lee Adama and Starbuck arrest a man named Valance who has smuggled a handgun aboard Cloud Nine, the ship where the Quorum meeting is being held.

Battlestar Galactica's first season of thirteen one-hour episodes was ordered by the Sci-Fi Channel on February 10, 2004, with production taking place in Vancouver, British Columbia, Canada.

[3] Produced in 2004 by David Eick and Ronald D. Moore, and starring the original cast from the 2003 miniseries, it began airing in the United Kingdom and Ireland on October 18, 2004.

The website's critical consensus reads, "A captivating combination of riveting political drama and science fiction fantasy make Battlestar Galactica must-see sci-fi.

Writers Ronald D. Moore, Toni Graphia, David Weddle, Bradley Thompson, Carla Robinson, Jeff Vlaming, Michael Angeli, and David Eick take full advantage to give us plotlines that are deeply personal and relatable, while never compromising their affinity and passion for science fiction".

Special features include commentary on the miniseries and "33" by executive producers Ronald D. Moore, David Eick and director Michael Rymer.

Beginning with episode 9, Moore began recording podcast commentaries for the episodes on the official Battlestar Galactica website; Moore provides commentaries for "Tigh Me Up, Tigh Me Down", "The Hand of God", "Colonial Day", "Kobol's Last Gleaming (Part 1)" and "Kobol's Last Gleaming (Part 2)".
