During the Television Critics Association winter press tour, it was confirmed History renewed Project Blue Book for a second season with 10 episodes. The UFO drama was considered as one of the most-watched shows on the channel to date, and while there were only a few details about the second installment, here are some of the details revealed regarding Project Blue Book season 2 so far.

Project Blue Book follows the story of astrophysics professor Dr. J. Allen Hynek (Aidan Gillen) who teamed up with Air Force Captain Michael Quinn (Michael Malarkey). The History series focuses on top-secret investigations about Unidentified Flying Objects (UFO) and other related phenomenon covered by the United States Air Force back in the 1950s and 60s. The series is reportedly based on real events.

At the moment, the release date of Project Blue Book season 2 hasn't been announced. But, many speculated the second installment will likely arrive in January 2020, since the preceding season premiered on the same month. The trailer of the first season was also released in July of last year, so it's possible the trailer of the season 2 will be revealed on the same month as well.

The final episode of Project Blue Book season 1 titled "The Washington Merry-Go-Round" showed the Washington, D.C. UFO incident occurred in 1952, wherein different sightings were recorded from July 12 to July 29. Based on the ending of the first season, Dr. Hynek has likely adopted a ufologist frame of mind and Gillen indeed confirmed this concept, as per the report from IGN.

Thus, the second season will not only focus on actual events, but it will also use a creative license for dramatic purposes. So, the life of Dr. Hyneks will be more complicated while looking beyond perceived truths just to understand the larger picture. The plot of Project Blue Book season 2 will be more expansive, as well as focusing on Dr. Hynek's evolving character arc.

Aside from Gillen and Malarkey, other cast members expected to return on the second season include Robert John Burke as William Fairchild, Neal McDonough as General James Harding, Ksenia Solo as Susie Miller, Michael Harney as General Hugh Valentine, as well as Laura Mennell as Mimi Hynek.

Meanwhile, the renewal of the second season arrived amid strong ratings of the show, with an average of 3.4 million viewers per episode - making Project Blue Book the most-watched new cable show of the 2018-19 season to date. Produced by A+E Studios along with Compari Entertainment, the series' executive producers are Robert Zemeckis, Jack Rapke, and Jackie Levine. Sean Jablonski serves as the showrunner, executive producer, and writer, while David O'Leary is the creator, executive producer, and writer.
