Noah Wyle and his Falling Skies castmates better get used to fighting aliens because it looks like they may be doing it for awhile.

Falling Skies debuted on June 19th with a two-hour episode that attracted 5.9 million viewers and a 2.0 rating in the 18-49 demographic. The second episode fell to 4.2 million and a 1.5 demo rating. Last Sunday’s installment fell again to 4.1 million viewers and a 1.4 demo but those numbers were understandably depressed because of the holiday.

Regardless of the decline, TNT has faith in the series and has now ordered a second season of 10 episodes. They’ll kick off next summer.

Here’s the press release:

TNT Orders Second Wave of “Falling Skies,” Cable’s #1 New Series

Epic Series from DreamWorks Television and Executive Producer Steven Spielberg, Starring Noah Wyle, Scores as Major Hit in U.S. and Abroad

TNT has renewed Falling Skies, cable’s #1 new series, for a second season. The epic saga about the aftermath of an all-out invasion by an alien military force has been a tremendous hit both domestically and internationally. Falling Skies, which airs Sundays at 10 p.m. (ET/PT), stars Noah Wyle and comes to TNT from DreamWorks Television and executive producer Steven Spielberg. TNT has ordered 10 episodes for the second season, which is slated to air in summer 2012.

“Falling Skies is a true standout series, from its ambitious storytelling, high-profile cast and production team to its phenomenal success when it comes to international and time-shifted viewing,” said Michael Wright, executive vice president, head of programming for TNT, TBS and Turner Classic Movies (TCM). “We’re reaching new audiences with Falling Skies and look forward to seeing where this fascinating and exciting series takes us next.”

Falling Skies takes place in the chaotic aftermath of an alien attack that has left most of the world completely incapacitated. Tom Mason (Wyle), a Boston history professor and the father of three sons, must put his extensive knowledge of military history to the test as second in command of a regiment of resistance fighters protecting a large group of civilian survivors. Falling Skies also stars Moon Bloodgood, Will Patton and Drew Roy.

Falling Skies premiered in the U.S. on TNT Sunday, June 19, drawing an extraordinary Live + 7 audience of 8 million viewers and ranking it as cable’s top series launch of 2011. The premiere also garnered an impressive 3.8 million adults 18-49 and 4.5 million adults 25-54. Through its first three installments, Falling Skies has averaged more than 6.4 million viewers through a blend of live and time-shifted viewing.

Falling Skies is quickly becoming a global television sensation. In the opening stages of its rollout in more than 75 international markets, it has already drawn strong – and in some cases record – audience deliveries for networks airing it in the United Kingdom, Spain, Germany, Argentina, Brazil, Chile, Colombia, Mexico and Venezuela.

In addition to Spielberg, the first season of Falling Skies has been executive-produced by DreamWorks Television heads Justin Falvey and Darryl Frank, Graham Yost and screenwriter Robert Rodat, who wrote the pilot from an idea he co-conceived with Spielberg. Mark Verheiden and Greg Beeman have served as co-executive producers.
