'''NASA TV''' (originally '''NASA Select''') is the television service of the United States government agency [[NASA]] (National Aeronautics and Space Administration). It is broadcast by [[satellite television|satellite]] with a [[simulcast]] over the Internet. Local cable television providers across the United States and [[amateur television]] [[repeater]]s may carry NASA TV at their own discretion, as NASA-created content is considered a work of the U.S. government and is within the public domain. NASA TV is also available on a few broadcast television stations. The network was formally created in the early 1980s to provide NASA managers and engineers with real-time video of missions.<ref name="dcp0709" /><ref name="ndtv" /> NASA has operated a television service since the beginning of the space program for archival purposes, and in order to provide media outlets with video footage.<ref name="nasapr090820"/>

The network airs a large amount of educational programming, and provides live coverage of an array of manned missions, including the [[Space Shuttle]] and [[International Space Station]] (ISS), robotic missions, and international launches. The network completed its conversion from [[analog television|analog]] to [[digital television|digital]] transmission in late 2005 following the launch of [[STS-114]], ending a period of dual analog and digital broadcasting, although some cable television systems may still have transmitted in analog prior to the U.S. [[Digital television transition in the United States|digital television transition]]. The satellite link uses the [[DVB-S]] system for transmission.

==Channels==
[[File:NASA TV truck.JPG|left|thumb|180px|NASA TV broadcasting truck]]
NASA TV operates four channels. The "Public Channel" provides 24-hour broadcasting of live and recorded events and documentaries aimed toward the general public. The "Education Channel" provides space and science programming for [[school]]s, museums, and other educational institutions. The "Media Channel" is dedicated to broadcast news organizations and other members of the press, featuring press release video, interviews, mission press conferences and other services. The final is the "Space Operations Channel", an internal, [[encryption|encrypted]] feed for NASA spaceflight operations.<ref name="dcp0709"/><ref name="ntv-digital"/> A [[high-definition television|high definition]] simulcast feed of the "Public Channel" was launched on July 19, 2010.<ref name="hdtvmag100715"/>

The NASA TV website also provides a channel featuring continuous live footage from inside and outside the ISS, established to celebrate the 10th anniversary of the station in orbit,<ref name="ntv-iss"/> as well as a continuous audio-only channel of ISS and Shuttle mission audio.<ref name="ntv-audio"/>

==Programming==
NASA TV carries a variety of regularly scheduled, pre-recorded educational and public relations programming 24 hours a day on its various channels. Programs include ''NASA Gallery'', which features photographs and video from NASA's history; ''Video File'', which broadcasts [[b-roll]] footage for news and media outlets; ''Education File'', which provides special programming for schools; ''This Week @ NASA'', which shows news from NASA centers around the country; and ''[[NASA Edge]]'' and ''[[NASA 360]]'', hosted programs that focus on various projects and activities within NASA. Live ISS coverage and related commentary is aired in hour-long segments throughout the day.<ref name="ntv-programming"/>

The network also provides an array of live programming, such as 24-hour coverage of [[Space Shuttle]] missions, ISS events (spacewalks, media interviews, educational broadcasts), press conferences and rocket launches. These often include running commentary by members of the NASA Public Affairs Office who serve as the "voice of Mission Control", including Rob Navias, Nicole Cloutier, Brandi Dean, and formerly, [[Josh Byerly]].

==Canadian broadcasting ban==
Prior to 2007, the [[Canadian Radio-television and Telecommunications Commission]] (CRTC) prohibited NASA TV from being aired by local satellite and cable providers within Canada, with the exception of specific broadcast events. Under existing CRTC rules, a cable or satellite provider had to offer a minimum amount of programming from companies owned and operated by Canadians. Additionally, CRTC stated in September 2000 that there simply was not enough room left under the analog television [[frequency allocation]] scheme, and standards for dealing with foreign [[digital television]] signals had not been finalized.<ref name="space000920"/> On April 20, 2007, the Commission issued a notice stating that after receiving an initial request from [[Mountain Cablevision]] and support from other Canadian broadcasters and members of the public, NASA TV had been added to the lists of eligible satellite services.<ref name="crtc"/>

NASA has used external companies to provide streaming services for internet viewers, both embedded into NASA's website and through streams branded by those companies. The variety of stream formats used have varied with the available technology and with the popularity of formats, including [[RealMedia]], [[QuickTime]], [[Windows Media]], and [[Flash Video]].

In July 2005, NASA entered into an agreement with Yahoo! and [[Akamai Technologies]] to provide streaming services for NASA TV ahead of the [[STS-114]] mission and associated Return to Flight program after the [[Space Shuttle Columbia disaster|Space Shuttle ''Columbia'' disaster]].<ref name="nasa05-182"/> {{As of|2015}}, NASA has entered agreements with [[Ustream]] to provide high definition streaming of NASA TV and high definition cameras aboard the International Space Station, along with mission audio. Archives of press conferences, [[NASA Social]] events, and other events are also made available via UStream.<ref name="ustreamagree"/> Other NASA TV programs and events are archived via the NASA TV YouTube channel.

==Awards==
In 2009, NASA TV received two [[Emmy Award]]s. On January 24, the Midsouth Chapter of the [[Academy of Television Arts & Sciences]] awarded NASA TV and the [[Marshall Space Flight Center]] with the Governor's Award for Lifetime Achievement in recognition of NASA's 50th anniversary.<ref name="nasapr090122"/> On August 22, NASA TV was awarded a national [[Primetime Emmy Award]], the [[Philo T. Farnsworth Corporate Achievement Award|Philo T. Farnsworth Award]], for engineering excellence in recognition of the 40th anniversary of [[Apollo 11]]'s first television broadcast from the surface of the moon.<ref name="nasapr090820"/><ref name="space090820"/>
