From Wikipedia, the free encyclopedia
NASA TV (originally NASA
Select) is the television network of the United States space
agency, NASA. NASA TV is broadcast
by satellite with a simulcast over the Internet. Local cable
television systems across the U.S. and amateur
television repeaters
may carry NASA TV at their discretion, as NASA-created content is
considered a work of the U.S. government and
is in the public
domain. The network was formally created in the early 1980s to
provide NASA managers and engineers with real-time video of
missions,[2][3]
and NASA has operated a television service since the beginning of
the space program for archival purposes and to provide media
outlets with video footage.[4]
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 to digital
transmission in late 2005 following the launch of STS-114, ending a period of
dual analog/digital broadcasting, although some cable television
systems may still have transmitted in analog prior to the United
States digital transition. The satellite link uses
the DVB-S system for
transmission.
Channels
The NASA TV network operates four channels, both over the air
and online. The Public Services 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 schools, museums, and other educational institutions. The
Media Services 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, encrypted feed for NASA spaceflight
operations.[5][2]
NASA also provides an online-only channel featuring continuous live
footage from the ISS, broadcast as part of the 10th anniversary of
the station in orbit.[6]
Programming
NASA TV airs 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; "NASA Edge" and "NASA 360", hosted programs
that focus on different aspects of NASA; and "This Week @ NASA",
which shows news from NASA centers around the country. Live ISS
coverage and related commentary is aired daily at 11 a.m. EST and
repeats throughout the day.[7]
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, Josh Byerly, Nicole
Cloutier and Brandi Dean.
Canadian
broadcasting
Prior to 2007, the
Canadian Radio-television and Telecommunications Commission
(CRTC) prohibited NASA TV from being aired by local satellite and
cable systems, with the exception of specific broadcast events.[8]
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.[9]
Awards
In 2009, NASA TV received two Emmy Awards. 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.[10]
On August 22, NASA TV was awarded a national Primetime Emmy, the 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.[11][4]
