NASA TV (originally NASA Select) is the television network of the US space agency, NASA. NASA TV is broadcast by satellite, and also simulcast over the Internet. Many local cable television systems across the US and Canada carry the channel, as do some amateur television repeaters. The station provides a large amount of educational programming, and also covers NASA space launches and missions (such as the space shuttle) live. Analog NASA TV transmissions ceased in late 2005 after the launch of STS-114, ending a period of dual analog/digital transmission, although it may still be available on analog cable TV systems. The satellite link uses the DVB system for data transmission.
