Direct from America's space program to YouTube, watch NASA TV live streaming here to get the latest from our exploration of the universe and learn how we discover our home planet.

NASA TV airs a variety of regularly scheduled, pre-recorded educational and public relations programming 24 hours a day on its various channels. The network also provides an array of live programming, such as coverage of missions, events (spacewalks, media interviews, educational broadcasts), press conferences and rocket launches.

In the United States, NASA Television's Public and Media channels are MPEG-2 digital C-band signals carried by QPSK/DVB-S modulation on satellite AMC-3, transponder 15C, at 87 degrees west longitude. Downlink frequency is 4000 MHz, horizontal polarization, with a data rate of 38.86 Mhz, symbol rate of 28.1115 Ms/s, and ¾ FEC. A Digital Video Broadcast (DVB) compliant Integrated Receiver Decoder (IRD) is needed for reception.
