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.

Expedition 61 Crew, Record-Setting Astronaut Christina Koch Return to Earth

Expedition 61 Commander Luca Parmitano of ESA (European Space Agency), Soyuz commander Alexander Skvortsov of Roscosmos and NASA Flight Engineer Christina Koch landed safely on Earth near the town of Dzhezkazgan, Kazakhstan, Feb. 6 after bidding farewell to their colleagues on the complex and undocking their Soyuz MS-13 spacecraft from the Poisk Module on the International Space Station. Koch completed a 328-day, 139-million mile mission on the orbital outpost --- the longest spaceflight ever conducted by a woman in history and the second longest single spaceflight by a U.S. astronaut. Parmitano and Skvortsov wrapped up a 201-day mission in space spanning 85.2 million miles.

Launching Americans from U.S. soil, sending a new rover to Mars and continuing to prepare for human missions to the Moon are just a few of the things NASA has planned for 2020.

Pioneering NASA mathematician Katherine Johnson has died at the age of 101. Johnson was part of a group of African-American women who worked on critical mathematical calculations in the early days of human spaceflight, as chronicled in the best-selling book and hit movie “Hidden Figures.”

"She was an American hero and her pioneering legacy will never be forgotten,” said NASA Administrator Jim Bridenstine.
