While all U.S. households will soon be transitioning to digital TV, the International Space Station team has been busy, having recently filmed a high-definition tour of the orbiting complex. Expedition 18 Commander Mike Fincke, aboard the International Space Station with Flight Engineers Sandy Magnus and Yury Lonchakov, recently filmed a 35-minute tour that will air as a special Video File on NASA Television's HD Channel 105 at 1 p.m. and 3 p.m. CST Thursday and Friday, January 22 and 23.

The special Video File also will be broadcast in standard-definition on NASA TV immediately following the regularly scheduled daily Video File broadcasts. For technical information on how to receive the special broadcast in high definition, and for NASA TV streaming video, downlink and scheduling information, visit this site.

With a mass of almost 630,000 pounds, the station has grown to a size larger than an average four-bedroom house on Earth. The next space shuttle mission, designated STS-119, will continue the station's assembly by delivering a fourth and final set of solar arrays. Shuttle Discovery and its seven-member crew are targeted to launch February 12.
