KENNEDY SPACE CENTER, FLA. - NASA Administrator Mike Griffin (left) and HDNet Chairman and President Mark Cuban shake hands after announcing an agreement for HDNet to provide high definition TV coverage of space shuttle launches through 2010. The announcement was made at a news conference held in Colorado Springs, Colo. The news conference was hosted by the Space Foundation during its 22nd National Space Symposium that ended today. HDNet will broadcast the shuttle flights in high definition TV, known as HDTV, which has at least twice the resolution of standard television formats. HDNet also will provide the agency a standard broadcast signal of launches for use by media networks and NASA TV. When possible, it will air HDTV coverage of NASA's expendable rocket launches on its network.
