Latest Space Station Tour, Experiment To Be Broadcast In HDTV

NASA Television will broadcast a high-definition tour of the International Space Station recorded by the Expedition 20 crew starting at 10 a.m. EDT on Wednesday, June 24. Also broadcast in HD will be an explanation of a Canadian experiment on the station that examines how humans perceive up and down without gravity as a reference.

The 20-minute tour, which documents the full 167 feet of the space station's pressurized modules, was recorded by NASA Flight Engineer Michael Barratt to show Mission Control how equipment and supplies are arranged and stored, and to provide engineers with a detailed assessment of each module-to-module hatchway.

A five-minute explanation by Canadian Space Agency Flight Engineer Bob Thirsk provides an overview of the Bodies In the Space Environment, or BISE, experiment. The experiment looks at the relative contributions of internal and external cues that allow humans to orient themselves in the absence of gravity. The principal investigator for the BISE experiment is Laurence R. Harris, of York University, North York, Ontario, Canada.

The NASA Television HD feed (Channel 105) will broadcast the items every hour on the hour, beginning at 10 a.m. The videos also will be broadcast in standard-definition format on the NASA Television Public and Media Channels VideoFile beginning at 10 a.m.
