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
