Paul Delaney, senior lecturer and director of the Division of Natural Science in the Faculty of Science & Engineering, spoke to CTV News May 14 about the space shuttle's current mission to the international space station. Crews are conducting space walks, loading equipment and bringing back experiments that have been running on the space station's 'porch' -- an outside laboratory in the vacuum of space.

The video is available on CTV's Web site.
