This animation narrated by lead STS-123 space shuttle flight director Mike Moses depicts the Orbiter Boom Sensor System being mounted on the space station during Endeavour's fifth spacewalk. The OBSS will remain anchored to the station for use by the next shuttle flight, STS-124, which cannot launch with a boom due to its large payload.
