troisième segment bâbord de la poutrelle

OBS: La séquence d'assemblage des poutres bâbord (P1, P3, P4, P5, P6) et tribord (S1, S3, S4, S5, S6) de la Station spatiale internationale diffère habituellement de l'ordre de numérotation des éléments structuraux de la grande poutrelle. Dans le cas présent, la poutre P5 correspond au troisième segment bâbord de la poutrelle.
OBS: troisième segment bâbord de la poutrelle : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

CONT: The US space shuttle delivers the third port truss segment, the P5 Truss, to attach to second port truss segment, the P3/P4 Truss.
CONT: This truss segment, called ""S5,"" is a mirror image of the P5 truss segment that arrived for processing at Kennedy Space Center in July 2001. The S5 truss segment is a 10-1/2-by-15-foot aluminum structure that will weigh 3,900 pounds when fully processed ... Items to be attached to the S5 truss include handholds to be used by spacewalking astronauts, a strut assembly, multi-layer thermal blankets, and the installation of the PVRGF.
CONT: The P5 and S5 segments are merely spacers that will provide enough room for the solar arrays to track the sun and not interfere with the other equipment, for example, the waste-heat radiators and antennas. The waste-heat radiators attached to segments S1 and P1 also must be clear of array movement.
