NEWS SPAZIO :- Si è svolta ieri la seconda ed ultima attività extraveicolare EVA-2 prevista dalla missione STS-133 dello Space Shuttle Discovery .
I due "spacewalker" impegnati sono stati ancora una volta Steve Bowen and Alvin Drew, protagonisti anche di EVA-1 .
Una piccola perdita nella tuta di Bowen riscontrata durante i controlli antecedenti all'EVA ha leggermente movimentato i preparativi. Una volta riparata, EVA-2 ha potuto iniziare. Erano le ore 10:42 a.m. EST (16:42 ita).
Drew has emptied the ammonia remaining in the pump that was replaced during EVA-1, which is now ready to return to Earth (in a future mission) to be analyzed.
Anchored to the station's robotic arm (SSRMS) Boewn recovered a LWAPA (Lightweight Adapter Plate Assembly) used to attack payload of experiments outside the European Columbus laboratory. LWAPA has moved to Discovery's cargo bay to be brought to Earth.
Meanwhile Drew has removed the insulation from the group of avionics Express Logistics Carrier-4 (ELC-4) and moved a sunshade on the lens of a camera located near ELC-4 itself (because it obscured the view).
Bowen has installed a Light Camera Pan and Tilt Assembly (CLPA) in robot Dextre and removed the insulation is not necessary.
Drew then installed a lamp in the CETA (Crew Equipment Translation Aid) and attacked an insulating to a line of flow of a valve in the radiator left side of the Truss.
Bowen finally mounted a camera lens cover to the coupling of the "elbow" of the robotic arm that will protect the SSRM slow erosion that could be caused by the jets produced by rocket thrust for future space vehicles that si agganceranno alla Stazione.
In totale EVA-2 è durata 6 ore e 14 minuti. Ecco il video
