The cable was moved out of range of the cable cutter during Expedition 12 to prevent accidental severing.<\/p>\n Crewmembers tested a manned orbital boom to determine the stability of the Shuttle\u2019s robot arm when equipped with a 50-foot extension. On the end of the arm they performed simulated EVA inspections and repair movements as the arm is moved to various positions while the loads are being measured.<\/p>\n That include \u2018pushing\u2019 against a truss section to test how much loading the boom can handle \u2013 in case of a requirement for the boom to be a work platform for any future TPS (Thermal Protection System) repair work in the future.<\/p>\n Results will be used to develop load-minimizing techniques, worksite stability requirements, and associated hardware in order to accomplish EVA inspection and repair of the Shuttle tiles. **NASASpaceflight.com Job Opportunities**<\/font> <\/font><\/em><\/p>\n <\/u><\/p>\n Astronaunts Piers Sellers and Mike Fossum have completed the opening EVA (spacewalk) of STS-121. The spacewalk saw the astronauts perform Orbiter tile repair worksite stabilization tests \u2013 which appeared to go well, while they also restored one of two failed ISS mobile transporter umbilical guides, and transfered logistics items. **STS-121: Launch: July 4 Launch\/Debris\/Flight Day 1** \u2013 […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[2],"tags":[],"class_list":["post-42011","post","type-post","status-publish","format-standard","hentry","category-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts\/42011"}],"collection":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/comments?post=42011"}],"version-history":[{"count":0,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/posts\/42011\/revisions"}],"wp:attachment":[{"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/media?parent=42011"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/categories?post=42011"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/starpath.global\/blog\/wp-json\/wp\/v2\/tags?post=42011"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
