Despite some issues with the&nbsp;stance Tyurin suffered from, he managed to get one shot off \u2013 out of a potential three.<\/p>\n<p>Work on&nbsp;what proved to be a troublesome&nbsp;antenna on a recently arrived Progress re-supply ship was worked on next. The antenna was found to be jammed next to a handrail.<\/p>\n<p>Attempts to move it back into a stowed position \u2013&nbsp;including use of a crowbar \u2013 failed.&nbsp;Remote signals from Russian controllers also attempted to aid the movement of the antenna, but that also failed.<\/p>\n<p>Also scheduled on the spacewalk&nbsp;was the jettisioning of two thermal covers from an experiement housed on the outside of the Station.<\/p>\n<p>This part of the EVA raised concerns that they may interfere with Shuttle Discovery\u2019s orbit during STS-116 next month, but the problem was noted too late for the schedule to be changed.<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">A special meeting was called just this morning, where concerns were raised over where those covers would end up in orbit, which \u2013 it was claimed \u2013 may still be in a conflicing orbit with the soon-to-arrive Shuttle Discovery on STS-116.<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018In a special meeting this morning, the IMMT (ISS Mission Management Team) discussed the possibility that two of the items to be jettisoned during the spacewalk may not have decayed at the time of STS-116\/12A.1 arrival, \u2013 both soft thermal covers of the BTN-M1 experiment,\u2019 noted today\u2019s ISS On Orbit Status Report.<\/p>\n<p>\u2018With a mass of 500 gram&nbsp;and 200 g and dimensions ~320\u00d7300 mm &amp; ~200\u00d7200 mm, respectively, their orbital lifetime will depend on their (unpredictable) orientation after being thrown overboard (most likely: tumbling; least likely: stable at max cross section i.e. max drag).\u2019<\/p>\n<p>However, the meeting also concluded that changing the plan for the EVA was too late to implement. Managers will rely on tracking the covers, with&nbsp;future evaluations being carried out on a potential conflict with the upcoming Shuttle mission.<\/p>\n<p>\u2018Since Moscow has determined that the EVA cannot be modified this late for retrieving the covers on board or temporarily stowing them outside, the IMMT approved the jettisoning with the proviso that attempts are to be made.<\/font><\/p>\n<p><font face=\"Arial\" size=\"2\">\u2018(Those provisions are:&nbsp;(a) obtain a maximum amount of data from Space Command tracking, (2) capture video of the jettisoning without repositioning of the SSRMS, and (c) use the data to put together a risk probability to support the 12A.1 launch decision in two weeks&nbsp;\u2013 there is no concern about ISS recontact.\u2019<\/p>\n<p>Near the end of the spacewalk it was confirmed that the two covers were actually jettisoned during this spacewalk.<br \/><\/font><br \/><font face=\"Arial\" size=\"2\"><img loading=\"lazy\" decoding=\"async\" height=\"60\" alt=\"\" hspace=\"5\" src=\"http:\/\/forum.nasaspaceflight.com\/forums\/get-attachment.asp?action=view&amp;attachmentid=12993\" width=\"468\" align=\"left\" vspace=\"5\" border=\"0\"><\/font><\/p>\n<p><em><font face=\"Arial\" size=\"2\">**INFINITY: 10 minute&nbsp;STS-115 MUSIC&nbsp;VIDEO**<\/font><\/em><font face=\"Arial\"><font size=\"2\"><em>&nbsp;\u2013 <br \/><\/em>(<em>Video section is FREE, but you need to sign up as a member of the forum to enter the video section of the site.
