<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Exactly, on both points. However, I've not heard whether or not the OBSS keep-alive systems are going to be left in place on the station after STS-124, or if they will be discarded.As for the adaptor, the issue likely isn't internal volume of the transporting spacecraft, but whether it could be engineered to fit through either the smaller Progress/ATV hatch or the larger PMA/H-II hatch. Either way, I don't see a way that such a piece of equipment could be taken directly from the interior of the cargo ship to the station exterior...it must be navigated through the station to an airlock, or sent up with a shuttle towards end-of-flight. <br />Posted by Huntster</DIV></p><p>I don't believe that the size of the adapter would be a problem... And if it is there is always a possibility to use H-II nonpressurized cargo bay which probably has bigger hatches.</p><p>What comes to that keep-alive, that one is not probably a big problem... If I have understood correctly the boom is only "taped" to the struss and one single cable from the struss camera connector to the boom is feeding the power. Of course this thing has to be someting more usable if the boom is permanently stored to the station because with this way they will need EVA every time when they want to use the boom. I guess that those connectors are not designed to be handled with Dextre and there is a 90 minute thermal window to re-power the boom.</p><p>Please remember that I'm not a professional ISS/shuttle geek. <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-smile.gif" border="0" alt="Smile" title="Smile" /> I only try to put all the things here which I think I have red or heard at sometime/someplace...</p> <div class="Discussion_UserSignature"> </div>
