Is the shuttle damage boom compatible with CanadaArm2?

You never know; it might come in handy.&nbsp; Perhaps after the last mission they could leave it behind like they will after this mission. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

As they will do now with STS-123 when they are leaving the boom to the station. Of course they have to do it earlier and they ar not able to scan every place at the same resolution as undocked, but if that is not a problem now why it should be one at the last mission?<br /></p> <div class="Discussion_UserSignature"> </div>

<p>I have to imagine it would be possible to develop some kind of adaptor to connect the OBSS Canadarm linkage with the Canadarm2 end effector. Just as the OBSS is used to looking at thermal tiles for damage, that extra reach and the sensor package would be valuable for remotely looking at sections of the station for damage and for other purposes.</p><p>Yes, it might take a little time to build, but I imagine that the long-term benefit would ultimately make it worthwhile, as seen in the solar array repair situation.&nbsp; Also, its relatively small size would make it easy to add as minor payload to a future shuttle mission, or (if small enough) send it up with a future Progress, ATV or H-II craft.<br /> </p> <div class="Discussion_UserSignature"> </div>

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&nbsp;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.&nbsp;<img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-smile.gif" border="0" alt="Smile" title="Smile" />&nbsp;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>
