PMA3 is soon to be re-located from Unity Nadir to Unity Port (according to the ISS schedule of events thread), so is there to be another swap before Node 3 flies?
And the final location of Cupola is the Port CBM of Node 3 (Tranquality) with the viev squarely on Kibo, yes?

PMA 3 will be re-located early July to the Port CBM of Unity, not be used (according to ISS Scedule of Events thread), then be re-re-located back to Nadir before the middle of December when Node 3 will be attached to the Port CBM?That sounds like nonsense to me.
The Node 3 was originall scheduled for the nadir. Node 1 was plumbed for that position. Node 1 now has to be replumbed with all the power, data, air flow etc to go to the port. To do that we need a pressurized module on the other side of the bulkhead to do the work. PMA3 will be relocated to provide that volume. When done, it will then be relocated back to the nadir.

Node 1 was plumbed for that position. Node 1 now has to be replumbed with all the power, data, air flow etc to go to the port. To do that we need a pressurized module on the other side of the bulkhead to do the work. PMA3 will be relocated to provide that volume. This way, on 20A Node 3 When done, it will then be relocated back to the nadir. Do we have your approval now?
That all makes sense. Always had my approval, just didn't understand (which in itself isn't unusual). Always best to ask?

Why is the change not reflected in the images online?
1. If so, why isn't the MLM being installed first?2. Even if Node 3 has to be installed first, for whatever reason, can't they temporarily mount it on the port side until the MLM arrives, and then move it? They did that with Node 2 due to the need to juggle it and PMA-2.
Boils down to "moving Node 3 temporarily would be a lot more trouble than it's worth."
Quote from: Jorge on 04/17/2009 10:41 pmBoils down to "moving Node 3 temporarily would be a lot more trouble than it's worth."Yes, it seems really not worth of moving this module (to nadir location).Is there also reason to keep Node-3 attached to port CBM of Unity in order to avoid some MMOD risk (I bet that somwhere I heard it earlier).
With Cupola in nadir CBM we have also most clear viev for incomin HTV or Dragon/Cygnus in future. Am I thinking correctly?
I don't know. It might be; the node would be partially shadowed by Kibo and the truss with ISS flying in the TEA attitude.

If there are any Wikipedia editors monitoring, the exploded diagram at the ISS wiki page could use updating as to Node 3 and Cupola location:http://en.wikipedia.org/wiki/File:ISS_configuration_2009-03_en.svg

If you look the line from Node 3 goes round to the port side of Node 1.

Ok, probably a stupid question from a noob so please be forgiving :Knowing full well its too late to make changes, was it ever considered putting Node 3 in the forward CBM of Node 2?
(ie: temporarily putting PMA 2 on the zenith side of Node 2 for shuttle dock, then putting Node 3 in its place. Putting PMA 2 on the forward side of Node 3 but keeping the Cupola on the Nadir CBM for observation)My guess is that it would be hard to relocate PMA 2 with the station's arm. But I honestly don't know. So I'm asking?
Actually, it's not too late. Now that they've decided to leave one of the logistics modules permanently attached, the Node 3 location might go back to Node 2 nadir again. Much discussed on another thread. http://forum.nasaspaceflight.com/index.php?topic=16882.135
USA Today has a nice flashimation on ISS. New to me. Perhaps it has been around a while:http://i.usatoday.net/tech/graphics/iss_timeline/flash.htm

Much discussed on another thread. http://forum.nasaspaceflight.com/index.php?topic=16882.135You mean Node 1 nadir. Node 2 nadir is for MPLM/HLV/Dragon berthings.If I understand it right, there is simply not enough "plumbing" for Node 3 to be at the front of Node 2, and Node 1 nadir or port are therefore prefferable. The Node 3 nadir location will cause some clearance issues at least until the Russian Mini-research Module is berthed at Zarya nadir.
Does anybody know if the Node 3 Umbilical tray in the S0 truss, originally designed for Unity's nadir port location, will be useful now that the Node 3 configuration has been changed to the port side?
Even with MRM-1 located at FGB Nadir, if Node 3 were later moved to Node 1 Nadir, there would subsequently be a very tight fit for Soyuz or Progress to dock with MRM-1, and in the event of an automatic abort, Soyuz or Progress might impinge on Node 3
I don't think the plumbing for the ECLSS etc in node 3 can be arranged for it to be anywhere other than node 1 port or nadir.Please correct me if I'm wrong.

Would there be no way to re-route those connections through the stand-offs* in Destiny & Harmony?
Quote from: Space Pete on 08/16/2009 01:31 amWould there be no way to re-route those connections through the stand-offs* in Destiny & Harmony?No, the issue is getting the resources into the module. The stand-offs just get the resources into the racks
