ISS Module Relocation 2015

In preparation for future Crew and cargo vehicles in 2017, the ISS will have a new Module Relocation and the addition of a new docking system, the International Docking Adapters 1 and 2. These IDA 1 and 2 will fly on SpaceX Dragon CRS-7 and CRS-9 respectively, and will be installed on both PMA-2 and PMA-3.
Currently, the station has one usable port for docking, the PMA-2 located on the forward end of Node 2 “Harmony”. The other PMA-3 is on the port side of Node 3 and it is inaccessible for docking. The IDAs will be attached to the PMAs and will convert their APAS interfaces into new interfaces to be used by all future commercial crew vehicles.

On May 27, 2015, the Permanent Multipurpose Module “Leonardo” will be relocated from the Earth facing port of Unity (Node 1) to the forward port of Node 3 “Tranquility”. At the present time, Node 2 zenith (top port) is currently designated as the back up berthing port, with the primary port being Node 2 Nadir (Earth facing port).
When PMA-3 is moved to Node 2 zenith, then the backup berthing port will no longer exist. To solve this issue, the PMM Leonardo needs to be relocated in order to free up Node 1 Nadir port (Earth facing port) for cargo vehicles. This is the reason why this new module relocation needs to take place.
This graphic representation is an overview of the PMM relocation.

The following photos show my ISS paper model in a sequence to represent the new module relocation.

With respect with the ISS paper model, the PMM Leonardo module needs to be carefully detached from the nadir port of Node 1 “Unity” and to be attached to the forward port of Node 3 “Tranquility”.

  1. I think it is really great you keep mutating your ISS to all the changes happening in real life. Especially because with all the photos you clearly show what is about to happen. These things should actually be able to be picked up by NASA or Space.com to demonstrate the events in detail from all those different angles.
    Great stuff, Alfonso And very educative as well. Thanks!

    • Thanks PK. Yeah, as long the station is still orbiting above us, I’ll try to keep up with all the updates. I feel frustrated each time I see that NASA and other agencies don’t show in detail all these changes for the common citizen. People are more interested in learning about the daily life of celebrities and gossip than science.

    • Hi Devon. This relocation of the Leonardo logistics module was not originally planned, and it was only in the last few years that a decision was made to open a new back up port for commercial vehicles.
      When I designed the ISS model, I mentioned that the Leonardo was to be glued to the nadir port of Unity module. So most of the people who have bought this model will encounter the problem in removing this piece without causing major damage to the rest of the model.
      And I am no exception. I carefully was able to remove the Leonardo that was originally glued. With an X-acto knife you should be very careful in trying to remove the model. Depending on how much glue you put in you will be able to remove it completely or not. You can always make a new module anyways.

      Once you have Leonardo rebuilt or removed, then glue it to the Node 3 module following the photos I uploaded on my blog.
      Be prepared with the PMA-3, too. This will eventually be relocated on top of the Harmony module.
