A lot depends on what happens in the ISS program and if a real need is identified.And the only real reason I can see is if another module coming up. And that's a BIG if.Well, erm, we do have another module coming up. PLM Raffaello. But that will have its place on Node 1 zenith. I was talking about a module that isn't planned today and will need a place currently not available. Nit (because it's often-repeated): If it goes on Node 1 Zenith, they'll have to move the Z1 truss.

however it will obstruct the viewing area for the cupola, while it will not on node 2 zenith
Node 2 zenith is not an option as I understand the situation for a couple of reasons; the primary one of which is its high MMOD risk. N2z is also the backup placement location for both shuttle MPLM and free flight modules such as HTV should a problem develop with the Node 2 nadir port.

cupola nicely mated and ready...

(they should have several Cupolas spread around the station )

The ISS TEA attitude is pitched down several degrees, so N2 and Destiny provide some MMOD shadowing for N1n. Also, the MMOD flux is higher on the top sides than the bottom.

Wouldn't you rather have the MPLM provide some shadowing for Destiny?

Z1 also has a hatch and vestibule.Of course it wouldn't fit the orbiter, maybe I should use my brain next time. But does the Cupola have a hatch? I can't see where it would fit in an open configuration.
Had no idea Z1 had an pressurized vestibule, always heard is completely unpressurized.
Preparatory to accessing the "dome" volume of the Z1 truss, the crew removed the RED from the Node "ceiling". (RED was temporarily removed from its Node location by disconnecting parts from the hardmount plate, in order to gain access to the dome hatch. Tomorrow, two new and two old support block and pad assemblies will be reinstalled after lubrication. Afterwards the RED will be recalibrated.)The crew then ingressed the Z1 dome and rearranged stowage equipment in the normally sealed space. (This was the second of a three-part stowage reconfiguration aimed at maximizing available stowage space and alleviating some of the current stowage congestion in an effort to improve habitability on ISS. Since there was no pressure inside the Z1 volume, the crew first opened the MPEV (manual pressure equalization valve), and the resulting change in cabin pressure was to verify that there was no leak from Z1 to vacuum before hatch opening. Wearing goggles and dust masks, the crew then opened the hatch and ingressed the space. They removed items approved for stowage into PMA-3 (Pressurized Mating Adapter 3) and then filled the empty space with hardware approved for the Z1 environment. The hatch was closed afterwards.)

N2z is also the backup placement location for both shuttle MPLM and free flight modules such as HTV should a problem develop with the Node 2 nadir port.Actually N2z is perfectly fine. Any place is going to require the PLM to increase its MMOD shielding. Until last week when it was decided to leave Node 3 on N1 port, N2z was the preffered spot for the PLM since it would be close to your visiting vehicles. The crew wants the PLM to be along the axis of the station for efficiency so N2z or N1n works equally well.PLM on N1n does not affect any planned/needed views from the cupola.

CDA? Is this something new or just a change in name following the installation of ATLAS (or whatever the APAS-LIDS adapter is called now-a-days).
