Atmo Suit won't deliver to rocket

Is the rocket complete? Is there a gantry to access it? 

Yes to both.  I can load my astronaut and unload him but I still can't deliver the atmo suit.

Wow, it's indeed a challenge. I use your save game and do the following:

1. Click on Priority Button [P] and change all priority 9 to 8. This change does not intervene your current game play but may take times to change all of them.
2. Click on Command Capsule and raise its priority number to 9.
3. Open Priority Screen [L] and temporary disable all chore for Catalina (or a dupe that you like). Then, raise priority level of storage chore (the furthest column) to highest level (up-up).
4. Click on Catalina. Her info will pop-up. Then, click on "Move to" Button and order her to come closer to an atmo suit on floor (near Exosuit Forge).
5. Wait and pray that she will pick a suit and go straight to the rocket before downtime. If she goes somewhere else, there may be some priority 9 somewhere that need to be changed to 8. Just click on her and click on "Follow Cam" to see where she is heading to, decrease its priority and repeat step 4-5 again. 
6. After a successful delivery, open Priority Screen [L] and change Catalina's chore back to normal and revert all priority 8 to 9 (I would suggest leaving them at 8).
