First, you talk to a nervous grunt who is looking at one of the antenae things. He'll say he doesnt know about a storage key and run off. on the spot where he was, there will be a poke-ball. pick it up to receive a storage key. Next, if you go to the left edge of the place where the building is, you will see a green hut. go to the green hut, enter, and use the key on the door. You then go on to battle ALL the people in the building.
You talk to the galactic grunt and he will run away. Then go to the small building to the left and the looker will be there. Follow the looker and getthe galactic key. Now you can get in the door in the galactic building in veilstone.
