After exploring a bit more, we headed back to the Hab to meet a few friends. The NEEMO 4 crew was popping in for a Hab visit. As they descended, they made a stop on the "roof" of the habitat. The distinction between their dive profile and ours was obvious. The top of the Habitat is off limits to us because it's shallower than our saturated dive envelope.

When our buddies finally descended to the depth of the wet porch, we all got a chance to get acquainted. To me, this felt very much the way I imagine an ISS crew changeover must feel, introducing the next NEEMO crew to our now very familiar home. But alas, they were surface divers and had just a short stay with us. Soon they were making their way back to the surface and we were left to take apart the waterlab structure.

It was obvious during the waterlab teardown that we had all been working together as a crew for some time. The task went quickly and efficiently, and we performed the task with simple gestures for communication, even though we had perfectly good radio comm units.

The rest of the day, we enjoyed a little "white space" on the timeline, a bit of undesignated time to catch up on journaling, forms, and other tasks that we had been putting off. It was also a nice time to interact with the whole crew and enjoy the experience of being here together, laughing, looking at video we shot earlier in the day, and quizzing each other on fish identification.

Well, just enough time to grab some food, prepare for a teleconferencing event with Australia, and catch some sleep before our dawn dive tomorrow. Until, tomorrow, signing off.
