Magnificent Desolation_ The Long Journey Home From the Moon - Buzz Aldrin [14]
We wanted to get these descriptions on the record as early as possible, should we for any reason have to make a hasty departure. More than anything, however, we wanted to get out there and explore the moon’s surface for ourselves.
THE PREPARATION TO go outside was complex; finalizing our suiting-up process from our visor-protected helmets down to our overshoe moon boots would alone take us several hours in the cramped space of the Eagle. With just enough room to maneuver, Neil and I helped each other one at a time to put on the 185-pound life-support backpacks, still large and cumbersome even with their lunar-equivalent weight of thirty pounds in the one-sixth gravity. We switched over our life-support connector hoses from the onboard supply of oxygen and electricity to the backpack, fully equipped with its own electrical supply, water connector, communicator, and oxygen inlets and outlets. With no air on the moon, and plenty of heat from the sun and cold in the shadows, our suits and backpacks were truly our life-support system, a 100-percent fully contained living environment. In them, we had cooling provisions in our underwear, thanks to an ingenious system of plastic tubing, about 300 feet worth, that could circulate the ice water that was being produced by the backpack. We had electrical power and enough oxygen for four hours, and antennae connections for radio communications between Neil and me, but also so our conversations could be heard back on Earth. On top of our large backpacks, we had an additional emergency supply of oxygen in a separate container, in case we needed it while on the moon, or for an emergency EVA spacewalk upon re-docking with Columbia after liftoff from the moon.
Since we were ahead of schedule, we took our sweet time, making sure that everything was correctly in place. That we weren’t rushed helped us to relax as we anticipated venturing out onto the surface. I remember, right before cabin depressurization, a passing thought I voiced as I put on my helmet, which ended up on the transmission to Houston: “Sure wish I had shaved last night.” I was about to walk on the moon for a one-night stand on a stage before the world, so appearances were on my mind! In final preparation, Neil glanced at a printed checklist attached on his left wrist and forearm, facing inside just above his gloved hand, that would remind him of the tasks he had to perform during our short time on the moon. I had a similar checklist sewn onto my suit.
When Neil and I had completed connecting all of our life-support equipment, and had made sure all our systems were functioning correctly, we depressurized the Eagle’s cabin so we could open the door to the outside world. I watched carefully as the gauge eased down to zero. I attempted to reach down and open the hatch, but it wouldn’t release. The cabin still wasn’t quite empty of oxygen. Amazingly, just a tiny bit of oxygen pressure would keep that hatch from opening inward. I made a mental note of that, since I would be the last man out of the LM. If there was any oxygen remaining in the Eagle when I stepped out, and the hatch should close, we’d have a hard time getting back in our ride home. The
