Moonshot: The Inside Story of Mankind's Greatest Adventure (36 page)

After being given permission to stay on the surface, Neil explained to Mission Control why he had taken his time to land: 'Hey, Houston, that may have seemed like a very long final phase. The auto-targeting was taking us right into a football-field-sized crater, with a large number of big boulders and rocks for about one or two crater diameters around it, and it required us going in [computer program] P66 and flying manually over the rock field to find a reasonably good area.' Meanwhile, in Houston, Joan Aldrin was passing round cigars when the TV coverage switched to a press conference being given by Janet. Deciding she ought to do the same, Joan left the revellers in her front room to join the reporters waiting outside.

Much still needed to be done before Neil and Buzz could begin to relax. Soon after landing, they vented the descent engine's fuel tanks to prevent a dangerous build-up of vapour pressure. Since a leaking fuel tank on the ascent stage or a failure in their oxygen supply could force them to return to orbit sooner than planned, the next priority was to update their guidance systems with
Eagle
's position relative to the stars. Releasing the cables holding him in position, and removing his helmet and gloves Buzz peered through
Eagle
's alignment telescope. Determining relevant angles relative to specific stars, he updated the two computers. 'The first two hours on the lunar surface were, for me, the busiest part of the flight,' Buzz later said.
⁷
Neil tried to establish whereabouts they were on the ground. The navigation error they had encountered at the start of PDI had been stretched by his decision to fly virtually straight and level as they dodged the craters at the end of the flight. They had a rough idea of where they were, but neither the crew nor Mission Control could establish a precise position.

Armstrong: 'Houston, the guys that said that we wouldn't be able to tell precisely where we are, are the winners today. We were a little busy worrying about program alarms and things like that in the part of the descent where we would normally be picking out our landing spot. And aside from a good look at several of the craters we came over in the final descent, I haven't been able to pick out the things on the horizon as a reference as yet.'

Mission Control: 'Rog, Tranquility. No sweat. We'll figure out ... We'll figure it out. Over.'

Later, it was established that they had come down nearly four miles further west than expected. The landing site was roughly a third of a mile beyond the 'football-field-sized crater' that the radar had been bringing them towards. During their training this had been informally called West Crater. At some point in the Moon's history it had been gouged out of the landscape after a meteoroid smashed into the surface, creating an explosive force that had sent broken chunks of rock in all directions. Some could be seen through Buzz's window, away to the right of the spacecraft, while closer to the LM lay many smaller rocks, several up to three feet across.
⁸
Craters of all sizes lay everywhere, ranging from one to 100 feet wide. But the feature that dominated the landscape was the layer of dust blanketing the ground, which Neil compared to 'very fine silt'.
⁹
By making detailed assessments of what the surface looked like, the men were outstripping the capabilities of the Surveyor probes before they had even stepped out of the spacecraft. The LM was facing west, and while they could see ahead and much of the ground left and right, they couldn't look directly behind them, back towards the Sun.

Armstrong: 'The area out the left-hand window is a relatively level plain, cratered with a fairly large number of craters of the 5-to 50-foot variety; and some ridges which are small – 20, 30 feet high, I would guess; and literally thousands of little 1- and 2-foot craters around the area. We see some angular blocks out several hundred feet in front of us that are probably 2 feet in size and have angular edges. There is a hill in view, just about on the ground track ahead of us. Difficult to estimate, but might be a half a mile or a mile.'

Mission Control: 'Roger, Tranquility. We copy. Over.'

To Neil, the surface appeared warm and inviting. 'It looked as if it would be a nice place to take a sunbath,' he later remembered. 'It was the sort of situation in which you felt like going out there in nothing but a swimming suit to get a little sun.'

Still passing across the near side, Michael Collins in
Columbia
had heard the exchange of transmissions during the landing. Twenty minutes after touchdown, he was encouraged by Neil's first impressions of the surrounding area.

Collins: 'Sounds like it looks a lot better than it did yesterday at that very low sun angle. It looked rough as a cob then.'

Armstrong: 'It really was rough, Mike. Over the targeted landing area, it was extremely rough, cratered, and large numbers of rocks that were probably some – many – larger than 5 or 10 feet in size.'

Collins: 'When in doubt, land long.'

Armstrong: 'That's what we did.'

Safely on the ground and reflecting on what had happened, Neil's heart-rate was now registering in the 90s; during the landing it was in the region of 150 beats per minute. While he continued to describe what he could see, Aldrin worked on the guidance systems. Now that they were on the surface they could see fewer stars than when coasting through space, and to enhance the accuracy of the updates Buzz used an estimate of vertical based on gravity.
¹¹
Other tasks also demanded attention.
Eagle
's mission timer was suggesting they had been in space for 902 hours, and after trying to reset it Houston asked the crew to vent the fuel tanks again.

At 3.59pm, 103 hours and 27 minutes into the mission, radio contact with
Columbia
was suddenly lost as the command module began its fifteenth orbit. For the first time on his own, Michael slipped behind the far side of the Moon. 'I am alone now,' he later wrote, 'truly alone, and absolutely isolated from any known life. I am it. If a count were taken, the score would be three billion plus two over on the other side of the Moon, and one plus God only knows what on this side.' Coasting through shadow, for 48 minutes Michael lay beyond the reach of any other human being. Gazing out of the window he could see nothing but stars; in the darkness even the Moon itself was concealed from him. Enveloped by a sense of freedom and peace, Collins regarded it as a magical experience that he described not as solitude but characterised more by a sense of confidence, 'almost exultation'.
¹²

While waiting for the command module to return overhead, Neil and Buzz carried out a simulated countdown. All being well, this would serve as a rehearsal for the launch scheduled for the following day, although if they got into difficulty and needed to blast off as soon as possible they would be well prepared. The countdown was timed to reach zero upon
Columbia
's return. This moment would be their third opportunity to leave the Moon earlier than planned, but again it wasn't needed. As Mike passed above it was clear that Armstrong and Aldrin would be staying where they were for a while longer yet, and they began to power down the LM.

Aboard
Columbia
, Collins approached the landing site from the direction of the Sun. Coasting at more than 3,600mph, 60 miles above the Sea of Tranquility, it took him just 13 minutes to pass above the general area of the landing ground. Before vanishing over
Eagle
's western horizon, Michael used the sextant to look for the LM. By entering map co-ordinates into his computer, he hoped the sextant would be automatically aimed at the right spot on the surface. But the instrument was fitted at a steep angle and the presumed landing site crossed its field of view for just two minutes, giving him little time to find the LM. Houston later gave Michael new co-ordinates to check, and on each successive pass he searched up to two grid squares on his map, together totalling a square mile or so. Houston was giving him areas that were ten grid squares wide, and in the little time available he saw nothing but craters.
¹³
While coasting overhead, Collins could talk directly to Neil and Buzz, but once he sailed beyond their line of sight he relied on Houston to connect him. Of course, as soon as he passed round to the far side, Michael could talk to nobody.

During this period, Collins climbed out of his pressure-suit. By detaching the centre couch and placing it to one side, he made it easier to get in and out of the lower equipment bay where the sextant was installed. Turning up the lights and moving freely in the spacious cabin, Michael knew that TV commentators would be suggesting he was the loneliest man 'since Adam'. He didn't agree, and later wrote that 'Far from feeling lonely or abandoned, I feel very much a part of what is taking place on the lunar surface.'
¹⁴

On the ground, the crew agreed to skip a four-hour rest period, following an idea they had discussed before launch. There had been concerns that it might take time to adjust to one-sixth gravity. But Neil felt they had done this remarkably quickly, and he advised Houston that the EVA would now begin in about three hours' time, at around 8pm.
¹⁵
The rest period had been included in the flight-plan partly to soak up any delays caused by technical difficulties. If the crew had lost time after the landing in dealing with a problem they might still have been able to begin the EVA on schedule. But since reaching the surface, Armstrong and Aldrin had not encountered any serious problems. They had the Moon at their feet and were keen to explore its surface.

Before preparing to leave the spacecraft they took their first meal break since breakfast, ten hours earlier. For Buzz this was an opportunity to pause and consider the almost unbelievable position they now found themselves in. After seeking the advice of Reverend Dean Woodruff, Aldrin had decided that at this point it would be appropriate to celebrate Holy Communion, and had agreed this in advance with Deke.
¹⁶
A leading atheist had taken NASA to court after the reading from Genesis by the Apollo 8 crew, consequently Slayton had advised Buzz not to broadcast the Communion text. Taking the wine and chalice from his personal preference kit, Aldrin read from a small card as he addressed Houston and the millions of people listening at home. 'This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. Over.' Buzz then took Communion in silence, the wine slowly swirling around the chalice in the Moon's low gravity.

Neil was left to his own thoughts, which soon he too would be sharing with the world. Only after they landed did he decide on what he would say once he stepped on to the surface.
¹⁷

When they were ready, the men broke into the snacks they had brought with them and tucked into a brief cold meal. With empty food trays adding to the clutter in the cabin, they now found themselves up against an unexpected problem. In Houston, EVA training sessions had always begun with everything ready to hand. Now, their cramped cockpit was strewn with cameras and magazines, checklists and flight-plans and bulky equipment for extra-vehicular activity – and everything had to be either prepared for use on the surface or else stowed away.
¹⁸
In case the timer could not be restarted, Neil decided to leave his watch in the cabin rather than wear it during the EVA.
¹⁹
(Astronauts were given a standard-issue Omega Speedmaster Professional manualwind watch, but Buzz considered it not up to the job.
²⁰
) Tidying up the cabin, setting up cameras and retrieving kit from lockers, they took their time preparing everything carefully, wanting to get as much done as possible before they had to strap on their bulky backpacks.

Returning across the near side, Michael was trying to listen to their preparations. Later he said that the role of the command module at this point in the mission was to 'act like a good child and be seen and not heard'.
²¹
In single-handedly maintaining his position in orbit, and providing the closest thing Neil and Buzz had to a rescue agency, Collins himself was taking part in a testflight. Armstrong later said, 'I think Mike's view, and I share it, was that his responsibility was to prove single-man operation of the command module – a very complex piece of machinery – for the first time, for an extended duration, and in conjunction with a spacecraft on the ground. He needed to demonstrate communications procedures and many other things.'
²²
The dialogue between Houston and
Eagle
was initially transmitted to
Columbia
, but when Buzz complained that the relay signal was interfering with the LM's transmissions Houston switched it off. After losing contact with Tranquility Base, Michael felt 'somewhat cut out of the loop'.
²³
Later he also inadvertently lost contact with the ground, and by the time the link was restored he was ready for something close to a chat.
