They were happy and pleased with their performance. That is, unless we decide to protect the area from further erosion by putting a large dome over the entire area as part of an Apollo 12 Landing Site Museum. With only one station left, they were in great shape. The surface times are from Apollo by the Numbers by Orloff. Stretchout also meant that planners, engineers, scientists, and astronauts had more time to assimilate experience and data between missions and, as well, it gave NASA a chance to complete hardware and procedures modification that would make the last few missions spectacularly productive. Pete Conrad and Al Bean had no such weighty matters to restrain them and they hummed and sang and laughed their way from station to station. But this was only the second landing mission and, just as Apollo 12 represented a decided leap in operational complexity over Apollo 11, further leaps were in store. It was only later, during the second EVA, that he and Bean discovered a couple of handy tricks. They had gotten about a half an hour behind the nominal timeline but were otherwise well pleased. Astronauts Charles Conrad and Alan Bean descended to the surface, while Richard Gordon remained in lunar orbit aboard the Command Module. Whitaker had found the crater. And by then, we were wide awake. During the planning stages for Apollo 12, the crater's relative youth made it intrinsically interesting because, among other things, the crater and its ejecta would not have been disturbed very much by later events. There were no disastrous tripping episodes during Apollo 12, but the need to dodge cables slowed the work. Apollo 12 was the second crewed lunar landing. In September 1969, the White House announced that lunar exploration would not continue beyond Apollo 20. He angled north to fly around Surveyor Crater and then south to avoid another, far shallower feature. Conscious of the timeline, they moved quickly from one site to the next and, once they arrived, were in constant motion as they turned to take photographic panoramas, manipulated tools and the sample bags, and did their best to grab rocks without having to bother with the tongs. The two experiment packages tended to bounce up and down as he walked and that made gripping the bar a little difficult; but, generally, he and Conrad had very few problems with this first major set of tasks. Neil Armstrong's quiet reserve versus Pete Conrad's joyful mirth. There were rocks and boulders lying all over the place, some of them up to a meter across, and the astronauts had no trouble filling a bag with representative samples. In recent times - say back over the last few hundred million years or so - most of the tiny impactors have struck the powdery soil itself. At the place where Sharp formed, the regolith was probably deep enough - perhaps 6 to 8 meters - that only a few rocks were brought to the surface. 115:58:28 Another brief view of the Lunar surface during Al's camera move. As he said at the time, he could easily have spent the whole EVA at just one of the stations. They photographed the trench it had dug with its scoop, just in case any part of the wall had collapsed in three years. Avoiding cables was a matter of watching one's feet or, from a more practical point of view, of watching the other guy's feet. The goals of Apollo 12 focused on science, including investigating the lunar surface environment, emplacing the first Apollo Lunar Surface Experiments Package (ALSEP), obtaining samples from a second lunar mare and enhancing the capability for human lunar exploration. However, before such impressive missions could be attempted, NASA had to demonstrate that crews could achieve pinpoint landings, work a full-day in the stiff suits and, if necessary, walk several kilometers back to the LM from a disabled Rover. As he made his second post-landing pass, he put his eye to the sextant in hopes of getting a glimpse of the LM, a feat that Collins had never managed. Recent paleomagnetic studies of lunar rocks have suggested that the magnetic field of Moon reached peak intensities on the order of ≈ 77 μT between 3.85 billion and 3.56 billion years ago (Ga) and subsequently declined to surface intensities of ≈ 4 μT by 3.19 Ga. This was a real puzzle. On the inner slopes, the soil was just as dark as on the surrounding plain; and, based on their observations from the first EVA, the astronauts expected that the footing would remain good as they descended into the crater. Individual Pages- photographed by Ulli Lotzmann on 15 March 2001. "Intrepid, You're Go for EVA. First, it was a reasonably level site. You guys ought to be spring-loaded! Was Houston sure, they asked, that the spacecraft had, like the mock-up they'd used in training, been bright white when it left Earth? The most practical way to grab or manipulate objects close to the ground was to use long-handled tools. They were both relaxed - with heart rates dipping down into the 80s - and Conrad would have whistled while he worked, had whistling been possible at 3.7 psi suit pressure. Indeed, it took several reminders from Houston before they started back to the LM. For the most part, the appearance of lunar soil varies surprisingly little from place to place. When viewed from the approach trajectory, the cluster looks not unlike a Snowman, with Surveyor Crater forming the fat torso. It was he who proved to be the describer of the pair, the one eager to take a close look at just one more fascinating detail or pick up just one more rock. Given enough time and exposure to the rain of small impactors, the Sharp ejecta will become darker and firmer, with each tiny impact creating a bit of dark glass and disturbing the balance of a few grains enough that they tumble into closer contact with their neighbors. Consequently, if they wanted to grip anything smaller than the opening, they had to close their hands against the internal pressure in the suit. Apollo Lunar Surface Experiments Package (ALSEP) deployed. The Apollo 11 Telemetry Data Recordings: A Final Report (0.6 Mb PDF) TV and Communications Documentation Processing and Duplication of Apollo 11 Film, 25 … ", But, of course, Houston wasn't going to keep the explorers waiting long. Firstly, I do realize that this is a rather long video - certainly much longer than any of my other videos on Youtube. The length of the leg could be adjusted with a complex set of laces at the ankle. Like the Surface Journal, it is intended to be a resource for all those interested in the Apollo flights to the Moon, whether in a passing or scholarly capacity. But, then too, Armstrong and Aldrin had to work in an atmosphere of intense public scrutiny, constantly aware of the attentions of a global audience and of history. He is about a third of the way from the Surveyor Crater to the (Snowman's) Head. Hello Everyone. The astronauts from Apollo 11 were Neil Nonetheless, things were going so well and the crew was obviously having such a good time - joking, laughing, humming, and singing - that the lack of a picture was a real frustration to those of us who had taken the Wednesday morning off from school or work to watch the coverage. There it is! Here and there, there are fresher impacts and, at Apollo 12, there are none so fresh as Sharp Crater, a hole about 3 meters deep and 12 meters across which was dug out just a few million years ago by the impact of something about the size of a basketball. Gradually, over four billion years, most of the upper five meters was converted into a fine grained soil. Twenty minutes didn't give them much time for careful consideration or comment; it was very much a matter of jog, stop, take a minute to marvel, take a few pictures, grab a sample, and jog again. Because the suits were pressurized, the glove fingers were necessarily stiff and hard to move. Although Conrad was sure of where he was going to land during the approach, once he was down he wasn't sure exactly where he was. Apollo 12 Surface Checklist including EVA Activities Last revised 4 August 2008. And, finally, Apollo 12 was particularly noteworthy in that Pete Conrad and Al Bean simply had a lot of fun. Unfortunately, while Bean was moving the camera, he pointed it directly at the Sun for several seconds and thereby destroyed the vidicon tube. True, they could only make a sparse record of the work experience and of the adaptation process, but otherwise there were plenty of pictures of the rocks, craters, footprints, and equipment that were of primary interest to the engineers and scientists. This journal covers the flight of Apollo 11 from launch to splashdown. It was a strenuous level of effort but not debilitating and, indeed, they were out on the traverse for more than an hour before they had to take a real rest - and then only because Bean thought, for a moment, that something had happened to his suit. However, on the Moon, the cables hardly seemed to notice the weak gravity and retained loops and bends they had acquired during storage inside the LM - loops that stood up from the ground rather like sections of a frozen garden hose. Bean was ready for a rest, too, commenting that it was the first time during the mission that he'd really "worked up a heart rate". From time to time, the impact of a fair-sized pebble turned a small patch of the surface over, burying some of the powder and exposing fresh fragments to the sandblasting. , they 'd even been sent to the ground was to use tools.
