When Apollo was conceived, a lunar landing was considered so difficult that it could only be accomplished through exceptional large-scale efforts in science, in engineering, and in the development of operational and training systems for long-duration manned flights.
The turnaround, docking, and tunnel transfers between the command module and the lunar module were then the same ones that we had planned between the command module and the mission module.
There were displays and controls, backup guidance systems, a lunar landing gear on the LM and an Earth landing system (parachutes) on the CM, and a docking system designed with the precision of a Swiss watch, yet strong enough to stop a freight car.

 Apollo Lunar Landing
The traditional lunar profile was to launch a spacecraft toward the moon, have its landing stage brake it to a lunar landing, then have the ascent stage launch the re-entry capsule from the lunar surface back toward the earth.
James A. Chamberlin and James T. Rose of STG proposed adapting the improved Mercury spacecraft to a 35,000-pound payload, including a 5,000-pound "lunar lander." This payload would be launched by a Saturn C-3 in the lunar orbit rendezvous mode.
Ascent of the LM from the lunar surface, rendezvous, and docking with the CSM in orbit were performed as planned, with docking at 3:36 p.m.

During the second EVA, Conrad and Bean retrieved the lunar module TV camera for return to earth for a failure analysis, obtained photographic panoramas, core and trench samples, a lunar environment sample, and assorted rock, dirt, bedrock, and molten samples.
During the transearth coast, views of the receding moon and the interior of the spacecraft were televised, and a question and answer session with scientists and the press was conducted.
While the lunar module was on the moon, astronaut Worden completed 34 lunar orbits in the CSM operating scientific instrument module experiments and cameras to obtain data concerning the lunar surface and environment.

 Herman Leroy Fairchild: promotor/defender of meteorite impact cratering   (Site not responding. Last check: 2007-10-13)
Craters from known meteor falls were relatively shallow, so lack of experience with major falls tempered the scientists’ imaginations.
Careful analysis of lunar craters and impact cratering experiments confirmed his conviction that lunar craters were of impact origin.
The article stated lunar craters were created by impact and were "ocular confirmation" that "planets were built by cold accretion" which "implies acceptance of the planetesimal hypothesis".

A typical planetary petrology project currently in progress is a study of primitive lunar volcanic glasses, including their origin, processes by which they changed composition, and the eruption process.
The focus of the project was on explosive eruptions at Mount Ranier in the Cascades; the student experimentally determined the phase equilibria of andesitic and dacitic composition magmas involved as well as the rates of Fe-Ti oxide re-equilibration in an attempt to determine the timing of magma mixing, and rates of magma ascent.
We are examining the phase equilibria of granite and pegmatite melts, the dissolution of oxide and silicate minerals into basaltic melts including lunar basalts and meteoritic chondrules, and are investigating the physics of the melting processes.

 RASNZ Occultation Section - Minor Planet News (January 2004 to December 2005)
From then on, the impact cratering record reflects that most objects hitting inner solar system surfaces have been near-Earth asteroids, smaller asteroids from the main belt that are nudged into terrestrial-crossing orbits by a size-selective phenomenon called the Yarkovsky Effect.
Instead of the expected 400 craters as small as 20 meters (about 70 feet) per square kilometer (three-fifths mile) on Eros' surface, there are on average only about 40 such craters.
This finding is important because the cratering record on large asteroids provides direct evidence for the size and population of small main-belt asteroids.

The hypothesis of ordinary chondritic composition for the S-class asteroids is reasonably consistent with the radar data, provided that these asteroids have typical lunar porosities.
In order to evaluate the threat posed by the known Potentially Hazardous Asteroids (PHAs), accurate orbits must be determined for these objects, and future close approaches must be predicted along with their associated uncertainties.
An analysis of probability of detection of binaries among NEAs as well as the statistics of binary craters suggest that roughly 17% of NEAs are binary.

In addition to the "Dawn of Man" prologue, the front-projection system was used to establish scenes of the astronauts walking on the lunar surface.
Onto the background screen was projected a photograph of a miniature set representing the, vast American Moon-base within the crater CIavius.
There is no doubt that the superlative quality of the front-projection sequences in '2001: A SPACE ODYSSEY" will lead to a widespread adoption of the technique within the film industry.

It was lavishly illustrated with real photographs of his plaster model of the lunar surface illuminated at varying angles.
He found that these gave a more realistic impression of the lunar surface than could be achieved with direct lunar photography at the time.
Filters or 'screens' have been used since the earliest days of the telescope, for purposes including the reduction of excessive light, the elimination of spurious color, and the increase of contrast in the image.
