M. Donahue (2010), Scaling of erosion rate in subsonic jet experiments and Apollo lunar module landings, paper presented at Earth and Space 2010, 12th Biennial Aerospace Division International Conference on Engineering, Construction and Operations in Challenging Environments, Am.

Plant growth in three sources of lunar regolith Fig. 2: Germination and development in the lunar regolith. Full size image Fig. 3: Transcriptome analyses of plants grown in lunar regolith grouped by Apollo site. aThree (Apollo 11) to four (Apollo 12, 17) plants from each site comprised the...
To mark the 50th anniversary of Apollo 11, we revisit a first-hand account of designing the Lunar Module digital autopilot, and compare the approach used then with the way it could be done today.
The two side-by-side photos show a test I conducted with a model of the lunar module and a toy astronaut placed in its shadow as in the Apollo image above. The two photos show the difference between a reflective gray-paper foreground and a less reflective black-paper foreground. Foreground...
This model byO?Brien infers that Apollo astronaut problemsfrom clinging dust, at solar elevations much less than 45 degrees, may havebeen driven by other forces. Mechanical bonding properties intrinsic to lunardust, he suggests, could explain partial success by moonwalkers in sheddinggear of dust ...
Next, the player must land the lunar module on the moon's surface and finally re-enter Earth, ending the journey safely in the ocean. This game can be played on facebook as well. Players can challenge their friends in quests to the moon, recreating the space race between the USA and ...
systems management, lunar module interface, contingency extravehicular activity, lunar-orbit insertion aborts, flight emergency, and crew logs. A Velcro lining allowed it to be stuck in a number of locations around the spacecraft. The paper is fireproof, a provision put into place after the Apoll...
NASA used integrated circuits—the first computer chips—in the computers that flew the Apollo command module and the Apollo lunar module. Except for the U.S. Air Force, NASA was the first significant customer for integrated circuits. Microchips power the world now, of course, but in 1962 t...
s mantle and lithospheric peridotite. In fact, formation of the suite of the lunar Mg-suite lithologies by progressive reaction of mantle-derived liquids with just-formed lithologies may pose fewer challenges than the hybrid-source model, as it requires involvement (physical juxtaposition) of fewer...
The aim of the experiment was to record the seismic waves generated by the eight detonations, as well as the re-impact of the Lunar Module following docking and separation, to study the internal structure of the lunar crust to a depth of several kilometers (Apollo 17 Preliminary Science ...
