Requests for information

Hello, I am a volunteer of Team FREDNET coordinating communications with Lunarpedia. We regularly need information about the space and lunar environment to support development of our lunar mission, and would be very appreciative if Lunarpedia contributors are able to help us out. I'm adding requests for such information in the list below, in order of importance (most important at top). Not all requests for information are 'mission critical', but in any event it will help draw as complete a picture of the mission environment as possible.--Anders Feder 13:56, 3 January 2009 (UTC)

  • Radiation environment throughout mission. We need a thorough characterization of the radiation environment throughout a mission from the Earth to the Moon, including on Earth, in transit and on the Moon. It must be detailed enough to allow our engineers to design appropriate radiation shielding from the information. --Anders Feder 14:21, 3 January 2009 (UTC)
if you are interested in how to build space hardware for space environments, a good place to start is this book: Space Mission Analysis and Design (Third Edition) (Softback) [James R. Wertz and Wiley J. Larson, eds. - 1999]; 969 pages, 1999, Microcosm/Kluwer; ISBN 978-1881883104 [1];
    Then this: 

Guide to Modeling Earth's Trapped Radiation Environment (Softback) [AIAA - 1999] 55 pgs, 1999, AIAA ISBN 1-56347-349-6

 Then this:
Introduction to the Space Environment (Second Edition) (Softback) [Thomas F. Tascione - 1994]     0445S

Thomas F. Tascione 151 pgs, 1994, Krieger Publishing ISBN 978-0894640445

  • Designers of Apollo RTG's. We have been considering using the SNAP-27 RTG's left by Apollo 12 through 17 on the lunar surface as a heat source during lunar night - even today these radioactive containers still radiate a considerable amount of heat to their surroundings. To determine the feasibility of using the RTG's like that, we would like to get in touch with the original designers of the Apollo SNAP-27 RTG's to ask them about the characteristics of the RTG's on the lunar surface so we can produce a thermal model of the units. We need contact information for these persons. All we currently know is that they worked at General Electric. --Anders Feder 15:50, 4 January 2009 (UTC)
The RTGs are US government property. You will need to discuss their usage with various US federal agencies with jurisdiction, e.g. NOAA, State Dept, DOE, NASA. Technology of RTG will involve ITAR issues which will require export license for non-US citizens. Contacting GE will do no good, they will simply direct you the US federal agencies. Good luck.

  • Regolith composition at Apollo landing sites. The composition of regolith varies greatly with location on the Moon. We need to know the composition of the surface material at our landing site to calculate its frictional properties, which in turn will be used to design our rover. We have not selected a landing site yet, but it will most likely be one of the heritage Apollo landing sites. Hence, we need to know the exact geological composition of the lunar regolith at these sites. Since surface samples were taken by the Apollo astronauts, this information should be available from NASA in some form.--Anders Feder 13:56, 3 January 2009 (UTC)

JSC-1 - Approximately 27,000 lb of JSC-1 simulant is currently available for distribution to qualified investigators. The only cost is for shipping. The material is stored at the Texas A&M Lunar Soil Simulant Laboratory. Investigators desiring a portion of this simulant should address their requests to Dr. Walter Boles, Department of Civil Engineering, Texas A&M University, College Station, TX 77843 (Telephone 409-845-2493, fax 409-862-2800).

Thanks for the links - they have been integrated here and here and here. --Anders Feder 15:44, 4 January 2009 (UTC)
  • Illuminance on the lunar surface. We are trying to figure out how (particularly, how brightly) objects on the lunar surface (not the lunar surface itself) are illuminated at various times of lunar day. We need this information to design visual systems (cameras) for our lander and rover. At least three sources of illuminance has to be taken into consideration: sunshine (light from the Sun), earthshine (sunlight reflected by Earth), and moonshine (sunlight reflected by the lunar surface itself). --Anders Feder 14:14, 3 January 2009 (UTC)
