    Preliminary examination of Surveyor 3 components for impact phenomena (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: Two pieces of the Surveyor 3 spacecraft recovered during the Apollo 12 mission were examined for secondary lunar ejecta and micrometeorite impacts. One piece was section E of the aluminum strut; the other was the nickel-coated beryllium television camera mirror.

    Experiment S010: Agena micrometeorite collection (1971)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: A study was made of the micrometeoroid content of the upper atmosphere and the near-earth space environment. Highly polished collection surfaces attached to the target docking adapter (TDA) were exposed to micrometeorite impact and debris collection during the Gemini 8, 9, and 10 missions. Also, the device was attached to the Gemini Agena target vehicle (GATV) during the Gemini 12 mission. The effects of space environment exposure on viable microorganisms were recorded. No substantive data regarding space environment micrometeorite content were derived from the Gemini 9 or 12 missions. However, some substantive data were obtained from the experiment package that was retrieved from the Gemini 10 mission. The micrometeorite-flux values obtained were in general agreement with values obtained from previous experiments by the use of other experimental equipment. The microorganisms that were retrieved from the Gemini 10 experiment package did not survive. However, the same kinds of specimens inside the package had good survival rates. Upon initial analysis, it appeared that the closed-cover shielding was a contributing factor in the protection and survival of the microorganisms.

    Experiment S030: Dim sky photography/orthicon (1971)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: During Gemini missions, the image orthicon system was used to obtain photographic data on faint and diffuse astronomical phenomena. Results show that the photographs may be used to determine the airglow geometry. Although it was sensitive, the original photographic system was unsuitable for use in the study of dim and diffuse astronomical light sources.

    Experiment S012: Micrometeorite collection (1971)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: The micrometeorite activity in a near-earth environment and the effect of the environment on microorganisms were studied by exposure of polished metal and plastic surfaces to the environment outside the Gemini spacecraft. Preliminary results are summarized as follows: (1) The cumulative influx rate in the size ranges from 10 to the minus 15th power to 10 to the minus 14th power gram was approximately 2 particles/ sq m/sec, as determined on the Gemini 12 mission; (2) The cumulative influx rate in the same mass range, as determined by the data from the Gemini 9 mission was almost 200 particles/ sq m/sec; and (3) The large particle cumulative influx rate was about 3 x 0.00001 particle/ sq m/sec, with a mass of the order of 10 to the minus 7th power gram. No living organisms could be found on the sterile collecting surfaces after recovery and handling.

    Stardust. (1972)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: Rocket experiments were conducted to collect particles from noctilucent clouds at Kiruna, Sweden. The Pandora II inflight shadowing technique considered by Hallgren and Hemenway (1971) was used in the experiments. This technique makes it possible to study the collected particles as a function of time and altitude intervals. The particles observed consisted of an irregular electron-opaque core surrounded by a rounded, low density material. X-ray and electron opacity data suggest that the abundances of the heavy elements, such as Hf and Ta, in the particles are comparable to those of the light elements, such as Al and Si.
