    Probing the solar plasma with Mariner radio tracking data (1971)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: The range and Doppler radio tracking close to the sun made it possible to measure solar plasma dynamics. These were measured by means of a method known as differenced range versus integrated Doppler, which exploits the opposite change of group and phase velocity as the plasma density changes along the radio raypath. A simple solar plasma propagation model is proposed.

    Cosmic ray experiment. Part A: Composition and energy spectra of solar cosmic ray nuclei (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: The GE experiment consisted of two types of detectors: plastics and glasses located in panel 2 and the lower half of panel 3. In panel 2, the entire exposed detector area of 14.7 by 22.6 cm was composed of 31 sheets of 0.025-cm polycarbonate plastic 9070-112. In panel 3, 39 sheets of 0.02-cm cellulose triacetate with no plasticizer made up the major volume fraction. The lower part of panel 3 contained five types of glass detectors. Particles that entered the array after it was folded were recognized, if they crossed from one sheet to another, by means of a 2-mm relative shift of alternate sheets.

    Composition of interplanetary particles at energies from 0.1 to 150 MeV/nucleon, part B (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: During the Apollo 16 mission, a solar flare produced an enormous amount of low-energy nuclei, many orders of magnitude greater than the level inferred from studies of tracks in the window of the Apollo 12 spacecraft during a time when the sun was quiet. The differential energy spectrum of nuclei with Z less than or equal to 6 falls by seven orders of magnitude over the interval from 0.1 to 20 MeV/nucleon, then remains almost flat up to approximately 100 MeV/nucleon. The two parts correspond to contributions from the sun and from galactic cosmic rays. Any maximum in the spectrum occurs below the lowest energy studied.

    Solar cosmic ray, solar wind, solar flare, and neutron albedo measurements, part C (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: All mineral detectors exposed on Apollo 16 had high surface track densities probably produced by a solar flare that occurred during the mission. The heavy ions followed a power law spectrum with exponent approximately 3 down to approximately 200 KeV/nucleon. The abundance of low-energy particle tracks observed in this flare may explain the high track densities observed in lunar dust grains. Pristine heavy-particle tracks in feldspar give long tracks. Shallow pits similar to those expected from extremely heavy solar wind ions were observed in about the expected number. Initial results give a low apparent value of neutron albedo relative to theory.

    Pulse performance analysis for small hypergolic propellant rocket engines (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: Small rocket engine tests were conducted for the purpose of obtaining pulse performance data to aid in preliminary design and evaluation of attitude control systems. Both monopropellant and hypergolic bipropellant engines of thrust levels from 5 to 445 N (1 to 100 lb) were tested. The performance data for the hypergolic propellant rockets are compared with theoretical performance calculated from idealized chamber filling and evacuation characteristics. Electromechanical delays in valve response and heat transfer characteristics were found to cause substantial deviation between theoretical performance and test performance. The theoretical analysis is modified to obtain a semiempirical model for hypergolic propellant rockets.

    Extendible rocket nozzle development (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: An evaluation is presented of J-2 engine modifications that will simplify operation and improve reliability of the advanced Saturn 1C launch vehicle. Methods of increasing thrust without extensively modifying the S-2 or S-4B stages are also evaluated. A thrust increase was achieved by raising engine combustion through a redesign of the engine thrust chamber and propellant feed system.

    Solar flares, the lunar surface, and gas rich meteorites (1972)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: Investigations on the Fe-group nuclei track density vs depth in lunar rocks and Surveyor 3 TV camera filter glass were critically examined considering more factors than previously. The analysis gives a firmer basis to the observation of the preferential leakage of low energy Fe nuclei from the accelerating region of the sun. The track density gradients in lunar rock 12022 and filter glass are used to determine the lunar erosion rate of 3 angstroms/yr. Track gradients are less steep than predicted from energy spectrum observed in the Surveyor glass, perhaps due to sputtering. High densities of etchable tracks were found at all depths down to 60 cm in fines from Apollo cores and also in thin sections of the Pesjanoe, Pantar, and Fayetteville gas-rich meteorites. It is felt unlikely that suprathermal heavy ions were responsible for the high track densities.
