Interstellar gas dynamics suggests that energy density of galactic cosmic rays places firm upper limit on undetermined constant of solar modulation
Heavy nuclei intensity in primary cosmic rays, long term solar cycle modulation and time lag in various phases
Two-dimensional diffusion model for gas propagation in lunar atmosphere, discussing contamination by lunar module exhaust gases and solar wind loss mechanism
Study investigates the use of spent launch vehicle stages and modules to support earth orbital operations and functions after successful completion of the primary mission. Emphasis is placed primarily on determination of those uses that afford the greatest utility with minimum possibility of degradation to the primary mission.
Molded plastic preform facilitates the fabrication of small lots of welded cordwood circuits. The preforms retain the components during welding and electrical checkout and facilitate encapsulation of the welded module when used with a conventional potting shell.
Encapsulation technique minimizes embedment and thermal stresses in welded electronic modules. A coating of thinned room-temperature- vulcanizing silicone rubber having a high coefficient of expansion and flexibility at low temperature, is applied first and then an encapsulating epoxy resin having a relatively low coefficient of expansion is added.
