Axial tension and compression are transmitted between end fittings and fiberglass tube without depending on glass-to-metal bonding, conventional fasteners or combination of these things. Joint design significantly reduces both structural weight of strut and its cross-sectional area.
Calculated curves are presented for the intensity of the scattered solar Lyman alpha radiation as it would be observed at various distances from the sun by a deep space probe during the late 1970s and early 1980s. Near the sun, most of the neutral gas, and hence the emission maximum, is in the pole direction. At 2 AU from the sun, the maximum is quite broad. At greater heliocentric distances, most of the emission lies between the probe and the sun; thus, the angle which the emission maximum makes with the pole increases steadily as the probe moves out.
Calculation of the angular dependence of the intensity of solar Lyman alpha resonantly scattered from neutral interstellar hydrogen which has penetrated the solar system. A simple model which essentially neglects temperature effects, but which includes gravity, radiation pressure, photoionization and charge exchange is used for this calculation. The results are then compared with the observations. The resonant scattering of He I 584 A is also treated.
