From page 2...
... Sounding rocket investigations changed the concept of ionospheric layers to ionospheric regions, showing that what had been regarded as separate layers were generally just ledges on an electron-concentration distribution that increases fairly steadily up to the F£ maximum. Almost all our knowledge of ionospheric chemistry, critically important to an understanding of upper atmospheric processes, stems from rocket soundings.
From page 3...
... If the x rays originate in a hot gas surrounding a neutron star or white dwarf, such emission lines should be present in Scorpius XR-l.
From page 4...
... 4. What energy degradation processes occur associated with the absorption of solar ultraviolet radiation and what is the flux and spectrum of the resulting photoelectrons?
