The Earth's atmosphere is completely opaque to wavelengths shorter than about 3000 A; rockets provided the first means of directly examining this portion of the spectrum. Observations of the solar ultraviolet spectrum were first notably extended beyond the limit detectable at the Earth's surface by means of a spectrograph on V-2 rocket in l946, and one of the earliest triumphs of rocket solar astronomy was the discovery of solar x rays originating in the million-degree corona.
