29 Mar 1974 | Journal: | Science, 183 (4131), 1315-1318 | Abstract: | An objective grating spectrometer on Mariner 10 has measured air-glow in the wavelength range 200 to 1700 angstroms. The data reveal the presence of significant concentrations of hydrogen, helium, carbon, and oxygen atoms in the upper atmosphere of Venus. A preliminary analysis of the hydrogen data indicates an exospheric temperature of 400 degrees K. There is evidence for intense air-glow emission at wavelengths longward of 1350 angstroms; the nature of this emission is unclear, but the radiation is spatially extensive and detectable on both day and night sides of the planet. | Source: | PubMed, pmid17791374 doi: 10.1126/science.183.4131.1315 | Services: | Forum | Review | Favorites |
