Radio Observations of Mars

Abstract

THERMAL radio emission from Mars was first detected by Mayer, McCullough and Sloanaker during the favourable opposition of 1956 at 3.15 cm (ref. 1). Further observations at this wave-length made near the opposition of 1958 with improved accuracy gave an equivalent black-body temperature of 211° ± 20° K (ref. 2). In 1962 Drake measured a value of 177° ± 17° K for the temperature at 10 cm (ref. 3). These temperatures are somewhat lower than the infra-red temperatures of 230° to 260° K determined by several workers4–6.
