U.S.S.R. launched Molniya 117 comsat from Plesetsk into orbit with 39 569-km (24 587,0-mi) apogee, 493-km (306.3-mi) perigee, 711.8-min period, and 64.7° inclination. Tass said satellite would transmit telephone, telegraph, radio, and TV communications to remote areas. (GSFC SSR, 12/31/70; AP, W Post, 12/26/70, A9; SF, 6/71, 213)
JPL had announced availability of certain facilities to qualified investigators from academic community, Science reported. Included were microscopes, spectrometers, wind tunnels, vacuum chamber, hypervelocity laboratory, and image-processing laboratory. Investigators were expected to help defray expenses. Some limited funding would be furnished by JPL. (Science, 12/25/70, 1389)
Experiment to determine if ozone was trapped in solid carbon dioxide polar cap of Mars was described in Science by Univ. of Colorado and York Univ. of Toronto, Canada, scientists. Experiment showed that solid carbon dioxide was effective trap for ozone at temperatures as high as 156 K (-179°F ). "Ultraviolet reflection-absorption spectra of ozone in solid carbon dioxide at 127°K [-231°F] indicate that, the ozone observed over the polar cap of Mars may be trapped in solid carbon dioxide."
