Nike-Apache sounding rocket was launched by NASA from TERLS carrying Indian payload to study ionosphere. Rocket and instruments functioned satisfactorily. (SR list)
Apollo 10 and 11 photos of lunar far side had revealed number of probable igneous intrusions, including three probable dikes that crosscut wall and floor of 75-km (46.6-mi) crater, Farouk El-Baz of Bellcomm, Inc., reported in Science. Intrusions were distinguished by their settings, textures, structures, and brightness. Recognition of probable igneous intrusions in lunar highlands supported indications of heterogeneity of lunar materials and plausibility of intrusive igneous activity on moon, in addition to extrusive volcanism.

Results of study of infrared spectra recorded by Mariner VI and VII were reported in Science by Univ. of California at Berkeley chemists Kenneth C. Herr and Dr. George C. Pimentel. Reflections at 4.3 mu suggested presence of solid carbon dioxide in upper atmosphere of Mars. (Science, 1/2/70, 47-9)
MSC announced appointment of Sigurd A. Sjoberg as Director of Flight Operations, replacing Dr. Christopher C. Kraft, Jr., who had been appointed MSC Deputy Director. Sjoberg had been Deputy Director of Flight Operations since 1963. Appointment was effective Dec. 28, 1969. (MSC Release 70-1)
With advent of SST, information on meteorological conditions at higher levels of stratosphere would be needed for routine civil-aviation operations, Frederick G. Finger and Raymond M. McInturff of ESSA's Weather Bureau said in Science. Forecast system would be extended from 12-km (7.5-mi) to 20-km (12.4-mi) altitudes or higher. Forecasting techniques to support SST might be facilitated by exploiting similarities between stratosphere and troposphere weather. Much remained to be done on phenomenon forecasting. Wind effects should be smaller for SST than for subsonic aircraft but wind forecasts might be necessary during winter, when variations were high enough to effect economics of operation. Knowledge of temperature fields and of ozone distribution could prove valuable. Possible solar cosmic radiation hazards would be minimized by ground based forecasting system and onboard detection equipment but sonic boom problem at ground level might be less tractable. Amplification and attenuation of boom by meteorological conditions could be predicted. World Weather Watch of U.N. and ESSA's satellites and spacecraft with ability to depict continuous three-dimensional temperature distribution and wind pressure over entire globe would play major role in providing SST meteorological information, as would SST itself.
