MAP OF MOON
HUNDRED FOOT CONTOUR ! REPLICA OF LUNAR ! SURFACE. j WORK AT MT. WILSON. Mount Wilson Observatory. A 100-foot contour level map of the moon is in the malcing here, in charge of Dr. Walter S. Adams, director of Mt. Wilson Observatory. j This involves photographing tihe moon with the 100-ineh telescope, projecting these photographs on a large globe here with cameras of 135-foot focus, and photographing the globe with a-eamera set at suitable positions to produce a standard map. j It will be possible by this method to photograph the globe at one side to show the features now known only as seen at a great slanting angle. \ A True Picture. j Thus will be shown the true picture of the great Apennines range of mountains on the moon which Dr. Adams says are higher than any on the earth, even Mount Everest. ! Another part of the committee's work has been a study of the temperature and light of the moon with the vacuum thermocouple. It was Seth B. Nicholson and Edison Pettit, radiometrists here, who found a change of 346 degrees in temperature on the moon when it passd from sunlight under the earth's shadow. j "It has been found that the temperature of the moon varies from that of boiling water when the sun is overhead to that of liquid air during the lunar night," said Edison Pettit. Pumice Surface. ! "A study of the cooling of the moon during an eclipse shows that the materials of the surface probably are in a porous or powdered condition, and behave physically like pumice, j This conclusion was also arrived at by j a study of the light of the moon. "Whether the lunar craters are of volcanic or meteoric origin or have some other explanation is being studied by the geologists and physicists on.the committee. The general features of the craters as seen under the best conditions with the 100-inch telescope are being compared with mountains on the earth. "In these studies aeroplane photographs of volcanic craters and the meteor crater in Arizona play a part."
