Moondivinercold spotsimpact cratersregolithMapping of lunar nighttime surface temperatures has revealed anomalously low nighttime temperatures around recently formed impact craters on the Moon. The thermophysically distinct "cold spots" provide a way of identifying the most recently formed impact craters. ...
Impact cratering on the Moon and the derived size-frequency distribution functions of lunar impact craters are used to determine the ages of unsampled planetary surfaces across the Solar System. Radiometric dating of lunar samples provides an absolute age baseline, however, crater-chronology functions ...
“Although we have a pretty good idea there’s ice inside the coldest and darkest craters on the Moon, previous measurements have been a little bit ambiguous,” said Barbara Cohen, principal investigator of the mission at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Scientificall...
(PSRs) are hoped to harbor water ice, will need 2 launches / remote docking in orbit; Chandrayaan 5, ISRO-JAXA collaboration now called LUPEX flies NET 2028-2029, 6,000-kg lander taking rover precisely to 89.45° S / 222.85° E on ridge between Shackleton / de Gerlache craters near ...
In the next five years, China is planning to bring two more probes onto the moon to explore its polar regions, a place believed to contain water ice, especially in the deep, permanent shadows of some mountains and craters. China will launch the Chang'e-6 lunar probe to collect and bring...
C. Öpik’s work suggested that the craters on the Moon may have had several causes D. Öpik’s work proved that only high-velocity impacts at 90° could have caused lunar craters. 5. According to paragraph 3, which of the following best describes the impact of a meteor striking at ...
In 1962 Shoemaker made a case for the impact formation of Copernicus Crater, one of the most prominent craters on the near side of the Moon.Before the decade was out, most scientists had come to accept that lunar craters were formed by impact rather than volcanism. ...
