We reviewed the radiometric ages for Apollo 11 samples that have been determined since the calibration of the lunar cratering chronology, used our new geological map to reinterpret their provenance, and correlated them with the new N (1) values. These are plotted and compared with the lunar ...
阿波罗11号(Apollo 11)是美国国家航空航天局的阿波罗计划中的第五次载人任务,是人类第一次登月任务,三位执行此任务的宇航员分别为指令长尼尔•阿姆斯特朗(Neil Armstrong)、指令舱驾驶员迈克尔•科林斯(Michael Collins)与登月舱驾驶员巴兹•奥尔德林(Buzz Aldrin)。1969年7月20日,阿姆斯特朗与奥尔德林成为了首次踏...

As property of the nation or state, the Apollo 11 lunar samples are now subject to the laws for public gifts as set by that country. In most cases, as in the United States, public gifts cannot be legally transferred to individual ownership without the passage of additional legislation. Since...
Apollo 15— July 26, 1971. Astronauts David Scott, James Irwin and Alfred Worden were part of the mission that carried the lunar roving vehicle, often known as the moon buggy, for the first time to the moon. Their mission emphasized geological work, and the crew was trained to identify di...

In July of 1969, Apollo 11 made a journey to the moon with three brave astronauts aboard, including Neil Armstrong and Buzz Aldrin, who walked on the moon.

The extent to which plants can enhance human life support on other worlds depends on the ability of plants to thrive in extraterrestrial environments using in-situ resources. Using samples from Apollo 11, 12, and 17, we show that the terrestrial plant Ar
Though the near side has large dark patches, the far side has few of these spots. Thespots are called maria, dark areas formed when meteoroids slammed into the moon, erasing previous craters that recorded some of the moon's geological history. But the far side seems to have a more pristi...
