The utility model provides a model for showing the relative positions and the relative movement among the sun, the earth and the moon, and the model can be used as a teaching aid for courses of astronomy, geography and natural common sense in a primary and a middle schools. The model is...

Part 1: The moon The chemical implications of a “giant impact” model for the origin of the Moon are examined, both for the Moon and for the Earth. The Impactor is taken to be an approximately Mars-sized body. It is argued that the likeliest bulk chemic... HSC O'Neill - 《...
In this paper, the lunar gravity assist (LGA) is investigated under the planar circular restricted three-body problem (PCRTBP) and two-body model. In the PCRTBP, the approximate expression of energy of the LGA in a small region of the Moon is derived. The expression uncovers the mechanism...

WENCHANG, Hainan, March 20 (Xinhua) -- China launched a new relay satellite on Wednesday to provide Earth-Moon communications services, a key step for its future lunar exploration missions such as retrieving samples from the far side of the moon and exploring the lunar south pole region. ...
However, identifying impacts capable of yielding the Earth-Moon system has proved difficult. Previous works found that forming the Moon with an appropriate impact angular momentum required the impact to occur when the Earth was only about half formed, a more restrictive and problematic model than ...
