摘要:
For two weeks last December, we had the opportunity and privilege to visit the mapping, charting, and geodetic (MC&G) facilities in the People's Republic of China (PRC) as guests of the National Bureau of Surveying and Mapping (NBSM). There are two principal departments in the PRC that deal with the field of mapping: namely, the National Bureau of Surveying and Mapping, a civilian organization; and the Military Bureau of Surveying and Mapping (MBSM), which is the military MC&G counterpart. Both organizations have worked the national mapping program in China during the last 20 to 30 years.Our tour was spent mostly with the NBSM and included visits with its provincial bureau in Guangzhou (Canton), the Wuhan College, the Research Institute in Beijing (Peking), and the Publishing House in Beijing. It also included a meeting with the NBSM headquarters' staff, also in Beijing; near the end of the tour we spent a full day with the Military Bureau.

摘要:
Kinked rings, a hamburger‐shaped satellite, and swirling equatorial,storms on Saturn added up to a Voyager 2 encounter dubbed ‘a 200% success’ by project scientist Edward C. Stone. Despite problems with the spacecraft's scan platform, the mission sent scientists scurrying back to their laboratories to sort through a plethora of data, including more than 17,000 photographs, which streamed back to earth from more than a billion miles away. Some early findings, such as the absence of tiny moonlets embedded in the rings, perplexed Voyager scientists; other discoveries, such as detailed information provided by the photopolarimeter on the ring structure, incited wild celebration. Detailed analysis will take months and, for some experiments, years. Here are some preliminary results from Voyager 2's Saturn enco
