''Jonathan's Space Report'' (JSR) is a newsletter about the space age. It is written by Jonathan McDowell, a Harvard-Smithsonian Center for Astrophysics astrophysicist.〔(【引用サイトリンク】url=http://www.harvardscience.harvard.edu/directory/researchers/jonathan-mcdowell )〕 It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Started in 1989,〔(【引用サイトリンク】url=http://host.planet4589.org/space/jsr/back/news.1 )〕 the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaigned for U.S. compliance with the UN Convention on Registration of Outer Space Objects (1975) and UN Resolution 1721B (1961).〔(【引用サイトリンク】url=http://planet4589.org/space/un/untxt.html )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jonathan's Space Report」の詳細全文を読む スポンサード リンク
