The STARSHINE (Student Tracked Atmospheric Research Satellite Heuristic International Networking Experiment) series of three artificial satellites were student participatory missions sponsored by the United States Naval Research Laboratory (NRL). ==Satellite description== STARSHINE-1 was a spherical satellite that was fitted with almost nine hundred small mirrors polished by students from around the world. Once launched, a network of over 20,000 students from eighteen countries tracked the satellite by observing sunlight glinting off the mirrors and networked their observations via the Internet. The students used these observations to calculate air drag, solar activity, and other orbit related properties of the satellite.〔 (【引用サイトリンク】 title=Satellite Starshine-3 )〕 STARSHINE-2 and -3 had systems added to impart spin to these satellites in an effort to improve the solar-reflected flash rate, as well as a number of laser retroreflectors to introduce the students to satellite laser ranging.〔 (【引用サイトリンク】 International Laser Ranging Service )〕 The satellites were constructed largely from spare flight hardware. 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「Starshine (satellite)」の詳細全文を読む スポンサード リンク
