It is a temporary replacement for the ICESat satellite until ICESat-2 launch in 2017. ==Equipment== Since 2003 NASA has used a satellite, ICESat (Ice, Cloud, and land Elevation Satellite), for observing polar ice. ICESat was retired in February 2010 due to a technical malfunction, leaving NASA without a satellite dedicated to ice observance. A new satellite is not expected to be launched until 2016. NASA therefore introduced the IceBridge program which utilizes an aircraft to make similar measurements. IceBridge flights began in October 2009 using a DC-8. Beginning in 2010, the DC-8 was joined by a P-3 Orion and other aircraft such as a King Air B-200, Gulfstream V and Guardian Falcon.〔(【引用サイトリンク】title=IceBridge Aircraft & Instruments )〕 There are tradeoffs to using an aircraft instead of a satellite. One drawback is that a satellite can observe a far wider area. Also, satellites take measurements full-time, while IceBridge aircraft measurements are limited to annual campaigns that are several weeks long. Aircraft, however, have the advantages of being able to carry more instruments and target and focus on scientifically interesting areas instead of just flying a fixed path. Also, certain instruments such as ice-penetrating radar only work from the lower altitudes afforded by aircraft like the P-3 Orion and DC-8.〔〔 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「Operation IceBridge」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
