Landsat 8 is an American Earth observation satellite launched on February 11, 2013. It is the eighth satellite in the Landsat program; the seventh to reach orbit successfully. Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USGS). NASA Goddard Space Flight Center provided development, mission systems engineering, and acquisition of the launch vehicle while the USGS provided for development of the ground systems and will conduct on-going mission operations. The satellite was built by Orbital Sciences Corporation, who served as prime contractor for the mission.〔(【引用サイトリンク】title=Fact Sheet - LDCM Earth Image Collection Satellite )〕 The spacecraft's instruments were constructed by Ball Aerospace and NASA's Goddard Space Flight Center,〔(【引用サイトリンク】title=LDCM Spacecraft )〕 and its launch was contracted to United Launch Alliance. During the first 108 days in orbit, LDCM underwent checkout and verification by NASA and on 30 May 2013 operations were transferred from NASA to the USGS when LDCM was officially renamed to Landsat 8.〔(【引用サイトリンク】title=Landsat 8 Satellite Begins Watch )〕 == Launch == The satellite was launched aboard an Atlas V 401 carrier rocket with an Extended Payload Fairing. The launch took place at 18:02 UTC (10:02 PST) on 11 February 2013, from Space Launch Complex 3E at Vandenberg Air Force Base. Seventy eight minutes and thirty seconds later, the spacecraft separated from the upper stage of its carrier rocket, successfully completing the launch.〔(【引用サイトリンク】title=Atlas Launch Report - Mission Status Center )〕 Landsat 8 joins Landsat 7 on-orbit, providing increased coverage of the Earth's surface. 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「Landsat 8」の詳細全文を読む スポンサード リンク
