- Meteosat 8 is a weather satellite, also known as MSG 1. The Meteosat series are operated by EUMETSAT under the Meteosat Transition Programme (MTP) and the Meteosat Second Generation (MSG) program. Notable for imaging the first meteor to be predicted to strike the earth, 2008 TC3. Launched 28 Aug 2002 by an Ariane V155, this European Meteorology satellite is in a Geostationary orbit. While Meteosat 8 meteorological instruments are working, solid state power amplifier SSPA-C failed in October 2002. On 22 May 2007, the satellite experienced an unexpected orbit change. This was initially assessed as due to a hit by an unknown object, but that was later assessed not to be credible. The thermal protection was damaged at the same time as the orbit change. Subsequent investigation assessed the Meteosat-8 spinning spacecraft's orbit change due to the mass release of thermal covering whose attachment failed. Meteosat-8 is still operating, and as of April 2013 is providing a backup capability to the Meteosat-10 primary 0-degree Full Earth Scan Service and also a backup to the Meteosat-9 Rapid Scan Service over Europe. In May 2012 Meteosat-8 switched to operating in an Earth Sensor Mode due to a problem with the sun sensor data on board. After modifying the ground image processing system the Rapid Scan Service image quality was restored back to nominal. On 29 June 2016, EUMETSAT approved the proposal of relocating Meteosat-8 to 41.5°E, for the continuation of the Indian Ocean Data Coverage (IODC), replacing Meteosat-7. Meteosat-8 arrived at 41.5°E on 21 September. The distribution of IODC Meteosat-8 data, in parallel to Meteosat-7 data, started on 20 October. On 1 February 2017, Meteosat-8 replaced Meteosat-7 as the official EUMETSAT geostationary satellite for the Indian Ocean. Meteosat-8 is expected to run out of fuel sometime in 2020 and its availability lifetime will end in 2022. (en)

- 米堤歐卫星八號屬於气象卫星 ，又称为MSG-1。 米堤歐衛星系列由EUMETSAT在米堤歐过渡计划（MTP）和第二代米堤歐（MSG）计划下运行，並曾因对第一個预測将撞击地球的隕石2008 TC3，进行拍攝而聞名。 这颗欧洲的气象卫星在发射于2002年8月28日，由亞利安五號G型運載火箭 V155送至地球静止轨道 。 米堤歐衛星八號的固态功率放大器SSPA-C在2002年10月发生故障，但氣象儀器仍正常運作。 2007年5月22日，卫星发生了意外的轨道变化。 最出評估結果为衛星被未知物体击中，但后来被認为評估有誤。 在改变轨道的同时，热保护装置也损坏。 随后的调查認為米堤歐八號轨道变化，是由于覆蓋其上的隔熱物質脫落，造成大量質量脫落所致。 米提歐八號仍在运行，并且自2013年4月起，成为米堤歐衛星十號的0度全球扫描服务、米堤歐衛星九號的欧洲快速扫描服务的備用衛星。 由于搭載的太陽感測器資料出现问题，米堤歐衛星八號于2012年5月切换为在地球感測器模式下运行。 修改地面影像处理系统后，快速扫描服务的影像品質回复到正常水準。 2016年6月29日，EUMETSAT批准将米堤歐衛星八號移至東經41.5°處，以取代米堤歐衛星七號，继续提供印度洋資料覆盖（IODC）。 米堤歐衛星八号于9月21日到达東經41.5°。米堤歐衛星八號與七號的 IODC 資料与于10月20日开始並行發布。 2017年2月1日，米堤歐衛星八號取代米堤歐衛星七號，成为EUMETSAT官方在印度洋的地球静止卫星。 米堤歐八號預計將在2020年的某个时候用完燃料。 (zh)
