April 21, 2010 ─ This compilation of video shows some of the first imagery and data sent back from NASA’s Solar Dynamics Observatory (SDO). Most of the imagery comes from SDO’s AIA instrument, and different colors are used to represent different temperatures, a common technique for observing solar features. SDO sees the entire disk of the Sun in extremely high spacial and temporal resolution and this allows scientists to zoom in on notable events like flares, waves, and sunspots.

Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun’s magnetic field and also provide a better understanding of the role the sun plays in Earth’s atmospheric chemistry and climate. Since launch, engineers have been conducting testing and verification of the spacecrafts components. Now fully operational, SDO will provide images with clarity 10 times better than high-definition television and will return more comprehensive science data faster than any other solar observing spacecraft.

美国太阳动态观测台(SDO)卫星系统

美国宇航局(NASA)于2010年2月11日将太阳动态观测台(Solar Dynamics Observatory – SDO)卫星系统成功地发射到太空,在离地球上空22,300英里而与地球同步的轨道上运行。

此太阳动态观测台将仪器对准太阳以观察并搜集太阳风暴的高清晰影像和数据。这些影像和数据可帮助科学家研究太阳风暴或其他太阳活动状况对太空轨道上运行的国际太空站及其他有关系统运转可能产生的影响。

SDO首次发回太阳影像

2010年4月21日美国宇航局在首都华盛顿发布了SDO首次发回的太阳影像和照片。这些新的太阳影像比高清晰度电视的分辨率更清楚10倍,显示了一些以前从未看到过的从太阳黑子向外散发物质的细节。这将对观测太阳磁场,以及研究太阳对地球大气层和气候的影响提供了宝贵的资讯。
