At Last GLAST

Explanation: Rising through a billowingcloud of smoke, a long time ago from a planet very very close by, this Delta IIrocket left Cape Canaveral Air Force Station's launch pad 17-B at 12:05 pm EDTon June 11, 2008. Snug in the payload section was GLAST, the Gamma-ray LargeArea Space Telescope. GLAST's detector technology was developed for use interrestrial particle accelerators. So from orbit, GLAST can detect gamma-raysfrom extreme environments above the Earth and across the distant Universe,including supermassive black holes at the centers of distant active galaxies,and the sources of powerful gamma-ray bursts. Those formidable cosmicaccelerators achieve energies not attainable in earthbound laboratories. Nowknown as the Fermi Gamma-ray Space Telescope, on the 10 year anniversary of itslaunch, let the Fermi Science Playoffs begin.
费米伽马射线太空望远镜
很久很久以前，三角洲Ⅱ型火箭在一团非常靠近行星的滚滚烟雾云中上升，于美国东部时间（EDT）2008年6月11日下午12点05分离开卡纳维拉尔角空军基地的17-B发射台。而火箭有效载荷部位装载的是GLAST，即伽马射线大面积太空望远镜。GLAST的探测器技术经过开发，应用到地面粒子加速器上。GLAST能够探测到来自地球上空和穿越遥远宇宙极端环境下的伽马射线，包括遥远活跃星系中心的超大质量黑洞和高能伽马射线暴发源。那些强大的宇宙加速器获得了在地球实验室里无法得到的能量。现在它被称为费米伽马射线太空望远镜，在其发射升空10周年之际，费米科学季后赛开始了。
