美国国家航空航天局（NASA）的史匹哲太空望远镜（Spitzer Space Telescope）发射10年后，继续用红外眼照亮宇宙黑暗的一面。史匹哲太空望远镜在该机构四大天文观测设备中名列第四。
这台望远镜于2003年8月25日发射，用于探测彗星和小行星，计数恒星，监测行星和星系，并在太空中发现了被称为巴克球（buckyballs）的足球状碳球。史匹哲太空望远镜从地球拖尾轨道上进行科学探测已进入第二个10年，将继续探测远太空和近太空的宇宙。另一项辅助任务是帮助NASA为一个正在筹备的使命观察是否可以找到一些候选的地点，准备对某个近地小行星进行捕捉、迁移和探测。
在华盛顿主管NASA科学事务的副局长约翰•格伦斯菲尔德（John
Grunsfeld）说：“欧巴马总统关于2025年访问某个小行星的目标汇聚了NASA多样化的人才参与一项共同使命。用史匹哲太空望远镜帮助我们了解小行星的特性和确定某个小行星为使命的潜在目标，能够推进科学和探测。”
NASA说，也许史匹哲太空望远镜最令人惊奇的发现来自我们的太阳系之外。史匹哲太空望远镜率先探测到来自我们太阳系以外一颗行星发出的光，这项发现并没有列入使命原来的设计中。
史匹哲太空望远镜将于10月份尝试用红外线观察一颗被命名为2009DB的近地小行星，以更好地确定它的大小。这项研究有助于NASA为该机构实施捕捉和迁移小行星的使命观察候选的地点。

NASA's Spitzer Telescope Celebrates 10 Years in Space

Ten years after its launch, NASA's Spitzer Space Telescope, the fourth of the agency's four Great Observatories, continues to illuminate the dark side of the cosmos with its infrared eyes.
Ten years after its launch, NASA's Spitzer Space Telescope, the fourth of the agency's four Great Observatories, continues to illuminate the dark side of the cosmos with its infrared eyes.
The telescope, launched August 25, 2003, studied comets and asteroids, counted stars, scrutinized planets and galaxies and discovered soccer-ball-shaped carbon spheres in space called buckyballs. Moving into its second decade of scientific scouting from an Earth-trailing orbit, Spitzer continues to explore the cosmos near and far. One additional task is helping NASA observe potential candidates for a developing mission to capture, redirect and explore a near-Earth asteroid.
"President Obama's goal of visiting an asteroid by 2025 combines NASA's diverse talents in a unified endeavor," said John Grunsfeld, NASA's associate administrator for science in Washington. “Using Spitzer to help us characterize asteroids and potential targets for an asteroid mission advances both science and exploration.”
Perhaps Spitzer's most astonishing finds came from beyond our solar system, NASA says. The telescope was the first to detect light coming from a planet outside our solar system, a feat not in the mission's original design.
In October, Spitzer will attempt infrared observations of a small near-Earth asteroid named 2009 DB to better determine its size, a study that will assist NASA in understanding potential candidates for the agency's asteroid capture and redirection mission.
