The Spitzer Space Telescope has two years of retirement havd707

The Spitzer space telescope for two years "retired" Spitzer telescope in the coolant is depleted, infrared spectrometer and multiband imaging photometer stopped working, but the IRAC four cameras in two working in Europe the world’s largest emission of far infrared telescope spectacular moment space Tencent news according to foreign media reports, in order to celebrate beyond the detector the boundaries of space science and technology, the Spitzer Space Telescope research team will be the next phase of the task named beyond". Spitzer project scientist Michael Werner said that the current operation of the situation is beyond the initial set of ability of the Spitzer, and run well. We never thought it would work 13 years after launch, and scientists have discovered many of the things that we never thought would ever be possible to exploit. NASA recently approved Spitzer’s two-year probe mission. In the "beyond" stage, Spitzer met to explore many of the topics in astronomy and cosmology, as well as many planets inside and outside the solar system. In view of Spitzer’s orbit and service time, the "beyond" stage will face a series of Engineering challenges. The Spitzer telescope orbits the earth in the same orbit as the earth, but the distance between the earth and the earth will increase as the speed of the probe is slightly smaller than that of the earth. As Spitzer gets farther and farther, the antenna must be able to communicate with the earth at a high angle to the sun, meaning that some parts of the detector have to withstand higher temperatures. At the same time, Spitzer’s solar panels on the back of the sun, the solar energy is also getting less and less, so the battery is also a huge test. In order to achieve this task, the research team has to update some automatic security system program. The Spitzer telescope, launched in August 25, 2003, has encountered a number of scientific and engineering challenges throughout the course of the mission, and the next phase is likely to continue. The main purpose of the probe in the "beyond" phase includes many of the goals of Spitzer’s original plan, such as galaxies in the early universe, black holes in the central galaxy and exoplanets. Spitzer has many advantages in the study of exoplanets, which has an accurate star positioning system and excellent temperature control. These advantages make it possible to detect extrasolar planets in 2005. Recently, the use of Spitzer’s infrared array camera (IRAC) to explore exoplanets – when a galaxy passing through the star, the star’s light will weaken. IRAC scientists have developed a special way to observe the phenomenon of light attenuation, the use of a single pixel camera to observe. Spitzer’s other exploration of the planet’s technology for gravitational lensing. When a star passes in front of another star, the gravitational pull of the first star shows the effect of the lens, which makes the light from a distant star brighter. Scientists use the micro lensing to find the brightness of the sudden change, which may mean that the galaxy around the stars in front of the operation. Spitzer’s other task is to study the early universe. IRAC can be detected about 12 billion years away相关的主题文章:
