美国研制的詹姆斯·韦伯太空望远镜(巨大的红外线天文观察仪)将于2014年登台亮相,到时它能探测宇宙中出现的第一代恒星。下面是关于詹姆斯·韦伯太空望远镜的6个有趣的事实。一、太空轨道“折纸”詹姆斯·韦伯太空望远镜(简称JWST)体积巨大无比。它的多层遮阳板的长度达到22米,几乎是哈勃太空望远镜的2倍。为了能够将它装进阿丽亚娜5号重型运载火箭顶部的空气动力载荷舱,詹姆斯·韦伯望远镜的遮阳板和6.5米直径的大反射镜都需要被精心折叠。图1是JWST的模型,显示了它在完全展开下的状态,站在它前面的是位于马里兰州格林贝尔特的美国宇航局戈达德太空飞行中心JWST的全体研究人员。
The James Webb Space Telescope (a huge infrared astronomical observer) developed by the United States will debut in 2014, when it can detect the first generation of stars in the universe. Here are 6 interesting facts about the James Webb Space Telescope. First, the space orbit “Origami ” James Webb Space Telescope (JWST) huge size. Its multi-layered sun visor reaches 22 meters in length, almost twice as long as the Hubble Space Telescope. To be able to fit it into the aerodynamic payload compartment at the top of the Ariane 5 heavy launch vehicle, the sun visor of the James Webb telescope and the large mirror of 6.5 meters in diameter need to be carefully folded.
