TheChang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh mygoodness, did they succeed. This is awesome.
嫦娥2号飞越图塔蒂斯成功地获得图像。我的天啊,他们刚成功。太棒了。
Chang'E2 images of Toutatis
图塔蒂斯的嫦娥2号图像
The closest fly-by was at 08:30:09 UTCon December 13 at an altitude of just 3.2 km and at a relative velocity of10.73 km/s. Quite a few photos were snapped by the CCD camera - including this seriesof photos taken 93 - 240 km away from Toutatis:
距离最近的飞越是在协调世界时十二月十三日08:30:09,距小行星仅有3.2公里,相对速度为10.73公里/秒。利用星载CCD相机拍摄了相当多的照片,包括这一系列距离图塔蒂斯93 - 240公里的照片:
Theimages are much better than I expected them to be. There are also many more ofthem than I expected. I look forward to learning more about how they wereacquired!
这些图像质量比我预料他们做的要好得多。也比我自己所期望的要好得多。我期待着更多地了解他们是如何捕捉到的细节!
These,in combination with the incredible radar images still being acquired fromGoldstone and innumerable optical observations, make Toutatis one of thebest-studied asteroids in the solar system.
结合这些通过金石系统和无数光学观测获得的难以置信的雷达图像,使图塔蒂斯成为太阳系中研究最透彻的小行星。
I'll have more to write about this in thefuture, but I wanted to share the news as soon as I heard it! Today, we needgood news.
我本来想以后再写更多的关于这件事的博文,但是当我听见这个消息时我想马上分享!今天,我们需要好消息。
Many thanks to users yaohua2000 and CosmicPenguin at unmannedspaceflight.com for bringing this to Western attention!
