今天,喷气推进实验室JPL的网站正在快速发布卡西尼探测器昨天和前天拍摄的土卫二的图片.土卫二(Enceladus)已被探测到有冰火山的存在,被认为在冰层下,有大量的液态水,因而有一定可能存在微生物.更多信息请访问: http://saturn.jpl.nasa.gov 由于没有时间写更多的文字材料,请大家参阅图片为主,所有图片均为未校准过的RAW IMAGE.土卫二表面比较年轻,有大量的沟壑,希望有兴趣的地质研究者尝试进行影像解译.国内学者在尝试利用行星际无人探测器研究太阳系天体地质方面已经有先例,如韩同林等人《火星地貌与地质》一书就是很好的作品。 图1，图片说明： W00060951.jpg was taken on November 02, 2009 and received on Earth November 02, 2009. The camera was pointing toward ENCELADUS at approximately 9,988 kilometers away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2010. 图2：图片说明： N00145324.jpg was taken on November 02, 2009 and received on Earth November 02, 2009. The camera was pointing toward ENCELADUS at approximately 14,188 kilometers away, and the image was taken using the CL1 and IR3 filters. This image has not been validated or calibrated.
