But as it steadily gets nearer to the Sun the comet's jets are getting more and more active and they're putting on quite a show for the orbiting Rosetta spacecraft! Click the image for a jeterrific hi-res version. The images above were captured by Rosetta's NavCam on Jan. 31 and Feb. 3 from a distance of about 28 km (17 miles). Each is a mosaic of four separate NavCam acquisitions and they have been adjusted and tinted in Photoshop by yours truly to further enhance the jets' visibility. (You can view the original image mosaics and source frames here and here.) These dramatic views are just a hint at what's in store; 67P's activity will only be increasing in the coming weeks and months and, this weekend, Rosetta will be swooping down for an extreme close pass over its surface! This Saturday, Feb. 14, Rosetta will be performing a very close pass of the comet's nucleus, soaring over the Imhotep region at an altitude of only 6 km (3.7 miles) at 12:41 UTC. This will allow the spacecraft to closely image the comet's surface, as well as investigate the behavior of its jets and how they interact with its developing coma. 再过3天,这个礼拜六，2月14日12:41 UTC的时候， 罗塞塔号将要表演很靠近地通过彗星核心(/中心) 在印和阗地区的上面仅6公里处翱翔.这将允许太空船 很近地替这彗星的表面照相,以及调查其喷射(/喷出物)的行为 以及它们如何和它的正在发展中的"昏迷"交互作用。 "The upcoming close flyby will allow unique scientific observations, providing us with high-resolution measurements of the surface over a range of wavelengths and giving us the opportunity to sample - taste or sniff - the very innermost parts of the comet's atmosphere," said Rosetta project scientist Matt Taylor.

(1) 再过3天,这个礼拜六，2月14日12:41 UTC 的时候 你在干嘛? (2) coma怎么翻译呀? (3) 很神奇喔,你有看过那彗星(会移动)的云吗? 有大开眼界吗?
