“惠更斯”号登陆土卫六直播专题！（hot！）

“惠更斯”号将于今天下午5点左右进入土卫六的大气层，进入确认的信号
要在大约70分钟后传回地球，到达地表需要大约2个多小时，也就是说今晚8点
左右就将知道它能否安全着陆。

根本没有任何登陆视频啊（模拟动画除外）。。除了新闻发布会和控制室现场画面以外就没有任何视频了。。

希望能看直播

期待到时能看直播

7月份！可能又是考试期间 :wink:

让我们拭目以待!
希望有爱好者能拍下这一撞击~

呵呵，期待。。。

那就不要错过今年7月4日的撞击彗星的好戏！ 8)

那时在备考,错过好戏了~ :|

顶！！！

:shock: 就是的。

这个应该是在下降过程中拍的吧。。

Titan Descent
January 17, 2005          

This picture is a composite of 30 images from ESA's Huygens probe. They were taken from an altitude varying from 13 kilometers down to 8 kilometers when the probe was descending towards its landing site.

The images have a resolution of about 20 meters per pixel and cover an area extending out to 30 kilometers.

我查看了本版的老贴，还有本版杨睿版主加的另一精华贴，现在就是有四个精华贴了。

这是两个精华的连接：http://www.astronomy.com.cn/bbs/viewtopic.php?t=32544http://www.astronomy.com.cn/bbs/viewtopic.php?t=32689

Audio data collected by the Huygens Atmospheric Structure Instrument (HASI), which includes an acoustic sensor, during Huygens' descent, 14 January 2005.


1. Speeding through Titan's haze
This recording is a laboratory reconstruction of the sounds heard by Huygens' microphones. Several sound samples, taken at different times during the descent, are here combined together and give a realistic reproduction of what a traveller on board Huygens would have heard during one minute of the descent through Titan's atmosphere.

2. Radar echos from Titan's surface
This recording was produced by converting into audible sounds some of the radar echoes received by Huygens during the last few kilometres of its descent onto Titan. As the probe approaches the ground, both the pitch and intensity increase. Scientists will use intensity of the echoes to speculate about the nature of the surface.

不错！第一个象是泰坦上有人骑摩托的声音。。
第2个象是泰坦上的火车声。。
