这些图片根据美国国家航空航天局(NASA) “黎明号”(Dawn)太空船环绕巨型小行星灶神星飞行时拍摄的图像制作。
现在公众可在线浏览小行星灶神星的天体图。这些图片根据美国国家航空航天局(NASA) “黎明号”(Dawn)太空船环绕巨型小行星灶神星飞行时拍摄的图像制作。这套天体图以“黎明号”的分幅摄像机在大约210公里的低空拍摄的1万幅图像为蓝本拼接而成。
这些天体图大部分采用地区公路图使用的比例尺,图上每一公分相当于2公里的实际距离。上图是其中的一幅天体图。
德国航空太空中心(Deutsches Zentrum für Luft- und Raumfahrt)的托马斯‧罗志(Thomas Roatsch)说,“创建天体图是一项艰苦的任务,每一张图采用了约400个图像”。9月11日,他在伦敦的2013年欧洲行星科学大会(European Planetary Science Congress)上展示了这些图像。
罗志说:“天体图显示这样一个小型星体的灶神星上的地形是多么极端。仅在南极的投影图上,塞弗里那(Severina)陨石坑已达到18公里的深度;就在一百多公里远的地方,山峰高耸7公里。”

“黎明号“的分幅摄像机由德国凯伦堡-林道(Katlenburg-Lindau)的马克斯‧普朗克太阳系研究所(Max Planck Institute for Solar System Research)主持研制,柏林的德国航空太空中心行星研究所(DLR German Aerospace Center, Institute of Planetary Research)做出了巨大的贡献,同时得到不伦瑞克(Braunschweig)的计算机与通讯网络工程研究所(Institute of Computer and Communication Network Engineering)的合作。马克斯‧普朗克协会(Max Planck Society)、德国航空太空中心和美国国家航空航天局为分幅摄像机项目提供了资金。

Take Virtual Tour of Vesta With New High-Resolution Images

An atlas of the giant asteroid Vesta, created from images taken as NASA’s Dawn mission flew around the object, is now accessible for the public to explore online.
An atlas of the giant asteroid Vesta, created from images taken as NASA’s Dawn mission flew around the object, is now accessible for the public to explore online. The set of maps was created from mosaics of 10,000 images taken by Dawn’s framing cameras at a low altitude of about 210 kilometers.
The maps are mostly at a scale about that of regional road-touring maps, where every centimeter of map is equivalent to 2 kilometers. One of the maps is shown above.
“Creating the atlas has been a painstaking task — each map sheet of this series has used about 400 images,” said Thomas Roatsch of the Deutsches Zentrum für Luft- und Raumfahrt, Germany, who presented the images September 11 at the European Planetary Science Congress 2013 in London.
“The atlas shows how extreme the terrain is on such a small body as Vesta. In the south pole projection alone, the Severina crater contours reach a depth of 18 kilometers; just over a hundred kilometers away the mountain peak towers 7 kilometers,” Roatsch said.

The Dawn framing cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research in Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering in Braunschweig. The framing camera project is funded by the Max Planck Society, DLR and NASA.
