소행성 베스타의 코넬리아 크레이터

 

 

 

이 합성사진은 NASA의 던(Dawn)우주선이 촬영한 소행성 베스타의 코넬리아 크레이터로서 검은 물질로 만들어진 줄무늬가 선명하게 새겨져 있다.

 

데이터는 던 우주선의 영상분리형 카메라로 촬영된 것으로 던 우주선이 베스타를 고도 선회할 당시, 베스타 상공 680킬로미터 지점에서 촬영한 것이다.

던 우주선에 의해 수집된 사진들은 하나의 사진으로 통합되고, 베스타 표면의 지형모델에 적합하게 덧씌워졌다.

 

사진의 색채는 0.75 마이크론 파장은 붉은색으로, 0.92마이크론 파장은 초록색으로, 그리고 0.98마이크론 파장은 파란색으로 매핑하여 구성되었다.

PIA16631: 3-D View of Dark-Stained Cornelia

 

Original Caption Released with Image:

This composite-color view from NASA's Dawn mission shows Cornelia Crater, streaked with dark materials, on the giant asteroid Vesta. The data were obtained by Dawn's framing camera during the mission's high-altitude mapping orbit, about 420 miles (680 kilometers) above the surface. The images were integrated into a mosaic and wrapped on a topographical model of Vesta's surface.

Scientists colorized the picture by assigning red to the 0.75-micron wavelength, green to the 0.92-micron wavelength and blue to the 0.98-micron wavelength.

 

The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA's Science Mission Directorate, Washington. UCLA is responsible for overall Dawn mission science. The Dawn framing cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research, 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, Braunschweig. The framing camera project is funded by the Max Planck Society, DLR and NASA/JPL.
