카시니 호가 마지막 근접 비행 중에 촬영한 이 사진에서 토성의 달 디오네가 토성과 얼음 고리의 앞쪽에 매달린 모습을 연출하고 있다.

 

디오네의 북쪽이 사진 위쪽이다.

 

이 사진은 카시니 호에 장착된 광각 카메라에 의해 2015년 8월 17일 가시광선으로 촬영된 것이다.

 

사진이 촬영될 당시 카시니 호는 디오네로부터 73,000 킬로미터 거리에 위치해 있었으며 태양 - 디오네 - 카시니 호 순으로 정렬되어 있었다.

사진의 화각은 35도이며 해상도는 픽셀당 4킬로미터다.

PIA17200: Dione with Rings and Shadows

Original Caption Released with Image:

Dione hangs in front of Saturn and its icy rings in this view, captured during Cassini's final close flyby of the icy moon.

North on Dione is up. The image was obtained in visible light with the Cassini spacecraft wide-angle camera on Aug. 17, 2015.

The view was acquired at a distance of approximately 45,000 miles (73,000 kilometers) from Dione and at a sun-Dione-spacecraft, or phase, angle of 35 degrees. Image scale is 3 miles (4 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.
