Stereo Phobos

Explanation: Get out your red/blue glasses and float next to Phobos, grooved moon of Mars! Captured in 2004 by the High Resolution Stereo Camera on board ESA’s Mars Express spacecraft, the image data was recorded at a distance of about 200 kilometers from the martian moon. This tantalizing stereo anaglyph view shows the Mars-facing side of Phobos. It highlights the asteroid-like moon’s cratered and grooved surface. Up to hundreds of meters wide, the mysterious grooves may be related to the impact that created Stickney crater, the large crater at the left. Stickney crater is about 10 kilometers across, while Phobos itself is only around 27 kilometers across at its widest point.

说明: 取出你的红/蓝眼镜,一起漂浮在火星满布沟渠的火卫一之旁。这幅由火星特快车号高解析立体相机所拍摄的2004年影像,取像时与火卫一的距离大约是200公里。这幅迷人的立体影像,呈现向着火星那面的火卫一。影像突显这颗酷似小行星的卫星上,满布陨石坑和沟渠的表面。这些最宽可达数百公尺的神秘沟渠,成因可能和造就史迪克尼坑的撞击有关。史迪克尼坑宽约10公里,而火卫一最宽处却只有27公里左右。
