Scientists did not expect to find much water ice on Mars which is likely the third largest water reservoir on Mars.
NASA’s Cassini spacecraft narrow-angle camera captured five of Saturn’s moons in one image, poised along the planet’s rings on July 29, 2011. Five moons are Janus, Pandora, Enceladus, Mimas and Rhea. Janus (179 kilometers, or 111 miles across) is on the far left. Pandora (81 kilometers, or 50 miles across) orbits between the A ring and the thin F ring near the middle of the image. Brightly reflective Enceladus (504 kilometers, or 313 miles across) appears above the center of the image. Saturn’s second largest moon, Rhea (1,528 kilometers, or 949 miles across), is bisected by the right edge of the image. The smaller moon Mimas (396 kilometers, or 246 miles across) can be seen beyond Rhea also on the right side of the image.
The view was acquired at a distance of approximately 684,000 miles (1.1 million kilometers) from Rhea and 1.1 million miles (1.8 million kilometers) from Enceladus. Image scale is about 4 miles (7 kilometers) per pixel on Rhea and 7 miles (11 kilometers) per pixel on Enceladus.The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.
