Pac-Man Moons of Saturn
“Scientists with NASA’s Cassini mission have spotted two features shaped like the 1980s video game icon “Pac-Man” on moons of Saturn. One was observed on the moon Mimas in 2010 and the latest was observed on the moon Tethys. The pattern appears in thermal data obtained by Cassini’s composite infrared spectrometer, with warmer areas making up the Pac-Man shape.”

This image from the High Resolution Imaging Science Experiment on NASA’s Mars Reconnaissance Orbiter shows “Victoria crater,” an impact crater at Meridiani Planum, near the equator of Mars. The crater is approximately 800 meters (half a mile) in diameter. It has a distinctive scalloped shape to its rim, caused by erosion and downhill movement of crater wall material. Layered sedimentary rocks are exposed along the inner wall of the crater, and boulders that have fallen from the crater wall are visible on the crater floor. The floor of the crater is occupied by a striking field of sand dunes.
A list of all NASA´s current missions
It´s quite easy to get lost in the middle of the data NASA releases to the world on a daily basis. There are more than 50 missions right now under the agency´s supervision, all of them producing a myriad of amazing images and information about many different subjects such as sunspots, Earth´s atmosphere, Saturn´s moons, the birth of stars at distant galaxies and faraway asteroids.
To help us follow all that, NASA has listed all current missions on alphabetical order in a way that clicking on each one of them takes you to a specific page about the mission with all the data you need to understand all those probes, satellites, robots, telescopes and on.
