Summary Curiosity outfitted its high-resolution camera with protective filters and took pictures of the sun.
NASAs Mars rover Curiosity, dispatched to determine if the planet most like Earth in the solar system could have supported microbial life, has taken on a second job - moonlighting as an astronomer.Last week, Curiosity outfitted its high-resolution camera with protective filters and took pictures of the sun as Phobos, one of Mars two small moons, sailed by.It was a tricky shoot. Phobos and its sister moon Deimos are closer to Mars than our moon is to Earth, so they shoot across the sky relatively quickly. Phobos takes less than eight hours to circle Mars. Deimos takes about 30 hours to make the trip.Last Thursday (September 13), the moons started to cross paths.The rover took more than 600 images with its left and right cameras, about 100 of which captured some part of the eclipse. Not all the pictures have been radioed back to Earth.Curiosity has a partner in the project. From the other side of the planet, the rover Opportunity was expected to try to shoot the eclipse on Wednesday.Aside from pretty pictures, the images should help scientists learn more about Mars internal structure. Like Earths moon, Mars moons have some gravitational pull that slightly change the planets shape.In 10 million to 15 million years, Phobos is expected to be so close to Mars that it will be torn apart by the planets gravity.The moons passages by the sun, captured by NASAs rovers, help scientists nail down their orbits and determine how fast they are changing. That information in turn is used to assess how much Mars is deformed as the moons go by.The next Martian eclipses will take place in about 11 months. By then, Curiosity should be in a better vantage point.
