Curiosity finally try it out your arm in action. He walked up to the stone in the form of pyramids. Its dimensions are 25 cm in height and 40 in width. Some believe that the stone is of such size and shape of Mars can not simply cobble …
Cobble was named after Jake Mateevika responsible for operations on the surface of the project Mars Science Laboratory, which is the brainchild became Curiosity. The researcher died August 20 at age 64. Mateevik served as previous NASA Mars rovers: Sojourner, Spirit and Opportunity.
To get to the rock, the rover spent six days on the road, going to 22? 37 meters per day.
In Glenelg rover first try to analyze the powder left over from rock drilling. Here, three types of cross country, and one of them is lighter and stronger than the other dotted with craters than the one on which now moves Curiosity. The light area is of special interest because it retains all night daytime heat.
"The closer this light area, the better the visible thin dark bands of unknown origin," — says a project Mars Science Laboratory, John Grottsinger of the California Institute of Technology (USA).
But mast camera Curiosity not only looks down. Rover also photographed the passage of the Martian moons Phobos and Deimos across the solar disk. This is part of a long-term studies of changes in the orbits of satellites. Similar observations were rovers Spirit and Opportunity, have arrived at the Red Planet in 2004.
"The orbit of Phobos is very slowly coming to Mars, and Deimos moves farther and farther" — says Mark Lemmon of the University of Texas A & M. In the calculations of the movement remains uncertain, because the internal structure of Mars is not completely understood. In addition, Phobos causes small changes in the shape of the Red Planet (similarly moon causes the tides on Earth), and these changes, in turn, affect the orbit of the satellite.
Passage of Phobos on the edge of the Sun September 13, 2012. The left photo was taken Curiosity mast camera with a 34-mm lens, right — 100 mm.
Pyramid encountered to the American rovers could be considered a trifle curious, if not for its size. They are, as it turned out, such as: base 40 cm, height 25 cm These data are taken from the page http://earth-chronicles.ru/news/2012-09-20-30920?ls0Fls If you divide 40 cm by 25 cm, will 1.6 — typical of all earthly pyramids aspect ratio of the base and height. For example, for the pyramid of Cheops (the base side of 230 m, the initial height of 146.6 meters), this ratio is 1.57.
Interesting results were obtained by comparing the height of the pyramid of Cheops and the little Martian pyramids. 146.6 / 586.4 = 0.25? 6? ^ 4 = 584.5. Here? = 3.1415 … If you want to know that this result is interesting, I will answer this way: if we assume that in the solar system, nine planets, then Mars — the sixth planet in a row from the edge of the solar system, and the fourth, if you count from the Sun . In other words, the parameters of the Martian pyramids are not accidental.
