Cassini and Messenger take Earth picture

Today two spacecrafts Cassini and Messenger will arrange a photoshoot

Two NASA spacecrafts, one studying systems of Saturn, another observing Mercury, at the same time will arrive on the taken-away place to photograph Earth, on July 19 and 20. The Cassini spacecraft will take the picture from system between 5:27 and 5:42 evenings of EDT (2:27 and 2:42 PDT or 21:27 and 21:47 UTC) on Friday, July 19. The Cassini spacecraft will be at distance about 900 million kilometers from Earth. NASA urges the population to pose “in style of a wave” in the direction of Saturn during this portrait shooting and then shares the photos on the Internet. Earth photos with the Cassini spacecraft, will be part of more extensive mosaic of systems of Saturn. Processing of images of Earth, as expected, will take some days, and processing of a full mosaic of system of Saturn can take some weeks.

Green Rok from Mercury

According to the Mercury Messenger spacecraft the green rock is from the Mercury

The meteorite scientist Anthony Irving think, that the green rock, which had been found in Marocco last year, may be the first visitor from the innermost planet of our solar system. According to the study the rock, which name is NWA 7325, came from the Mercury. NWA 7325 is a group of 35 meteorite samples. The age of those meteorites is near to 4.56 billion years. The scientist thought that the impact was shot out the NWA 7325 from Mercury to Earth. The scientist Irving is has been studying meteorites for many years, but the NWA 7325 meteorite is unlike any meteorite which had been found before. The Mars meteorites are imbued with Martian atmosphere, which makes them simple in difference to the other rocks. Containing rocks of Vesta, as well as chemically, and the meteorite NWA 7325 different from any of space rock watched the scientists of today. It is the first meteorite from all meteorites, which the scientists observed, which has low intensity. The magnetism passed from a cosmic magnetic field into a rock. So the scientists think that the rock formed as “scum” on the top of the magma. .The geological and chemical composition of the Mercury is familiar to the scientists, and they think, that the surface of Mercury is low in iron. The meteorite is also low in iron. This fact allows the scientists to suggest the version, that the parent body of meteorite is Mercury.

MESSENGER Reveals Colors of Mercury

The subtle yet surprisingly varied colors of Mercury are revealed in the latest images from NASA’s MESSENGER spacecraft (the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) space probe).The 485 kg (1,070 lb) MESSENGER spacecraft was launched aboard a Delta II rocket in August 2004 to study Mercury’s chemical composition, its geology, and its magnetic field. It became the second mission after 1975’s Mariner 10 to reach Mercury successfully when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009.

Tiny Planet Mercury May Be Hiding Water Ice

New evidence from the first probe to orbit Mercury is building support for the idea that the tiny planet may be harboring water ice in some of its most extreme terrain. Certain areas of Mercury’s poles were previously found to be bright in radio waves detected by radar measurements from the Arecibo Observatory in Puerto Rico. Now, the Messenger spacecraft has found that those same bright radar spots appear to be in permanent shadow, according to camera views from the probe’s Mercury Dual Imaging System (MDIS).

Mercury’s Strange Innards

According to new studies the small, sun-scorched planet Mercury has an interior unlike that of any other rocky planet in our solar system and a surprisingly dynamic history. Using observations from NASA’s Messenger spacecraft in orbit around Mercury, researchers have found that the planet’s huge iron core is even larger than they had thought, and it’s likely overlain with a solid shell of iron and sulfur, a layered structure not known to exist on Earth, Venus or Mars.

Earth Messenger Spacecraft Reaches Mercury Orbit

Earth Messenger Spacecraft Reaches Mercury Orbit

After three flybys of Mercury over the last three years, the Messenger spacecraft is poised to settle into the first-ever orbit by a manmade object of the planet closest to the Sun.The goal of the mission is to provide scientists with data on Mercury unparalleled since the Mariner 10 spacecraft passed by three decades ago. And the more we understand about Mercury, NASA says, the more we’ll understand about how the other rocky planets in the solar system–Venus, Mars, and of course, Earth–formed and evolved.
