Officials are likely to recommend that the launch of Russia's leading planetary spacecraft, scheduled to take place in less than two months, be put off until 2011. The aim of the Phobos-Grunt mission is to gather soil samples from Phobos, one of Mars' two moons. Details of the suspected postponement were provided on RussianSpace.Web by sources within the Russian space industry, and the future of the mission is expected to be made public within a week. The final decision will depend on the...

British scientists are trying to determine why a Jupiter-style planet orbiting close to its sun has not spiraled into the star and burned up. Wasp-18b is so close to the star Wasp-18 that it completes its orbit in less than an Earth-length day, astrophysicists at Keele University in Staffordshire say. In an article in Nature, they say standard astronomical theories hold the planet should have a lifespan of less than a million years, while Wasp-18b is believed to be a billion years old....

The first joint Chinese-Russian mission to Mars is set to take off in October and reach the red planet in August 2010, an exploration project designer said. A Russian Zenit rocket will launch a Chinese Yinghuo-1 satellite and a Russian Phobos-Grunt unmanned lander, Chen Changya, chief designer of the China-Russia Mars exploration project, told Hong Kong's Wen Wei Po newspaper. Phobos-Grunt is expected to study Mars from orbit, including its atmosphere and dust storms, plasma and radiation,...

European space scientists are getting closer to unravelling the origin of Mars' larger moon, Phobos. Thanks to a series of close encounters by ESA's Mars Express spacecraft, the moon looks almost certain to be a "Ëœrubble pile', rather than a single solid object. However, mysteries remain about where the rubble came from. Unlike Earth, with its single large moon, Mars plays host to two small moons. The larger one is Phobos, an irregularly sized lump of space rock measuring just...

Mars Express closed in on the intriguing Martian moon Phobos at 6:49 CEST on 23 July, flying past at 3 km/s, only 93 km from the moon. The ESA spacecraft's fly-bys of the moon have returned its most detailed full-disc images ever, also in 3-D, using the High Resolution Stereo Camera on board. Phobos is what scientists call a "˜small irregular body'. Measuring 27 km Ö 22 km Ö 19 km, it is one of the least reflective objects in the Solar...

Scientists and engineers are preparing ESA's Mars Express for a pair of close fly-bys of the Martian moon Phobos. Passing within 100 km of the surface, Mars Express will conduct some of the most detailed investigations of the moon to date. The series of fly-bys will take place between July 12th and August 3rd. During the second encounter, the spacecraft will fly within 273 km of the surface. Six days later, Mars Express will close to within just 97 km. Although the Red Planet...

PASADENA, Calif. "“ A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars. The High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took two images of Phobos 10 minutes apart on March 23. Scientists combined the images for a stereo view. "Phobos is of great interest because it may be rich in water ice and carbon-rich materials," said Alfred McEwen, HiRISE principal...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the fast-moving shadow of the moon Phobos as it moved across the Martian surface. The HRSC obtained these unique images during orbit 2345 on November 10, 2005. These observations would not have been possible without the close co-operation between the camera team at the Institute of Planetary Research at DLR and the ESA teams, in particular the mission engineers at ESA's...

MOSCOW (AP) - The Russian Cabinet on Tuesday approved a nine-year government program to expand its space programs, backing the ongoing development of the new Clipper spacecraft as well as building Russia's segment of the international space station. In its statement, the Federal Space Agency did not say how much funding the programs would receive. But it said the government plans include a new project called the Phobos-Grunt, which will be sent to the Martian moon of Phobos to collect soil...

The Planet Mars -- in astronomy, 4th planet from the sun, with an orbit next in order beyond that of the earth. Physical Characteristics Mars has a striking red appearance, and in its most favorable position for viewing, when it is opposite the sun, it is twice as bright as Sirius, the brightest star. Mars has a diameter of 4,200 mi (6,800 km), just over half the diameter of the earth, and its mass is only 11% of the earth's mass. The planet has a very thin atmosphere consisting...

Mars' Moon Deimos -- outermost of two small moons orbiting the planet Mars. Deimos orbits Mars at a distance of about 23,500 km (about 14,100 mi), completing an orbit once every 1.26 Earth days. The moon's orbit is almost circular and is only slightly tilted relative to the Martian equator. Deimos is irregular in shape, measuring about 15 km (about 9 mi) along its longest side and about 11 km (about 6.6 mi) along its shortest side. It is the smallest known moon in the solar system. If...

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
