Deimos Orbital Model Improved
2012-09-26 10:27:22

April Flowers for redOrbit.com - Your Universe Online 135 years ago, a scientist named Asaph Hall discovered Phobos and Deimos, two small moons orbiting Mars. Since then, the moons have been photographed innumerable times from Earth and from spacecraft, including recent measurements by the Mars Exploration Rovers panoramic cameras and the Mars Reconnaissance Orbiter. The orbit of Phobos, the inner moon, has been calculated to an accuracy of less than 1 kilometer. But, despite this...

Lee Rannals for redOrbit.com - Your Universe Online Curiosity got to witness an Earth-like experience on the Martian surface last week, by watching the moon Phobos create an eclipse on Mars. NASA unveiled new images on Wednesday, as well as an update to Curiosity's whereabouts. On September 13, Curiosity witnessed a Martian moon transit that involved the moon Phobos coming between the Red Planet and the Sun. The new rover snapped images of the event using its Mast Camera, which is...

Russia Announces Manned Moon Mission By 2030
2012-04-30 10:52:02

Roscosmos, the Russian space agency, announced this past weekend that it is planning to send a manned mission to the moon by 2030, reports RIA Novosti. The space agency said that it will start off resuming its lunar activities by 2015 by using an unmanned space ship. Roscosmos head Vladimir Popovkin voiced back in January that the agency desired to set up a manned moon research base with European and U.S. partners. Popovkin said that there were plans to either set up a moon base, or...

Working Models For Phobos Gravitational Fields Updated
2012-03-05 05:05:42

Phobos is the larger and closer of the two natural satellites of Mars. Despite decades of Martian exploration, we still know very little about Phobos. Many fundamental properties of this small potato-shaped body stay vague, for example, its gravitational field. SHI Xian and coauthors from Shanghai Astronomical Observatory and Technical University Berlin recently updated working models for the gravitational field of Phobos. Their work, entitled "Working models for the gravitational field of...

Russia Now Blames Cosmic Radiation For Failed Mars Mission
2012-02-01 05:52:10

Russian space agency Roscosmos announced on Tuesday the initial results of an investigation into its failed Mars mission, blaming cosmic radiation for a computer glitch that ultimately doomed the Phobos-Grunt spacecraft, Moscow's first deep space mission in twenty years. "The most likely reason in the commission's opinion is the local influence of heavy charged particles from outer space on the onboard computer system," the RIA Novosti news agency quoted Roscosmos chief Vladimir Popovkin...

Russia Boosts Space Program Through 2016
2012-01-25 13:49:59

Russian media sources have reported that the Kremlin has agreed to fully finance numerous space research programs for one of the country´s top aerospace engineering companies through 2016. According to Viktor Khartov, chief of the Research and Production division of the state-owned aeronautics firm Lavochkin, the Russian government has authorized full funding for two planned Moon missions, one trip to Venus and a handful of new scientific research satellites that will be used for...

Russia Blaming U.S. Radar For Phobos-Grunt Failure
2012-01-17 12:35:59

Russia said on Tuesday that radiation from U.S. radar is most likely to blame for causing the Phobos-Grunt probe to fail its mission to Mars. The RIA-Novosti news agency said that Yury Koptev, head of the scientific committee of state technology company Russian Technology, confirmed the theory. "To test (the theory), an equipment block similar to the one on Phobos-Grunt will be exposed to radiation from the possible unintentional exposure to American radars," Koptev, a former head of...

Actual Location Of Crashed Russian Probe Still Unknown
2012-01-16 15:00:42

Russian officials said on Monday that they still could not say for certain where the Phobos-Grunt space probe landed upon its return to Earth, despite reports over the weekend that it had landed in the Pacific Ocean. According to MSNBC reports Sunday, the satellite's re-entry was believed to have occurred at approximately 12:45 Eastern time, and the debris zone was believed to be 775 miles — or 1,250 kilometers — west of Wellington Island in the South Pacific. That...

Phobos-Grunt Expected To Return To Earth This Weekend
2012-01-14 04:38:45

The Russian probe that has been stranded in Earth's orbit since its November launch is expected to return to Earth within the next few days, according to various media reports Friday. Brian Vastag of the Washington Post said that the Phobos-Grunt spacecraft, which was to travel to Mars to study one of that planet's two moons, "will plunge to its doom this weekend, likely on Sunday." Ned Potter of ABC News wrote that the probe would "most likely" fall back to Earth on Sunday or Monday....

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...
