Mars Moon Probe To Return To Earth Next Week
2012-01-02 04:48:21

The Russian probe that was to explore Mars' moon Phobos before becoming stranded in orbit is expected to fall back to Earth sometime next week, various media outlets are reporting. Early last week, European Space Agency (ESA) space debris chief Heiner Klinkrad told Space.com columnist Leonard David that current re-entry forecasts predict that the Phobos-Grunt satellite, which was launched on November 9, could plummet through Earth's atmosphere on January 14 or 15, plus or minus five day....

Russian Probe To Crash Back To Earth Next Month
2011-12-20 05:35:54

Russia´s space agency said on Friday that its Phobos-Grunt spacecraft, which was originally bound for a moon of Mars but has been stranded in orbit since November, will instead fall back to Earth next month. Most of the toxic fuel and radioactive material onboard the unmanned spacecraft are expected to burn up on re-entry, but 20-30 fragments of the probe will survive to the surface, the space agency (Roscosmos) warned. Current estimates for the timing of the fall are between...

Russia Blames HAARP Transmitter For Phobos-Grunt Failure
2011-12-15 12:32:37

After abandoning efforts to save its Martian moon probe, Phobos-Grunt, that has been stranded in Earth´s orbit since early November, Russia is now focusing on where the blame lies for the expensive mishap. The accused: Alaska´s High-frequency Active Auroral Research Program (HAARP) transmitter. Phobos-Grunt, now considered a 7.5 ton heap of space debris, is expected to plunge back to Earth around January 9, two months after it became stranded, according to Russian space agency,...

ESA Attempting Again To Contact Russia’s Failed Mars Probe
2011-12-13 12:15:02

After previously announcing that efforts to contact Russia´s stranded Phobos-Grunt Mars probe had been abandoned, the European Space Agency (ESA) is now saying that two more attempts will be tried in hopes of allowing a controlled reentry. The attempts will be performed by ESA´s 15-meter antenna in Maspalomas, a station in the  Canary Islands´ Gran Canaria. “We will make two more attempts on Tuesday on a request from the Russian side,” Rene Pichel said....

European Space Agency (ESA) efforts to contact the stranded Phobos-Grunt probe have been abandoned, the organization has announced. The probe, which was scheduled to head to the largest of Mars' two moons on a roughly 2.5 year mission, was stranded in Earth's orbit shortly after its November 9 launch. Last week, both the ESA and the Russian Federal Space Agency (Roscosmos) were able to briefly re-establish contact with Phobos-Grunt, but further attempts to send commands to the probe have...

Russia Makes Contact With Phobos-Grunt Probe
2011-11-25 06:23:05

Officials with the Russian Federal Space Agency (Roscosmos) said on Thursday that they had successfully made contact with the stranded Phobos-Grunt probe, one day after the European Space Agency (ESA) reported having received a signal from the craft. According to AFP reports, the Interfax news agency quoted Roscosmos spokesman Alexei Kuznetsov as stating that the agency had received "a signal" and "some telemetry data" from the probe on Thursday afternoon, and that "specialists" at the...

Mars Phobos-Grunt Probe Has Finally Responded To Signals
2011-11-23 08:00:32

Russia´s Phobos-Grunt space probe, lost in Earth´s orbit for the past two weeks, has finally responded to a signal from space officials working for the European Space Agency (ESA). ESA said on its website today that its tracking station in Perth, Australia had received a signal from the probe at 2025 GMT on Tuesday. ESA is now working with Russian space agency Roscosmos to try to maintain communications with Phobos-Grunt. “ESA teams are working closely with engineers in...

Deadline Passes, Still No Communication with Russian Mars Probe
2011-11-12 11:33:05

After another failed attempt to make contact with the Phobos-Grunt probe, reports have surfaced that the Russian space agency (Roscosmos) will abandon the $160 million satellite to its fate, meaning that the spacecraft and the 12 tons of toxic fuel it carries could soon come plummeting back to Earth. Early Saturday morning, an unidentified source told RIA Novosti, "Attempts to make contact were made overnight and this morning by Russian specialists from the European Space Agency. This was...

Earlier this month, ESA's Mars Express performed a special maneuver to observe an unusual alignment of Jupiter and the martian moon Phobos. The impressive images have now been processed into a movie of this rare event. At the moment when Mars Express, Phobos, and Jupiter aligned on 1 June 2011, there was a distance of 11 389 km between the spacecraft and Phobos, and a further 529 million km to Jupiter. The High Resolution Stereo Camera on Mars Express was kept fixed on Jupiter for the...

A new Mars movie clip gives us a rover's-eye view of a bluish Martian sunset, while another clip shows the silhouette of the moon Phobos passing in front of the sun. America's Mars Exploration Rover Opportunity, carefully guided by researchers with an artistic sense, has recorded images used in the simulated movies. These holiday treats from the rover's panoramic camera, or Pancam, offer travel fans a view akin to standing on Mars and watching the sky. "These visualizations of an alien sunset...

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...
