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

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...

Newly released images from 340 recent observations of Mars by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter show details of a wide assortment of Martian environments. Strewn boulders and rippled sand lie on the floors of two shadowy, steep-walled pits. Mounds in another region appear to be mud volcanoes, which may have brought fine-grained material to the surface from deep underground. In the Tharsis volcanic region, the intersection...

Scientists now have firm indications that the Martian satellite Phobos formed relatively near its current location via re-accretion of material blasted into Mars' orbit by some catastrophic event. Two independent approaches of compositional analyses of thermal infrared spectra, from ESA's Mars Express and NASA's Mars Global Surveyor missions, yield very similar conclusions. The re-accretion scenario is further strengthened by the measurements of Phobos' high porosity from the Mars Radio...

It spreads, it mutates, it refuses to die. For the seventh year in a row, the Mars Hoax is infecting email boxes around the world. Passed from one reader to another, the message states that on August 27th Mars will approach Earth and swell to the size of a full Moon. "NO ONE ALIVE TODAY WILL EVER SEE THIS AGAIN," the email declares--always in caps. News flash: It's not true. Here are the facts. On August 27, 2010, Mars will be 314 million km from Earth, about as far away as it can get. Mars...

We got some super-creative ideas from people on the NASAJPL Facebook page when we asked this question: "Planning a summer trip? Talk to your friends and family -- if you could design your dream space vacation, where would you go?" As promised, we're posting a small sampling of comments here, but you can read all the comments, or post your own ideas at http://www.facebook.com/NASAJPL. Eoghan Lappin: Moon for breakfast. Mars for lunch. Titan for dinner. Then all the way to Gliese 581d on a trip...

Six hundred recent observations of the Mars landscape from an orbiting telescopic camera include scenes of sinuous gullies, geometrical ridges and steep cliffs. Each of the 600 newly released observations from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter covers an area of several square miles on Mars and reveals details as small as desks. The HiRISE images taken from April 5 to May 6, 2010, are now available on NASA's Planetary Data...

Images from the recent flyby of Phobos, on March 7, 2010, have been released today. The images show Mars' rocky moon in exquisite detail, with a resolution of just 4.4 meters per pixel. They show the proposed landing sites for the forthcoming Phobos-Grunt mission. ESA's Mars Express spacecraft orbits the Red Planet in a highly elliptical, polar orbit that brings it close to Phobos every five months. It is the only spacecraft currently in orbit around Mars whose orbit reaches far...

Technophobia
2013-12-24 11:45:54

Technophobia, from Greek techne, meaning art, skill, or craft, and phobos, meaning fear, is the fear or the dislike of advanced technology or complex devices, particularly computers. Although there are a number of interpretations of technophobia, they appear to become more complex as technology continues to evolve. The term is usually used in the sense of irrational fear, but others contend that their fears are justified. It is related to cyber phobia and it is the opposite of technophilia....

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...
