ESA -- The spectacular features visible today on the surface of the Red Planet indicate the past existence of Martian glaciers, but where did the ice come from? An international team of scientists have produced sophisticated climate simulations suggesting that geologically recent glaciers at low latitudes (that is near the present-day equator) may have formed through atmospheric precipitation of water-ice particles. Moreover, the results of the simulations show for the first time that...

NASA -- NASA's Hubble Space Telescope snapped this picture of Mars on October 28, within a day of its closest approach to Earth on the night of October 29. Hubble astronomers were also excited to have captured a regional dust storm on Mars that has been growing and evolving over the past few weeks. The dust storm, which is nearly in the middle of the planet in this Hubble view is about 930 miles (1500 km) long measured diagonally, which is about the size of the states of Texas, Oklahoma, and...

LOS ANGELES -- Mars is ready for another close-up. For the second time in nearly 60,000 years, the Red Planet will swing unusually close to Earth this weekend, appearing as a yellow twinkle in the night sky. Mars' latest rendezvous will not match its record-breaking approach to Earth in 2003, when it hovered from 35 million miles away. But more skygazers this time around can glimpse the fourth rock from the sun because it will glow above the horizon. "This is the best we're going to see...

ESA -- ESA's Mars Express mission has been extended by one Martian year, or about 23 months, from the beginning of December 2005. The decision, taken on September 19 by ESA's Science Programme Committee, allows the spacecraft orbiting the Red Planet to continue building on the legacy of its own scientific success. Co-ordinated from the beginning with the Mars science and exploration activities of other agencies, Mars Express has revealed an increasingly complex picture of Mars. Since...

LOS ANGELES -- The climate on Mars is showing a warming trend and recent images have shown the first evidence of seismic activity on Earth's neighbor planet, scientists said on Tuesday. New gullies that did not exist three years ago have been pictured on a Mars sand dune -- just another of what scientists say are surprising discoveries found by cameras aboard the 8-year-old Mars Global Surveyor that are changing notions about the climate and formation of Mars. "To see new gullies and...

JPL -- New gullies that did not exist in mid-2002 have appeared on a Martian sand dune. That's just one of the surprising discoveries that have resulted from the extended life of NASA's Mars Global Surveyor, which this month began its ninth year in orbit around Mars. Boulders tumbling down a Martian slope left tracks that weren't there two years ago. New impact craters formed since the 1970s suggest changes to age-estimating models. And for three Mars summers in a row, deposits of frozen...

Earth and Mars will have a breathtaking close encounter in October 2005. Science@NASA -- By the time you finish reading this sentence, you'll be 25 miles closer to the planet Mars. Earth is racing toward Mars at a speed of 23,500 mph, which means the red planet is getting bigger and brighter by the minute. In October, when the two planets are closest together, Mars will outshine everything in the night sky except Venus and the Moon. (You're another 50 miles closer: keep reading!) It's only...

The tiny tornadoes, or dust devils, that scientists have observed from orbit have now been seen close up on the surface by the Spirit rover. The most recent series of images show that these tornadoes can appear suddenly with diameters in the hundreds of feet. Astrobiology Magazine -- A dust devil spins across the surface of Gusev Crater just before noon on Mars. NASA's Spirit rover took the series of images in this 21-frame animation with its navigation camera on the rover's martian day, or...

CORVALLIS, Ore. -- An interdisciplinary team of scientists thinks it has an answer to a long-standing mystery of why the permanent icecap on Mars' South Pole is offset from the pole itself. Simply put, it's colder and stormier in that hemisphere. But that is only part of the equation, scientists say, and new understanding about Mars' climate and its polar regions may suggest clues to finding water in the planet's equatorial zone - where it would be easier to land a spacecraft - and opening...

Bernard Foing, Chief Scientist for the European Space Agency, provides on overview of the most notable discoveries made during the Mars Express mission, Europe's first trip to the Red Planet. In part two of this overview, Foing looks at how these discoveries could help pinpoint the prospects for life on Mars. Astrobiology Magazine -- The European Space Agency's Mars Express spacecraft has been orbiting Mars for over a year. While the high resolution images of the planet's many craters,...
