Latest Climate of Mars Stories
Fewer but stronger storms can affect the Earth's climate by changing the distribution of heat and rain in the atmosphere.
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?
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.
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.
ESAâ€™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 ESAâ€™s Science Programme Committee, allows the spacecraft orbiting the Red Planet to continue building on the legacy of its own scientific success.
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 in mid-2002 have appeared on a Martian sand dune. Boulders tumbling down a Martian slope left tracks that weren't there two years ago. Those are just two 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.
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.
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.
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. New understanding about Mars' climate and its polar regions may suggest clues to finding water there.
