Mars with ice, shaken, not stirred

10-25-2007 · EurekAlert!

Mars, like Earth, is a climate-fickle water planet. The main difference is that water on the frigid red planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice. That's the global picture literally and figuratively coming into much sharper focus as various Mars-orbiting cameras send back tomes of unprecedented super high-resolution imagery of ever-vaster tracts of the planet's surface.

  1. EuroNews looks at life on Mars!
    02-08-2008 · European Space Agency (ESA)
    Is there life on Mars? ESA's Mars Express satellite, launched in 2003, has been scanning and mapping the surface of our rocky neighbour, and it has found that there are both substantial deposits of water ice below the Martian crust and traces of methane in the Martian atmosphere. The next step is ExoMars, due for launch in 2013, which will place a lander on the surface of the red planet with the express aim of searching for past or present signs of life. EuroNews talked to the scientists at the cutting edge of this research.

  2. U-M scientist says Mars winds could pose challenges
    07-27-2007 · EurekAlert!
    Martian winds probably won't cause serious problems for NASA's upcoming Phoenix Mars Lander mission, but could complicate efforts to collect soil and ice at the landing site, according to University of Michigan atmospheric scientist Nilton Renno.

  3. 'Extreme analytical chemistry' will help unravel Mars' mysteries
    08-02-2007 · EurekAlert!
    Sam Kounaves is spearheading the chemical analysis of Martian soil and ice for the NASA Phoenix Mars mission that will launch in early August and land on Mars next May. Kounaves examines big questions of planetary science by applying "extreme analytical chemistry" to harsh environments like Death Valley, Antarctica -- and now Mars. He says Mars holds vital clues to climate change on Earth.

  6. Looking for life on Jupiter's icy moon Europa
    02-23-2007 · EurekAlert!
    If life exists on other planets, it almost certainly will be found where there's water. While many scientists pin their hopes on Mars, UC Berkeley paleobiologist Jere Lipps yearns to probe Jupiter's moon Europa, because its jumbled ice cover reminds him of the Antarctic ice sheets that are home to abundant life on Earth. Lipps and three other scientists discussed the possibilities at the recent AAAS meeting.

  8. Arizona State University scientist finds Martian ice is patchy and variable
    05-02-2007 · EurekAlert!
    For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.

  9. The origin of perennial water-ice at the South Pole of Mars
    07-13-2007 · European Space Agency (ESA)
    Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole.

  10. Observations give precise estimate of Mars ice
    09-21-2007 · Massachusetts Institute of Technology (MIT)
    An MIT-led team of scientists has found that the southern pole of Mars contains the largest deposit of frozen water in the inner solar system, outside of Earth. The work shows that water, not carbon dioxide, is the predominant frozen liquid in that area.
