One answer that is being investigated is mineral storage, particularly hydration of magnesium sulfate salts. If these storehouses protect water from evaporation, a second set of questions arise as to whether their delicate balance between temperature, pressure and humidity could be controlled on any future sample return mission. One priority for future Mars missions is bringing some pristine rocks home during a six months or longer martian journey. Opportunity: On the Edge http://www.astrobio.net/news/article1301.html The Mars Opportunity rover is trying to back its way out of the steep Endurance Crater. Mission planners have judged their first route as too risky, and now look to climb the way they descended months ago. Phobos Up Close http://www.astrobio.net/news/article1300.html The Mars Express high-resolution camera has captured stunning images of the red planet's largest moon, Phobos. Because the moon orbits so close, Mars dominates the sky to a viewer on the surface of Phobos. Leonid Meteors, 2004 http://www.astrobio.net/news/article1299.html The Leonid meteor shower is an annual mid-November chance to view comet dust as it passes across the Earth's orbit. Once every third of a century, the shower becomes a storm. This year, the peak may not offer much of a storm, but the moonless nights of Wednesday and Friday give the best observing opportunities.
