Those plucky Mars rovers are still going. Their planned roving time was three months but now more than four years in, NASA is sending Opportunity off on a two-year trek to visit a large crater.
The mission team estimates Opportunity may be able to travel about 100m per day. But even at that pace, the journey could take two years. The rover will stop to study rocks on the way, and in winter months it cannot move because there is not enough sunlight to provide sufficient power for driving.
Water on Mars: confirmed.
Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples.
The lander itself added, on Twitter, "FTW!"
Scientists think that Mars' alkaline soil might be able to grow asparagus.
Although he said further tests would have to be conducted, Mr Kounaves said the soil seemed "very friendly... there is nothing about it that is toxic," he said. "It is the type of soil you would probably have in your back yard -- you know, alkaline. You might be able to grow asparagus in it really well."
About 2 hours ago, the Mars Phoenix rover twittered that it had found evidence of ice on Mars.
Are you ready to celebrate? Well, get ready: We have ICE!!!!! Yes, ICE, *WATER ICE* on Mars! w00t!!! Best day ever!!
The Mars rover said "w00t". Here's the w00t-less press release and the associated images that show the ice sublimating from the surface over the last four days.
Budget cuts at NASA means that one of the two Mars rovers will be shut down, even though it's still doing useful science.
Besides resting Spirit, scientists also likely will have to reduce exploration by Opportunity, which is probing a large crater near the equator. Instead of sending up commands to Opportunity every day to drive or explore a rock, its activities may be limited to every other day, said John Callas, the Mars Exploration Rover project manager at JPL.
The rovers were originally deployed for three-month missions but have operated for more than four years.
Update: NASA decided not to go through with Mars rover budget cuts. (thx, jeff)
High silica content of Martian soil is yet another indicator of past water on Mars. "The fact that we found something this new and different after nearly 1,200 days on Mars makes it even more remarkable."
Using ground penetrating radar, NASA has discovered an ice deposit at Mars' south pole so large that if melted, it would cover the entire planet under 30 feet of water.
Good news, everyone! (spoken in my best Professor Hubert J. Farnsworth from Futurama): one Mars thingie (the Reconnaissance Orbiter) has spotted another Mars thingie, the Pathfinder lander and its Sojourner rover.
Photographs taken by NASA's Mars Global Surveyor suggest that liquid water may still run on Mars. Successive photos of crater gullies show activity in the last 4 years.
Mars Reconnaissance Orbiter recently snapped a picture of the Opportunity rover perched on the rim of Victoria Crater. Opportunity drove more than 5 miles from its landing site to get there. High resolution photo here. Here's where Opportunity is located on Mars.
Middle school students in Indiana and Australia are building edible moon rovers, with the idea that if you're going to ship a car to the moon or Mars, why not have it be edible when you get there?
