Nasa's message from Mars: There's water here. I've tasted it

Nasa scientists last night confirmed that there is water on Mars. The space agency's Phoenix lander has identified ice in a soil sample analysed by its on-board laboratory.

Previous orbiting missions had beamed data such as the view of the planet's surface, above. Others indicated there was ice on the red planet - but Phoenix's discovery is the first direct evidence. "I can now say I'm the first mission to Mars to touch and then taste the water," came the message from Phoenix's Twitter feed yesterday.....................WOW!! Why is this not on the front page of every newspaper, magazine, ect. across the globe? i mean, is this history or what?

TUCSON, Ariz. -- 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. "We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA.

"We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month, but this is the first time Martian water has been touched and tasted."

With enticing results so far and the spacecraft in good shape, NASA also announced operational funding for the mission will extend through Sept. 30. The original prime mission of three months ends in late August.

The mission extension adds five weeks to the 90 days of the prime mission. "Phoenix is healthy and the projections for solar power look good, so we want to take full advantage of having this resource in one of the most interesting locations on Mars," said Michael Meyer, chief scientist for the Mars Exploration Program at NASA Headquarters in Washington.

The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday's sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle.
