NASA Spacecraft Confirms Martian Water, Mission Extended

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.

"Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We're excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected from all the Mars simulation testing we've done. That has presented challenges for delivering samples, but we're finding ways to work with it and we're gathering lots of information to help us understand this soil."

Since landing on May 25, Phoenix has been studying soil with a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. Besides confirming the 2002 finding from orbit of water ice near the surface and deciphering the newly observed stickiness, the science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present.

The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead.

"It's a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.

A full-circle, color panorama of Phoenix's surroundings also has been completed by the spacecraft.

"The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of Texas A&M University, lead scientist for Phoenix's Surface Stereo Imager camera. "They help us plan measurements we're making within reach of the robotic arm and interpret those measurements on a wider scale."

The Phoenix mission is led by Smith at the University of Arizona with project management at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and development partnership at Lockheed Martin in Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus in Denmark; the Max Planck Institute in Germany; and the Finnish Meteorological Institute.

Sweet, now all they need to find is some living organisim.

Things are looking good for possible future terraforming.

I think this is the most difficoult bit to do, and to establish that it is not contamination from bacteria etc brought there by the rover it self. I still doubt the life signs found in mereorites that have been on earth for a few hundred years. Even if the isotope ratios of the organisms is not earth like, it is just evedence that the organsim have eaten the minirals on the meteorite ;)

We are allowed to dream :D Now to get rid of all the dust on Mars.

what is terraforming?:confused:

okay i'll try explain. basically it would involve sending robots to polute it with greenhouse gasses to create an atmosphere and a blanket effect in attempt to warm things up to melt the ice enough for plants to grow there and slowly build up enough oxygen for mamils and maybe reptiles to surive.

Yeah and this documentary that I watched a while ago said that the process of heating up the planet and getting the air oxygenised would take 10 000 years. Pity we'll never get to experience it. :(

Ok, so the warming process should take a few decades, but to get Mars's atmosphere so that humans can breath on it will take tens of thousands of years(according to "The Mars Underground")
