We don't know what they are. They could be exposures of ice, or they could be exposures of rock. What we have is what you see. So what we're going to do over the next few SORL's (space optics research labs) is go back with the robotic arm and robotic arm camera and get closer in shadow and turn on the blue, green and red LED's (Light Emitting Diodes) so we could get some colour data. So this is really scientific method, this is exploration and discovery, so we either discovered ice or not, but what we want to do is go back and test this.\"\u003cbr/\u003e4.

What we found was an anomaly that looks like we have a short circuit in the ion source. The ion source is a part of the Evolved Gas Analyzer that actually generates the ions that we analyze and this short circuit is intermittent, we are working on some diagnostic packages that we'll send up in the next few days, and we're actually quite optimistic that we have a work around that will allow us to operate the instrument with nearly the full capabilities that we had when it left the ground.\"\u003cbr/\u003e8. Wide of news briefing\u003cbr/\u003eScientists for the Phoenix Mars Lander say they are wrestling with a short circuit on the spacecraft.\u003cbr/\u003eThey said on Friday that the problem was in a device designed to analyze ice and soil dug from the planet's surface. \u003cbr/\u003eThe short circuit was found during testing of the robot.\u003cbr/\u003eThe lander has been going through a series of tests since it arrived on Mars on Sunday.\u003cbr/\u003eThe University of Arizona's William Boyton said the short circuit problem was not considered critical.\u003cbr/\u003eHe said there were at least two solutions  and engineers were working on the best way to fix it.\u003cbr/\u003e\"We're actually quite optimistic that we have a work around that will allow us to operate the instrument with nearly the full capabilities that we had when it left the ground,\" Boyton said.\u003cbr/\u003eScientists also showed photographs of the Martian surface showing what they think might be ice.\u003cbr/\u003eRay Arvidson, Robotic Arm Co-Investigator from Washington University in St. Louis, Missouri, said there were two hypotheses - \"We have rock, we have ice\".\u003cbr/\u003e\"We're really pushing for ice, but we don't know if that's the case yet,\" he said.\u003cbr/\u003e\"The real way to do this is to continue to look at this feature and then get out to the work volume and get the soil and expose whatever ice is underneath, and see if we see a similar tabular shallow structure that we can sample, and bring the material back into the spacecraft to really nail and test the hypothesis of ice versus rock, but this is pretty exciting.\"\u003cbr/\u003ePhoenix was designed to study whether the Martian north pole region could support primitive life forms.\u003cbr/\u003eAn outage occurred on Tuesday in one of two NASA satellites circling Mars when a radio shut off before it could relay commands to the lander to get the eight-foot arm moving, Goldstein said.\u003cbr/\u003ePhoenix has delighted scientists with the first-ever view of the planet's northern arctic region since it descended onto the Martian landscape Sunday.\u003cbr/\u003eIt settled onto relatively flat terrain, largely devoid of rocks, according to NASA.\u003cbr/\u003eThe ground features polygon-shaped patterns likely caused by the expansion and contraction of underground ice, said NASA.\u003cbr/\u003ePhotos taken since the landing show that Phoenix is at the edge of a trough that will make an ideal place for digging, according to scientists.\u003cbr/\u003eThe arm is at the heart of the lander's scientific functions during its three-month experiment.\u003cbr/\u003ePhoenix will dig into the soil with the arm to reach ice believed to be buried inches to a foot deep. It's part of the effort to study whether the site could have supported primitive life.\u003cbr/\u003eAmong the things it will look for is whether the ice melted in Mars' history and whether the soil samples contain traces of organic compounds, one of the building blocks of life.\u003cbr/\u003eA series of photos taken by the lander's camera displayed the surrounding landscape and low hills about
