In its first chemical analysis of soil from Mars' northern plains, NASA's Phoenix lander has turned up no evidence of water, scientists said Monday. (article 1)
Researchers remained confident that the craft is in the right place to uncover veins of ice believed to lie only inches beneath the surface. (article 1)
A soil sample was cooked twice in one of Phoenix's eight ovens over the last few days, according to William Boynton, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. (article 1)
Is the white stuff in the Martian soil ice or salt? That's the question bedeviling scientists in the three weeks since the Phoenix lander began digging into Mars' north pole region to study whether the arctic could be habitable. (article 2)
Shallow trenches excavated by the lander's backhoe-like robotic arm have turned up specks and at times even stripes of mysterious white material mixed in with the clumpy, reddish dirt. (article 2)
Phoenix merged two previously dug trenches over the weekend into a single pit measuring a little over a foot long and 3 inches deep. (article 2)
Two scientific instruments, a microscope and a "bake-and-sniff" analyser, have begun inspecting soil samples delivered by the scoop on the spacecraft's robotic arm. (article 5)
