It's only fitting that the glorious news of water ice on Mars was broke over Twitter this evening, via the Mars Phoenix lander
's own first-person ramblings. Apparently Mars Phoenix was keeping an eye on some white patches it uncovered the other day, only to discover they'd disappeared today. According to the scientist folk over at NASA, that means those white patches must've been ice, which dissipated once uncovered. Now Mars Phoenix still has the considerable task of uncovering more ice and sampling it, but the mission is ahead of schedule and NASA has already identified a hard patch of ground it wants to dig into. Congrats to Mars Phoenix and all the fine folks at NASA, now be sure to watch out for the cave-dwelling little green men!
