Europa's Ice May Be Miles Thick

serutan writes "Space.com has an article detailing recent measurements of the shell of ice covering what is believed to be an enormously deep ocean on Europa, which could harbor life. The thickness of the ice -- many times the previous estimate -- poses a major obstacle to sending a lander that would burrow down through it to the water. [Seems like if they could make the probe kinda warm it would eventually sink through any amount of ice.]"
