The mars Phoenix lander is due to touch down on the mars polar ice cap around ~ 19:30 EDT tomorrow. Its first signals are supposed to reach earth at 19:53 EDT - if it doesn't crash and splinter into thousands of million dollar chunks of tax payer bought state of the art debris strewn about the planet's surface (which unfortunately is what happened to its sister craft during the last landing attempt 9 years ago) ... There is a great deal of anticipation to see what awaits it on the surface of the polar ice cap (if it actually makes it in one piece). I'm guessing there will be an abundant assortment of red rocks of various sizes and maybe a thin coat of permafrost covering the soil. but... we won't know with any certainty until 'exactly' 23 hours and 20 minutes from 'now' ..
srsly tho, it should be really kewl.
