Bueno. I'll make it harder. :-) Unbreathable air (no oxygen!), permanent cloud cover. If I wanted to be a REAL s.o.b. I'd further stipulate no available water. With water available, the manufacture of ascent fuel makes the problem a lot easier. Imagine a ship a lot like the DCX Delta Clipper, a single-stage-to-orbit ice cream cone. Big-ass fuel tank. Fuel it just enough to manage a descent, then electrolyze enough H2O to fill the tanks for the run back to Mama. Keeping the fuel cryogenically cold - that might be tough. A small disposable (yucch) fission nuke - unshielded, behind a soil berm for rad. abatement - will be required to power the fuel splitter and fridge. A solar array capable of keeping up with demand might be too heavy/bulky to take down. My wild musings anyway.

OK Pete, Alex M, and you too, Bawking-Buddy try this real world problem. Asteroid Could Hit Earth in 30 Years 7.07 p.m. ET (008 GMT) March 11, 1998 WASHINGTON - An asteroid will pass close by the Earth in the year 2028, and could conceivably hit us, astronomers warned Wednesday. They said the asteroid, which had not been seen before, would pass as close as 30,000 miles to the Earth. "The chance of an actual collision is small, but one is not entirely out of the question,'' the International Astronomical Union (IAU) said in a statement. The asteroid, a mile in diameter, has been named 1997 XF11. It was discovered by Jim Scotti of the University of Arizona. "It was added to the list of 'potentially hazardous objects' (PHAs) that need to be monitored, lest they are destined to come dangerously close to the earth over the course of the next several centuries. There are currently 108 PHAs,'' the IAU said. Latest observations show it will pass as close as 30,000 miles from the center of the Earth. "The time of encounter would be around 1:30 p.m. Eastern Daylight Time Thursday, October 26, 2028,'' the IAU said. "That evening the object should be visible with the naked eye. In Europe, where it would be dark by that time, the object should be a splendid sight as it moves from northwest to southeast across the sky over a couple of hours.'' The IAU said the computations were still uncertain and it was not clear whether the asteroid might come even closer. It asked amateur astronomers to look for the asteroid. "It should be quite accessible for a while with large telescopes, which in addition to helping establish whether a collision in 2028 is possible, could usefully provide more definite information about the object's size.'' An asteroid that slammed into the Earth 65 million years ago is believed to have kicked up so much dust that it wiped out the dinosaurs. [Editor's Note, dinosaurs weren't completely wiped out. We still have chickens.] foxnews.com Aside from figuring out what the best 30 year Leaps are, what would be a good plan? According to the story, this large 1 mile diameter chunk is going to pass NW to SE across European skies. Now say these guys are off by a few tens of thousands of miles, let's say 30,000 to make it a more meaningful problem. So rather than passing the earth (after dark in Europe), what would you guess, maybe a splashdown in the North Pacific? I wonder if MSFT will have moved by then, state income taxes or no?
