Yes, Raedthinn is just a little bit bigger than Fingers…
http://www.astronautix.com// is, at least for the moment, back up and running. Looks a little slimmer than I recall, but that might simply mean an untrustworthy memory.
Disney/Pixar have “John Carter” coming out in 2012. Taken from the Burroughs novels, this is Pixars first live action flick. There is a very brief glimpse of Tars Tarkas; and of course, the first question to be asked by anyone who has read any of the books is “Why ain’t Dejah Thoris nekkid???”
And who here has *not* played the game “Battleship?” Probably very few. Who here has played “Battleship” and thought, “You know, what the world desperately needs is a major motion picture based on this game, which sets up modern naval ships against alien spacecraft”? Well… probably a slightly smaller fraction.
A famous UFO has turned out to be a hoax. How can life go on? Nothing will ever be the same!
Everyone knows that pit bulls are nothing more than mindless killing machines, a bloodthirsty danger to everyone around them. Take this example, for instance:
Dave Sharpe, of Arlington, Virginia, was suffering with severe post-traumatic stress disorder when he decided to put a pistol in his mouth and commit suicide.
But his pit bull Cheyenne saw him crying with the gun in his mouth and licked his ear, convincing Mr Sharpe he had something to live for.

It’s a dinky little thing, like an ensmallerized Mir. The Tiangong-1(“Heavenly Palace) “target module” is due to be launched later this year, with experiment modules to dock with it later.
A simple on-line payload performance estimator for launch vehicles. Simple, but looks reasonably good:
In 1978, Boeing cranked out a whole lot of information – reports, presentations, artwork, etc. – on the Solar power Satellite concept. The idea was that giant satellites covered on photovoltaic arrays would be built in low Earth orbit, then moved up to geosynchronous, where the power generated would be converted to microwaves, beamed to Earth, captured and converted back into electricity. The idea was grand, it was bold, it was forward thinking and it was doomed. In the early 1980’s the price of oil collapsed from its OPEC Oil Embargo days, and the support for such vastly expensive schemes as SPS vanished.
It was not inevitable, of course. A few minor tweaks to the timeline, and the Arab oil producing states might have kept the cost high: either through simply controlling the price, or by the simple expedient of warfare blasting the crap out of the oil fields. Had oil stayed high, who knows… SPS might’ve become the growth industry of the 1990’s.
Boeing was one of the major companies looking at the SPS concept. Each SPS would be roughly the size of Manhattan, and would produce around ten gigawatts. Hundreds of launches would be required to transport the raw materials to orbital construction bases… and hundreds of workers would be needed in both low Earth orbit and geosynchronous to oversee construction. Boeing mapped out the probable timeline of populations on-orbit. The assumption was that two SPS’s would be built per year; this constant rate of construction is reflected in fairly constant numbers for the construction bases in LEO and GEO; the constantly increasing number of satellites explains the increasing number of maintenance crew. 20 SPS’s would require 1000 crew; 40 would need 1400 and 60 would need 1800.
A whole lot of the assumptions regarding SPS seem sadly laughable from the vantage point of the post-Shuttle years. For example space transport was seen as needing to be incredibly cheap, with blisteringly fast turnaround times and a launch of a heavy lift booster (such as the Space Freighter) every 21 hours or so, for decades on end. Even had those succeeded, the crew numbers are almost certainly far too low. Not only would construction and maintenance have turned out to be a lot harder than hoped… there would be a lot of people not considered in these simple analyses. If you have a construction base that lasts for years… you are going to have families. And people who provide goods and services not only to the crew, but to their families. And the tourists. And the scientists, engineers, bureaucrats and everything else. Without setting out to do so, the SPS concept could easily and necessarily have led to populations in Earth orbit measurable in the thousands to tens of thousands.
Had work begun on SPS in earnest in 1980, the first flights might have started in 1990 or so. By which point we’d be two decades into the project. Assuming they kept on schedule (ha!), we’d now have at least 40 SPS satellites, each providing 2.5 gigawatts of net electrical power. That’s 100 gigawatts; over a year, 876,000 gigawatt-hours. Energy usage in the US today is about 29 petawatt-hours = 29,000,000 gigawatt-hours. Thus… a whopping 3% of todays American energy needs could be filled by twenty years worth of solar power satellite construction. Meh. One could always assume that twenty years of technological advancement might’ve improved the efficiency of the solar cells and the transmission systems, bumping up the net power produced by a satellite; still, it’d take a whole lot of satellites to make a real dent in Americas energy needs.
Just how different are they? Consider:
Some interesting stuff showing how the Nazis themselves saw little difference between Hitlerism and Leninism.
At the ten minute mark, watch George Bernard Shaw explain that those who do not produce more than they consume should be *killed.* Not “not put on welfare,” not “kicked to the curb,” but exterminated. Shaw wasn’t a Nazi, but he was a socialist. Shaw *may* have been being sarcastic or telling a particularly bad form of joke, but the fact remains that when commies come to power, they do seem to enjoy killing lots and lots of people.
