Comment Re:256mb (Score 1) 543

My Compaq 701z, Athlon 4 1.2 GHz and...256 MB ram, 133 SODIMM. Slow, but I still use it for reading my 40 year collections of X-Men, FF, etc. on DVD (copied to massive 30 GB HD). Foxit runs quickly, screens okay (10x76), but the 7 pound turtle on my chest does get heavy after awhile. At least it has rounded corners.

"Anything and everything probably means we should do collective suicide. "

Interesting, I've ruminated on the likelihood that collective suicide would solve all human miseries: No more human hunger, no more human wars, no more human sadness...but the other animals would still experience the same, in day-to-day life. On a brighter note, there is the possibility of a catastrophic event occuring that only humans would have a chance of stopping or remediating, e.g. an impending asteroid impact. Perhaps our real utility to the animals of Earth would be the role of ultimate protector; that makes me, and my perception of my species feel a little more meaningful. That also feels ironic (and if I couched it as political satire, it would be).

"This is a trillion dollars that are going to be launched into space, never to come back."

This will be a trillion dollars spent down here, on Earth. Of all of the gazillions of space images I have seen, I've never seen bags with $ signs floating around. With luck and perseverance, that will change someday ; )

Are you NUTS? A full 3D course work for biology, MATH (did i say MATH, not LOUD ENOUGH!), geology, etc. would be awesome! You're quite the curmudgeon, and, I suppose, unaware that for some people, a picture is worth a thousand words.

Back in school I took a geology sequence, and one of the aids we used were these stereoscopic maps. 'Course you had to lay the maps flat, position a viewer over the top,& for some of the students it wouldn't work - but when it finally popped it could be quite useful, if one were viewing unvisited terrain. Also, just made the course more interesting, and full-bodied.

Comment Re:NASA, I am disappoint (Score 1) 91

Yeah, over the years I've seen vaporplans for absurdly long rails; however, since the projectile pops out of the thickest parts of the atmosphere in just a few seconds, it seems to me that a sacrificial, ablative shield (like an attritive, onion skin) could possibly sink away the "frying" heat. Who knows, maybe the sheer pressures of the airflow would force the ablated vapors into a boundary layer around the rest of the craft, thus protecting it from friction, and possibly sponsoring a transient, superlaminar flow, reducing friction (I suppose I should have inserted a "Star Trek Jargon Alert" into this post earlier :^) ).

When it comes to money spent, NASA is still the Red Headed Step Child. But from my backyard view of the Multi-verse, humanity currently comprehends 3 curious methods to climb out of our gravity well. Rockets, Elevator, and Anti-Gravity. One works,(but NASA Administrators act like Edith Bunker and won't use Burt Rutan's solution set). The Elevator is still being developed, and looks to be serviceable, eventually, given humanities comprehension of applied Newtonian Mechanics. Anti-Gravity is still the High School Prom Royalty that can not see me for dirt. The first two are mechanically problematic; but the third one, oh the third one, is the one I still have thoughts for.

Don't forget mass-drivers/electromagnetic launchers. I am not a physicist, but it seems to me that EM launchers (of some sort) should be an area of more than passing interest, for both ground- and space-based launches. Oh yeah,$$...Forgot about that.

Submission + - Mercury Turns Out to be a Weird Little World (jhuapl.edu) 1

sighted writes: "The robotic spacecraft MESSENGER, now orbiting the first planet, has found odd features on its surface, including unexplained, blueish 'hollows' that may be actively forming today. The new findings will be published this week in Science. One scientist said, 'The conventional wisdom was that Mercury is just like the Moon. But from its vantage point in orbit, MESSENGER is showing us that Mercury is radically different from the Moon in just about every way we can measure.'"

Submission + - Thermite Reaction Responsible For WTC Collapse? (sintef.no) 6

esocid writes: Christian Simensen, a senior SINTEF scientist believes that heat melted the aluminium of the aircraft hulls, and the core of his theory is that molten aluminium then found its way downwards within the buildings through staircases and gaps in the floor – and that the flowing aluminium underwent a chemical reaction with water from the sprinklers in the floors below. “Both scientific experiments and 250 reported disasters suffered by the aluminium industry have shown that the combination of molten aluminium and water releases enormous explosions,” says Simensen.

"Alcoa Aluminium carried out an experiment under controlled conditions, in which 20 kilos of aluminium smelt were allowed to react with 20 kilos of water, to which some rust was added. The explosion destroyed the entire laboratory and left a crater 30 metres in diameter." Extrapolate that to the 30 tons from the planes, and his theory has some weight to it, no pun intended. The article was published in the trade magazine http://www.aluminiumtoday.com/news/view/world-trade-center-paper-on-tv/aluminium-news/

Submission + - 1/3 of Sun-like stars may have warm Earth analogs (arxiv.org)

The Bad Astronomer writes: "An astronomer studying data from the first 136 days of the Kepler observatory missions has calculated that as many as 34% of all Sun-like stars may have Earth-sized planets orbiting in their habitable zones, where conditions are right for life as we know it. I have some reservations with his numbers, but they do match other studies. There may be 15 billion warm, Earth-sized worlds in our galaxy alone."

NASA To Demonstrate Largest-Ever Solar Sail in Space 91

Zothecula writes "NASA's upcoming Technology Demonstration Missions are intended to 'transform its space communications, deep space navigation and in-space propulsion capabilities.' Three project proposals have been selected for these missions, which should be launching in 2015 and 2016. One of those projects will involve demonstrating a mission-capable solar sail. While NASA has recently tested a solar sail measuring 100 square feet (9.29 square meters), this one will be the largest ever flown, spanning a whopping 409 square feet, or 38 square meters."
