...NASA reports that a Martian meteorite may contain the remains of ancient microbes. The evidence is later challenged...
...Rutan don't look like other planes. One of the industry's most innovative and influential designers, Rutan has built a pressurized gondola for a round-the-world balloon attempt, a rigid winglike sail for an America's Cup winner, GM's Ultralight show car and the X-38 NASA crew-return vehicle. He is now testing his most exotic craft yet, the asymmetrical twin-engined Boomerang, designed to prevent instability should one engine fail. And he has set his sights on the $10 million X-PRIZE for the first private spaceship to carry three passengers to sub-orbital altitude...
...drives, nothing about it actually violates the laws of physics. And when in 1989 an IBM team famously spelled the Big Blue logo in xenon atoms, nanotech spread from the basements of feverish acolytes poring over Drexler's seminal book, Engines of Creation (1986), to the research labs of NASA and Xerox PARC. Today nanotech researchers speak not of if but of when. Great leaps forward come from thinking outside the box. Drexler may be remembered as the man who saw how to build a whole...
...wonder the prospect of artificial muscles has NASA, well, pumped. Traditional robots, even in today's miniature sizes, draw heavily from the limited power supplies on a space probe, and their weight translates into higher launch costs. Bar-Cohen says the components required to construct each strip of artificial muscle cost a total of $200, need just four volts of power and weigh only a fraction of an ounce. Says Rob Manning, chief engineer for nasa's Mars Lander missions: "With all of our basketball-sized spacecraft, we're going to need this kind of technology...
...suddenly flickered and died. The blackout was caused not by some routine equipment failure but by a massive storm on the surface of the sun that shorted out an Earth-orbiting communications satellite. Such solar typhoons are not uncommon, and the damage they do can be considerable. Last week NASA announced that it may now be possible to predict the storms and take action to limit their impact...
