Stardust@Home: Search for dust!

Quote

Based on previous measurements of interstellar dust by both the Ulysses and Galileo spacecrafts, Westphal expects to find approximately 45 grains of submicroscopic dust in the collector, a mosaic of tiles of lightweight aerogel forming a disk about 16 inches in diameter - nearly a square foot in area - and half an inch thick. Though those searching for pieces of Wild 2's tail will easily be able to pick out the thousands of cometary dust grains embedded in the front of the detector, finding the 45 or so grains of interstellar dust stuck in the back of the detector won't be so easy.

It also voiced concern that Microsoft would try to seek royalties from companies that sell and support Linux for using the technology, potentially posing a threat to the free software community. Under the terms of the Free Software Foundation's General Public License, Linux cannot be distributed if it contains patented technology that requires royalty payments.


New energy weapons being made.

Directed-energy weapons take the form of lasers, high-powered microwaves, and particle beams. Their adoption for ground, air, sea, and space warfare depends not only on using the electromagnetic spectrum, but also upon favorable political and budgetary wavelengths too.
