Several readers have remarked on a new technique developed by scientists at UC Berkeley and University of Massachusetts Amherst that has the promise of achieving storage densities of 10 terabits per square inch. "The method lets microscopic nanoscale elements precisely assemble themselves over large surfaces. ... Xu explained that the molecules in the thin film of block copolymers — two or more chemically dissimilar polymer chains linked together — self-assemble into an extremely precise, equidistant pattern when spread out on a surface... Russell and Xu conceived of the elegantly simple solution of layering the film of block copolymers onto the surface of a commercially available sapphire crystal. When the crystal is cut at an angle... and heated to 1,300 to 1,500 degrees Centigrade... for 24 hours, its surface reorganizes into a highly ordered pattern of sawtooth ridges that can then be used to guide the self-assembly of the block polymers."

DynaSoar writes "Spaceport America received an early and double holiday gift this week: first, the expected (positive) FAA environmental impact report, and second, the hoped-for but not immediately expected 'launch site operator's license.' With this license, and with the previously accomplished creation of a tax district, two of three pieces are in place as required by the New Mexico legislature to receive its funding package. The third, a lease with a space services tenant to use the facility, may come this week also, in the form of a contract with Virgin Galactic. While timing is impossible to predict, the contract is a virtual certainty. The New Mexico Spaceport Authority fully expects it, and so has projected late 2010 for completion of hangar and terminal facilities. Virgin Galactic also seems confident, as they have already screened and submitted their first 100 customers (called the Virgin Galactic Founders) to their contracted medical and training supervisor. They are busy screening their second 100 'spaceflight participants' (NASA and RKA having decided that only those who can tack 'career' on the front of it deserve to be called 'astronauts')."
