Les Johnson of the NASA Marshall Space Center provides a 37-page presentation on solar sails covering the technical details, past projects and future projects. Near-term work is with various cubesats and solar sails. Near Earth Asteroid Scout The Near Earth …

3dNASA laser wire 3D printing of rocket nozzles is much cheaper and five times faster

0
A new process called Laser Wire Direct Closeout (LWDC) was developed and advanced at NASA to build a less-expensive rocket nozzle in significantly less time. LWDC is a different process than most 3-D printing technologies, which are powder-based and fabricated …

laserAnalog quantum simulation based on laser-trapped circular Rydberg atoms

0
State-of-the-art techniques make it possible to build a spin-chain quantum simulator based on laser-trapped circular Rydberg atoms. This simulator combines the flexibility of atomic lattices and the individual atomic observable read-out typical of ion trap, together with the strong dipole-dipole …

energyPrototype for two beam laser fusion system within a decade if no major hurdles arise

0
Dramatic advances in laser technology are close to making the two-laser approach feasible, and a spate of recent experiments around the world indicate that an ‘avalanche’ fusion reaction could be triggered in the trillionth-of-a-second blast from a petawatt-scale laser pulse, …
