chinaChina Air Force Engineers propose space-based laser to remove small space junk

No Comments
Researchers from the Information and Navigation College, Air Force Engineering University and the Institute of China Electronic Equipment System Engineering Company performed computational analysis for using a space-based laser to remove space junk. The orbital momentum models of small scale …

lasersDevice creates negative mass and a new way to generate lasers

No Comments
Most objects react in predictable ways when force is applied to them—unless they have “negative mass.” And then they react exactly opposite from what you would expect. Now University of Rochester researchers have succeeded in creating particles with negative mass …

future weaponsUS Navy will test an improved combat laser starting this fall on Amphibious warship Portland
