Developed by Rolls-Royce Naval Marine in Walpole, Mass., the new Axial-Flow Waterjet Mk-1 can move nearly half a million gallons of seawater per minute, providing more thrust per unit than current commercial waterjets.

NASA testing vintage engine from Apollo 11 rocket

January 28, 2013 9:46 am | by Jay Reeves, Associated Press | News | Comments

Young engineers who weren't even born when the last Saturn V rocket took off for the moon are testing a vintage engine from the Apollo program. The engine, known to NASA engineers as No. F-6049, was grounded because of a glitch during a test in Mississippi and later sent to the Smithsonian Institution. Now, NASA engineers are using to get ideas on how to develop the next generation of rockets for future missions to the moon and beyond.

Scientists develop new technique for laser micro-machining

August 30, 2012 8:27 am | News | Comments

Many lasers have linear polarization, in which the electric field of the beam is, for example, vertical everywhere. Radial and azimuthal polarizations, however, have a directional change of electric field. By combining a spatial light modulater, a 100 femtosec pulse laser source, and a wave plate, researchers in the U.K. have produced lasers that use these modes to machine materials with portentially greater process efficiency.
