NASA seeks big ideas for small in-space propulsion systems

Posted February 22, 2013 by

NASA’s Space Technology Program is calling for proposals to develop miniaturized electrospray propulsion technologies that could revolutionize small satellite propulsion systems. Electrospray thrusters use electricity to energize material and then disperse a resulting liquid or aerosol through an emitter to create thrust. The development of low-mass, lightweight micro thruster technologies has the potential to radically…

NASA’s Webb Telescope gets its wings

Posted March 22, 2013 by

A massive backplane that will hold the primary mirror of NASA’s James Webb Space Telescope nearly motionless while it peers into space is another step closer to completion with the recent assembly of the support structure’s wings. The wings enable the mirror, made of 18 pieces of beryllium, to fold up and fit inside a…
