A small satellite levitates in a vacuum chamber used to test thruster design in the Space Propulsion Lab at MIT. Paulo Lozano is the Associate Director of the Space Propulsion Lab and an Associate Professor of Aeronautics and Astronautics at MIT in Cambridge, Massachusetts, USA. Lozano’s current research focuses on the development of small thrusters for satellites. The thrusters his lab has developed are about the size of a single die cube and contain enough fuel to power the thrusters for a year in space. The thrusters will be used on small satellites.
