A theme that has come to the fore in advanced planning for long-range space exploration is the concept of "propellantless propulsion" or "field propulsion." One version of this concept involves the projected... more
Abstract. The microwave thermal thruster heats propellant via a heat-exchanger then expands it through a rocket nozzle to produce thrust. The heat-exchanger is simply a microwave-absorbent structure through which propellant flows in small... more
Since the STS-114 mission in August of 2005, the FAA has partnered with NASA to protect aircraft flying in the National Airspace System from the potential hazards associated with a catastrophic failure of a reentering Space Shuttle... more

A general relativistic scenario is utilized to build a non-perturbative model, in Schwarzschild metric, for the rep- resentation of observed angles among star pairs. This model is then applied to an end-to-end simulation of the GAIA... more

The first satellite Sputnik came about in 1957, the law regulating activities in outer space came in a decade later. The law was then dynamic and evolved to fulfill the changing needs of the world. Quite unfortunately, it stopped evolving... more
The SuperNova / Acceleration Probe (SNAP) is a space-based experiment to measure the expansion history of the Universe and study both its dark energy and the dark matter. The experiment is motivated by the startling discovery that the... more
Structural health monitoring (SHM) is certainly one of the key technologies required to achieve the goal for new space vehicles of having reduced maintenance costs with increased levels of safety. For the time being, sensor technology has... more
