NASA Milestone progress is being made in readying NASA’s Green Propellant Infusion Mission (GPIM) for launch in 2016, a smallsat designed to test the unique attributes of a high-performance, non-toxic, “green” fuel on orbit. The GPIM marks the first time the United States will use a spacecraft to test green propellant technology, thereby showcasing the innovation needed to develop a fully domestic, green propellant solution for the next generation of space flight. GPIM is a...

Kim Henry, Marshall Space Flight Center As progress continues on NASA's new rocket, the Space Launch System (SLS), the solid rocket boosters team successfully completed its critical design review Aug. 6. This is an important milestone for the program, as it verifies the boosters are ready to move forward with qualification testing. The two five-segment solid rocket boosters will provide the majority of the liftoff thrust for the SLS vehicle. As the SLS evolves, it will be used for deep...

redOrbit Staff & Wire Reports - Your Universe Online An experimental microwave thruster that does not require fuel to operate has been dubbed the “impossible” space engine, but a team of NASA researchers has reportedly confirmed the system actually works. According to Mike Wall of Space.com, researchers from the US space agency’s Houston-based Johnson Space Center evaluated the system and found that it actually is capable of generating a small amount of thrust. If this is...

ESA ESA’s Venus Express spacecraft has climbed to a new orbit following its daring aerobraking experiment, and will now resume observations of this fascinating planet for at least a few more months. The orbit-raising followed a month of aerobraking that saw the spacecraft surf in and out of the atmosphere at altitudes typically between 131 km and 135 km for a couple of minutes on each of its closest approaches to the planet. Before, normal operations involved an elliptical orbit...

Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...
