NASA's Flight Opportunities Program has selected 24 cutting-edge space technology payloads for flights on commercial reusable launch vehicles, balloons and a commercial parabolic aircraft. Sixteen of the payloads will ride on parabolic aircraft flights, which provide brief periods of weightlessness. Five will fly on suborbital reusable launch vehicle test flights. Two will ride on high-altitude balloons that fly above 65,000 feet. One payload will fly on the suborbital launch vehicle and...

A sub-scale solid rocket motor designed to mimic NASA's Space Launch System, or SLS, booster design successfully was tested today by engineers at NASA's Marshall Space Flight Center in Huntsville, Ala. The 20-second firing tested new insulation materials on the 24-inch-diameter, 109-inch-long motor. The motor is a scaled down, low-cost replica of the solid rocket motors that will boost SLS off the launch pad. Marshall is leading the design and development of the SLS on behalf of the...

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...
