NASA Announces Next Opportunity for CubeSat Space Missions

"CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh about 3 pounds."

Keith's note: Inches? Quarts? Pounds? What happened to the NASA policy directing the use metric units? Curiously, if you read the official CubeSat Design Specification Rev. 12, from California Polytechnic State University (an American educational institution) the specs are in metric units. So has someone@NASA.gov gotten yet another waiver to not use of metric units in their program? Or is this another PAO author being lazy? Then again, it was this confusion over units of measure that allowed Mars Climate Orbiter to make a surprise landing on Mars.

Assessment of NASA's Use of the Metric System, G-00-021 (2001)

"Following the loss of the Mars Climate Observer, the NASA Office of Inspector General initiated a review of the Agency's use of the metric system. By law and policy, the metric system is the preferred system of measurement within NASA. However, our review found that use of the metric system is inconsistent across the Agency. A waiver system, which was required by law and put into effect to track metric usage and encourage conversion, is no longer in use."
