Engineering changes and their propagation through a system provide insight into the complexity of a system. In an effort to identify systematic trends, we have analyzed two very different JPL-led space mission projects to classify the change activity and assess change propagation. The projects selected are a Mars lander mission, Mars Science Laboratory (MSL), and an Earth-orbiting mission, Soil Moisture...
New capabilities in spaceflight missions are enabled by new technologies. Transitioning new technology to spaceflight elements is difficult and introduces risk, but finding the right balance between benefit and risk leads to scientific advancements and novel space missions. A clear understanding of the risks of new technology can create an environment where innovation is nurtured rather than avoided...
We present sub-millimeter observations of the ground-state rotational transition (1 10 –1 01 ) of water vapor from Comet C/2002 T7 (LINEAR) obtained with the MIRO instrument on the ESA Rosetta spacecraft (s/c) orbiter on April 30, 2004. At the time of the observations, the comet was at a distance of 0.63AU from the Sun, 0.68AU from the MIRO telescope, and about 7.5days after its perihelion...
