Schaffer, Steve; Chien, Steve; Ferguson, Eric, 2018, "Validation of Fault-Tolerant Plans for Europa Clipper", https://hdl.handle.net/2014/48265, International Symposium on Artificial Intelligence Robotics and Automation in Space (i-SAIRAS) 2018, Madrid, Spain, June 4 - 6, 2018, JPL Open Repository
The Europa Clipper mission will explore that icy moon in a series of brief flybys through the Jovian radiation belts. A single event upset in the spacecraft flight computer during these critical scientific periods could jeopardize the success of the mission. Rather than safing and aw... |

McLaren, David; Doubleday, Joshua; Chien, Steve, 2012, "Using WorldView-2 imagery to track flooding in Thailand in a multi-asset sensorweb", https://hdl.handle.net/2014/42594, SPIE Algorithms and technologies for multispectral, hyperspectral, and ultraspectral imagery XVIII : Baltimore, Maryland, April 23-27, 2012, JPL Open Repository
For the flooding seasons of 2011-2012 multiple space assets were used in a “sensorweb” to track major flooding in Thailand. Worldview-2 multispectral data was used in this effort and provided extremely high spatial resolution (2m / pixel) multispectral (8 bands at 0.45-1.05 μ m s... |
