The Science Activity Planner (SAP) is the primary science operations tool for the Mars Exploration Rover mission and NASA’s Software of the Year for 2004. SAP utilizes a variety of visualization and planning capabilities to enable the mission operations team to direct the activities of the Spirit and Opportunity rovers. This paper outlines some of the(More)

Search engines have become a crucial tool for finding information in repositories containing large amounts of textual data in unstructured form (e.g., the Web). However, the task of ad hoc information retrieval, that is, finding documents within a corpus that are relevant to an information need specified using a query, remains a hard challenge. The language(More)
—The science activity planning process for the 2003 Mars Exploration Rover (MER) mission was exercised in a ten day terrestrial rover field test in August 2002. A version of the MER mission Science Activity Planner (SAP) tool was used for downlink data visualization and uplink plan generation. The Field Integrated Design and Operations (FIDO) rover was at(More)
We present an account of the scientific visualization techniques that were used to support science planning for NASA's 2003 Mars Exploration Rover Mission. The great sophistication of the rover's Athena Science Payload required a wide variety of visualization modalities to make the large amounts of scientific data accessible and readily understood by the(More)
— The unprecedented endurance of both the Spirit and Opportunity rovers during the Mars Exploration Rover Mission (MER) brought with it many unexpected challenges. Scientists, many of whom had planned on staying at the Jet Propulsion Laboratory (JPL) in Pasadena, CA for 90 days, were eager to return to their families and home institutions. This created a(More)
We performed 2D and full 3D magnetohydrodynamic simulations of disk accretion to a rotating star with an aligned or misaligned dipole magnetic field. We investigated the rotational equilibrium state and derived from simulations the ratio between two main frequencies: the spin frequency of the star and the orbital frequency at the inner radius of the disk.(More)
