Absfract-Group collaboration capabilities have been developed for Internet-based Mars rover mission operations. Internet-based operations enables scientists to participate in daily Mars rover mission operations from their home institutions. Group collaboration enables geographically separated users to collaboratively analyze downlinked data and plan new(More)
We have developed a new operator interface system for high-DoF articulated robots based on the idea of allowing the operator to extend the robot's actual kinematics with virtual articulations. These virtual links and joints can model both primary task DoF and constraints on whole-robot coordinated motion. Unlike other methods, our approach can be applied to(More)
The Mars Polar Lander (MPL) mission is the first planetary mission to w e Internet-based distributed ground operations where scientista and engineers cod labornte in daily mission operations f+om multiple geographically distributed locations via the Internet. This paper describes the operations system, the Web Interface for Telescience (WITS), which is used(More)
– 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)
– The Science Activity Planner (SAP) is the science planning tool used for the Mars Exploration Rover (MER) mission. This paper begins with an overview of the software developed for MER and how it was used for science downlink analysis and activity planning. The overview of SAP is then followed by a report on a number of new development efforts that aim to(More)
Cloud Computing has delivered unprecedented compute capacity to NASA missions at affordable rates. Missions like the Mars Exploration Rovers (MER) and Mars Science Lab (MSL) are enjoying the elasticity that enables them to leverage hundreds, if not thousands, or machines for short durations without making any hardware procurements. In this paper, we(More)
— We present an account of the scientific visual-ization 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)
— Effective data visualization is a key part of the discovery process in the era of " big data ". It is the bridge between the quantitative content of the data and human intuition, and thus an essential component of the scientific path from data into knowledge and understanding. Visualization is also essential in the data mining process, directing the(More)
