This paper presents an introduction to the CLEAR system which performs rover command generation and re-planning, the challenges faced maintaining domain specific information in an uncertain environment, and the successes demonstrated with several methods of system testing.
This paper provides a brief overview of the entire OASIS system and how it analyzes one type of data - grayscale images taken by the rover for engineering and hazard avoidance purposes.
In this paper, we describe the OASIS system, which provides autonomous capabilities for dynamically pursuing these science-collection opportunities during long-range rover traverses.
This paper presents arguments for a balanced approach to modelling and reasoning in an autonomous robotic system. The framework discussed utilizes both declarative and procedural modelling to define the domain, rules, and constraints of the system and also balances the use of deliberative and reactive reasoning during execution.
This paper describes how continuous planning and execution techniques can be used to perform intelligent decision-making for an autonomous Mars rover.

The Deep Space Station Controller (DSSC) is state of the art ground station control architecture being developed at JPL. During the past few years the technology development program at JPL demonstrated a series of increasingly competent automated ground station prototypes of which the DSSC is the latest. It has been designed for robust closed loop control of ground stations utilized for forward and return link communications with NASA's deep space exploration missions.
This article describes a number of lessons learned in deploying automated planning and scheduling systems for space applications at the Jet Propulsion Laboratory.
In this paper, we describe the three major areas for autonomous systems for space exploration: free-flying spacecraft, planetary rovers, and ground communications stations.
In recent years with the large increase in the number of space missions at NASA, the demand for deep space communications services to command and collect data from these missions has become more difficult to manage.
This paper describes the ASPEN system for automation of planning and scheduling for space mission operations.
In recent years with the large increase in the number of space missions at NASA and JPL (Jet Propulsion Laboratory), the demand for deep space communications services to command and collect data from these missions has become more difficult to manage.
In recent times, improvements in imaging technology have made available an incredible array of information in image format.
This paper describes an architecture for an autonomous deep space tracking station (DS-T).
