The Common Access Manager (CAM) software was developed to control access to functions and data for mission control, telemetry, tracking, instrument data, and other ground data system capabilities. The CAM software is used by Advanced Multi-Mission Operations System (AMMOS) and Deep Space Network (DSN) subsystems,...

Current human spaceflight requirements limit the number of hours a crewmember can be outside of the habitation unit to 8 hours in a 48-hour period, and 24 hours in a seven-day period. This time must be appropriately balanced to complete science, exploration, and maintenance tasks. Off-days can be used for site transit...

Architecture development often is conducted prior to system concept design when there is a need to determine the best-value mix of systems that works collectively in specific scenarios and time frames to accomplish a set of mission area objectives. Conducted prior to Pre-Phase A of the...

The Internet Engineering Task Force (IETF) standardized Bundle Protocol (BP) enables data transfer using “bundles” over a Delay/Disruption Tolerant Network (DTN). BPTables is a bundle filtering framework that enables the establishment of barriers between more and less trusted BP network domains, and...

This week’s Question: A new "CarNote" app from the Eindhoven University of Technology in the Netherlands aims to use augmented reality to improve the driving experience and reduce "road rage." CarNote's driver-facing periscope lens and transparent display projects information from a smartphone, allowing...

Model-based diagnosis deals with the problem of diagnosing faults in systems using a model of the system for guidance. This problem is complicated by the presence of hybrid dynamics in the system (continuous evolution of the system interspersed with discrete events like commands to...

Concept design plays a central role in project success for space missions, as the product of concept design effectively locks in the majority of system lifecycle cost. It involves a concurrent investigation of requirements and multiple mission characteristics...

Due to limitations imposed by transistor physics as device geometries continue to get finer and finer, the time when each new generation of processors was clocked faster than its predecessors is largely over. Nevertheless, as individual processor cores get smaller, chip manufacturers have turned instead to...

The Jet Propulsion Laboratory's Institutional Budgeting Tool (IBT) was designed and developed to meet the needs of JPL's budget planners, numbering 1,600, who required a robust and state-of-the-art budgeting application. JPL's budgeting process had been constrained by legacy tools that presented usability and...

Java PathFinder (JPF) version 7 provides basic support for verifying the distributed Java applications. It can receive a distributed Java application as input that is perceived as multiple Java processes. However, JPF does account for communication between processes of the distributed application, and it thus...

The Matlab Webification Science Client consists of several functions that access remote w10n-sci repositories to retrieve data. It supports user sessions to authenticate and authorize access to restricted repositories. In command line mode, it can list the contents of a w10n-sci node, change to other nodes, and...

Many natural or complex engineered systems rely upon critical functions or processes that can be measured with the aid of various sensors or other novel devices. As a result, sensor and measurement data can be used to learn a parametric or non-parametric model of the behavior for a...

The Space Communications and Navigation (SCaN) program is responsible for providing communications and navigation services to spaceflight missions located throughout the solar system. Astronauts, mission controllers, and scientists depend upon the reliable transmission of information between...

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major...
