Traceable Automation with Remote Display and Interruptible Scheduler Version 1.04.0

Many complex procedures can be completed more quickly, under controlled conditions, and without human intervention or error. NASA’s Jet Propulsion Laboratory, Pasadena, California Traceable Automation with Remote Display and Interruptible Scheduler (TARDIS) is a software set designed for use in ground operations. TARDIS is a multi-mission automation framework that supports seamless integration of manual and automatic processing. It was developed to automate mission design and navigation (MDN) procedures, but is general enough to automate many other kinds of procedures as well. It allows users to define the tasks to run and the circumstances under which to run them. Thereafter, TARDIS watches the entire host computer and automatically runs the corresponding tasks as conditions change. It also watches the tasks as they run and logs their results. It provides a graphical user interface (GUI) front end, so users can monitor and control system state and task progress from any Web browser. As a result, many complex procedures can be completed more quickly, under controlled conditions, and without human intervention or error.

Java Pathfinder (JPF) Core System

Ames Research Center, Moffett Field, California The JPF Core System is a framework to analyze and verify Java bytecode programs. The major component of JPF core is an extensible and runtime-configurable virtual machine (VM) that can be customized with runtime components such as specific instruction sets and plug-ins to observe program execution. The JPF core can store and restore program states, and comes with a configuration that constitutes a standalone software model checker that can be used to detect and analyze concurrency defects in Java applications like deadlocks or data race conditions.

Single Doppler Retrieval Toolkit (SingleDop)

Marshall Space Flight Center, Alabama Single-Doppler retrieval of low-level, two-dimensional winds is desired to compare ground radar wind retrievals to satellite scatterometer wind retrievals. This needs to be integrated within the growing collection of open-source radar tools maintained by the Python Atmospheric/Ocean Sciences (PyAOS) community. SingleDop is a software module written in Python that retrieves 2D, low-level winds from either real or simulated Doppler radar data.

Computing Efficient Onboard Analysis and Re-Scheduling

The objective is to speed up the responsiveness to onboard decision-making. NASA’s Jet Propulsion Laboratory, Pasadena, California Prior space missions have not routinely used onboard decision-making. The Autonomous Sciencecraft (ASE), flying onboard the Earth Observing One spacecraft, has been flying autonomous agent software for the past decade that enables it to analyze acquired imagery onboard, and use that analysis to determine future imaging. However, ASE takes approximately one hour to analyze and respond.

Tool for Rapid Analysis of Monte Carlo (TRAM) Simulation Data

This tool can be used in any engineering industry that uses Monte Carlo simulations as part of a design and analysis process. Lyndon B. Johnson Space Center, Houston, Texas Spacecraft design is inherently difficult due to the complexity of the systems involved and the expense of testing hardware in a realistic environment. The number and cost of flight tests can be reduced by performing extensive simulation and analysis studies to understand vehicle operating limits and identify circumstances that lead to mission failure. A Monte Carlo simulation approach that varies a wide range of parameters is typically used to generate a large set of test scenarios. The results of these analyses bound the vehicle performance and eventually help certify a spacecraft for flight.

Object-Oriented FITS File Interface for MATLAB

Goddard Space Flight Center, Greenbelt, Maryland The ability to read complicated Flexible Image Transport System (FITS) files in MATLAB was required for analyzing data from the Integrated Science Instrument Module (ISIM) cryovac test campaign for the James Webb Space Telescope (JWST) project. This software was written to fill that specific need, but is more generally applicable.
