XTour is a distributed software system used to design operating commands for the Visual and Infrared Mapping Spectrometer (VIMS) instrument onboard the Cassini spacecraft. The distributed architecture increases security and accessibility by centralizing access to the large datasets of information required to create instrument commands. Users are able to leverage portable devices to connect to the...
Recently the Cassini CAPS team investigated the number of different software tools, programming languages, programs, and major technologies used in building and running its ground system. A total of twenty six different tools, programs, and major technologies were used in the downlink portion of the ground system and five different tools, programs, and major technologies are used for the uplink portion...
NuSTAR, a NASA Small Explorer mission, is a high-energy astrophysics observatory targeted for an early 2012 launch into a low-inclination, low-Earth orbit. The science instrument is a focusing X-ray telescope developed by Caltech. Mission operations are conducted at Space Sciences Laboratory at the University of California, Berkeley, and science operations at Caltech. Integrated software systems provided...
This concept allows control of high-performance stepper motors with minimal parts count and minimal flight software complexity. Although it uses a small number of common flight-qualified parts and simple control algorithms, it is capable enough to meet demanding system requirements. Its programmable nature makes it trivial to implement changes to control algorithms both during integration & test...
To meet the requirement of high-speed data processing of complicated system with multi-sensor inputs and multi-controller outputs, an embedded ARM+FPGA +DSP multiprocessor platform is designed, which is characterized by synchronous cooperation and mutual exchange of shared data. ARM completes interface expansion and task scheduling configuring peripheral interfaces including RS422, CAN and RJ45, and...
The Advanced Planning and Scheduling Initiative, or APSI, is an ESA programme to design and implement an Artificial Intelligence (AI) software infrastructure for planning and scheduling that can generically support different types and classes of space mission operations. The goal of the APSI is twofold: (1)~creating a software framework to improve the cost-effectiveness and flexibility of mission...
This paper presents human-computer interaction (HCI) lessons learned over the course of design, development, and operation of activity planning tools on the Mars exploration rovers, the Phoenix Mars Lander, and looking ahead to the upcoming Mars Science Laboratory. These lessons and associated improvements to software tools range from challenging technical problems which require significant new software...
The space interferometry mission (SIM) under development at the Jet Propulsion Laboratory has been an ambitious project which when completed will determine the positions and distances of stars several hundred times more accurately than any previous program. This accuracy will allow SIM to determine the distances to stars throughout the galaxy and to probe nearby stars for Earth-sized planets. [1]...
This paper presents the operational concept for onboard processing for the HysIRI mission which is an Earth observing mission that includes both thermal infrared instrument and a hyperspectral visible/shortwave infrared instrument, and that is being considered for launch in the next decade. This article describes the potential application of AI techniques for the HyspIRI mission-for both onboard processing...
We describe a biologically-inspired approach to modeling self-adapting behavior of NASA swarm-based exploration missions, whereby individual entities in the system can sacrifice themselves for the greater good of the entire system. We investigate aspects of possible emergent self-adapting behavior of swarm-based systems, inspired by the self-sacrifice behavior observed in some hive cultures. Moreover,...
