All current cameras and imaging systems have the same classical problem in practical applications. To complete the observation task, a large amount of data is captured, processed, and transmitted; then most of the data is discarded because it is not essential for the given observation task. The problem comes from...

This Android app provides a native interface to the Lunar Mapping and Modeling Portal’s (LMMP) lunar data archive and analysis tools. It complements the iOS app previously released, incorporating a very similar feature set. Both apps contain a subset of the functionality available in the desktop/Web version. Compared to the iOS...

Amore efficient structural verification process for small satellites has been demonstrated. This new process eliminates the need for payload-specific coupled loads analysis (CLA) and simplifies structural testing while not increasing mission risk. The process...

The GOES-R Program has requirements to maintain knowledge of the GOES-R satellite onboard memory contents, including managing general satellite operations tables; processor memory dumps for memory verification; creating command loads, memory (table) loads, and command sequences to operate the satellite; verifying...

Modern spacecraft, aircraft, and surface vehicles support complex science missions in harsh environments. These spacecraft and vehicles provide diverse functionality that is deployed on increasingly complex and heterogeneous hardware and mechanical systems, with stringent...

A new method for optimizing yaw attitude maneuvers on the International Space Station (ISS) was developed. Docking and undocking operations often require 180° yaw rotations, which are the most common large maneuvers on the ISS. When optimized, some large maneuvers,...

NASA Engineering & Safety Center (NESC) subject matter experts analyze records in various International Space Station and shuttle databases to identify recurring anomalies. The key problems these experts face in analyzing such database records are:

The temperature of the orbiting space station’s Sun-facing side could be up to 250 °F (≈120 °C) and will be a significant antenna noise temperature contributor for visiting spacecraft communication and tracking systems during rendezvous....

An improved version of EXOS software allows for the modeling of fabrics, mixtures, and porous materials, and also provides the ability to accept hex mesh geometries. The code employs a novel numerical method, a hybrid particle finite element approach, as well as particles and elements in tandem, each modeling distinct aspects of the...

The requirements for advanced aircraft engine components lead to designs that are more lightweight and efficient, yet more susceptible to excessive vibration, complex dynamic behavior, and uncertain durability...

Auxiliary Payload Sensor System Simulation Software (APSSim) provides a simulation of the seismometer used in the Insight (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) mission. The software takes recorded or simulated APSS data as an input, preprocesses the input...

Data science is emerging as a critical area of research and technology to advance scientific discovery, knowledge, and decision-making through systematic computational approaches to analyzing massive data sets. The sheer volume of data increase, coupled...

This invention relates to a fluid film bearing and a process for evaluating pneumatic hammer instability. Based on the stability criteria, a method was developed using 3D CFD (computational fluid dynamics) evaluation dynamics to evaluate the onset of pneumatic...

This software allows sizing of submersibles powered by hydraulic generators that are pressurized by ocean thermal gradients at various depths. The software allows the operator to input the fixed size of the vessels containing the phase change material (PCM). The effective expansion of the PCM is also input,...

Seismometer Simulation Software (SEISim) is written to provide a simulation for the seismometer instrument in the Insight (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) mission so that flight software developers can use it to develop and test their software applications. It can...

Simulation study is an integral part of the validation of navigation algorithms for spacecraft. While it is possible to come up with an estimate of a navigation algorithm’s performance with a low-fidelity system model, the mathematical analysis is intractable...

AJava software program was developed that provides a solar system simulation, demonstrating the application of calculus to understanding and modeling how the real universe operates. The program can be modified by the user to study various changes in physical properties, and software...

The JLAB Tracking Tool (JTRAK) is a Web-enabled database tool designed to automate the tracking of James Webb Space Telescope (JWST) Integrated Ground Support System (IGSS) and Integrated Test Support System (ITSS) configured items. These configured items consist of IGSS and ITSS equipment and materials; hardware and...

The Wide Area Augmentation System (WAAS) broadcasts information that allows users to bound the positioning error that arises from ionospheric delay of signals emitted by Global Positioning System satellites. A critical objective of WAAS is to make ionospheric grid delays...
