Sensors

The goal of this work was to advance the development of new, extremely small (≈2 cm3), low-power (≈3 W), and low-cost micro mass spectrometer instrument systems (μMSIS) through the application of microelectro-mechanical system (MEMS) design and fabrication, and microsystem...

Many methods have been developed for interrogation of wireless passive sensors. Surface acoustic wave (SAW) sensors and RF reflection sensors can receive and reflect electronic magnetic waves that are broadcast and received by the antennas....

Structural health management systems that, by way of real-time monitoring, help mitigate accidents due to structural failures, will become integral technologies of the next-generation aerospace vehicles. Advanced sensor arrays and signal...

Optical detection of gaseous carbon dioxide, water vapor (humidity), and oxygen is desired in Portable Life Support Systems (PLSS) incorporating state-of-the-art CO2 scrubbing architectures. Earlier broadband detectors are nearing their end of life, and recent advances...

Extravehicular activities (EVAs) are dangerous to astronauts for a number of reasons, including high levels of physical exertion, potential for impacts by space debris particulates that could puncture the spacesuit and cause depressurization, Moon dust exposure that is...

The Community Coordinated Modeling Center (CCMC) provides a wide range of space weather tools and services for the general scientific community. One such product that facilitates space weather situational awareness is collectively known as the Integrated Space Weather Analysis...

The NASA Physical Oceanography Distributed Active Archive Center (PO.DAAC) is NASA’s designated data center for information relevant to the physical state of the ocean. Its core datamanagement and workflow system, Data Management and Archive System (DMAS), is responsible for processing hundreds of...

Flight testing is expensive. It is therefore important that necessary flight data be collected in the most efficient manner possible. Inputs traditionally used for flight test maneuvers to collect aircraft stability and control data include doublets, impulses (stick raps), multisteps, and...

The JPL CO2 Virtual Science Data Environment (VSDE) (http://co2.jpl.nasa.gov) is a comprehensive effort to bring together the models, data, and tools necessary for atmospheric CO2 research. The VSDE site is designed to provide streamlined Web-based discovery and access to multiple global and regional...

Advanced Microwave Precipitation Radiometer (AMPR) brightness temperature data from NASA field projects are in ASCII format. This Python script defines a class that will read in a single file from an individual aircraft flight and pull out timing, brightness temperatures from...

Observations in modern datasets have a continuum of quality that can be hard to quantify. For example, satellite observations are subject to often-subtle mixtures of confounding forces that distort the observation’s utility to a varying extent. For the Orbiting Carbon Observatory-2 (OCO-2)...

Advanced Rapid Imaging and Analysis for Earthquakes (ARIA-EQ) will be the first coordinated effort to automate geodetic imaging capabilities so they can be used for hazard response. The innovation is an automatic geodetic imaging data system that is the foundation for an operational hazard...

The Propellant Feed System Analytical Tool (PFSAT) predicts heat leak based on insulation type, installation technique, line supports, penetrations, and instrumentation. It also determines the optimum orifice diameter for an optional thermodynamic vent system (TVS) to counteract heat leak into the...
