The Electric and Magnetic Field Instrument Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named Van Allen Probes) mission provides key wave very low frequency magnetic field measurements to understand radiation belt acceleration, loss, transport. science objectives contribution that EMFISIS makes providing as well theory modeling are described. components of instruments suite, both electronics sensors, including functional parameters, calibration,...
The Sample Analysis at Mars (SAM) investigation of the Science Laboratory (MSL) addresses chemical and isotopic composition atmosphere volatiles extracted from solid samples. SAM is designed to contribute substantially mission goal quantitatively assessing habitability as an essential step in search for past or present life on Mars. a 40 kg instrument suite located interior MSL's Curiosity rover. instruments are quadrupole mass spectrometer, tunable laser 6-column gas chromatograph all...
The MAVEN magnetic field investigation is part of a comprehensive particles and fields subsystem that will measure the electric plasma environment Mars its interaction with solar wind. instrumentation consists two independent tri-axial fluxgate magnetometer sensors, remotely mounted at outer extremity arrays on small extensions ("boomlets"). sensors are controlled by functionally identical electronics assemblies integrated within draw their power from redundant supplies system. Each measures...
The Juno Magnetic Field investigation (MAG) characterizes Jupiter's planetary magnetic field and magnetosphere, providing the first globally distributed proximate measurements of Jupiter. instrumentation consists two independent magnetometer sensor suites, each consisting a tri-axial Fluxgate Magnetometer (FGM) pair co-located imaging sensors mounted on an ultra-stable optical bench. system are part subsystem that provides accurate attitude information (to ∼20 arcsec spinning spacecraft)...
Abstract NASA's Parker Solar Probe (PSP) mission is currently investigating the local plasma environment of inner heliosphere (<0.25 R ⊙ ) using both in situ and remote sensing instrumentation. Connecting signatures microphysical particle heating acceleration processes to macroscale heliospheric structure requires sensitive measurements electromagnetic fields over a large range physical scales. The FIELDS instrument, which provides PSP with corona, includes set three vector magnetometers:...
The island of Lanzarote (Canary Islands) is widely recognized as a terrestrial analog for planetary science due to its geological and environmental characteristics. This hosts numerous lava tubes, including the 7.6-km-long La Corona tube, one Earth&#8217;s largest. Detecting tubes other subsurface cavities crucial exploration, they may be used safe shelters in future missions.&#160;Magnetic data, scalar vector magnetometer data well magnetic susceptibility measurements, were...
GTOSat is a 6U CubeSat mission that will pave the way for highly reliable, capable constellations and missions beyond low Earth orbit (LEO). study Earth’s dynamic radiation belts, acting as follow-on to NASA’s Van Allen Probe demonstrating potential utility of SmallSats both science space weather monitoring. While number previous CubeSats have studied belts from LEO, launch into inclination geosynchronous transfer (GTO) directly sample core trapped particle population. From this orbit, it...
A lthough cases of pile distress and fatigue have been noted in several severe recent earthquakes, most them occurred as a result deficiencies design due to inadequacies soil analysis or overall building design. None the failures observed, incidentally, used prestressed concrete piling their construction. Nonetheless, demonstrate that should possess ductility at certain key locations, current provisions for are some inadequate. Observations performance Anchorage, Alaska (1964-8.4 Richter...
The Gamma Ray Large Area Space Telescope (GLAST) (LAT) is a pair-production high-energy (>20 MeV) gamma-ray telescope being built by an international partnership of astrophysicists and particle physicists for satellite launch in 2006, designed to study wide variety astrophysical phenomena.As part the development effort, collaboration has Balloon Flight Engineering Model (BFEM) flight on high-altitude scientific balloon.The BFEM approximately size one 16 GLAST-LAT towers contains all components
We describe an innovative detector designed primarily for the study of cosmic gamma-ray bursts aboard interplanetary spacecraft. The experiment is a fully functional, low cost, mass, low-power instrument, which, when combined with other similar instruments, has capability localizing to arcminute precision. burst monitor based on photomultiplier tube and plastic/CsI(Tl) phoswich records photons in 20-150-keV energy range time resolutions up several milliseconds. In addition, it photon...
Shadow imaging is a technique to obtain highly resolved silhouettes of resident space objects (RSOs) which would otherwise be unattainable using conventional terrestrial based approaches. This done by post processing the measured irradiance pattern (shadow) cast onto Earth as RSO occults star. The research presented here focuses on recent developments in shadow geosynchronous (GEO) satellites with near stationary orbits approximately 36,000 km from Earth. fundamental resolution limits are...
A modular, UNIX/X-Windows/Sun SPARC-based data acquisition and analysis system provides NASA X-Ray Timing Explorer (XTE) Proportional Counter Array (PCA) scientists with near real-time access to space flight instrument ground test data. This processes directly from five large-area, xenon-filled low-background collimated proportional counters at rates up 2 MB/s in a networked, environment. Science events are sent serially the counter electronics multiplexed on custom-designed board. Each...
The renewal of the Ulysses mission to year 2001, and failure Mars Observer, once more leave Interplanetary Network with only two widely spaced components. We have therefore developed begun build a small GRB detector for Russian ’96 mission. first flight unit has now been delivered Russia spacecraft tests. Three interesting features this experiment are first, that it measures both particles gamma rays, second, is not much larger than Walkman (hence name), third, being constructed support from...
