This will be accomplished through the use of a constellation of small payloads that separate relative to each other throughout a sounding rocket flight. The multiple baseline observations of the electric and magnetic fields will be used to observe variability of both the E-field and the Poynting flux. These observations will be placed in the context of available data, including winds, large scale E-fields, and proxy conductivity (airglow images) observations. In this way we will address the main scientific objective of this mission which is: What are the contributions of small spatial scale and rapid temporal scale fluctuations of electric fields relative to the larger-scale electrodynamic processes? The high altitude rocket will be launched along the magnetic field line and carry six sub-payloads to be ejected from the main payload at high velocity. The sub-payloads will be deployed both along the flight path and perpendicular to the flight path so that both spatial features and temporal-spatial ambiguities can be explored. The low-mass sub-payloads that, for a fixed ejection impulse will achieve at least a 50 km separation by the end of the flight are key to the observational success. Each sub-payload will carry a crossed pair of double-probe sensors to measure in-situ electric fields, a three axis magnetometer, a Langmuir probe and a GPS receiver. In this poster we review the ASSP science and mission concepts.</p> <p>  </p> <p>  </p>

"Summary: The Laser Interferometer Space Antenna (LISA) mission is under consideration by NASA and ESA as a joint mission to study gravitational wave signals from a number of types of astrophysical sources at frequencies below 1 Hertz. These include mergers of massive black hole binaries out to redshifts of 10 or more and inspirals of stellar mass black holes into galactic center black holes at redshifts out to about 1. Extremely sensitive tests of the predictions of general relativity will be tested under highly relativistic conditions by the measurements. Two dual-cylinder resonant cavities for laser stabilization which are suitable for hard-mounting in spacecraft have been designed and constructed under previous NASA support. Evaluation and testing of these cavities now is being started under NASA Award NNX09AD11G. The cavities have been designed to have substantially reduced sensitivity to vibrations and to temperature variations at frequencies above 1 millihertz. The relative frequencies for the two cavities in their separate small vacuum chambers will tested under a range of different conditions. In addition, a search will be made for occasional small glitches in the phase of lasers locked to the two cavities, which could cause temporary disturbances in the LISA measurements if they occurred too frequently. It now has become clear that the desired range of measurements on the cavities can't be completed by the end of the present funding period. Thus funding is requested under this proposal for two additional semesters of support for a graduate student in order to complete the desired measurements. The category under which this proposal is being submitted is Supporting Technology."

<p> Microcalorimeter x-ray instruments are non-dispersive, high spectral resolution, broad-band, high cadence imaging spectrometers. We have been developing these instruments for x-ray astrophysics for over 25 years and have successfully flown them on both suborbital and orbital observatories. Microcalorimeter spectrometers are true spatial-spectral event-driven instruments. The core instrument for the Astro-H observatory to be launched in 2014 and for the International X-ray Observatory planned for around 2022 [1] are both microcalorimeter spectrometers. For the past two years, supported by the Solar and Heliospheric ROSES program, we have been adapting this highly successful technology to the very different requirements of solar physics. This leverages the large NASA investment in this technology to produce instruments optimized for solar physics with only a moderate development program.</p> <p> During the past two years, we have developed a high spatial resolution, high cadence microcalorimeter optimized for solar observations with a ground-breaking spectral resolving power of nearly 3000 at 6 keV. This exceeds the performance goals of our program. In fact, the single-pixel performance achieved during this program is already sufficient for a solar optimized instrument as described in section 2, albeit using small arrays of detectors. We propose here to continue this successful program by developing large focal-plane arrays, optimized for solar physics and their read-out systems. This complements our existing development programs in astrophysics, where we have already produced and tested kilo-pixel arrays for IXO. The end-result of the proposed work will be a solar-optimized detector system proven and ready for integration into a suborbital payload and then onto a space-borne observatory. Both the suborbital program and an orbital instrument would allow high cadence spatial-spectral observations across the x-ray band from 0.1 to above 10 keV, enabling new science as described in section 1.4. Ultimately this will produce instrumentation suitable for deployment on an Explorer-class mission and, possibly, a remote sensing contribution to the Solar Energetic Particle Acceleration and Transport (SEPAT) Solar-Terrestrial Probe [2].  </p>

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

Summary

Description

Activities advance the development of scientific instruments or instrument components to the point where the instruments could credibly be proposed in response to future flight opportunity announcements, including instruments that could be accommodated on or in small satellites (under 50kg total spacecraft mass), or as small payloads in support of future science activities associated with missions of human exploration (proposals to build and fly hardware on a specific mission opportunity are not a part of this program element and the development of instruments for use in future field campaigns is under ASTEP). The scientific goals and objectives of NASA?s Astrobiology program are described in the Astrobiology Roadmap that is available on the Astrobiology web site at http://astrobiology.arc.nasa.gov/roadmap. Instrumentation and astrobiology mission concepts developed from research supported through this ASTID program element are meant to address two fundamental questions in Astrobiology, namely, ?How does life begin and evolve?? and ?Does life exist elsewhere in the Universe?? Objectives that could be addressed by new spacecraft instrumentation and astrobiology small payload missions include, for example: ? To determine whether the atmosphere of the early Earth, hydrothermal systems, or exogenous matter were significant sources of organic matter; ? To search for evidence of ancient climates, extinct life, and potential habitats for extant life on Mars; ? To determine the presence of chemical precursors and potential habitats for life in the outer Solar System; and ? To determine if compounds of biological significance are present beyond our Solar System.

This point file displays the 727 vegetation plots and 217 observation points visited in 2002, 2003 and 2004 as part of the vegetation mapping project. Plots and observation points were located subjectively in representative vegetation throughout the park. Field crews decided where and when to use observation points or vegetation plots to sample the vegetation. Vegetation plots were placed in stands judged by field crews to represent legitimate vegetation types that could be classified to the National Vegetation Classification (NVC) system using standard multivariate analysis techniques. Observation points were placed in stands (1) if the vegetation was highly altered and therefore not classifiable, (2) to provide information about the distribution of common vegetation types adequately sampled in vegetation plots, or (3) if the stand represented a unique vegetation type that was too small to hold a 400m2 sample plot (e.g., seeps, hanging gardens). The points were originally GPSed (using recreational GPS units), coordinates noted on the field sheets and then typed into the database. Field photos are associated with each plot.
