Two main innovations will be developed in the Phase II effort that are fundamentally associated with our gaseous oxygen/gaseous methane RCS thruster. The first innovation is that of an integrated torch igniter/injector which, provides simple and reliable ignition for the thruster. The second innovation is the thruster's capability to operate with both gaseous and liquid propellants. This innovation enables greater system flexibility that is inherent in the capacity to function over a much wider range of operating conditions. Orion has been approached by several prospective customers concerning affordable, reusable thrusters. In the current commercial market, this does not exist and the commercial sector cannot afford traditional propulsion solutions. For this reason, Orion started developing a thruster that offers the following features: ? Provides an affordable solution as compared to what is currently available ? Uses a different manned approach since it is reusable ? Uses a modular design, which allows for the robust inspection and replacement of parts ? Uses green propellants and capitalizes on in situ propellant production ? Provides greater system flexibility since it operates with both liquid and gaseous propellants Not only does the gas/gas operation of the thruster attract companies such as t/Space and Bigleow Aerospace, but its liquid/liquid operation broadens this customer base and makes this design applicable to NASA programs such as the Crew Exploration Vehicle (CEV).

This data set consists of water chemistry data from streams, wells, rainwater, and canopy throughfall samples. The field measurements were carried out at Rancho Grande in the Brazilian state of Rondonia, in the southwestern Brazilian Amazon basin, at two adjacent watersheds, a forest (1.37 ha), and pasture (0.73 ha). Samples were collected during one entire rainy season starting in August 2004 and ending in April 2005. There is one comma-delimited data file with this data set.Ridge, Tennessee, U.S.A.

Bathythermograph data were collected from the BIBB within a 1-mile radius of Ocean Weather Station B (56305N 05100W) and in transit. Data were collected by the United States Coast Guard from 20 September 1965 to 11 October 1965. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

Popis
A tunable dye laser for Lidar detection will be fabricated based on the innovative dye-doped Holographic Polymer Dispersed Liquid Crystals (HPDLC) technology. The demonstration of the tunable lasing of dye-doped holographic polymer dispersed liquid crystal is the main focus during the Phase-I research, while the commercial tunable-laser product will be realized in Phase-II. By carefully choosing the materials including liquid crystal, UV-polymerizable monomer, emitter dye and optimizing the holographic-writing process, dye-doped HPDLC is formed as an one-dimensional photonic bandgap material, Mirrorless Lasing in the dye-doped HPDLC occurs at the reflection band edges. Applied voltage tunes the reflection peak of the HPDLC as well as the center wavelength of emitting laser. The whole laser device is solid state and highly resistant to shock and vibration as it has no moving parts. Since the innovative laser device is based on the thin film technology, there is no bulky laser cavity and the cost of the HPDLC thin films are low due to easy-to-achieve large scale manufacturing. The unit price of the HPDLC thin film can be so low that it is economical to throw away and replace a HPDLC thin film device once the dye reaches the end of its life.
