OVEN & LAVA Subsystems in the RESOLVE Payload for Resource Prospector

A short briefing in Power Point of the status of the OVEN subsystem and the LAVA subsystems of the RESOLVE payload being developed under the Resource Prospector mission. The purpose of the mission is to sample and analyze volatile ices embedded in the lunar soil at the poles of the Moon and is expected to be conducted in the 2020 time frame

Impact of vorticity and viscosity on the hydrodynamic evolution of hot QCD medium

The strongly interacting transient quark-gluon plasma (QGP) medium created in ultra-relativistic collisions survive for a duration of a few fm/c. The spacetime evolution of QGP crucially depends on the equation of state (EoS), vorticity, viscosity, magnetic field, etc. In the present study, we obtain the QGP lifetime considering it as a 1+1-dimensionally (1+1) D expanding fluid by using second-order viscous hydrodynamics. We observe that the coupling of vorticity and viscosity significantly increases the lifetime of rotating QGP. Incorporating a static magnetic field along with vorticity and viscosity makes the evolution slower. However, for a non-rotating medium, the static magnetic field slightly decreases the QGP lifetime by accelerating the evolution process. We also report the rate of change of vorticity in the QGP medium, which can be helpful in studying the medium behavior in detail.Comment: 16 pages and 20 captioned figures. Submitted for publicatio

Paper Session I-A - Planning for the Performance of Future Space Bases

The United States Air Force and the Department of Defense are moving toward normalizing space operations, from specialized one-of-a-kind launch to standardized launch, much as they provide airlift today. Normalized launch will enhance our capability to meet contingency operations responsive to the rapidly changing world geopolitical situation. The current space infrastructure will not fully support future launch operation concepts. We must be more sensitive to environmental concerns, and improved performance standards are needed for future space facilities* The Air Force is taking the lead in bringing together the worldwide space community in developing a process for performance planning of future space bases

Evaluating the Use of Tribocharging in the Electrostatic Beneficiation of Lunar Simulant

Any future lunar base needs materials to provide thermal and radiation protection. Many factors point to the use of lunar materials as industrial feedstocks. Sintering of full-scale bricks using whole lunar dust has been accomplished. Refinement of soil beneficial before processing means less energy. Triboelectric separation of coal from minerals, quartz from feldspar, and phosphorous from silica and iron ore successively achieved. The Lunar environment ideal for electrostatic separation (1) lack of moisture (2) lower gravitational pull (3) higher voltages in vacuu

Incorporation of Chemochromic Pigment into a Variety of Articles as an Indicator for the Presence of Hypergolic Fuels

A chemochromic indicator is provided that includes a hypergolic fuel sensing chemochromic pigment that change from a first color to a second color in the presence of a hypergolic fuel. In a first embodiment, a chemochromic indicator is provided for detecting the presence of a hypergolic fuel such that the irreversible hypergolic fuel sensing chemochromic pigment includes potassium tetrachloroaurate (KAuCl.sub.4). There are several types of chemochromic indicators, for example, the article used to form the chemochromic indicators include, but are not limited to, wipe materials, silicone/TEFLON tape, manufactured parts, fabrics, extruded parts, and paints

Color Changing Hydrogen Sensors

During the Space Shuttle Program, one of the most hazardous operation that occurred was the loading of liquid hydrogen (LH2) during fueling operations of the spacecraft. Due to hydrogen's low explosive limit, any amount leaked could lead to catastrophic event. Hydrogen's chemical properties make it ideal as a rocket fuel; however, the fuel is deemed unsafe for most commercial use because of the inability to easily detect the gas leaking. The increased use of hydrogen over traditional fossil fuels would reduce greenhouse gases and America's dependency on foreign oil. Therefore a technology that would improve safety at NASA and in the commercial sector while creating a new economic sector would have a huge impact to NASA's mission. The Chemochromic Detector for sensing hydrogen gas leakage is a color-changing detector that is useful in any application where it is important to know not only the presence but also the location of the hydrogen gas leak. This technology utilizes a chemochromicpigment and polymer matrix that can be molded or spun into rigid or pliable shapes useable in variable temperature environments including atmospheres of inert gas, hydrogen gas, or mixtures of gases. A change in color of the detector material indicates where gaseous hydrogen leaks are occurring. The irreversible sensor has a dramatic color change from beige to dark grey and remains dark grey after exposure. A reversible pigment changes from white to blue in the presence of hydrogen and reverts back to white in the presence of oxygen. Both versions of the sensor's pigments were comprised of a mixture of a metal oxide substrate and a hydro-chromic compound (i.e., the compound that changed color in the presence of hydrogen) and immediately notified the operator of the presence of low levels of hydrogen. The detector can be used in a variety of formats including paint, tape, caulking, injection molded parts, textiles and fabrics, composites, and films. This technology brings numerous benefits over the traditional hydrogen sensors: The technology has excellent temperature stability (4K to 373 K), it can be used in cryogenic fluid applications, it is easy to apply and remove; it requires no power to operate; it has a quick response time; the leak points can be detected visually or electronically; it is nonhazardous, thus environmentally friendly; it can be reversible or irreversible; it does not require on-site monitoring; has a long shelf life; the detector is very durable; and the technology is inexpensive to manufacture

Chemochromic Detector for Sensing Gas Leakage and Process for Producing the Same

A chemochromic sensor for detecting a combustible gas, such as hydrogen, includes a chemochromic pigment and a textile polymer. The textile material includes a chemochromic pigment operably responsive to a combustible gas. The combustible gas sensing textile material can be made by melt spinning, solution spinning, or other similar techniques. In a preferred embodiment carbon nanotubes are used with the textile material which will increase the material strength and alter the thermal and/or electrical properties. These textiles woven into fabrics can provide garments not only with hydrogen sensing capabilities but the carbon nanotubes will allow for a range of sensing capabilities to be embedded (i.e. gas, health, and electronic monitors) within the garments
