Abstract: A system enabling safe manned and unmanned operations at extremely high altitudes (above 70,000 feet). The system utilizes a balloon launch system and parachute and/or parafoil recovery.

Abstract: This disclosure provides water processing apparatuses, systems, and methods for recovering water from wastewater such as urine. The water processing apparatuses, systems, and methods can utilize membrane technology for extracting purified water in a single step. A containment unit can include an ionomer membrane, such as Nafion®, over a hydrophobic microporous membrane, such as polytetrafluoroethylene (PTFE). The containment unit can be filled with wastewater, and the hydrophobic microporous membrane can be impermeable to liquids and solids of the wastewater but permeable to gases and vapors of the wastewater, and the ionomer membrane can be permeable to water vapor but impermeable to one or more contaminants of the gases and vapors. The containment unit can be exposed to a dry purge gas to maintain a water vapor partial pressure differential to drive permeation of the water vapor, and the water vapor can be collected and processed into potable water.

Abstract: A system of spacecraft radiators comprising pre-formed thermal-transfer modules joined together by at least one solid-state welding process. Critical failure points are eliminated by forming the thermal-transfer modules as a single unitary piece, preferably by an extrusion process. The thermal-transfer modules allow the formation of larger radiator assemblies, which may comprise a wide range of sizes and physical geometries.

Abstract: Systems and methods utilizing water-vapor-partial-pressure-differential across a chemically-selective membrane to remove water vapor from a habitable spacecraft environment(s). The system preferably utilizes heat from an exothermic CO2 removal process to prevent condensation at the chemically-selective membrane.

Abstract: A system designed to increase diver safety in high-risk environments containing one or more hazardous materials. The system comprises one or more retrofittable kits enabling the upgrading of contaminate-vulnerable materials of an existing dive helmet to provide full environment isolation for the diver. The system preferably utilizes fluoroelastomeric replacement materials and components to convert an open circuit dive system to a closed circuit dive system. Methods of system development are also disclosed.

Abstract: A ground-based system for simulating dynamic suborbital-flight environments occurring during substantially complete suborbital-flights by a flight vehicle.

Abstract: An air sampling and analysis system has a plurality of air sampling tubes extending between an analytical laboratory and a number of remote locations where samples are taken. Means are provided for continually drawing air through the sampling tubes during times when they are not connected to a analytical instrument for measuring concentration of various gases. Means are also provided adjacent to the inlet of at least some of the sampling tubes for converting a vapor which may not travel the full length of the sampling tube, to a gas which will travel the full length of the tube. The concentration of the vapor can be found by measuring the composition of the air sample with conversion and subtracting a similar composition without conversion. Examples of vapors that are converted include hydrogen sulfide and ammonia.
