nbsp;NASA is developing an Exploration Portable Life Support Subsystem (xPLSS) for next-generation Exploration Extra Vehicular Mobility Units (xEMU) planned to replace existing space suits. NASA has identified technology gaps in current xPLSS due to the amine swing-bed system not being design for the partial atmosphere of Mars. To solve this, NASA is requesting the development of a robust ldquo;Bo ...

Aerosol extinction measurements are crucial to understanding the effects of atmospheric particles on ozone depletion (stratosphere), radiation (stratosphere and troposphere), visibility (troposphere) and public health (boundary layer).nbsp; Despite the acute need, no existing instrument can measure direct, in situ aerosol extinction profiles from the ground to the mid-stratosphere.nbsp; Satellite- ...

nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; Enrsquo;Urga Inc. will evaluate the feasibility of utilizing a modular sensor suite as general purpose combustion diagnostic for rocket propulsion systems. nbsp;The two key issues that will be addressed during the Phase I research work are: (1) the feasibility of configuring a modular tomographic sensor suite that can be used measure path int ...

New processor architectures, such as ARM and RISC-V have greatly improved SWAP-C for the computational power that they provide, especially when compared to the systems that are currently relied on for spacecraft requiring robust computer hardware. ARM has seen wide adoption in the consumer space due to its low cost and efficiency and RISC-V has the potential to enable the introduction of custom ch ...

In an effort to address current technical gaps in thermal management systems for small spacecraft, Roccor proposes to raise the Technology Readiness Level (TRL) of FlexCool, a promising extremely thin (lt; 1 mm), easily bent, high heat flux, heat pipe. The heat pipe proposed for this effort will undergo several environmental tests to qualify its use for flight and a microgravity test. Roccor has b ...

There are a number challenges to small UAS operations in the NAS. One of the most critical of these is access to microscale, hyperlocal weather estimates and predictions.Small UAS weigh less than 55 lbs have the risk of losing control in presence of light winds and gusts. The risk is amplified in urban areas due to presence of tall building and other man made objects. The phenomenon of urban canyo ...

This includes beyond Low Earth Orbit (LEO) space exploration requiring innovative lightweight and multifunctional structure concepts. Conformal designs offer enabling mass and volume efficiencies and, multifunctional potential. Steelhead Composites ...

The Lunar Flow Battery (LFB) is a scalable, long-duration energy storage solution featuring minimum capacity fade over many cycles that uses electrolytes derived from lunar regolith to minimize launch mass. The LFB operates by storing two separate solutions of redox-active species which are pumped past the cathode and anode respectively to produce a current. By pumping the redox-active fluids acro ...

Large solar arrays required for next generation space exploration require new technology. The performance goals required for these missions are not attainable using OTS technology. The Compact Telescoping Array (CTA) is under development to meet these needs. One important component within the CTA architecture (and any H-configuration solar array) is the Telescoping Truss Mast (TTM). Opterus, worki ...

Detection and identification of a broad band of chemical species is a hallmark of mass spectrometry. The specific, accurate mass of ions formed in the ionization source and measured in the mass analyzer gives a mechanism for identification of the analyte. Characteristic fragmentation of the molecular species provides additional information that enhances specificity. Thus, mass spectrometry is cons ...
