Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a wide-bandgap GaP-based space solar cell capable of efficient operation at temperatures above 300oC. Efficiency enhancement will be achieved by the introduction of InGaP quantum wells within the active region of the wide-gap base material. The introduction of these nanoscale features ...

Opterus Research and Development, Inc. proposes to develop and validate multi-scale thin-ply High Strain Composites (HSCs) constitutive modeling tools for incorporation into commercial finite element analysis codes. The constitutive models will capture the time-temperature-load-deformation viscoelastic characteristics common to HSCs as well as the yielding or permanent deformation associated with ...

Regenerative space life support will undoubtedly require food production, to recover nutrients and close the carbon loop in a spacecraft habitat. Aquatic plants have enormous potential for edible biomass production but have been little studied as potential food crops for space applications. The proposed μG-LilyPond™ is an autonomous environmentally controlled floating plant cultivation system ...

Current state of the art inertial measurement units (IMUs) co-locate a set of accelerometers and gyroscopes into a single package. CU Aerospace (CUA), in partnership with the University of Illinois, propose to develop a scalable and distributed IMU for space robotics and CubeSat applications. The user can choose to include an arbitrary number of inertial sensors beyond the minimal number of sensor ...

This program will develop a communication-less solution to decentralized control and task coordination for multi-agent systems (MAS). Reducing the operational burden of MAS swarms on human operators will greatly improve the capability of spacecraft constellations and distant planetary explorations. The proposed solution would guide the MAS towards a cost minimized set of actions by performing grad ...

We propose the development of a user-friendly software tool for estimating the electric field distributions within spacecraft enclosures based on the Power Balance (PwB) method and enhanced by a database of experimentally determined Absorption Cross-Sections (ACS) of common equipment, components and cables.The software will be built around an already developed PwB solver that determines the statis ...

Protection against the buildup of CO2 in spacecraft is of crucial importance to astronaut health. Currently, several methods are used to remove CO2 from spacecraft including amine scrubbers, lithium hydroxide canisters, and adsorbent-based carbon dioxide removal assemblies (CDRAs). Each scrubbing method has individual benefits and drawbacks: amine scrubbers have no particulate release but require ...

Computational tools that accurately predict the performance of electric propulsion devices are highly desirable by NASA and the broader electric propulsion community. Large investments in running the long duration test programs (> 20 kHrs) at NASA GRC can be reduced with computer models and allow more focus on exploring the NEXT ion thruster design for future space missions. The current state of e ...

Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a space solar cell having record efficiency exceeding 40% (AM0) by the introduction of nanowires within the active region of the current limiting sub-cell. The introduction of these nanoscale features will enable realization of an intermediate band solar cell (IBSC), while simultaneous ...

The MarsOasis™ cultivation system is a versatile, autonomous, environmentally controlled growth chamber for food provision on the Martian surface. MarsOasis™ integrates a wealth of prior research and Mars growth chamber concepts into a complete system design and operational prototype. MarsOasis™ includes several innovative features relative to the state of the art space growth chambers. I ...
