A data dictionary and additional information is located on the Data Resource Page. Files are refreshed monthly.
The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: NANOSONIC INC. Topic: T702
Through the STTR program, NanoSonic and Virginia Tech will create low-cost, reusable membranes that selectively capture and recycle nutrients (e.g., N, P, K) from urine in space. Urine is a readily available commodity in space that is rich in valuable nutrients for plant growth. Humans produce individually about 500 L of urine per year that contains ~7 g/L of nitrogen (N), ~1 g/L phosphorous (P) ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: ADVANCED SPACE LLC Topic: T1102
Distributed Spacecraft Missions (DSMs) such as constellations, formation-flying missions, and fractionated missions provide unique scientific and programmatic benefits. Distributed mission architectures allow for multipoint in-situ measurements, multi-angle viewpoints, and considerably improved understanding of the connections between separately measured phenomena and their time variations. DSMs a ...STTR Phase I 2017 National Aeronautics and Space Administration
Metal Digital Direct Manufacturing (MDDM) for Close-Out of Combustion Chambers and Nozzle FabricationsSBC: Keystone Synergistic Enterprises, LLC Topic: T1204
This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed. Process optimizations will be conducte ...STTR Phase II 2017 National Aeronautics and Space Administration
SBC: VOXTEL, INC. Topic: T901
To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...STTR Phase II 2016 National Aeronautics and Space Administration
SBC: Prime Photonics, LC Topic: T1201
Prime Photonics proposes to team with Dr. Duke of Virginia Tech to develop a multi-mode, enhanced piezoelectric acoustic emission sensing system to couple large damage events to local distribution of damage accommodation. Our system will be centered around an instrument designed to accept the output of a piezoelectric transducer sensitive to in-plane acoustic events. The signal processing path w ...STTR Phase II 2016 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T602
High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. Energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) may adversely affect not only beyond-Low-Earth-Orbit missions, but also aircraft avionics, communications, and airline crew/passenger health. It is cru ...STTR Phase II 2016 National Aeronautics and Space Administration
SBC: VOXTEL, INC. Topic: T901
One of the challenges facing missions to other planetary bodies including Earth's Moon, Mars, Venus, Titan, Europa; and proximity operations (including sampling and landing) on small bodies such as asteroids and comets' is the ability to provide accurate altimetry for descent, then assess safe landing sites by surveying the landscape. To address NASA's need for space-hardened planetary entry, desc ...STTR Phase I 2016 National Aeronautics and Space Administration
SBC: Advratech Topic: T1204
In this Phase I STTR project, pursuant to the Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) interests, the proposed collaborative effort between WSU and Advratech will represent the first AM optimization framework of its kind, constructed entirely from experimental sensor data collected in-situ. Rather than using in-process data to inform limited "phy ...STTR Phase I 2016 National Aeronautics and Space Administration
SBC: Tyvak Nano-Satellite Systems, Inc. Topic: T501
Tyvak, in collaboration with UCLA, proposes a novel approach to the challenge of creating a large reflector for Ka-band high data rate links. We propose to attach the primary reflector surface permanently to the surface of a 6U spacecraft and illuminate the reflector using a Cassegrain style subreflector with an illuminating antenna that is permanently mounted to the transmitter / receiver inside ...STTR Phase I 2016 National Aeronautics and Space Administration
SBC: Luna Innovations Incorporated Topic: T601
Luna is addressing NASA?s need to develop new multifunctional textiles for improved Environmental Protection Garments (EPG). Previous protective suits such as the Apollo era EPG or currently used Extravehicular Mobility Unit (EMU) provide thermal and micrometeoroid protection, but are intended only for short duration use. NASA plans for a future manned Mars mission will potentially require exten ...STTR Phase I 2016 National Aeronautics and Space Administration
