Exascale computing for Large-Scale Numerical Simulation requires a new technology for optical communication. VCSEL based transmitters run out of bandwidth at 56 Gbps PAM4, and the latency of PAM4 is incompatible with exascale computing. Other available technologies are excessively expensive, have high power consumption, are far from proven or they require temperature control.nbsp;Ournbsp;proposed ...

A system is proposed that can track the AE and RF energy dispersion that is created when a vehicle is impacted by a projectile at hyper velocity. This same device can measure the time of arrival of the wave front at transducers placed throughout the vehicle. Using the known velocity of the energy in the skin of the vehicle, the system can calculate the exact point of impact. Furthermore, Phase I t ...

This NASA SBIR Phase II proposal is in response to the need for Ultra-Stable Telescope Structures and is designed to evaluate ALLVAR Alloys for their potential as metering and support structures for optics that are critical to NASArsquo;s future missions. Telescopes used for astrophysics, exoplanet, and planetary studies require picometer stability over several minutes to hours. Building large sup ...

Two-phase flow fluids can offer more power to forced-convective heat transport, because such fluids utilize phase change to dramatically increase (or decrease) heat transport capabilities over single-phase flow convection.nbsp;nbsp;Unfortunately, two-phase flow systems are inherently unstable and can accordingly introduce significant management challenges in the reduced and variable acceleration f ...

Procedures play a large role in successfully testing and operating complex equipment. They provide step-by-step instructions for system check-out, experimental set-up, test plans, and responding to off-nominal situations. They also provide an electronic record of all test activities. As NASAnbsp; moves away from traditional paper procedures to more flexible electronic procedures, there is an oppor ...

Space energy storage systems are required to enable/enhance the capabilities of future planetary science missions. Venus aerial and surface missions pose challenges for energy storage systems where the temperature and pressure can be up to 460 Celsius and 92 bars, respectively. Therefore, high temperature batteries are significantly needed for future long duration Venus missions. Lynntech proposes ...

As Space systems become more complex and missionsrsquo; objectives become more challenging, with combination of advanced instrumentation, robotic systems and manned spacecraft, there is a clear need to rely on effective tools for performing trade evaluations in a cost-effective way. Currently there are model-based approaches used to develop system design. There is not a process for how to use mode ...

Building on previously successful rapid one step ldquo;bind and detectrdquo; or ldquo;lights onrdquo; DNA aptamer beacon assays for bone peptides and vitamin D (NASA Tech Briefs. MSC-24619-1/5091-1, September 2013, pg. 78), Nanohmics proposes to engineer optimized aptamer beacon assays for common components of bacterial and fungal cell walls based on 3D YASARA computer models of the aptamer-target ...

Windhover Labs proposes to create an Integrated Development Environment (IDE) to enable rapid software development of NASArsquo;s Core Flight System (CFS) projects by managing and auto generating flight software configuration and table data, integrating real time commands and telemetry, and providing an integrated scripting engine for testing. Open extensible, flight software combined with a highl ...

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...
