The Bioastronautical Systems Development Company (BSDC) proposes to develop habitat technologies for conducting long-term commercial research with mice in microgravity. Our research addresses solicitation section B4.02 Space Commercialization for the design/development of microgravity payloads for space station applications that lead to commercial products or services. In partnership with BioServe ...

In November 1998 a network of seismic stations was deployed by S. Anandakrishnan (now at Penn State) and others in West Antarctica. These autonomous stations returned state-of-health data via satellite, and stored high-volume instrument data for later retrieval. The satellite links demonstrated a novel and sophisticated application of technology to the problem of retrieving in situ data from harsh ...

TDA Research, Inc. proposes to develop a biodegradable food packaging material that will address the issues of extended-life food storage and waste disposal in space. On long-term space missions, on board the International Space Station, or on future lunar or planetary facilities, a biodegradable food packaging plastic could be disposed of in composting environments that support agricultural produ ...

The Cockpit System Situational Awareness Modeling Tool will use the principles of discrete event simulation to predict pilot situational awareness (SA). The human performance modeling environment of IMPRINT combined with the cognitive modeling tool ACT-R will provide a powerful tool for the designers of cockpit systems. IMPRINT can already be used to predict pilot workload and assess the effects o ...

We will develop a compact external cavity stabilization system, which will employ independent electro-optic control over the optical path length of the cavity and a wavelength-selective element. The system should be able to cover a 30 nm range and give mode-hop-free tuning over 20 nm intervals. The design of the feedback system will be compatible with any commercially available laser diode from 63 ...

Technology Applications, Inc. (TAI) is proposing to demonstrate feasibility of cryogenic propellant insulation technologies that improve the thermal performance, operational efficiencies, durability, reliability, and safety of these systems in earth, space, and extraterrestrial environments. The new technology, which employs microspheres as the insulating medium, provides for robust, low-maintenan ...

This Small Business Innovation Research Phase 1 project proposes to develop a femtosecond laser system optimized for optical clocks and other precision metrology applications. In principle, atomic optical transitions have the potential to provide radically higher-accuracy timekeeping, because of the very high frequency of an optical transition. The problem of counting, or down-counting, the oscill ...

We propose to compare alternative architectures for phase noise measurement by directly sampling the RF waveform. Out of band modulation and cross correlation will reduce noise. The capabilities of each architecture will be determined using analysis and simulation. The results will be used to determine the feasibility of developing a commercially useful measurement instrument. If the results are p ...

Using existing technology, high-accuracy precision 2-axis fine-steering mirror (FSM) applications are limited to position sensors with 0.4 to 1.0 urad resolution. A number of applications, such as JPL?s optical communication programs require 0.1 urad resolution. Three recently developed commercial off-the-shelf (COTS) sensors have inherently better resolution, but have not been proven in FSM appli ...

Accurate Automation Corporation proposes a three-pronged effort to build on the Phase I program to develop technologies in support of the NASA Hyper-X program and the X-43 series of research vehicles (X-43A, X-43B, and X-43C). The data and technologies developed under the proposed Phase II program will also support the development and testing of future hypersonic vehicles and reusable launch vehic ...
