Collaborative 3D Training: From Astronauts to Automotive Techs

2004-07-19
2004-01-2593
As spaceflight hardware becomes increasingly complex, ever greater demands are placed on astronauts’ training capacity. In addition, astronauts are being asked to conduct unplanned operations with minimal or no training, and long duration operations preclude the ability to thoroughly train before flight on many operations. This trend will be more pronounced as we approach remote operations on the moon and Mars in the Exploration era. In response, Orbital Technologies Corporation has developed an interactive and collaborative 3D simulation training solution for payloads and International Space Station systems. This portable web-based training system provides flexible, efficient and effective pre-flight, real-time and operational training support. Unlike virtual reality systems, this next generation simulation can also be used for remote or just-in-time procedural training between ground-based experts and astronauts in space due to its low file size and collaboration capability.

Fluid Handling and Maintenance Experiment Capabilities

2001-07-09
2001-01-2179
The objective of the Fluid Handling and Maintenance Experiment (FHAME) is to research, test, and demonstrate liquid/gas phase control in fluid handling subsystems in microgravity. FHAME is currently being developed as a risk mitigation experiment for the upcoming verification and science investigations in plant growth systems, especially the Biomass Production System (BPS) and the Plant Research Unit (PRU). Because FHAME contains controlled fluid handling systems, a large suite of sensors, data acquisition, and visual observation capability, it is well suited for empirical research and testing of movement and to assessing the liquid/gas characteristics for a wide variety of applications. Its first application is to assess fluid priming and gas/liquid characteristics in a particulate bed. FHAME can play a major role in the development of future new nutrient delivery systems for plant growth application in addition to many fluid and gas/liquid empirical research investigations.

2001-01-2230
The Plant Research Unit development effort will provide a high-performance and highly versatile, controlled environment plant growth chamber for space-based variable gravity science and biotechnology investigations on the International Space Station. Temperature, humidity, atmospheric composition, lighting, and nutrient delivery are the critical parameters to control in an automated and reliable way. Access to plant material on-orbit and maintenance of the unit with minimal crew effort are other major requirements, as is a modular design allowing easy subsystem/technology change-outs so that science capability and maintainability are maximized. The Plant Research Unit (PRU) development program is based on the results of the Biomass Production System (BPS) and many other technical developments, and uses the BPS as a risk mitigation prototype for the PRU.

Research and Development, a First Consideration in Commercialization

2002-07-15
2002-01-2268
This paper summarizes the commercialization approach being used by Orbital Technologies Corporation and Planet Products Corporation. The approach begins with an overall strategy and is integral through several business, technology, and development decisions. Several stages exist in the development process, which begins with key go/no-go criteria and continues with more detailed assessment and analysis of technologies, markets, finance, and business/product models. The SBIR program and other seed funding opportunities are integral to individual product commercialization plans. ORBITEC has a very diverse technology heritage including environmental controls systems, combustion and materials, sensors/instrumentation, and advanced software systems. The commercialization approach is used to spin-off internally developed technologies as well as technologies from outside ORBITEC.

Science Accommodations in the Biomass Production System

The Biomass Production System (BPS) is a double middeck locker payload designed to fly on the Orbiter or Space Station. The BPS contains four plant growth chambers (PGCs) with independent control of temperature, humidity, lighting, CO2, and nutrient solution delivery, allowing for multiple experimental treatments. The BPS provides several features to support on-orbit science activities including the ability to downlink system and science data, video cameras with framegrab capability to collect images for recording plant development, access to plants to perform activities such as pollination or tissue sampling, and gas and fluid sampling ports for sampling of the plant environment. Other capabilities include the ability to conduct CO2 drawdowns, allowing photosynthetic measurements, and the ability to meter plant CO2 and water use. Several technology developments have been evaluated for possible implementation during future upgrades to enhance science capabilities.
