The overall goal for this technology development effort is to achieve 100 percent cost savings as compared with traditional cryogenically cooled infrared sensors. The weight and volume savings allow for more compact instruments -- an important consideration for a spacecraft's payload size and cost. This state-of-the-art technology also will have spinoff applications for commercial instrument manufacturers.
Another technology Woven Heat Shield
Seeking to radically change the way heat shields protect spacecraft during atmospheric entry, NASA's Ames Research Center at Moffett Field, Calif., is developing the Woven Thermal Protection System. The project is a revolutionary approach to thermal protection system design and manufacturing for extreme environments. Ames is the lead center for the project, partnering with NASA's Langley Research Center in Hampton, Va.
Partnering with the U.S. textile industry, NASA is employing an advanced, three-dimensional weaving approach in the design and manufacture of thermal protection systems. Today, lightweight aircraft parts are being manufactured using similar weaving technologies. This will be expanded to include spacecraft heatshield applications. The system will enhance performance using advanced design tools with cost savings from a shortened product development and testing cycle.
"Woven TPS has the potential to significantly impact future NASA missions by changing heat shield development from a challenge to be overcome into a mission-enabling component," said NASA Langley's Ethiraj Venkatapathy, principal investigator of the project. "By delivering improved heat shield performance and affordability, this technology will impact all future exploration missions, from the robotic science missions to Mars, Venus and Saturn to the next generation of human missions."
