NASA's James Webb Space Telescope will use a new advanced technology network interface called "SpaceWire" that enables the components on the telescope to work more efficiently and more reliably with each other.
SpaceWire is a standard for high-speed communication links between satellite components. Originally developed by the European Space Agency, SpaceWire has been adopted and improved by a team at the NASA Goddard Space Flight Center in Greenbelt, Md. The James Webb Space Telescope (JWST) Integrated Science Instrument Module (ISIM) and Command and Data Handling (ICDH) engineering team has developed a small and very low power microchip that sends and receives SpaceWire signals at speeds of over 200 mega-bits per second.
As a result of this JWST technology development, other missions are considering SpaceWire include the Lunar Reconnaissance Orbiter and the Geostationary Operational Environmental Satellite-R (GOES-R).
The benefit to other missions from using SpaceWire is a lower cost for development, a reduction of development time, better reliability, and an increase in the amount of scientific work that can be achieved within a limited budget.
