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.
The new higher bandwidth from SpaceWire enables the JWST ISIM to support the mission's science instruments which employ 66 million detector pixels. This is the largest number of pixels ever used on a space telescope, and it will allow JWST to study more of the universe. Handling the large volume of data from these detectors presented a unique challenge for the JWST ICDH team. The development of this new network interface enables the JWST science instruments to realize their full scientific discovery potential, and will permit future NASA mission planners to consider use of more detectors with an even larger number of pixels to see even more of the universe.
