NASA yesterday released the first full set of full-color images of the deep space from the James Webb Space Telescope (JWST).
According to the report, JWST is estimated to cost up to $10 billion in total. It was lifted off by an Ariane 5 rocket on Dec. 25 last year. Once in space, JWST will need to travel for a period of time before entering its intended orbit, and will remain in orbit thereafter. The orbit is located at the second Lagrangian point, where gravity is relatively stable, so it can maintain a constant position relative to neighboring objects, eliminating the need for frequent position corrections and allowing for more stable observations.
According to a paper published by the Space Telescope Science Institute, JWST’s overall event-driven architecture provides greater flexibility in operating the telescope and significantly simplifies the underlying system. In addition, the autonomy of the event-driven system provides spacecraft and science instrument commands based on telemetry responses. In the event of a malfunction, the telescope can continue with the portion of the science observing program that is unaffected by the event, thus ensuring maximum efficiency of the observatory.
