Deep Space Design Considerations

The linchpin technology in a deep space telescope is the ability to efficiently convert analog image sensor data into digital data in order to beam home high-resolution images of astronomical objects. The analog-to-digital converters (ADC) must perform flawlessly once deployed, because it is not feasible to drive out 1 million miles into space to fix any problems. The next-generation success... » read more

Analog-To-Digital Conversion Is Key For Deep Space Exploration With The James Webb Space Telescope

Reflect back to your last design project. Did it have leading-edge requirements that seemed impossible at the time to fulfill? Now think about a design that needs to live in the harsh environment of space. A device that has to sip power and function flawlessly for over a decade because there is no opportunity to service it if anything goes wrong. That is the set of requirements that faced Dr. L... » read more

Manufacturing Bits: Dec. 10

Space Telescopes The James Webb Space Telescope, the follow-on mission to the Hubble Space Telescope, is a large, infrared-optimized space telescope. Slated for a launch date of 2018, Webb will find the first galaxies that were formed in the early Universe. Webb is a collaboration between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA). Webb’s measurements will ... » read more
