SPHEREx telescope and detectors

DescriptionSPHEREx telescope and detectors.jpg	English: The telescope is tilted to allow SPHEREx to map the entire sky. SPHEREx must carry out its observations without letting sunlight into the thermal system, which means the sun must always be more than 90 degrees off the central axis. If the telescope were pointed straight up, this constraint would leave two holes in the map coverage, located at the north and south ecliptic poles. By tipping the telescope slightly toward the sun, SPHEREx avoids these coverage holes while also preventing sunlight from entering the thermal system.
