Vera C. Rubin Observatory
The Deepest, Widest View of Our Universe
The observatory, a project led by a consortium of more than 35 universities, research institutions, corporations and individuals, will provide an unprece- dented survey of the universe through panoramic imagery.
Once the observatory is fully operational, the telescope will survey the entire visible southern sky every few days for a decade. Over the course of the survey, the telescope’s 3,200 megapixel camera will amass about 800 panoramic images for each patch of the sky over 10 years, essentially creating “movies” of the universe. The observatory’s initial 10-year mission is named the Legacy Survey of Space and Time, or LSST.
The completed ground-based telescope will be located on Cerro Pachón in Chile and will provide scientists with the data needed to address today’s most compelling questions in astro-physics. Rubin Observatory has been designed as a public facility. Data will be available worldwide through the public engagement platform over the internet.
L3Harris was responsible for manufacturing the observatory’s secondary mirror and associated ground support equipment. At 3.5 meters in diameter, the 3,500-pound secondary mirror is L3Harris’ largest optic to date for a ground-based observatory, and was completed and shipped to the telescope’s location in South America in 2018. The secondary mirror is a solid meniscus design fabricated from ultra-low expansion glass.
L3Harris also manufactured the mirror’s cell assembly, which consists of the polished secondary mirror, mirror support system, mirror cell electronics and sensors, thermal control system and the mirror control system.
