Journey of Astronomy’s Largest Camera
How scientists shipped astronomy's largest camera from California to Chile
After two decades of meticulous work, the camera destined for the
Vera C. Rubin Observatory has finally reached its home atop the Cerro Pachón
mountain in Chile. This remarkable camera is the heart of the Rubin
Observatory's Simonyi Survey Telescope, and it's no ordinary piece of
equipment—it's the largest camera ever built for astronomy. Weighing a
staggering 6,600 pounds (3 metric tons) and spanning over five feet (1.5
meters) across, the camera's safe transport from the SLAC National Accelerator
Laboratory in California to the observatory's location was a monumental task.
To minimize risk to the $168-million eyepiece, scientists and
engineers conducted a "full dress rehearsal" in 2021. They shipped an
analog of the camera's mass to Chile, equipped with data loggers to document
the conditions it would encounter during the journey. On May 14, 2024, the
actual camera embarked on a 10-hour flight from San Francisco to Chile aboard a
Boeing 747 cargo plane. It then travelled by road, covering 21.7 miles (35 kilometres)
up a winding dirt road to reach the summit of Cerro Pachón, sitting more than
8,900 feet (2,713 meters) above sea level.
This achievement represents a significant milestone in our quest
to explore the cosmos, and the camera's installation promises groundbreaking
discoveries in the field of astronomy.
