The largest camera ever built for astrophysics (3200-megapixels, >3000 kg) was installed this week at the Rubin Observatory at Cerro Pachón in Chile.

The Legacy Survey of Space and Time (LSST) camera, the final major component of the Rubin Observatory's Simonyi Survey Telescope, was transported to the summit in May 2024.

After a few more months of testing, first light is expected around 4 Jul 2025.

NSF–DOE Vera C. Rubin Observatory Installs LSST Camera on Telescope

Using the largest digital camera in the world, Rubin Observatory will soon be ready to capture more data than any other observatory in history

^{www.noirlab.edu}

The Rubin Observatory generates an astronomical amount of data every night which is stored and processed in 3 main data centers located in the U.S., the U.K. and France.

Image size: 6.4 GB compressed
Images per night: 2,000+
Data per night: 16 TB
Raw data over 10 years: 50 PB
Processed data over 10 years: 500 PB
Image transfer time (from Chile to SLAC in CA): 7 seconds
Transfer speed: ~7.3 Gbps
Alerts per night: Up to 10 million

Images are transferred from the Rubin Observatory using "direct writes via the S3 API to an object store" at the US Data Facility at SLAC in CA and distributed to the UK and France sites.

Given the high bandwidth-delay product of the links between sites (~8 Gbps per image transfer * ~165 ms round trip time RTT = ~165 MB), transfers are done using specialized connection pooling/keep-alive code and TCP tuning (e.g., initial and max cwnd size, congestion control, ..).
