Caltech Starts 1,650-Dish Nevada Radio Array After Final Design Review

Summary
Caltech has begun construction of the 1,650-dish Deep Synoptic Array in a remote Nevada valley after the project cleared its final design review with Schmidt Sciences.
By 2029, the array is slated to start science operations and scan the radio sky 100 times faster than existing telescopes by linking thousands of small dishes across a wide desert site.
A real-time supercomputer is central to the design, turning incoming signals into images immediately and avoiding roughly 100 exabytes of storage—about 5 million hard drives, Caltech said.
Caltech says the telescope could match the roughly 20 million radio sources found by all radio telescopes to date in its first day and reach about 1 billion by the end of its first survey.
The project will release science-ready images with no proprietary delay, positioning the DSA to complement optical surveys such as the Vera C. Rubin Observatory and Zwicky Transient Facility.

The Deep Synoptic Array: Revolutionizing Radio Astronomy with 1 Billion New Discoveries and Open Data
Overview
The Deep Synoptic Array (DSA), developed by Caltech, marks a groundbreaking advancement in radio astronomy by introducing advanced design and processing capabilities. Set to launch in June 2026, the DSA is poised to transform large-scale sky surveys by efficiently handling the massive data generated by modern radio observations. Without such technology, storing 100 exabytes of data would require an unmanageable infrastructure of millions of hard drives and enormous costs. The DSA's innovative approach overcomes these challenges, making ambitious astronomical projects possible and opening a new era of discovery in understanding the universe.
