Deep Synoptic Array Clears Final Design for 1,650 Dishes as 2029 Nevada Build Starts

Summary
Caltech’s Deep Synoptic Array has reached its final design milestone and is moving into construction in Nevada, with the 1,650-dish radio observatory targeted for completion by 2029.
1,650 antennas spread across more than 120 square miles will process signals in real time instead of storing raw feeds that would rival all U.S. internet traffic, enabling much faster sky surveys.
100 times faster survey speed is expected to let the array localize tens of thousands of fast radio bursts and track pulsars closely enough to test suspected gravitational-wave signals.
Schmidt Sciences is funding the project, which pairs NVIDIA Vera Rubin GPUs with low-cost modified cake pans for dish components in a design backers say could reshape radio astronomy.

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.
