Vera C. Rubin Observatory Launched Its 10-Year Sky Survey on June 30, Generating 10 Terabytes of Data Per Night

The biggest sky survey in history is now underway

The Vera C. Rubin Observatory, perched in the Atacama Desert of Chile, kicked off its Legacy Survey of Space and Time (LSST) on June 30, 2026, according to a press release from the National Science Foundation and the U.S. Department of Energy.

The observatory houses the largest digital camera ever built: 3,200 megapixels. It will capture a new image roughly every 40 seconds, revisit every point in the southern sky every few nights, and accumulate approximately ten terabytes of data per night. Over its ten-year run, each patch of sky will be photographed around 800 times, creating a time-lapse record detailed enough to catch transient events like supernovae, near-Earth asteroids, and shifts in distant galaxies.

"Today, we begin filming the greatest cosmic movie ever made," Brian Stone of the National Science Foundation said in the announcement.

The science targets are ambitious. Darío Gil, Under Secretary for Science at the U.S. Department of Energy, said the survey "will redefine modern cosmology and astrophysics" by probing dark energy and dark matter — two phenomena that remain poorly understood. Gil added that the observatory is "not just observing the stars" but "striving to grasp the fundamental laws that govern our existence."

The observatory completed a test run last summer, producing detailed views of millions of galaxies and stars along with thousands of previously uncatalogued asteroids. That dry run confirmed the hardware performs at spec. The June 30 start date marks the transition from testing to the full, decade-long scientific campaign.

The project has been more than 20 years in development, surviving multiple budget cycles, changes in federal science leadership, and the kind of institutional friction that kills long-horizon government projects. Reaching operational status represents a milestone for U.S.-funded basic science.

The spending question worth asking

Projects of this scale, funded by NSF and DOE over decades, represent billions in taxpayer investment with payoffs measured in generations. Supporters argue that basic science spending — the kind that produced GPS, the internet, and MRI technology — consistently delivers returns that dwarf the upfront cost. Critics reasonably ask whether the federal government is the right vehicle, and whether the timeline discipline on multi-decade projects is adequate. Those are legitimate questions about government science funding that don't have a clean partisan answer. What's demonstrable is that Rubin delivered functional hardware and began its operational mission on schedule.

Cyborg cockroaches with diving suits, for actual rescue operations

On the stranger end of this week's science news: researchers from Nanyang Technological University Singapore and Waseda University announced a miniature diving suit that allows cyborg cockroaches to operate underwater for hours at a time.

The subjects are living Madagascar hissing cockroaches fitted with electronic controllers. The diving apparatus consists of an oxygen-generation tank, a flexible shell, and four silicone supply tubes. A flooded environment previously rendered these insects inoperable; the suit changes that. In tests, the cyborg robots were able to swim underwater for up to three hours with this setup, according to a paper published in Nature Communications.

The practical case is real. Cyborg insects can access spaces inaccessible to humans, dogs, or conventional robots — collapsed building voids, narrow pipe systems, rubble pockets with water infiltration. According to the research team, cyborg roaches were deployed in an actual field operation this spring to assist with search and rescue after a devastating earthquake in Myanmar. That deployment represents the first known field use of cyborg insects in disaster response.

The waterproofed version would extend that capability to flood disasters or submerged structures, a common scenario in earthquake aftermath when water mains rupture or coastal structures collapse.

The unresolved question for Rubin

Over ten years, the LSST is expected to catalog vast numbers of astronomical objects and generate data volumes that no single institution can process manually. The NSF and DOE have both committed to the survey infrastructure, but the data pipeline — how terabytes of nightly observations get analyzed, shared with the global research community, and turned into publishable science — remains the less-publicized challenge. Whether the computational and institutional frameworks can keep pace with the hardware's output is the practical question the next few years will answer.
