Rubin Observatory Starts 10-Year Sky Survey With 3,200-Megapixel Camera

Q: With a giant asteroid flyby in 2029, will the Rubin Observatory's new sky map be our key to planetary survival?

No. The Rubin Observatory will strengthen planetary defense, but it is not the key to surviving the 2029 Apophis flyby because Apophis is not expected to hit Earth. Apophis, about 370 meters wide, will make a very close pass on April 13, 2029, closer than geostationary satellites. Early impact fears after its 2004 discovery were eliminated by later observations and radar tracking. Scientists now treat the flyby as a rare research opportunity, not an impact emergency. Rubin’s importance is broader and long-term. Its 10-year Legacy Survey of Space and Time will scan the southern sky nightly with a 3,200-megapixel camera, detecting millions of changes and vastly expanding the catalog of asteroids and other moving objects. Researchers expect it to identify 80% to 90% of potentially hazardous asteroids larger than 140 meters, a major gain for early warning. Its value is not just finding more objects. Rubin is also expected to improve the accuracy of asteroid positions and orbits by correcting biases in existing sky catalogs, which directly matters for collision-probability calculations years or decades ahead. That makes future hazard assessments more reliable. Planetary defense, however, depends on a wider system: ground surveys, international warning networks, deflection planning, and dedicated missions such as NASA’s NEO Surveyor and the proven DART approach. Rubin will be one of the most powerful new tools in that system, but not the deciding factor for Apophis in 2029.

June 30 marked the start of Rubin Observatory’s Legacy Survey of Space and Time, a decade-long campaign to build an ultrawide time-lapse record of the universe.
Every 40 seconds, the Chile observatory will capture a new image and scan the entire southern sky every few nights, revisiting each point about 800 times over 10 years.
About 1,000 images a night will generate roughly 10 terabytes of data daily from the world’s largest digital camera, designed to track changes, transient events and moving objects.
First test images last summer already revealed millions of galaxies and stars plus thousands of previously unseen asteroids, underscoring the survey’s potential to probe dark matter, dark energy and cosmic expansion.

Overview

The Vera C. Rubin Observatory began its Legacy Survey of Space and Time (LSST) on June 30, 2026, marking the start of a new era in cosmic discovery. Even before the official launch, the observatory showcased its power by identifying over 11,000 new asteroids, 33 near-Earth objects, and 380 trans-Neptunian objects. These early results highlight the observatory’s efficiency and hint at the vast data and insights the full LSST will provide. Designed to map the universe with unmatched detail, the LSST promises to revolutionize our understanding of the cosmos over the next decade.
