The Role of the New Rubin Observatory on Earth in Advancing the Future of Asteroid Space Exploration

The Vera C. Rubin Observatory, currently under construction, is set to provide unprecedented insight into the cosmos when it begins operation in 2025. The observatory will be capable of detecting millions of new asteroids, comets, and other celestial bodies, as well as tracking them as they move through our solar system. This advanced capability is expected to revolutionize space exploration and research.

The solar system is home to billions of small rocky bodies and icy objects, many of which were formed around 4.5 billion years ago, during the formation of Earth and other planets. NASA’s OSIRIS-REx, Lucy, and Psyche missions have been studying these primordial objects, collecting images and samples informed by data from observatories worldwide. The Rubin Observatory is expected to significantly contribute to this body of knowledge.

Once operational, the Rubin Observatory will conduct a 10-year Legacy Survey of Space and Time (LSST), monitoring solar system bodies and cosmic objects beyond the limits of our solar system and the Milky Way galaxy. Using an 8.4-meter fast-moving telescope and the world’s largest digital camera, the observatory is expected to increase our catalog of known solar system objects by at least five times over the next decade.

Scientists anticipate that the Rubin Observatory will not only detect a multitude of new solar system objects but also provide more information about the broader “spacescape” of the solar system. This could reveal regions containing unique objects that could become targets for future space missions. Moreover, the observatory will be able to alert operators to changes in the night sky within 60 seconds of spotting them, which could facilitate quick planning and deployment of missions towards rapidly moving objects of interest.

This rapid detection capability could also provide scientists with an early warning of an interstellar object like Oumuamua passing through our solar system, allowing for in situ study before the object leaves our reach. This combination of capabilities is unique to the Rubin Observatory and represents a significant advancement in our capacity for space exploration and research.

One project already planning to utilize Rubin data is the JAXA/European Space Agency Comet Interceptor mission, set to launch in 2029. This mission will wait for the sighting of a visitable, long-period solar system comet or interstellar object as it passes in front of the sun before being deployed for investigation. Other missions, such as NASA’s asteroid-hopping spacecraft Lucy, could also benefit from Rubin’s observations.

Overall, the Vera C. Rubin Observatory represents a significant leap forward in our understanding of the cosmos. Its advanced capabilities will provide unprecedented insight into our solar system and beyond, paving the way for new discoveries and advancements in space exploration.
