During Artemis 2’s far-side lunar flyby, astronauts observed multiple micrometeorite impacts on the Moon, prompting audible cheers from NASA’s Science Evaluation Room; scientists were surprised by the frequency of impacts and will study the flashes to better understand the lunar environment, noting a solar eclipse during closest approach and marking the first crewed lunar-spaceflight since Apollo 17.
Scientists are scouring the roofs of English cathedrals, such as Canterbury Cathedral, for cosmic dust particles known as micrometeorites. These tiny particles, which likely originate from comets and asteroids, provide valuable insights into the chemistry of asteroids and meteorites, as well as Earth's history and changes over time. Researchers are using vacuum cleaners to collect thousands of dust particles in the hopes of finding minuscule cosmic spherols, and are also exploring the potential influence of cosmic dust on Earth's chemistry and early prebiotic chemistry. The abundance of urban micrometeorites is opening up planetary science to a wider audience and providing a snapshot of the different processes and bodies in outer space.
Scientists from the University of Kent are conducting a search for cosmic dust on the roof of Canterbury Cathedral in order to gather information about the origins of the solar system. The cathedral's inaccessible roof provides an undisturbed site for collecting micrometeorites, which are dust-sized particles that have made it through the Earth's atmosphere. This new approach of exploring UK cathedrals, due to their age and detailed records, offers an alternative to remote locations like Antarctica or ocean floors where cosmic dust has been previously searched for. The project will extend to other cathedrals, starting with Rochester Cathedral in Kent.
