For decades, scientists believed Vesta, one of the largest objects in our solar system’s asteroid belt, wasn’t just an asteroid and eventually concluded it was more like a planet with a crust, mantle and core. Now, Michigan State University has contributed to research that flips this notion on its head.
A team led by the NASA Jet Propulsion Lab, or JPL, authored a paper, published in Nature Astronomy, that reveals Vesta doesn’t have a core. These findings startled researchers who, until that point, assumed Vesta was a protoplanet that never grew to a full planet.
Scientists at the University of Leicester and NASA’s Glenn Research Center have combined cutting edge radioisotope power system technology with high efficiency power convertor technology
The successful test results demonstrate robustness and reliability for potential future spaceflight missions, and a pathway for applications in space
The Space Nuclear Power team based at Space Park Leicester travelled to NASA Glenn in January 2025 to support the project
The SETI Institute and the Maldives Space Research Organisation (MSRO) will collaborate on astronomy research, space science education and public outreach. This initiative, established through a Memorandum of Understanding (MOU), provides a framework for projects that combine cutting-edge scientific research with the rich cultural heritage of Maldivian celestial navigation.
The collaboration began during the 2024 Space for Island Nations Conference (SIN2024), where the SETI Institute first learned about MSRO’s efforts to engage students and the public in astronomy. MSRO recently acquired a Unistellar telescope to provide students and tourists with hands-on experience in astronomy. Additionally, they published a cultural star map highlighting significant constellations and patterns based on ancestral Maldivian navigation traditions.
“We saw the incredible work MSRO was doing at SIN2024, inspiring this exciting collaboration,” said Dr. Franck Marchis, Director of Citizen Science at the SETI Institute and Chief Science Officer at Unistellar. “The Maldives, with its unique location and cultural connection to the stars, is an ideal place to develop new astronomy initiatives. We look forward to working with MSRO to bring science and traditional Maldivian wisdom together."
