 Studying phenomena in space enables us to make the invisible visible, which is exactly what NASA's light microscopy module accomplished during its time aboard the International Space Station. Using this unique microscope, scientists and researchers were able to take advantage of the microgravity conditions found aboard the space station. In these conditions, they were able to perform three-dimensional experiments that would have been two-dimensional experiments on Earth or simply not possible. From 2009 to 2021, researchers from six countries and 27 universities and research partners spent thousands of hours employing the remarkable power of this state-of-the-art, light-imaging confocal microscope facility. They studied a variety of physical and biological phenomena, such as how matter is organized, can be made to self-assemble, and how it behaves on the microscopic level. By helping us understand these processes, LMM contributed greatly to scientific discovery, benefiting people on Earth and future space missions. Impacts include innovations in consumer products, better understanding earthquake phenomena, advancements towards the next generation of highly efficient quantum dot-sensitized solar cells, improvements in biomedical device technology, and potential innovations in construction materials for use on Earth, the Moon, and Mars. LMM made a remarkable impact during its years of service. Now, after 12 years of advancing science for all humankind, it's time to say farewell to this microscope that helped change the world. Thank you, LMM, for paving the way to the future. You all miss it.
