Nikon is expanding its long-standing relationship with NASA by sending a specialized live cell observation system to the International Space Station (ISS) to study the biological impacts of microgravity. The project, developed in collaboration between Nikon Corporation and its U.S. Subsidiary, Nikon Instruments Inc. (NII), aims to advance drug discovery and life sciences by observing how living cells and tissues behave outside the influence of Earth’s gravity.
The equipment is scheduled to launch from Cape Canaveral Space Force Station in Florida on NASA‘s Northrop Grumman Commercial Resupply Services (CRS) 24 mission, currently set for April 9, 2026. Once aboard the station, the system will undergo foundational operational verification to ensure it can effectively culture, maintain, and monitor biological samples in a space environment.
This initiative is supported by the Center for the Advancement of Science in Space (CASIS), which manages the ISS National Laboratory. By utilizing a specialized microscope system, researchers hope to unlock new insights into the mechanisms of aging and the progression of various diseases, providing data that is nearly impossible to replicate in terrestrial laboratories.
The NEMO System: Bridging Microgravity and Microscopy
At the heart of this mission is the Nikon Experimentation Microscope in Orbit (NEMO). This is not a standalone device but a sophisticated integration of two distinct technologies designed to keep biological samples alive and visible over long durations. The NEMO system pairs Nikon’s high-precision live cell observation hardware with a specialized cell culture incubator and automated media perfusion system developed by BioServe Space Technologies, based in Boulder, Colorado.
The synergy between these two components is critical. While BioServe’s system ensures the cells remain in an optimal environment—mimicking the conditions they would find inside a living organism—Nikon’s microscopy hardware provides the visual data. Together, they allow for the use of Microphysiological Systems (MPS), which are 3D culture systems that recreate the complex environments of human organs and tissues.
For those unfamiliar with the technicality, these “organs-on-a-chip” or 3D cultures allow scientists to test how pharmaceuticals interact with human tissue in real-time. In the limited space of an ISS experiment module, the ability to conduct long-term visual analysis of cell behavior is a significant leap forward for pharmaceutical research and biotechnology.
A Legacy of Optical Precision in Space
Nikon’s entry into the ISS laboratory is the latest chapter in a partnership with NASA that dates back to the Apollo 15 mission in 1971. Over five decades, the company’s lenses and cameras have become staples of space exploration. Most recently, the Nikon Z9, the company’s flagship mirrorless camera, has been deployed on the ISS to capture high-resolution imagery.
The transition from capturing landscapes and astronaut activity to microscopic biological analysis is a natural evolution of this reliability. In 2021, Nikon was selected for an ISS development support project for private companies, funded by U.S. Government grants via CASIS. This preliminary work paved the way for the current contract between NASA and Nikon Instruments Inc., with NII handling project management and both entities collaborating on the system’s technical development.

Why Microgravity Matters for Drug Discovery
The primary driver behind this research is the unique environment of the ISS. On Earth, gravity influences how cells grow, how fluids move, and how tissues organize themselves. By removing this variable, scientists can observe “pure” biological responses. This is particularly valuable for understanding the causes of aging and the behavior of diseased tissues, as the absence of gravity can sometimes simulate certain pathological conditions or allow for the growth of more complex 3D tissue structures that would collapse under their own weight on Earth.
Global life science companies and pharmaceutical firms are increasingly interested in these findings. The ability to observe how a drug candidate affects a 3D tissue sample in microgravity could accelerate the development of more effective treatments and reduce the reliance on traditional animal testing by providing more accurate human-mimicking models.
Beyond drug discovery, the research is essential for the future of human spaceflight. As NASA and other agencies look toward long-term missions to the Moon and Mars, understanding how microgravity affects human biological tissues over time is a prerequisite for ensuring astronaut health and safety during multi-year journeys.
Operational Constraints and Next Steps
Operating a high-precision microscope in orbit is not without challenges. The system must be compact enough to fit within the constrained environment of the ISS experiment modules and robust enough to withstand the vibrations of launch. The automated media perfusion system provided by BioServe must operate flawlessly to ensure the cells do not perish during the observation period.
The upcoming CRS-24 mission will serve as the critical “foundational operational verification” phase. So the primary goal is to prove that the NEMO system can function as intended in the actual environment of the station before moving into more complex, long-term biological experiments.

The next confirmed milestone for this project is the launch of the Northrop Grumman CRS-24 mission in April 2026, which will move the live cell observation system from the testing phase to active orbital verification. We will continue to monitor the progress of the NEMO system as it prepares for flight.
