Space science is entering an era in which engineering innovation is no longer simply supporting scientific discovery—it is actively redefining what researchers can observe, measure and understand. That was the central message of a panel held in Florence, Italy, during the 46th COSPAR Assembly, where leading figures from aerospace companies, universities and the commercial space sector examined how new technologies are expanding the boundaries of scientific missions.
Moderated by Alison Nordt, director of Space Sciences and Instrumentation at Lockheed Martin Space’s Advanced Technology Center, the discussion brought together Marius Anger of Aalto University, Jon Arenberg of Northrop Grumman, Mayra Montrose of L3Harris, Giampiero Di Paolo of Thales Alenia Space Italia, Steve Squyres of Blue Origin and Eric Stallmer of Voyager. Their conversation focused on the increasingly close relationship between scientific ambition and systems engineering—the process of integrating hardware, software, operations and mission goals into a functioning space system.
One of the strongest themes was the rapid expansion of access to space. Smaller satellites, lower-cost launch services and commercially available spacecraft platforms are allowing universities, early-career researchers and smaller institutions to participate in missions that were once restricted to major national agencies. These opportunities provide students with practical experience in designing, building, launching and operating spacecraft, rather than limiting their education to laboratory studies or theoretical work.
The panellists argued that this shift requires stronger and more formal partnerships among universities, industry and government agencies. Scientific training alone is not sufficient for modern missions, they said. Researchers must also understand systems engineering, risk management, software development, testing, integration and mission operations. Early exposure to the full mission lifecycle could help create a workforce capable of managing increasingly complex projects while reducing the risks associated with inexperienced teams.
The panel also examined the consequences of what participants described as the democratisation of space. A growing number of universities, private companies, regional organisations and emerging space nations are now developing missions, instruments and services. This expanding community is creating new mission architectures and making scientific questions accessible that were previously considered too expensive or technically difficult to address. However, greater participation also introduces risks, particularly when funders, policymakers or the public do not fully understand the differences between a CubeSat, a flagship observatory, a commercial platform or a long-duration exploration mission.
Clear public communication was identified as an essential safeguard. Complex space projects often involve years of development, substantial financial investment and risks that cannot be eliminated entirely. The panellists pointed to the James Webb Space Telescope as an example of how sustained outreach can help the public understand both the scientific value and the engineering challenges of an ambitious mission. Communicating those realities is especially important as more private organisations enter a sector traditionally dominated by national space agencies.
Commercial capabilities are also transforming the technical landscape. Frequent launch opportunities are making it possible to send payloads of many different sizes into orbit, while new lunar transportation systems are being designed to deliver tonnes of equipment to the Moon. At the same time, commercial space stations in low Earth orbit could provide new locations for experiments in microgravity, Earth observation, technology testing and human spaceflight. Together, these developments could shorten the time between an instrument’s design and its deployment in space.
Technologies developed for major observatories are increasingly being adapted for smaller missions. The Habitable Worlds Observatory, a proposed space telescope intended to study potentially habitable planets and characterise their atmospheres, illustrates the scale of innovation required. Its development depends on technologies including extremely stable, low-vibration platforms, advanced ultraviolet optical coatings, picometre-level metrology and precision actuators, next-generation detectors, deformable micro-mirrors and high-contrast coronagraphs. A coronagraph blocks or suppresses the overwhelming light from a star, allowing scientists to search for the much fainter light reflected by an orbiting planet. Although these systems are being developed for a flagship observatory, several could eventually be miniaturised for smaller spacecraft.
Artificial intelligence and machine learning are expected to play a growing role in this transformation. Onboard algorithms can analyse data before it is transmitted to Earth, allowing spacecraft to identify transient events, prioritise observations or discard redundant information. This is particularly valuable when communication bandwidth is limited or when a spacecraft must respond autonomously. On the ground, machine-learning systems can compare large datasets from different instruments and missions, revealing correlations that might be difficult for researchers to detect manually. Such tools could accelerate the identification of patterns in space weather, planetary surfaces, astronomical surveys and atmospheric measurements.
The panel also highlighted photonics and photonic integrated circuits as technologies that could fundamentally change the design of scientific instruments. In some applications, researchers may replace conventional three-dimensional telescope architectures with compact two-dimensional systems capable of interferometric imaging, spectroscopy and polarimetry. Interferometry combines signals from multiple elements to obtain information about an object’s structure, while spectroscopy measures how light is distributed across different wavelengths and polarimetry analyses the orientation of light waves. Integrated photonic instruments could reduce size, mass, power consumption and cost, potentially enabling constellations of rapidly produced spacecraft for applications such as continuous space-weather monitoring. The panellists concluded that the combination of open collaboration, commercial access and advanced engineering could trigger a renaissance in space science, allowing more people to pursue ambitious questions about Earth, the Solar System and the wider universe.
