International Space Station Reaches 25 Years of Discovery, Driven by Commercial Research
Table of Contents
The International Space Station (ISS) has marked a quarter-century of continuous human presence in orbit, a milestone fueled by expanding commercial opportunities and groundbreaking research facilitated by the ISS National Laboratory. Since November 2, 2000, over 290 astronauts have lived and worked aboard the station, fostering international collaboration and pushing the boundaries of scientific knowledge.
A National Laboratory Takes Shape
Recognizing the unique potential of the space environment, the U.S. Congress designated the ISS as a national laboratory in 2005. In 2011, the Center for the Advancement of Science in Space® (CASIS®) was selected by NASA to manage the ISS National Lab, a pivotal decision that unlocked access for non-governmental researchers and spurred a surge in space-based research and development. For nearly 15 years, this partnership has demonstrably increased demand for utilizing the ISS for scientific advancement.
Expanding Access to Low Earth Orbit
The ISS National Lab now controls up to 50% of flight allocation on NASA’s commercial resupply missions and dedicates a significant portion of astronaut time to research and development initiatives. Since 2011, the lab has sponsored over 900 payloads spanning diverse fields, including life sciences, physical sciences, technology development, in-space production, and STEM education. These efforts have attracted more than $80 million in funding from sources outside of NASA and engaged millions of students in preparing for the future of space exploration.
Fueling Innovation and Investment
The impact of the ISS National Lab extends beyond scientific discovery. The organization has successfully cultivated private-sector interest in the orbiting outpost, with nearly 60% of its sponsored projects originating from commercial entities – ranging from Fortune 500 companies to innovative startups. This engagement has translated into substantial investment, with companies leveraging the ISS National Lab collectively raising nearly $2.5 billion in post-flight funding, accelerating the commercialization of space-based technologies.
The ISS National Lab actively supports early-stage companies through accelerator programs, including its recently launched Orbital Edge Accelerator, which awarded six companies up to $500,000 each to launch projects to the ISS. Furthermore, over 500 peer-reviewed articles have been published based on research sponsored by the ISS National Lab, demonstrating a commitment to rigorous scientific validation.
A Growing LEO Economy
The ISS National Lab is also fostering the growth of a robust low Earth orbit (LEO) economy. Since 2011, the number of commercially owned and operated facilities on the ISS has increased from two to over 25, providing a wealth of capabilities for research and development. By supporting Commercial Service Providers, the ISS National Lab is bolstering the infrastructure needed for sustained activity in LEO. Currently, demand for access to the ISS exceeds supply, with over 100 sponsored projects awaiting a future flight opportunity.
“Twenty-five years of continuous human presence on the International Space Station is a monumental achievement not only for the space community but for all of humanity, as we see what’s possible when we collectively work toward a common goal,” said Ray Lugo, chief executive officer of CASIS. “The ISS National Lab is proud to partner with NASA to further the enduring legacy of the space station, and we look forward to continuing to enable space-based research and development to benefit humanity.”
The ISS National Laboratory, managed by CASIS under Cooperative Agreement with NASA, provides access to a unique microgravity research environment, a powerful vantage point in low Earth orbit, and the extreme conditions of space for U.S. government agencies, academic institutions, and the private sector.
