What are Global Space Agency Applications and Strategic Priorities?

Introduction

The current era of space activity is a dynamic interplay of scientific ambition, international cooperation, and a rapidly expanding commercial sector. Once the exclusive domain of competing superpowers, space is now a global enterprise. National space agencies, from established leaders like the National Aeronautics and Space Administration (NASA) in the United States and the European Space Agency (ESA) to the increasingly influential China National Space Administration (CNSA) and Indian Space Research Organisation (ISRO), are pursuing agendas that are both visionary and pragmatic. They are joined by Russia’s Roscosmos, which builds on a long legacy of spaceflight, and the Japan Aerospace Exploration Agency (JAXA), a key partner in many international ventures.

The strategic plans of these organizations reveal a fundamental duality. On one hand, they continue to chase the horizon, funding ambitious missions to expand human knowledge, explore the solar system, and search for the origins of the universe. On the other hand, their activities are deeply intertwined with pressing terrestrial concerns. The justification for massive public investment is now frequently framed in terms of tangible benefits: tackling climate change, enhancing national security, and driving economic growth. This creates a productive tension between exploration for its own sake and the exploitation of space for strategic advantage on Earth. This article provides a global analysis of the applications these agencies are focused on, examining their priorities across five key domains: Earth observation, human spaceflight, robotic exploration, space infrastructure, and planetary defense.

Eyes on Earth: Monitoring a Changing Planet

From the vantage point of orbit, satellites provide an unparalleled perspective on Earth’s complex systems. This capability has become central to the mission of every major space agency, serving two critical functions: understanding long-term environmental change and providing actionable data for resource management and disaster response.

Climate Science and Environmental Monitoring

The global effort to understand and address climate change relies heavily on data collected from space. Satellites provide the consistent, worldwide measurements needed to track key indicators, validate climate models, and inform policy.

NASA is advancing this field with its next-generation Earth System Observatory (ESO). This series of missions is designed to provide a comprehensive, three-dimensional view of Earth’s systems, moving beyond isolated measurements to understand how the planet’s components interact. The ESO will focus on five critical areas: aerosols; clouds and precipitation; surface biology and geology; water and ice; and surface deformation. These missions build on the work of NASA’s existing fleet of over two dozen Earth science satellites, which have provided clear evidence of rising global temperatures, melting ice sheets, and increasing sea levels. The long-serving Terra satellite, for example, saw its MOPITT instrument, which tracked global carbon monoxide for 25 years, shut down in April 2025, marking a transition to newer technologies.

ESA has positioned its Earth observation programs as a cornerstone of Europe’s climate action strategy. The Copernicus Programme, a joint initiative with the European Union, is one of the world’s most ambitious Earth observation efforts, using a dedicated family of Sentinel satellites to provide a continuous stream of environmental data. A key mission, the Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) satellite, is planned for launch in 2025 and will be the first to specifically measure CO2 released into the atmosphere by human activity. This capability is explicitly designed to support international climate agreements by providing an independent source to verify national emissions inventories. In early 2025, ESA’s Biomass mission began delivering its first images, using a novel P-band radar to see through forest canopies and create a 3D map of the world’s forests, a vital tool for carbon accounting.

This push for independent verification is not unique to Europe. China has also made significant investments in this area, recently making operational its own advanced climate and carbon monitoring satellites. These include an atmospheric monitoring satellite equipped with active laser detection technology and the “Goumang” satellite, which uses a combination of active and passive sensors to monitor forest carbon sinks. In June 2025, Chinese researchers announced the development of a new satellite model specifically designed to track carbon dioxide emissions from large coal-fired power plants. This investment is directly tied to supporting China’s national goals of achieving carbon neutrality.

JAXA contributes to this global effort through its Global Change Observation Mission (GCOM), which includes satellites like “SHIKISAI” and “SHIZUKU.” These missions provide long-term, consistent data on many of the Essential Climate Variables (ECVs) identified by the Global Climate Observing System. JAXA’s data archive, spanning over three decades, has been instrumental in tracking long-term trends, such as the rapid decline of Arctic sea ice. In March 2025, data from the joint ESA-JAXA EarthCARE satellite, which studies clouds and aerosols, was made publicly available. ISRO likewise uses its extensive fleet of Earth Observation Satellites (EOS) to monitor deforestation, pollution, and other environmental indicators relevant to climate research.

The parallel development of high-precision, independent carbon monitoring capabilities by NASA, ESA, and CNSA signals a shift in the geopolitics of climate science. As international agreements like the Paris Accord rely on self-reported emissions data, the ability to independently verify these reports from space introduces a powerful new layer of transparency and accountability. A nation or bloc that can provide the “gold standard” of climate data could significantly influence international policy, trade negotiations involving carbon tariffs, and the global narrative on climate action. This transforms climate science from a purely collaborative field into one with a distinct competitive edge.

Natural Resource Management and Disaster Response

Beyond long-term climate monitoring, Earth observation satellites provide critical, often life-saving, data for managing natural resources and responding to emergencies.

NASA’s contributions in this area are extensive. The Landsat program, a joint initiative with the U.S. Geological Survey (USGS) that has been operating for over 50 years, provides an unparalleled archive of Earth’s land surfaces. This historical record is invaluable for assessing risk before a disaster and for mapping the extent of damage to guide recovery efforts after events like wildfires, floods, and volcanic eruptions. The agency’s dedicated Disasters Program works to put this data into the hands of decision-makers, providing open and accessible tools to communities worldwide to reduce the impact of natural hazards. In partnership with the National Oceanic and Atmospheric Administration (NOAA), NASA also develops and launches the Geostationary Operational Environmental Satellites (GOES). The latest in the series, GOES-19 (formerly GOES-U), was launched in June 2024 and provides continuous weather imagery essential for tracking hurricanes and forecasting severe storms.

ESA is also a major player in this domain. Its Copernicus Sentinel-2 mission supports a wide range of applications, including emergency management, agricultural monitoring, and forestry. The agency is pushing the technological frontier with projects like Ciseres, an AI-powered satellite mission designed to dramatically shorten crisis response times. By processing data on-board the satellite, Ciseres can identify a disaster like a flood or wildfire and alert first responders within minutes of its occurrence, a significant improvement over traditional methods.

Other agencies have similar priorities. ISRO’s Resourcesat series is specifically designed for mapping natural resources and supporting disaster management, and its RISAT satellites enhance India’s surveillance and disaster response capabilities. China’s constellation of over 200 remote sensing satellites provides data for disaster monitoring, while Roscosmos operates its own Earth observation satellites like the Meteor-M and Kanopus-V series.

A prime example of international collaboration in this area is the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, scheduled for launch in July 2025. This joint project will use advanced radar to systematically map our planet, providing high-resolution data to monitor natural disasters, track changes in ecosystems, and measure the motion of ice sheets and the Earth’s crust. The ability of radar to see through clouds makes it particularly valuable for monitoring events like floods and volcanic eruptions.

The increasing sophistication and near-real-time availability of this data is driving a paradigm shift from a model of “respond and recover” to one of “predict and prevent.” Missions like NISAR can detect the subtle, slow-moving deformation of the ground that can precede earthquakes and volcanic eruptions. AI-powered systems like Ciseres can provide almost instantaneous alerts. This move from reactive assessment to proactive warning has significant implications. Insurance companies can use this data for more dynamic risk modeling, urban planners can reinforce vulnerable infrastructure before a predicted event, and humanitarian organizations can pre-position resources more effectively, ultimately saving lives and reducing economic losses.

The Human Frontier: Extending Presence in Space

Sending humans into space remains a pinnacle of technological achievement and a powerful symbol of national ambition. The focus of these efforts is twofold: maintaining a continuous presence in low Earth orbit (LEO) to conduct research and test technologies, and pushing further out to establish a sustainable human foothold on the Moon and prepare for eventual missions to Mars.

The Low Earth Orbit Ecosystem

For over two decades, low Earth orbit has been the primary domain of human spaceflight, centered on the International Space Station (ISS).

The ISS is a testament to international cooperation, a joint project of NASA, Roscosmos, ESA, JAXA, and the Canadian Space Agency (CSA). It serves as a unique microgravity laboratory where astronauts conduct research in fields ranging from biology and materials science to human physiology, providing knowledge that benefits life on Earth and prepares for future deep-space missions. Roscosmos continues to be a vital partner, providing reliable crew and cargo transportation with its Soyuz and Progress spacecraft, though it has announced its intention to leave the partnership by 2028.

While the ISS partnership continues, China has established its own independent outpost in LEO. The Tiangong space station (“Heavenly Palace”) is a modern, modular station that is permanently crewed by Chinese astronauts, known as taikonauts. Though smaller than the ISS, Tiangong is a sophisticated platform with multiple modules, including the Tianhe core module and the Wentian and Mengtian laboratory modules, which support a wide array of scientific experiments. This gives China a sovereign capability for long-duration human spaceflight and microgravity research, independent of the ISS partnership. China plans to launch the Xuntian Space Telescope in mid-2025, which will co-orbit with Tiangong, allowing for regular servicing.

As the ISS approaches its planned decommissioning around 2031, NASA is actively working to ensure there is no gap in U.S. presence in LEO. The agency’s strategy is to foster a commercial LEO economy, transitioning from the role of owner-operator to that of a customer. NASA is supporting private companies in the development of commercial space stations. In June 2025, ESA signed a memorandum of understanding with Blue Origin and Thales Alenia Space to explore collaboration on the Orbital Reef station. Axiom Space is also developing its own station modules and is preparing for its fourth private astronaut mission to the ISS, Ax-4, which is scheduled to launch on June 25, 2025. The plan is for NASA to purchase services and lease space on these future commercial outposts for its research and technology development needs, creating a competitive marketplace in orbit.

Return to the Moon and On to Mars

The next great leap in human exploration is the return to the Moon, this time with the goal of establishing a sustainable presence.

NASA is leading this charge with its Artemis program. The program’s overarching goals are to land the first woman and first person of color on the Moon, conduct new scientific discovery, stimulate a lunar economy, and use the experience gained to prepare for the first human missions to Mars. Following a successful uncrewed test flight, NASA is now targeting September 2025 for Artemis II, the first crewed flight around the Moon, and September 2026 for Artemis III, the first crewed landing near the lunar South Pole. The architecture of Artemis is built on several key components: the powerful Space Launch System (SLS) rocket, the Orion crew spacecraft, the Lunar Gateway (a small space station that will orbit the Moon), and human landing systems developed by commercial partners.

Artemis is a fundamentally international endeavor, built on a broad coalition of partners. ESA is a major contributor, providing the European Service Module for the Orion spacecraft, which supplies power and propulsion, as well as habitation and infrastructure modules for the Gateway. JAXA is developing a pressurized rover that will allow astronauts to travel across the lunar surface for extended periods. The Canadian Space Agency is providing the Canadarm3, an advanced robotic arm for the Gateway. These collaborations are governed by the Artemis Accords, a set of principles for peaceful and transparent cooperation in space exploration that has been signed by dozens of countries.

China and Russia are pursuing a separate path. China has a highly successful robotic lunar exploration program (Chang’e) and has announced plans for a crewed landing by 2030. This is part of a long-term vision to build an International Lunar Research Station (ILRS) at the Moon’s south pole. Roscosmos has signed on as a primary partner in this endeavor, and the list of participating nations and organizations has grown to include countries like Venezuela, South Africa, Pakistan, Belarus, Egypt, Thailand, Nicaragua, Serbia, and Kazakhstan.

India is also setting its sights on deep space. ISRO’s Gaganyaan program aims to achieve independent human spaceflight capability. Following a series of uncrewed test flights, the first crewed mission is now expected in early 2027. This is a stepping stone toward a more ambitious long-term vision that includes establishing an Indian space station, the Bharatiya Antariksh Station (BAS), by 2035 and landing an Indian astronaut on the Moon by 2040.

The Rise of Commercial Crew and Cargo

A transformative shift in human spaceflight has been the embrace of public-private partnerships for routine transportation to and from low Earth orbit.

NASA’s Commercial Crew Program is the leading example of this new model. Instead of designing, owning, and operating its own crew transportation system, as it did with the Space Shuttle, NASA now purchases transportation as a service from commercial companies, namely SpaceX and Boeing. This approach was intended to foster competition, reduce costs, and allow NASA to redirect its own resources toward the development of deep-space systems like the SLS and Orion. Since its first operational flight in 2020, SpaceX’s Crew Dragon has provided regular transportation for astronauts to the ISS. Boeing’s CST-100 Starliner had its first crewed test flight in June 2024, but after encountering technical issues, its next flight is not expected until early 2026.

ESA is adopting a similar strategy to cultivate a competitive European commercial launch sector. Through its Boost! program, ESA co-funds and provides technical expertise to private companies like Isar Aerospace and Rocket Factory Augsburg as they develop new launch services. In this model, ESA acts as an anchor customer and partner, rather than the traditional owner and operator of the system. ESA is also planning to hold a competition for a commercial cargo vehicle to service the ISS, further stimulating the private market.

This global activity reveals two diverging models for organizing human space exploration. The “Partnership Model,” led by NASA’s Artemis program, is structured as a network, distributing the costs and development work among a broad coalition of international agencies and commercial providers. The “Independent Model,” pursued by China, focuses on developing a comprehensive, state-led sovereign capability first, and then inviting select international partners to participate in its projects, such as the ILRS. This sets up two competing ecosystems for the future of space exploration, which will likely shape geopolitical alliances and the norms of behavior on the Moon and beyond.

The Quest for Knowledge: Robotic and Scientific Exploration

While human missions capture the public imagination, much of our understanding of the cosmos comes from a relentless fleet of robotic explorers. These uncrewed missions venture to places too distant or dangerous for humans, sending back data that rewrites textbooks and reshapes our view of the universe.

Probing the Solar System

The robotic exploration of our solar system is a vibrant and competitive field, with multiple agencies targeting planets, moons, and asteroids.

Mars remains a primary focus. NASA continues its decades-long investigation of the Red Planet with advanced rovers like Curiosity and Perseverance, which are actively searching for signs of past microbial life and caching rock samples for a future return to Earth. The Mars Sample Return mission is currently undergoing further study, with a final decision on its architecture expected in mid-2026. China made a dramatic entrance to this field with its Tianwen-1 mission, which successfully placed an orbiter, lander, and the Zhurong rover at Mars in a single campaign. ESA’s ExoMars Trace Gas Orbiter continues to study the Martian atmosphere, and the agency is advancing its Rosalind Franklin rover mission, now slated for a 2028 launch with NASA support. ISRO, which achieved Mars orbit on its first attempt with the Mangalyaan mission, is planning a follow-up lander mission.

The scientific exploration of asteroids and comets has also intensified, driven by the desire to understand the building blocks of the solar system. JAXA established itself as a leader in this area with its groundbreaking Hayabusa and Hayabusa2 missions, which were the first to return samples from asteroids to Earth. NASA followed with its own successful sample return mission, OSIRIS-REx, which brought back material from the asteroid Bennu. China’s Tianwen-2 mission, which launched in May 2025, is now on its way to visit the near-Earth asteroid Kamo’oalewa. ESA is also active in this domain with its Hera mission, which launched in October 2024 and is en route to a binary asteroid, and the ambitious Comet Interceptor, which will be the first spacecraft to visit a pristine, long-period comet just entering the inner solar system.

The frontiers of exploration are also being pushed to the outer solar system and back to our nearest planetary neighbor, Venus. ESA’s Jupiter Icy Moons Explorer (JUICE) is currently en route to Jupiter, where it will conduct detailed studies of the potentially life-bearing ocean worlds Europa, Ganymede, and Callisto; it is scheduled for a Venus flyby in August 2025. NASA’s Juno mission continues to orbit and study Jupiter’s atmosphere and magnetic field. China is planning its own mission to Jupiter and its moon Callisto, with a possible flyby of Uranus. The intense, greenhouse-shrouded world of Venus is also the target of a new wave of missions, with plans in development by NASA, ESA (EnVision), ISRO (Shukrayaan, now planned for 2028), and Roscosmos (Venera-D).

Gazing into the Cosmos

To answer the biggest questions about the universe – its origins, evolution, and composition – space agencies build and operate powerful space-based observatories.

The Hubble Space Telescope, a long-standing collaboration between NASA and ESA, has been one of the most productive scientific instruments ever built, changing our fundamental understanding of the cosmos for over three decades. Its successor, the James Webb Space Telescope (JWST), is an even more powerful collaboration between NASA, ESA, and the CSA. Peering into the universe in infrared light, JWST is designed to see the very first stars and galaxies that formed after the Big Bang and to study the atmospheres of planets orbiting other stars.

Looking ahead, agencies are planning the next generation of cosmic observatories. ESA’s Euclid mission is currently mapping the geometry of the dark universe to understand the nature of dark matter and dark energy. The agency’s future PLATO and ARIEL missions will be dedicated to finding and characterizing exoplanets. China is also developing a major space observatory, the Xuntian Space Telescope, which is planned for launch in mid-2025 and will co-orbit with the Tiangong space station, allowing for regular servicing and upgrades by taikonauts.

While flagship missions like JWST represent massive, decadal-long international efforts, a clear trend toward “mission diversification” is emerging. Agencies are pursuing a wider range of smaller, more focused missions, often through new and more varied partnerships. For example, JAXA is collaborating with ISRO on a lunar rover, and with ESA on missions to Mercury and an asteroid. China is working with France on an astronomical satellite and has provided payload slots on its lunar missions to partners like Pakistan and Thailand. This diversification is enabled by the high cost of flagship missions, which encourages cost-sharing, and by the miniaturization of technology and increased availability of commercial launch services, which make smaller missions more feasible. This approach creates a more resilient and dynamic global science program, allowing more nations to participate in meaningful space science and potentially accelerating the pace of discovery.

Building the Infrastructure of Space

All space activities, from a simple Earth-observation satellite to a crewed mission to Mars, depend on a foundation of critical infrastructure. This includes systems for navigation and positioning, networks for communication, and vehicles for launching payloads into orbit. Control over this infrastructure is a key measure of a nation’s strategic autonomy in space.

Global Navigation and Positioning

Global Navigation Satellite Systems (GNSS) are constellations of satellites that provide precise positioning, navigation, and timing (PNT) data to users on the ground, in the air, and in space. There are currently four primary global systems, each operated by a major space power.

The United States’ Global Positioning System (GPS) is the oldest and most widely used GNSS. Operated by the U.S. Space Force, it provides dual services for both civilian and military users worldwide. NASA is a key user of GPS, developing advanced receivers and applications to enable greater autonomy for its spacecraft and to support its Earth science missions.

Europe’s Galileo system, operated by the EU through EUSPA with design and development led by ESA, was created to provide the continent with strategic autonomy from the military-controlled GPS and GLONASS systems. It is under civilian control and offers highly accurate, dual-frequency signals to all users. A unique feature is its Search and Rescue (SAR) service, which can send a return signal to a user in distress, confirming that their alert has been received.

Russia’s GLONASS (Global Navigation Satellite System), operated by Roscosmos, provides the Russian Federation with its own independent navigation capability. After a period of degradation, the constellation has been fully restored and is being modernized with the deployment of new-generation Glonass-K2 satellites, with over ten planned to be in orbit by 2028. Its orbital configuration provides particularly strong coverage in high-latitude regions.

China’s BeiDou Navigation Satellite System (BDS) is the newest of the four global systems. Operated by the CNSA, it was developed in three phases, achieving full global coverage with the BeiDou-3 constellation. Its architecture is unique, employing satellites in geostationary (GEO), inclined geosynchronous (IGSO), and medium Earth orbits (MEO) to enhance accuracy, particularly over the Asia-Pacific region. It also integrates a short message communication service, a capability not found in the other systems.

Space Communications

Reliable communication is the lifeline of any space mission. NASA operates two primary networks to maintain contact with its spacecraft: the Near Space Network (NSN) for missions in Earth orbit, and the Deep Space Network (DSN) for interplanetary missions. The DSN is a global network of large radio antennas located in the United States, Spain, and Australia, ensuring that a spacecraft is always in view of at least one station as the Earth rotates. To meet the demand for higher data rates from advanced scientific instruments, NASA is also pioneering Deep Space Optical Communications (DSOC), which uses lasers instead of radio waves and can increase data return by a factor of 10 to 100. As its legacy Tracking and Data Relay Satellite (TDRS) system ages, NASA is increasingly looking to commercial providers to supply near-Earth communication services, issuing a request for information to industry in June 2025. ESA, Roscosmos, and CNSA also operate their own independent ground station and data relay networks to support their missions.

Assured Access to Space

The ability to reliably and affordably launch payloads into space is foundational to any space program. This area has seen the most dramatic transformation due to the rise of the commercial sector.

NASA’s Launch Services Program (LSP) now functions as a broker, procuring launches for the agency’s science and robotic missions from a diverse fleet of commercial providers, including established players like United Launch Alliance and new entrants like SpaceX and Rocket Lab. This public-private partnership model is designed to foster a competitive marketplace, drive down costs, and ensure NASA has multiple options for getting its valuable assets into orbit.

ESA is pursuing a similar strategy to ensure European autonomy in space access. Its Boost! program and the European Launcher Challenge are designed to support emerging commercial launch providers. ESA provides co-funding and technical expertise, acting as a partner and anchor customer to help these companies develop commercially viable services. This is a strategic evolution from the highly successful Ariane rocket program. The new Ariane 6 rocket had its first commercial flight in March 2025, a key milestone for European launch capabilities.

While embracing commercial partnerships, major space powers like China (with its Long March family), Russia (Soyuz, Proton, and the new Angara), India (PSLV and GSLV), and Japan (H-IIA and Epsilon) all maintain robust, state-led sovereign launch capabilities. These programs are considered critical national assets. The development of reusable rocket technology, pioneered by SpaceX, has become a major focus for many of these national and commercial programs, as it promises to further reduce the cost of access to space.

This shift across the global space infrastructure landscape is significant. Government agencies, particularly in the West, are moving from being owners and operators of infrastructure to becoming anchor tenants or customers of commercially provided services. This fosters a more agile and innovative ecosystem but also introduces new dependencies on the financial and technical success of private companies. It requires a new form of government oversight focused on certification and risk management, and it creates a new arena for global economic competition based on the strength of a nation’s commercial space sector.

Safeguarding the Future: Planetary Defense and Sustainability

As humanity’s activities in space expand, two new strategic imperatives have come into sharp focus: protecting the Earth from the threat of an asteroid impact and ensuring the long-term sustainability of the orbital environment.

Defending the Planet

The threat of a large asteroid or comet impacting Earth is a low-probability but high-consequence risk that has mobilized a global, collaborative response.

NASA’s Planetary Defense Coordination Office (PDCO), established in 2016, leads the U.S. government’s efforts in this area. The PDCO’s strategy is comprehensive, covering the enhancement of NEO detection and tracking, the improvement of impact modeling, the development of deflection technologies, and the fostering of international cooperation. A key element of this strategy is the effort to catalogue all potentially hazardous NEOs. This is currently done through a network of ground-based telescopes, such as the Catalina Sky Survey, but will be dramatically accelerated by the upcoming NEO Surveyor space telescope, which is now planned to launch in September 2027 and is designed to find over 90 percent of hazardous objects larger than 140 meters in diameter.

In 2022, NASA conducted the world’s first successful planetary defense test mission. The Double Asteroid Redirection Test (DART) spacecraft intentionally collided with Dimorphos, the small moon of the asteroid Didymos. The mission proved that a kinetic impactor could successfully alter an asteroid’s trajectory. The impact was even more effective than predicted, shortening Dimorphos’s orbit by 33 minutes and physically reshaping the small asteroid, providing invaluable data on the properties of “rubble-pile” asteroids.

To fully understand the results of the DART impact, ESA launched the Hera mission in October 2024. Now en route to the Didymos system, Hera will conduct a detailed post-impact survey, measuring Dimorphos’s mass, composition, and the precise characteristics of the crater left by DART. This follow-up mission is essential for turning the DART experiment into a well-understood and repeatable planetary defense technique.

Planetary defense is an inherently global challenge, and international cooperation is robust. Agencies coordinate their efforts through the United Nations-endorsed International Asteroid Warning Network (IAWN) for observation and the Space Mission Planning Advisory Group (SMPAG) for mitigation planning. China is also developing its own planetary defense capabilities, including a planned asteroid impact test mission.

Space Sustainability and Debris Mitigation

The success of the space industry has created a new challenge: the growing problem of orbital debris. Decades of launches have left thousands of defunct satellites, rocket stages, and fragments of collisions in orbit, posing a significant threat to active satellites and future missions.

ESA has taken a leading role in promoting space sustainability. The agency has championed a Zero Debris Charter, a voluntary commitment by space actors to stop generating new debris in valuable orbits by 2030, which continues to gain signatories. Beyond prevention, ESA is also developing technologies for active debris removal. Its ClearSpace-1 mission, scheduled for launch in 2025, will be the first to capture and de-orbit a piece of existing space junk.

JAXA is also actively working on this problem. Its Commercial Removal of Debris Demonstration (CRD2) Phase I mission, conducted with the private company Astroscale, successfully completed its on-orbit demonstrations in early 2025. Phase II of the mission, which will attempt to capture and de-orbit a piece of debris, is planned for 2027. Recognizing the future scale of the problem, China, which is planning to deploy its own satellite mega-constellations, has announced its intention to develop a comprehensive space traffic management system to coordinate operations and prevent collisions.

These efforts highlight a potential conflict at the heart of the new space age. On one hand, agencies and commercial entities are publicly committing to sustainability and developing mitigation technologies. On the other hand, the intense economic and strategic pressures to deploy massive constellations of thousands of satellites for communications, navigation, and surveillance are adding objects to orbit far faster than any debris removal technology can take them away. This creates a classic “tragedy of the commons” scenario in space. The short-term benefit of deploying a large constellation may outweigh the long-term collective cost of a more hazardous orbital environment. Without strong, internationally binding rules for space traffic management and debris mitigation, the problem is likely to become significantly worse, potentially threatening the viability of all future space activities.

Summary

The applications that global space agencies are focused on today reflect a new era of space activity, one defined by a complex blend of scientific curiosity, strategic necessity, and economic opportunity. The world’s leading space agencies – NASA, ESA, Roscosmos, CNSA, ISRO, and JAXA – are pursuing a dual-track agenda. They are simultaneously looking outward, sending robotic and human explorers to the Moon, Mars, and beyond to answer fundamental questions about our place in the universe, and looking back at Earth, using space-based assets to address some of the most pressing challenges of our time.

Earth observation has become a cornerstone of this pragmatic approach. Satellites are now indispensable tools for monitoring climate change, managing natural resources, and providing life-saving data for disaster response. The development of independent, high-precision carbon monitoring satellites by multiple powers is even creating a new form of geopolitical accountability.

In human spaceflight, two distinct models of exploration are taking shape. One, led by NASA’s Artemis program, is a networked partnership of international agencies and commercial companies sharing the costs and capabilities of returning to the Moon. The other, led by China, is a more state-centric model focused on developing sovereign capabilities first, then inviting partners to participate in its ambitious projects, like the International Lunar Research Station.

This divergence is mirrored in the development of space infrastructure. While all major powers maintain sovereign launch and navigation systems as critical national assets, Western agencies are increasingly embracing a new paradigm of public-private partnership. They are shifting from being owners and operators of infrastructure to becoming anchor customers for commercial services, a move designed to spur innovation and reduce costs. This has transformed the space industry, creating a more agile and competitive ecosystem but also introducing new dependencies on the commercial sector.

As humanity’s footprint in space grows, new challenges have emerged that require unprecedented global cooperation. Planetary defense, the effort to protect Earth from asteroid impacts, has become a vibrant area of international collaboration, exemplified by the partnership between NASA’s DART mission and ESA’s Hera follow-up. At the same time, the growing problem of orbital debris poses a threat to the long-term sustainability of all space activities, creating a tension between the rush to deploy new satellite constellations and the collective need to preserve the space environment for future generations. Space agencies are no longer just exploration bodies; they are multifaceted organizations operating at the nexus of science, technology, economics, and international relations, actively shaping the future both in orbit and on Earth.
