Video: 00:08:04 Space Debris: Is it a Crisis?
The European Space Agency’s short documentary film ‘Space Debris: Is it a Crisis?’ on the state of space debris premiered at the 9th European Conference on Space Debris on 1 April 2025.
Earth is surrounded by thousands of satellites carrying out important work to provide telecommunications and navigation services, help us understand our climate, and answer fundamental questions about the Universe.
However, as our use of space accelerates like never before, these satellites find themselves navigating increasingly congested orbits in an environment criss-crossed by streams of fast-moving debris fragments resulting from collisions, fragmentations and breakups in space.
Each fragment can damage additional satellites, with fears that a cascade of collisions may eventually render some orbits around Earth no longer useable. Additionally, the extent of the harm of the drastic increase in launches and number of objects re-entering our atmosphere and oceans is not yet known.
So, does space debris already represent a crisis?
The documentary explores the current situation in Earth’s orbits and explains the threat space debris poses to our future in space. It also outlines what might be done about space debris and how we might reach true sustainability in space, because our actions today will have consequences for generations to come.
ESA’s Space Safety Programme
ESA’s Space Safety Programme aims to safeguard the future of spaceflight and to keep us, Earth and our infrastructure on the ground and in space safe from hazards originating in space.
From asteroids and solar storms to the human-made problem of space debris, ESA works on missions and projects to understand the dangers and mitigate them.
In the longer term, to ensure a safe and sustainable future in space, ESA aims to establish a circular economy in space. To get there, the Agency is working on the technology development necessary to make in-orbit servicing and zero-debris spacecraft a reality.

NASA astronauts Commander Zena Cardman and Pilot Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Mission Specialist Kimiya Yui, and Roscosmos cosmonaut Mission Specialist Oleg Platonov will join crew members aboard the space station no earlier than July 2025.
The flight is the 11th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions to the Moon, as well as benefit people on Earth.
Cardman previously was assigned to NASA’s SpaceX Crew-9 mission, and Fincke previously was assigned to NASA’s Boeing Starliner-1 mission. NASA decided to reassign the astronauts to Crew-11 in overall support of planned activities aboard the International Space Station. Cardman carries her experience training as a commander on Dragon spacecraft, and Fincke brings long-duration spaceflight experience to this crew complement.
Selected as a NASA astronaut in 2017, Cardman will conduct her first spaceflight. The Williamsburg, Virginia, native holds a bachelor’s degree in Biology and a master’s in Marine Sciences from the University of North Carolina at Chapel Hill. At the time of selection, she had begun pursuing a doctorate in Geosciences. Cardman’s research in geobiology and geochemical cycling focused on subsurface environments, from caves to deep sea sediments. Since completing initial training, Cardman has supported real-time station operations and lunar surface exploration planning.
This will be Fincke’s fourth trip to the space station, having logged 382 days in space and nine spacewalks during Expedition 9 in 2004, Expedition 18 in 2008, and STS-134 in 2011, the final flight of space shuttle Endeavour. Throughout the past decade, Fincke has applied his expertise to NASA’s Commercial Crew Program, advancing the development and testing of the SpaceX Dragon and Boeing Starliner toward operational certification. The Emsworth, Pennsylvania, native is a distinguished graduate of the United States Air Force Test Pilot School and holds bachelors’ degrees from the Massachusetts Institute of Technology, Cambridge, in both Aeronautics and Astronautics, as well as Earth, Atmospheric and Planetary Sciences. He also has a master’s degree in Aeronautics and Astronautics from Stanford University in California. Fincke is a retired U.S. Air Force colonel with more than 2,000 flight hours in more than 30 different aircraft.
With 142 days in space, this will be Yui’s second trip to the space station. After his selection as a JAXA astronaut in 2009, Yui flew as a flight engineer for Expedition 44/45 and became the first Japanese astronaut to capture JAXA’s H-II Transfer Vehicle. In addition to constructing a new experimental environment aboard Kibo, he conducted a total of 21 experiments for JAXA. In November 2016, Yui was assigned as chief of the JAXA Astronaut Group. He graduated from the School of Science and Engineering at the National Defense Academy of Japan in 1992. He later joined the Air Self-Defense Force at the Japan Defense Agency (currently Ministry of Defense). In 2008, Yui joined the Air Staff Office at the Ministry of Defense as a lieutenant colonel.
The Crew-11 mission will be Platonov’s first spaceflight. Before his selection as a cosmonaut in 2018, Platonov earned a degree in Engineering from Krasnodar Air Force Academy in Aircraft Operations and Air Traffic Management. He also earned a bachelor’s degree in State and Municipal Management in 2016 from the Far Eastern Federal University in Vladivostok, Russia. Assigned as a test cosmonaut in 2021, he has experience in piloting aircraft, zero gravity training, scuba diving, and wilderness survival.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.

A SpaceX Falcon 9 rocket lifts off from Vandenberg Space Force Base, carrying NASA’s EZIE spacecraft into orbit. SpaceX Under the nighttime California sky, NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission launched aboard a SpaceX Falcon 9 rocket at 11:43 p.m. PDT on March 14.
Taking off from Vandenberg Space Force Base near Santa Barbara, the EZIE mission’s trio of small satellites will fly in a pearls-on-a-string configuration approximately 260 to 370 miles above Earth’s surface to map the auroral electrojets, powerful electric currents that flow through our upper atmosphere in the polar regions where auroras glow in the sky.
At approximately 2 a.m. PDT on March 15, the EZIE satellites were successfully deployed. Within the next 10 days, the spacecraft will send signals to verify they are in good health and ready to embark on their 18-month mission.
“NASA has leaned into small missions that can provide compelling science while accepting more risk. EZIE represents excellent science being executed by an excellent team, and it is delivering exactly what NASA is looking for,” said Jared Leisner, program executive for EZIE at NASA Headquarters in Washington.
The electrojets — and their visible counterparts, theauroras — are generated duringsolar storms when tremendous amounts of energy get transferred into Earth’s upper atmosphere from the solar wind. Each of the EZIE spacecraft will map the electrojets, advancing our understanding of the physics of how Earth interacts with its surrounding space. This understanding will apply not only to our own planet but also to any magnetized planet in our solar system and beyond. The mission will also help scientists create models for predicting space weather to mitigate its disruptive impacts on our society.
“It is truly incredible to see our spacecraft flying and making critical measurements, marking the start of an exciting new chapter for the EZIE mission,” said Nelli Mosavi-Hoyer, project manager for EZIE at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. “I am very proud of the dedication and hard work of our team. This achievement is a testament to the team’s perseverance and expertise, and I look forward to the valuable insights EZIE will bring to our understanding of Earth’s electrojets and space weather.”
Instead of using propulsion to control their polar orbit, the spacecraft will actively use drag experienced while flying through the upper atmosphere to individually tune their spacing. Each successive spacecraft will fly over the same region 2 to 10 minutes after the former.
“Missions have studied these currents before, but typically either at the very large or very small scales,” said Larry Kepko, EZIE mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “EZIE will help us understand how these currents form and evolve, at scales we’ve never probed.”
The mission team is also working to distribute magnetometer kits called EZIE-Mag, which are available to teachers, students, and science enthusiasts who want to take their own measurements of the Earth-space electrical current system. EZIE-Mag data will be combined with EZIE measurements made from space to assemble a clear picture of this vast electrical current circuit.
The EZIE mission is funded by the Heliophysics Division within NASA’s Science Mission Directorate and is managed by the Explorers Program Office at NASA Goddard. The Johns Hopkins Applied Physics Laboratory leads the mission for NASA. Blue Canyon Technologies in Boulder, Colorado, built the CubeSats, and NASA’s Jet Propulsion Laboratory in Southern California built the Microwave Electrojet Magnetogram, which will map the electrojets, for each of the three satellites.
