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.

Video: 00:15:30 Meet Arnaud Prost—aerospace engineer, professional diver, and member of ESA’s Astronaut Reserve. From flying aircraft to getting a taste of spacewalk simulation, his passion for exploration knows no bounds.
In this miniseries, we take you on a journey through the ESA Astronaut Reserve, diving into the first part of their Astronaut Reserve Training (ART) at the European Astronaut Centre (EAC) near Cologne, Germany. Our “ARTists” are immersing themselves in everything from ESA and the International Space Station programme to the European space industry and institutions. They’re gaining hands-on experience in technical skills like spacecraft systems and robotics, alongside human behaviour, scientific lessons, scuba diving, and survival training.
ESA’s Astronaut Reserve Training programme is all about building Europe’s next generation of space explorers—preparing them for the opportunities of future missions in Earth orbit and beyond.
This interview was recorded in November 2024.
You can listen to this episode on all major podcast platforms.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
For Anum Ashraf, Ph.D., the interconnectedness of NASA’s workforce presents the exciting opportunity to collaborate with a multitude of people and teams. With more than 11 years at the agency, Ashraf has played a fundamental role in leading efforts that actively bridge these connections and support NASA’s mission.
Ashraf serves as the mission commitment lead for NASA’s SCaN (Space Communication and Navigation) Program, which is managed through the agency’s Space Operations Mission Directorate. SCaN provides communications and navigation services that are essential to the operation of NASA’s spaceflight missions, including enabling the success of more than 100 NASA and non-NASA missions through the Near Space Network and Deep Space Network. Whether she is supporting missions involving astronauts in space or near-Earth missions monitoring the health of our planet, Ashraf ensures that critical data is efficiently transferred between groups.

“I am the ‘front door’ for all missions that are requesting space communication through the SCaN program,” said Ashraf. “My job is to understand the mission requirements and pair them with the right assets to enable successful back and forth communication throughout their mission life cycle.”
Prior to her current role, Ashraf served as the principal investigator for the DEMETER (DEMonstrating the Emerging Technology for measuring the Earth’s Radiation) project at NASA’s Langley Research Center in Hampton, Virginia. DEMETER is the next-generation observational platform for measuring Earth’s radiation. Leading a team of engineers and scientists across NASA’s multifaceted organizations, Ashraf helped develop an innovative solution that will allow future researchers to assess important climate trends affecting the planet.
Outside of work, Ashraf finds a creative outlet through hobbies like knitting, cross stitching, and playing piano. She brings her ambitious, passionate, and authentic qualities to caring for her two children, who are also her daily source of inspiration.
“Inspiration is a two-way street for me; my kids inspire me to be my best, and, in turn, I inspire them,” said Ashraf. “My kids love telling their friends that we are a NASA family.”

Looking toward the future, Ashraf is excited to see a collaboration between NASA, industry, academia, and international space enthusiasts working together towards a common goal of space exploration. As a devoted and collaborative leader, Ashraf will continue to play an important role in advancing the agency’s missions of space research and exploration.
NASA’s Space Operations Mission Directorate maintains a continuous human presence in space for the benefit of people on Earth.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 quiet supersonic research aircraft sits on a ramp at Lockheed Martin Skunk Works in Palmdale, California, during sunset. The one-of-a-kind aircraft is powered by a General Electric F414 engine, a variant of the engines used on F/A-18 fighter jets. The engine is mounted above the fuselage to reduce the number of shockwaves that reach the ground. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight and enable future commercial travel over land – faster than the speed of sound.Lockheed Martin Corporation/Garry Tice The team behind NASA’s X-59 completed another critical ground test in March, ensuring the quiet supersonic aircraft will be able to maintain a specific speed during operation. The test, known as engine speed hold, is the latest marker of progress as the X-59 nears first flight this year.
“Engine speed hold is essentially the aircraft’s version of cruise control,” said Paul Dees, NASA’s X-59 deputy propulsion lead at the agency’s Armstrong Flight Research Center in Edwards, California. “The pilot engages speed hold at their current speed, then can adjust it incrementally up or down as needed.”
The X-59 team had previously conducted a similar test on the engine – but only as an isolated system. The March test verified the speed hold functions properly after integration into the aircraft’s avionics.
“We needed to verify that speed hold worked not just within the engine itself but as part of the entire aircraft system.” Dees explained. “This test confirmed that all components – software, mechanical linkages, and control laws – work together as intended.”
The successful test confirmed the aircraft’s ability to precisely control speed, which will be invaluable during flight. This capability will increase pilot safety, allowing them to focus on other critical aspects of flight operation.
“The pilot is going to be very busy during first flight, ensuring the aircraft is stable and controllable,” Dees said. “Having speed hold offload some of that workload makes first flight that much safer.”
The team originally planned to check the speed hold as part of an upcoming series of ground test trials where they will feed the aircraft with a robust set of data to verify functionality under both normal and failure conditions, known as aluminum bird tests. But the team recognized a chance to test sooner.
“It was a target of opportunity,” Dees said. “We realized we were ready to test engine speed hold separately while other systems continued with finalizing their software. If we can learn something earlier, that’s always better.”
With every successful test, the integrated NASA and Lockheed Martin team brings the X-59 closer to first flight, and closer to making aviation history through quiet supersonic technology.
