The European Space Agency (ESA) is preparing to launch a unique satellite in 2027, designed specifically to study how satellites break apart upon reentry into Earth’s atmosphere. This mission, named DRACO (Destructive Reentry Assessment Container Object), will be an important step in ESA’s effort to develop technology that limits the creation of space debris. ESA has awarded the contract to Deimos, a European technology company, to build this spacecraft, which will provide invaluable data as it breaks apart during its reentry. This data will help scientists better understand satellite disintegration and its environmental impact.
Understanding Satellite Breakup
The goal of the DRACO mission is to collect data on how satellites disintegrate during reentry. By studying this, researchers aim to design future satellites that will fully burn up during reentry, reducing the risk of debris reaching the Earth’s surface. The mission will also examine how spacecraft reentry affects the atmosphere, including how different materials interact with it and what byproducts are produced.
Innovative DRACO Design
At 200 kilograms, DRACO will be about the size of a washing machine. Its design will allow it to break apart like a normal satellite, but a specially engineered capsule will survive reentry. This capsule, measuring 40 centimetres, will carry four cameras and 200 sensors to record crucial data during the breakup. After reentry, it will deploy a parachute and transmit the collected information before being lost at sea.
Advancing Zero Debris Technology
According to Holger Krag, ESA’s Head of Space Safety, the DRACO mission will play a key role in developing future satellite technology. The data it collects will be used to build more demisable satellites by 2030, aligning with ESA’s Zero Debris charter, which aims to stop the creation of space debris within this decade.
Tim Flohrer, head of ESA’s space debris office, also emphasised the mission’s importance in helping to advance zero-debris technologies, particularly as the number of satellite launches continues to increase worldwide.
