ADEO: a new chapter in space history in six seconds
Historical video evidence
from HPS and D-Orbit
On December 15, 2022, at 12:10 UTC, the world’s unique ADEO braking sail from the German space technology company HPS GmbH, Munich, opened the chapter of sustainability for international spaceflight 500 kilometers above the Earth: as planned, on time and precisely, the sail attached to the ION SCV 003 satellite unfurled over an area of 3.6 square meters to remove “its” satellite from orbit in the shortest possible time without leaving any residue, thus avoiding hazards for other space vehicles and making room for the next generation of satellites at its former orbital position. Preliminary studies and calculations indicate that this will reduce the descent time not by half, as originally expected, but rather by as much as five times.
The attached video, recorded directly on site with the on-board camera of the ION satellite of the Italian cooperation partner D-Orbit, provides live proof: with the product of HPS, which is now ready for series production after twelve years of development with great support from ESA, DLR and the Bavarian government, a new era of responsibility in space is beginning. ADEO is manufactured in series by HPS at its sites in Munich and Bucharest, primarily for constellation satellites. ADEO products are available for satellites weighing up to 2,500 kilograms at flight altitudes of up to 800 km. Even higher-flying satellites can be operated with ADEO if they have previously lowered their orbit accordingly using their own propulsion. HPS CEO Ernst K. Pfeiffer: “With ADEO on board, satellites do not become space junk in the first place. And at conditions that are ALWAYS more economical than all other options.”
