WILD RIDE mission ends with fireworks of success for deorbit sail ADEO-N2

Three days ago, on December 8, 2024, HPS received confirmation that ADEO-N2 completed its mission with launch in 2021 and end-of-business with deployment of the dragsail at 506 km orbit altitude in December 2022 in a record time of only two years with a firework of success, beating international rules and regulations by three full years. This is further proof of the success of the German ADEO model, which is manufactured in series production by the German world market leader HPS for all sizes of LEO satellites in five ADEO versions. ADEO fulfils the “5-year rule” already issued by several states and organizations for obtaining launch and operating permits for satellites, and with “Wild Ride” this has now even been verified in orbit by precisely tracking the deorbit curve until the satellite burns up completely at an orbital altitude of approx. 127 km (see image).

About the mission:
On June 30, 2021, D-Orbit, a leading company in the space logistics and orbital transportation industry from Italy, announced the successful launch of another ION Satellite Carrier (ION SCV 003), its proprietary orbital transport vehicle. It lifted off at 9:31 p.m. CEST on June 30, 2021 atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station (CCSFS), Florida. That same day, 60 minutes after launch, the vehicle was successfully placed into a 500 km high Sun Synchronous Orbit (SSO).
ION Satellite Carrier is a space transporter developed, manufactured and operated by D-Orbit. ION is capable of accommodating multiple satellites, transporting them into space, performing orbital maneuvers and precisely releasing them into dedicated orbital positions.
At the end of the so-called WILD RIDE mission, the ION SCV 003, weighing 210 kg at the time, entered the deorbit phase on December 15,2022 with the deployment of ADEO-N2 (effective sail size 3.6 m2, christened “Show me your Wings”) entered the deorbit phase and began testing the world’s first precise functional in-situ verification of a dragsail, with official “end of flight” on 08.12.2024 [source: NORAD], i.e. within exactly 2 years in a completely natural way and without exhaust gases from any propulsion system. Without sails, SCV-003’s deorbit would have taken twice to three times as long.

About ADEO:
ADEO-N is a 1U-sized deorbit sail module developed by the German space company HPS, in cooperation with several companies and institutions (e.g. DLR and Fraunhofer), co-funded by the ESA-GSTP program, the German national technology program, and the Bavarian technology program. In accordance with the new rules, ADEO ensures the removal of end-of-life satellites from LEO within a maximum of 5 years.

HPS and EXOLAUNCH: Making Space Clean Again

HPS is happy to join forces with the Germany-based Exolaunch and is fully engaged to support customers of Exolaunch by enabling this very special and successful NewSpace-launch service provider to grant priority access to the delivery schedule of flight-proven ADEO* deorbit sails which are currently in high demand.

EXOLAUNCH’s COO Jeanne Allarie and HPS’s CEO Ernst Pfeiffer signed an Agreement on Space Tech Expo 2024 in Bremen in a great joint spirit (see pictures) the ambitious endeavour of

• being a role model for a sustainable use of space and
• of raising awareness with all potential customers on an existing solution for deorbiting: ADEO-modules are easy, affordable and reliable to contributing significantly to Making Space Clean Again.

See for the respective EXOLAUNCH announcement

(* ADEO-modules are needed to allow a satellite deorbit after its “End-of-Business” within five years; satellites without this or any kind of deorbit accelerator do not get clearance for launch anymore.)

Clean Space Days der ESA im Oktober: ADEO aus dem Hause HPS im Fokus

In 2024, the ESA’s Clean Space Team once again invited participants to the continuation of the past Clean Space Days.
The four-day event will focus on progress in the areas of eco-design, zero debris and in-orbit maintenance.
The calendar of presentations in 2024 will highlight these topics, among others:

• Life cycle assessment for space activities
• Deorbit technologies
• Debris disposal
• Disturbance-free skies for astronomy
• IOS missions
• Circular economy for space travel

While some presentations tended to highlight ideas and technical concepts in statu nascendi, HPS manager Frank Hoffmann presented the ADEO product family, which is already successful on the European and, more recently, North American markets: Deorbit sail technology for automatic self-disposal of the satellite at the end of the mission.
The ADEO system offers a suitably customized solution for every class of spacecraft, whether as a “Pico” (1-20 kg), “Cube” (5-50 kg), “Nano” (20-250 kg), “Medium” (100-700 kg) or even “Large” (500-1500 kg). To ensure that satellite manufacturers are supplied without delay, all orders are handled by HPS directly from series production wherever possible.

Due to the fact that the requirement to carry a suitable disposal system such as ADEO is a prerequisite for launch authorization for practically all satellites from October 2024, longer delivery times are possible and can be largely avoided by ordering early.

The Clean Space Days will come to an end at the end of the week, but the saying “after the event is before the event” also applies to this successful European space event.

ADEO Pico: The smallest dragsail gains a foothold in the largest market

Deorbit Technology from HPS

With the ink now drying under the contract for a PICO-class satellite deorbit device from the ADEO dragsail family of HPS, the Munich-based space technology company is now also setting foot on North American soil: After careful consideration of the alternatives, the Canadian company StarSpec Technologies decided in favor of the system for integration on their InspireSAT 12U ADCS MVP satellite, to be launched in 2026.

The ADEO-P was purchased at the beginning of July. The integration will be carried out by the experts in 2025. The satellite is planned to be launched in 2026 aboard a Falcon9 as part of the Transporter-17 SmallSat Rideshire mission from the Vandenburg Space Force Base in the USA. At the end of the mission, the dragsail will be deployed to a size of 1.4 m2 and automatically dispose of the satellite within the now obligatory period of less than five years. The satellite will burn up in the atmosphere without leaving any residue.

This initiative promotes StarSpec’s high precision space-qualified ADCS components, including sub-arcsecond precision star cameras, cogless reaction wheels, and ultra-high-bandwidth controllers, providing 100x the precision and imaging quality for LEO imaging satellite.

Jason Brown, Mechanical & Technology Lead, commented on the key factors leading to the selection of the ADEO-P for InspireSAT: “A primary mandate of InspireSAT is to provide high performance in-orbit capabilities in a way that does not compromise and strongly maintains the continued and future utility of LEO. We are delighted to have HPS, a proven high-tech specialist in the international space industry, at our side, allowing StarSpec Technologies to maintain its sustainable and orbit-conscious approach to space in a way that maintains focus on the successful demonstration of our transformative state-of-the-art ADCS. Thanks HPS!”

HPS CEO: “Wishing my namesake a happy return home”

As a rule, the purpose of a satellite, be it scientific or commercial, is the focus of interest. However, there are also a few exceptions that confirm this rule. One of these is the recently launched flight of an inconspicuous 18-kilo box with a Falcon 9 from SpaceX to a low target orbit at an altitude of 510 kilometers. The name: ERNST – abbreviation for “Experimental Space Application of Nano-Satellite Technology”. Its mission: to use infrared detectors from space to detect where in the world civilian or military rockets are being launched as they fly over the earth based on the hot radiation of combustion gases – and which target they are probably aiming for. This type of technology has long been standard in the USA in the technical instruments for the nation’s fourth branch of the armed forces after the army, air force and navy, the “Space Forces”; in Europe, research in this area is still in its infancy by comparison, which is why the ERNST mission represents an important milestone for Germany.

This application-related research purpose of ERNST is still at a highly experimental early stage, but the renowned Fraunhofer Institute in Freiburg is relying on tried and tested principles to avoid space debris: a braking system with a deployable sail for accelerated return at the end of the approximately three-year mission is also on board. This is a version customized by the Fraunhofer Institute for theERNST mini-satellite. HPS collaborated with Fraunhofer on the sail almost ten years ago as part of a master’s thesis and provided support. HPS is now a pioneer of the technology and currently the world’s only commercial supplier of flight-tested automatic brake sails of the so-called ADEO family, with a total of 5 different product versions for all size classes of LEO satellites. ADEO braking sails are currently becoming standard equipment, because from fall 2024 at the latest, no satellite will be transported into space by the de facto monopoly provider SpaceX without such on-board technology for accelerated return under the new FCC regulations after the end of the mission.

“After a certain period of familiarization with the new legal situation, the run on ADEO brake sails is now in full swing. Customers in North America have also built up a great deal of trust in ADEO and HPS; the fact that HPS with ADEO occupies the lone top position in the NASA technology report on deorbit technologies is certainly helpful here. In this respect, we are naturally extremely pleased that, in addition to our commercial system on the market, we are now also securing further points for product trust and popularity through our collaboration with one of the world’s most famous German research institutes. That’s why, for once, I don’t see the operational research mission as the highlight here, but rather its end, and I wish my namesake a happy journey home,” comments Ernst K. Pfeiffer, CEO of HPS.

ESA: 1 million for product innovation by HPS, AAC and DLR

ESA’s GSTP program is one of the European Space Agency’s most important instruments for promoting new technologies, particularly those generated by SMEs. The program also enjoys high priority in the overall ESA portfolio at the German space agency; the corresponding financial resources now also enable the launch of a new sub-program called “Product Initiative”. With the signing of the contract on August 7, 2024, ESA and HPS as the main contractor gave the go-ahead for the first technology project in this category.

It took just over six months from the idea to the signing of the contract; the funding amount is one million euros. The Munich-based space technology company HPS and its long-standing partner, Vienna-based Aerospace & Advanced Composites GmbH, are contributing 20 percent of their own funds, while the DLR Institute of Space Systems in Bremen is also on board on the research side. Over the next 24 months, highly innovative films (working name “ProFilm”) will be developed in various thicknesses and surface configurations and for large-area applications, which are characterized by two special features in particular:

• they are resistant to the chemically aggressive residual oxygen molecules (ATOX-resistant) and are therefore perfectly suited for use in particular in the highly frequented low earth orbit LEO area,
• Special derivatives are invisible or non-reflective.

In addition to use as thermal insulation for satellites, this also results in innovative applications as invisible brake sails as a further development of the HPS ADEO product range for deorbiting decommissioned satellites.

In this way, they serve four strategic goals of European space:

• Securing technological independence from other major spacefaring nations that have already made progress in this area
• Support European manufacturers of spacecraft and satellites, for whom maximum physical protection is an element of the competitiveness of their products
• Avoidance of astronomy-hostile light pollution in space through non-reflective surfaces on dragsails and thermal insulation such as MLIs and SLIs. There are also plans to use them for solar panels and radiators.

The ideas go as far as deployable structures that could make entire satellites invisible with ProFilm.

HPS CEO Ernst K. Pfeiffer is enthusiastic about the start of the project: “The innovation processes that have now been initiated will result in highly exciting products – the cooperation with our partners, DLR in the north and AAC GmbH in the south, alone is a guarantee of this. Above all, however, this premiere of ESA’s new GSTP sub-programme shows how quickly and effectively the European space agency can identify, accept and master technical challenges. This is exactly what European space travel needs, and this is exactly what innovation drivers from the ranks of SMEs need in particular.”

ESA Leads the Way: Rapid Implementation of the Zero Debris Charter

Sustainability in space travel has also been an issue for the European Space Agency ESA for years. However, only a few months passed between the decision to adopt a Zero Debris Charter and its implementation.

Keynote speaker ESA Director General Josef Aschbacher also saw this as a sign that the time is finally ripe for concrete steps instead of pure symbolism, especially as ESA itself has provided significant impetus for the development of the two main technologies on the way to “Zero Debris”: firstly, ways of removing scrap from space, but above all, equipping satellites with deorbit technology from the outset so that no more waste is produced after the end of the mission.

ADEO Drag Sail: The Key to Sustainable Spaceflight

The ADEO brake sail, which is now available as an entire product family for all sizes of LEO satellites from HPS series production, stands for this. In addition to grants and support from ESA, DLR and Bavaria, HPS CEO Ernst K. Pfeiffer also invested a lot of the company’s own money in the project, always firmly convinced that the hour of ADEO would come sooner or later – and if a little later, then all the more powerfully.

It was exactly the same when, in mid-2023, the ESA set the new rule of a deorbit maximum of 5 years for ESA-funded missions instead of the previous 25 years, and, accordingly, LEO satellites without ADEO (or similar) will no longer be launched at all from October 2024, as SpaceX, for example, makes clear in its conditions of carriage in accordance with FCC regulations.

Historic Moment: 12 Nations Sign the Zero Debris Charter

The Charter was signed in Brussels on May 22 by 12 countries, including Germany. Since then, over 100 organizations, companies and entrepreneurs have been waiting for their cue to sign.

The ILA 2024 marks a very important stage on this path towards the sustainability of European space travel and sets an example for companies on other continents.

Update on ADEO´s Performance

After 487 days of approachflight towards Earth, ADEO-N2 on the ION SCV 3 test satellite continues to sail on a record course without even a scratch: the current position has been reached in a threefold shorter time of the ADEO deorbit compared to the classic missions, whose data are subject to the prediction algorithms.

Expected touchdown at the edge of the Earth’s atmosphere: April 2025.
This is reported by the two mission managers, D-Orbit, Rome (satellite) and HPS, Munich (brake sail).

ADEO L1 “ready for lift-off”: World’s largest operational brake sail for the disposal of space debris successfully tested

HPS completes the ADEO sail fleet with its first largest version under the version named L1. Its 25 square meters of sail area unfolded successfully deployed on Monday, 4th of December 2023 in a final ground test after a complete completed PFM qualification campaign. This included vibration tests in all axes as well as tests under thermal vacuum, including hot and cold firing tests (tests to verify the deployment release mechanisms under extreme temperatures). The tests were carried out under responsibility of HPS Munich at the facilities of the DLR Institute of Space Systems in Bremen – a prime example of cooperation between industry and research & development. This final and most important test enjoyed great interest from the media (including SAT1, RTL, NTV, DPA) covering the 20-minute deflation process and interviewing the enthusiastic project team of HPS and DLR. Links to the articles and television videos can be found HERE.

This test is also a success of ESA’s GSTP program, which significantly supported the development of ADEO-L1 financially and technically. Technology programs in general are essential for independent SMEs in the space industry and their products on the way to market readiness and worldwide series sales.

The ADEO brake sails deploy after the end of the satellite’s mission and brace themselves against the resistance of the atmosphere that still prevails in orbits up to an altitude of just under one thousand kilometers. This deployment immediately leads to a drastic reduction of the speed of the satellite and the entire package sets off on its accelerated descent towards the earth’s atmosphere, where it then burns up in the frictional heat of up to two thousand degrees Celsius. The entire return process takes even significantly less time than the latest guidelines prescribe. Until recently, the process could take up to twenty-five years, while it must now be completed within five years. And, to ensure that operators follow the rules, launch service providers such as SpaceX no longer even take satellites into space if they are not equipped with the appropriate return technology from the outset.

The Munich-based space-tech company HPS had this development in mind more than ten years ago, when no one else was really thinking about ways to avoid space debris. With great support from the space agencies ESA and DLR, the DLR institutes in Bremen and Braunschweig, the companies DSI, Bremen, and formerly HTS, Coswig, plus a seven-digit-investment of HPS, the company´s highly committed young team of experts has created an entire product family under the generic name ADEO, from the smallest versions ADEO-P (Pico), ADEO-C (Cube) and ADEO-N(Nano), ADEO-M (Medium) and the latest member of the group, ADEO-L (Large). The development master plan not only extends even further to possible ADEO variants with up to 100 square meters of braking surface, but also leaves enough room for derivatives with completely different applications, such as the monitoring of space debris smaller than1 cm directly in space.

In its largest flight-ready version to date, L1, ADEO has a take-off weight of 10 kg at dimensions of 43 cm x 43 cm x 25 cm; in contrast to the smaller versions, this unit also requires its own power supply for motor-controlled deployment of the masts and sails. ADEO-L1 generally fits perfectly on satellites up to the 1,500 kilo class.

In the first quarter of next year, ADEO-L1 will be integrated onto a satellite of the Belgian company Redwire for its first test flight at the end of 2024/beginning of 2025 as part of a EU program, while the versions ADEO-N1 and ADEO-N2 have already passed their baptism of fire in space. Approaching the fiery finale is currently ADEO-N2, deployed in December 2022. Since then, it has already lowered its satellite from an orbital altitude of 510 km to 460 kilometers in only 12 months without the aid of any fuel or attitude control. Expected “arrival” in a completely burnt-up state: mid2025 – and thus even around five times faster than without sails and twice as fast as prescribed.

ADEO-L1 will master this path of final in-orbit verification just as safely, company boss Dr.-Ing. Ernst K. Pfeiffer is certain. As with the other versions, it will then go straight into series production for which the company has special production facilities at its Munich and Bucharest sites.

Space sails from the ADEO series enable legal launch and disposal of satellites

As part of the National Program for Space and Innovation and based on the decision of the Budget Committee in November 2022, the German Space Agency launched a competition for promising space innovations. The winner can expect a fully organized and financed demonstration flight with launch by 31.12.2025. On Thursday, 23 November 2023, the Federal Government’s Space Coordinator, Dr Anna Christmann, selected Munich-based space technology company HPS as the winner of the competition in the small satellite payload category with its ADEO-Cube space sail version at the 2023 Small Satellite Conference. The ADEO product family is designed as a series with different model types (Pico, Cube, Nano, Medium, Large), with which all satellites from the Cubesats to the larger representatives with 1.5 tons (class “M”) are automatically removed from low Earth orbit (LEO) and disposed of at the end of the mission. This so-called “deorbiting” with the ADEO braking sail not only fulfills, but even undercuts the maximum duration of 5 years that will apply from October 2024 instead of the 25-year guideline that has been in place since the 1960s. Quite simply, this means that no satellite will soon be accepted for launch without special on-board technology, such as the appropriate space sail from HPS’s ADEO series, if it cannot otherwise be legally disposed of. Since SpaceX, for example, as the leading launch service provider, will be introducing this rule from October 2024, it will apply to practically all future satellites, including those that are already in the design and manufacturing phase today.
As HPS CEO Ernst K.Pfeiffer, there is still only one alternative to ADEO, but it “is chemical, expensive and – in the case of a damaged satellite – inoperable”, the passionate aerospace engineer states about the market position of the ADEO space sail: “ADEO is currently the cheapest, most reliable and cleanest solution for legal deorbiting on the global market, available in all classes thanks to series production at HPS Bucharest and HPS Munich, and highly competitive in the hotly contested commercial market for satellite technology.We at HPS, especially our development team, are all very pleased that our sustainable technology has been recognized by the Small Satellite Competition at the highest level.”
