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!”

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.”

ADEO deorbit sail system from HPS

Space-related technologies should be clean and sustainable, because only then access to space will remain possible for future generations. This topic, which is currently a top priority of space policy, has led to a number of technical solutions which are now available on the market, with the ADEO deorbit system from HPS leading the way. Being recognized even by NASA, the ADEO dragsails ensure already before launch that satellites will not turn into space debris at the „end-of-business“. Instead, they re-enter the Earth’s atmosphere.

The European Space Agency ESA, as well as its national counterpart DLR and the Bavarian Ministry of Economic Affairs, has consistently supported the twelve years of development of this product by HPS. The sharp increase in demand from customers, particularly in the CubeSat and SmallSat sector from Europe, but also from North America and even Asia, is driven by the simple fact that both ESA, for European launches, and the FCC, for American launches, now demand on-board systems to be able to deorbit a satellite in just 5 years instead of the previous 25 years. Also SpaceX confirms that no more satellites will be launched without complying to this requirement.

With the ADEO variants “Pico”, “Cube”, “Nano”, “Medium” and “Large”, HPS meets the market demand for all sizes of LEO satellites in orbits between 300 and 900 kilometers. All variants are already in production, with manufacturing at the HPS production sites in Munich (Germany) and Bucharest (Romania) which are closely working together. Nevertheless, HPS and the technical ADEO experts at ESA have identified a number of optimization and expansion opportunities in order to urgently increase the pace of the series production and in response to the increasing price pressure of the New Space scene. The company is now raising the required funds for the implementation of these opportunities in the short term, using co-financing of 1.2 million euros signed by ESA on June 28, 2024.

ESA-Director Dietmar Pilz for Technology, Engineering and Quality in a videocon on July 1st: „my best wishes for this important technology development.“

HPS CEO Ernst K. Pfeiffer: “As a company, we are very pleased about the trust and continuous support from the European Space Agency, and therefore indirectly also from the German Ministry of Economic Affairs. However, this is at least as much a reason for joy for all those who, thanks to its technology programs such as GSTP, would like to see Europe in a leading role in the development of components for space technology and -transport, especially in the commercially so important LEO and MEO supplier market.

ESA’s priorities here are not only clear, but are also being consistently implemented. One milestone was the recent signing of the Zero Debris Charter in Berlin. The upcoming optimization of series production and the enhancement of our ADEO product portfolio, while maintaining the same level of quality and reliability, will effectively help to face the upcoming peaks in global orders, including those received very late, and thus still enable the launch of these satellites. We shareholders see our own funds, in the 7-digit range over the years, on the one hand as an investment in a strong future for HPS, and on the other hand as our moral obligation to make a contribution to the sustainable use of space.”

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).

HPS with ADEO in top position in NASA’s technology report

Since its inception, the U.S. space agency NASA has been the primary driver of progress in aerospace technology. NASA’s Scientific and Technical Information (STI) program plays a key role in ensuring that NASA maintains this important role. Its Technical Reports Server contains one of the largest collections of aerospace science STI in the world, including “Technical Publications” on critical research and achievements of lasting value.

Focus on deorbit technologies

The aim of the latest publication, published in February 2024, on groundbreaking technologies, particularly in the field of small satellites, is, among other things, to present the world’s leading deorbit technologies, which can be used to technically implement the new regulation on the disposal of LEO satellites, which has been sharply limited from 25 to 5 years in both the USA and Europe. In its evaluation criteria for technologies, NASA is primarily guided by the TRL standard of the respective products and also pays great attention to the scalability achieved.

ADEO has it all: top values up to TRL-9, scalability and flight successes

According to NASA, the deployable brake sail system ADEO from HPS occupies the leading position on the global market in the category of passive deorbit systems. This is because ADEO not only offers technological maturity up to the peak value of TRL-9, but also a successful flight heritage and is also prepared for equipping various small satellite formats thanks to the HPS series production of an entire product family. This broad protection of HPS’s leading position with ADEO has been widely recognized by NASA – despite the fact that it is a competitor with several projects in this field:

“The Drag Augmentation Deorbiting System (ADEO) is a drag sail developed by the German company High Performance Space Structure Systems (HPS). The sail is scalable and HPS has already launched a number of missions with different configurations up to TRL 9. The ADEO-N series is tailored for small satellite missions of 20-250 kg, while the ADEO-M and ADEO-L series are designed for larger missions of 100-700 kg and 500-1500 kg respectively. The ADEO-N series corresponds to a sail size of 5±2 m2, while ADEO-M covers areas of 15 ± 5 m2. There are also smaller versions, especially for picosatellites (ADEO-P) and CubeSats (ADEO-C), and the possibility to configure the sail size according to customer requirements. Various missions have already tested the ADEO-N product family. The NABEO-1 was launched on a Rocket Lab Electron rocket kick stage in 2018. The sail was deployed just 90 minutes after launch. There was a problem measuring whether the drag sail was initially deployed, but visual ground observations confirmed successful deployment and performance. At the end of December 2022, the ADEO-N2 sail was launched into space by the ION-2 spacecraft carrier of the Italian launch service provider D-Orbit. The successful deployment was recorded by the ION carrier’s on-board camera.”

ADEO – Deorbit technology as a prerequisite for launch authorization

With this presentation in one of the most important technology documentations of the US space agency NASA, HPS with ADEO becomes a highly visible beacon in the worldwide field of passive deorbit systems for all satellites that have to comply with the new 5-year deorbit requirement in order to be approved for launch by American or European launchers

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.”

ESA´s “Zero Debris Charter” finalized – HPS among the first to sign

Initiated by ESA´s office for “Strategy and Transformation” a considerable group of European space companies, including HPS, got together in order to jointly draft and now implement this continent´s set of rules for sustainable use of space. HPS is one of the first companies to sign the document on November 7th, 2023. Though legally non-binding, the “Zero Debris Charter” aims at putting an end to the inconsiderate and irresponsible pollution of space with tech-junk. In detail, the Charter clearly names the following targets:

1. The probability of space debris generation through collisions and break-ups should remain below 1 in 1,000 per object during the entire orbital lifetime. A suitable aggregate probability threshold for constellations of satellites in the low Earth orbit region should be identified.
2. Timely clearance of low Earth orbit and geostationary Earth orbit regions should be achieved with a probability of success of at least 99% after end of mission, including through external means when necessary.
3. The casualty risk from re-entering objects should remain significantly lower than 1 in 10,000, striving towards zero casualty. A suitable aggregate risk threshold for constellations of satellites in the low Earth orbit region should be identified.
4. Routine and transparent information sharing should be facilitated and active participation in strengthening global space traffic coordination mechanisms should be encouraged.
5. Access to timely and accurate data on space objects down to a size of 5 cm or smaller in low Earth orbit and 20 cm or smaller in geostationary Earth orbit should be improved to enhance decision making capabilities for collision avoidance.*

Ernst K. Pfeiffer, CEO of HPS at the signature ceremony: “In our days now space is rapidly developing into the most important resource for the implementation of new technologies shaping our future on Earth. All efforts to preserve space from the beginning are therefore nothing less than efforts to preserve the fundamental conditions of life and its prosperity for humankind´s generations to come.”
