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.

German space agency chief Dr. Walther Pelzer and DLR delegation focus on visit to HPS Group

During the traditional DLR delegation round on the opening day of the Space Tech Expo in Bremen, the head of the German Space Agency at DLR, Dr. Walther Pelzer, focused his attention on SMEs in the German space industry. Special attention was paid to the innovation forge HPS. And it was represented in groups: with HPS Germany (Munich), HPS Romania (Bucharest) and the joint venture company HPtex (Münchberg, Germany).

With reference to pioneering antenna projects such as HERA and EUCLID, company boss Ernst K. Pfeiffer emphasized the leading position Germany has gained in special antennas for space missions. HPS is also positioning itself as a leader in the commercial sector with the successful ADEO braking sail project, which ensures compliance with the new 5-year rule for satellite deorbiting and thus keeps the satellites ready for launch.

In his role as spokesman for German space SMEs, Ernst Pfeiffer also took this opportunity to emphasize the enormous importance of the DLR and ESA’s capability-enhancing technology programmes for SMEs as the innovation backbone of the industry. According to Pfeiffer, the precise promotion of the technological capabilities of SMEs via dedicated competition areas reserved for SMEs is irreplaceable.

Live demonstrations, e.g. of a functional model of the ADEO brake sail or a scaled model of a deployable large antenna reflector, supplemented by product demonstrations from HPS-Romania (e.g. radiator) and from HPtex’s MESH production (e.g. Ka-band mesh sample for use in the Copernicus mission CIMR) rounded off the visit program.

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.”

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).
