The MICE-1 and PHASMA Greek CubeSat missions supported by the European Space Agency (ESA) have begun their in-orbit activities, a key milestone in their launch and early operations phase.

The two missions were launched into Sun Synchronous Orbit on 28 November 2025 aboard SpaceX’s Transporter-15 rideshare mission from Vandenberg Space Force Base, USA. Joining DUTHSat-2 in orbit, MICE-1 and PHASMA are part of the Greek National Small Satellite Programme implemented by ESA on behalf of the Hellenic Ministry of Digital Governance. The three missions are part of a larger endeavour to launch a total of seven Greek missions, which will culminate with four additional CubeSat missions in 2026.

The Greek IOD/IOV CubeSat programme falls under the National Recovery and Resilience Plan ‘Greece 2.0’ funded by the Recovery and Resilience Facility (RRF), a core programme of the European Union’s NextGenerationEU. The RRF aims to strengthen Greece’s technological capabilities in areas such as secure connectivity and Earth observation, while fostering the country’s presence in the global space community.

MICE-1 and PHASMA are the latest addition to this effort. The satellites are operated by PRISMA Electronics and the Libre Space Foundation respectively. During the critical launch and operations phase, both teams work to verify spacecraft health, gradually activating onboard systems. Following launch, the operators successfully established contact with all spacecrafts and verified their response to commands – enabling the teams to safely progress through the commissioning of key functions and transition towards routine operations.

The test demonstrated a complete, end—to—end remote patient experience. The user equipment located in the 5G/6G Hub at ESA’s European Centre for Space Applications and Telecommunications (ECSAT) site at the Harwell Science and Innovation Campus connected through a OneWeb satellite backhaul to the University of Glasgow’s 5G pop—network. This pop—up network enabled the team to connect to a robotic arm located at the University of Glasgow’s Loch Lomond facility, using a 5G edge breakout to optimize user plane traffic. Through this remotely controlled robotic arm, the doctor at ESA ECSAT was able to perform a dental examination of the simulated patient at Loch Lomond. The Space for 5G/6G team then dispatched a drone to deliver medication to the patient, all the while monitoring and tracking its payload over a 5G—enabled Long—Range Wide Area Network (LoRaWAN).

This seamless experience — blending terrestrial and non—terrestrial networks with robotic systems and drones while leveraging edge computing capabilities — highlights the transformative potential of integrated terrestrial and non—terrestrial connectivity for secluded areas. Where terrestrial networks are not economically viable or practical due to geographical or demographic constraints, hybrid 5G and satellite—enabled connectivity can bridge the gap and enable advanced telemedicine services. By integrating terrestrial and non—terrestrial networks, new and faster communications standards being developed by industry will help to enable stable and continuous connections worldwide.

Leveraging the potential of ubiquitous signal coverage afforded by integrated terrestrial and non—terrestrial networks, the 5G REMOTE project combines satellite connectivity with a portable 5G pop—up network that can be rapidly deployed in remote locations where only satellite coverage can reach. This hybrid solution supports critical services, such as telemedicine, by enabling new robotic and unmanned solutions that extend the reach and effectiveness of healthcare providers. For emergency situations, this technology can help provide critical care, even in geographically isolated and otherwise hard—to—reach locations. The technology can also reduce cost by removing transportation from the equation.

“This kind of reliable and flexible connectivity has potentially transformative applications for improving the wellbeing of millions of people,” said Antonio Franchi, Head of ESA’s Space for 5G/6G & Sustainable Connectivity programme. “We are combining satellite communications technology with new advances in mobile signals and robotics to unlock the full power of telemedicine and help to overcome the digital divide.”

 “Access to healthcare should not depend on postcode or proximity to a major hospital. Our team’s work with ESA demonstrates a practical pathway to bring specialist assessment and timely intervention closer to remote and rural communities,” said Professor Muhammad Imran, Head of James Watt School of Engineering at the University of Glasgow. “This was enabled by using integrated 5G and satellite connectivity (terrestrial and non—terrestrial networks) to support real—time interaction, remote examination and delivery of essentials when every minute matters.”

The DUTHSat-2 mission brings together Greek academia and industry, being led by the Democritus University of Thrace, and supported by the Athena Research Center and Greek companies Space Asics and Prisma Electronics SA. The spacecraft was assembled on site at the Democritus University of Thrace, with the design, assembly and test process guided and monitored by ESA’s Connectivity and Secure Communications.

“We are proud of this achievement, which was possible by working as one team and by sharing the same motto: Let us make this happen! We are now looking forward to the launch followed by the start of the operations,” said Frédéric Rouesnel, ESA’s Greek Connectivity RRF Project Manager.

“DUTHSat-2 is now at Vandenberg Space Launch Complex 4 with an expected launch date in a couple of weeks onboard a Falcon 9 rocket. We are excited to witness the first satellite of the Greek National Small Satellite programme delivered to the launch provider. Congratulations to both ESA and the Democritus University of Thrace and the respective teams, for managing a technicaly complex project with programmatic challenges. Greece is climbing the steep learning curve of accessing space in order to glean the benefits of the new space economy. We are all proud to be part of the endeavour and wish the best for this as well all upcoming missions,” said Prof. Konstantinos Karatzalos, Secretary General of Telecommunications and Posts.

ESA, Telesat and the Science and Technology Facilities Council’s (STFC) RAL Space have reported a groundbreaking milestone in telecommunications technology, successfully establishing a Q-Band (38-39 GHz) link over LEO, between the RAL Space Chilbolton Observatory and the Telesat LEO 3 demonstration satellite.

The achievement was performed under a Memorandum of Understanding signed in early 2024 between Telesat and ESA, and showcases the newest milestone in the partnership, building on the world-first 5G NTN demonstration in December 2024.  

This project was funded as an ARTES Advanced Technology activity under the Space for 5G/6G and Sustainable Connectivity programme line, supported by the UK Space Agency. The resulting achievement represents a significant leap forward in satellite communication technologies, validating the performance of millimetre-wave Q-Band communications in LEO. 

The team, brought together experts from the ESA Connectivity and Secure Communications, and Technology, Engineering and Quality directorates, and also marked the first mission for ESA Technology’s mobile laboratory van which will support future campaigns, and leveraged expertise from the Technology directorate’s Wave Interaction and Propagation section. 

A Q-Band receiver developed by RAL Space was mounted on Chilbolton Observatory’s large 25m dish, which is normally used as a LEO satellite tracking radar. The team at the observatory used this radar tracking capability to monitor the state of the satellite and its orbit effectively during each pass. The team established a stable link with a collocated Ka-Band uplink antenna to the Telesat LEO 3 satellite, and maintained connectivity from approximately 15° elevation to a maximum of 80°.  The Telesat LEO 3 satellite also provided frequency up-conversion to Q-Band, amplification and retransmission to ground. The Telesat satellite station transmitted a DVBs signal with fixed QPSK ¼ modulation and fixed power, with the ESA modem locked with a margin of up to 13 dB and Es/N0 of up to 10.66 dB. 

In addition, thanks to a Software Defined Radio (SDR) available at the receiver, the RAL scientists and engineers collected critical wave propagation data for the entire satellite visibility periods. This allows us to evaluate the characteristics of atmospheric Q-Band propagation channel,. including in-excess attenuation, total attenuation and its components, scintillation and Doppler effect. Such propagation experiments are carried out in collaboration with Joanneum Research, Austria, for their experience with LEO measurements gained in the ESA ARTES W-Cube project. 

By studying Q-band and higher frequency communications, ESA is driving a fundamental shift in how satellite communication systems are conceived. This follows on from the legacy of Alphasat TDP5 and the Aldo Paraboni experiment, where ESA and a Thales Alenia Space-led Italian consortium, conducted a similar technological demonstration in geostationary (GEO) orbit. As the satellite communications market moves further into leveraging LEO capabilities, this latest demonstration showcases ESA’s commitment to driving European industry capabilities in an increasingly competitive global market. 

Demonstrations like this support a potential, more intensive use of Q-Band by LEO constellations, which, in turn, brings several critical advantages such as considerably smaller antennas, making it particularly attractive for aerial and land-mobile satellite communications. The Q-Band over LEO is also attractive for aerial (drone/HAPS) relay backhaul using the 5G New Radio (NR) standard, which is a novel approach for 5G networks. Additionally, Q-Band may be an attractive option for downlinking LEO traffic to gateways, freeing up Ku- and Ka-Band spectrum for additional user traffic. 

The most significant implication is the potential for consumers and business to access a much wider frequency spectrum. Satellite and terrestrial networks convergence is unlocking new innovations which will help connect communities, support emergency response systems, and enabling new possibilities for 5G and future 6G communications across the economy and society. 

Fabrizio De Paolis, ESA’s 5G/6G Implementation Manager, said: “We’re proud to be building truly world-leading connectivity capabilities in Europe and Canada, demonstrations like this showcase how ESA is working hand-in-hand with our industry partners. driving our competitiveness on the global scale.” 

Antonio Franchi, ESA’s Head of Space for 5G/6G and Sustainable Connectivity programme line, said: “We are proud to see our collaboration with Telesat – and now RAL Space – continue to grow, unlocking new opportunities through higher frequency communications. This latest demonstration, supported by the dedicated teams from ESA, is a key step toward enabling new 5G and 6G NTN capabilities. It highlights how our Member States are driving innovation to meet both market needs and societal challenges. Congratulations once again to the entire team!” 

Alberto Ginesi, Head of the Telecom Systems and Techniques Section of the Directorate of Technology, Engineering, and Quality, said: “The quest for higher frequency has always been at the centre of ESA R&D investigations over the last half century. This achievement represents yet another important milestone in that direction and reaffirms the role that the Agency wants to play in helping its member/supporting state industry in exploring innovative systems and technologies.” 

Antonio Martellucci, propagation engineer and Nicolas Floury Head of Wave Interaction and Propagation Directorate of Technology, Engineering, and Quality, said, “The experimental assessment of the satellite radio channel and atmospheric propagation effects at high frequencies is an essential step for the design and operation of efficient and reliable satellite services and provides the foundation for radio regulatory studies. This is made possible by the commitment to develop propagation instruments and experimental techniques in ESA programmes.” 

Mario Neri, Telesat’s Director of Spectrum Strategy, Innovation and Space Sustainability said “Telesat applauds this cooperation with ESA and RAL space. Telesat has been continuously innovating to meet the connectivity demands of the future, and the data collected from this demonstration is invaluable as we consider higher frequency bands for future expansion of the Telesat Lightspeed LEO constellation. I’d personally like to recognise and thank Telesat’s engineering professionals who supported this programme.” 

Dr Emal Rumi, Principal Research and Development Engineer at STFC RAL Space said: “We’re witnessing a shift in satellite communications as many operators move from targeting distant geostationary orbits only to increasingly including low earth orbits. This Q-band breakthrough addresses two crucial challenges – the increasing demand for high-speed data, and the rapid growth of LEO telecommunication satellites. Chilbolton Observatory has been driving telecommunication research since the 1980s, and this milestone demonstrates that our expertise in RF design and signal propagation studies is just as relevant today to support partners delivering new research, technologies, and services.”
