Welcome to SpaceTech Ireland — a fast, Ireland-focused read on the space economy.

This week: Réaltra signals an investment round as the Clonshaugh company's video telemetry flies on a second Amazon Leo launch from Kourou next Tuesday. A Brussels rule change could reshape access to ESA and EU funding for equity-backed Irish scale-ups. Galway's Mbryonics puts a production timetable on its 40,000 sq ft Shannon facility. And ESA opens the door to industrial-scale satellite manufacturing.

Réaltra Space Systems Engineering’s video telemetry flies on a second Amazon Leo launch from Kourou next Tuesday, as the Clonshaugh company works through an ArianeGroup follow-on order signed last October.

Réaltra designed and delivered the Ariane 6 video telemetry system, VIKI, under contract to ArianeGroup. It has flown on every Ariane 6 since the maiden flight in July 2024. The October order added a further seven units, worth €1.5M.

The company had revenue of €3.5M last year and employs 20 people. Founder Danny Gleeson told the Business Post in March that Réaltra is preparing to raise investment to scale the business.

"We're at the stage where we have products that are proven and have a global market to target," he said. "We can scale into that but to scale, we need investment." He expects revenue to grow by 10 per cent in 2026.

Tuesday's flight is the second of the heavy-lift Ariane 64 - the four-booster version of the rocket - and the second of 18 launches Arianespace has under contract with Amazon. The 32 satellites arrived in Kourou in mid-March. The Ariane 6 stages travelled from Europe aboard the part-sail-powered cargo ship Canopée and are being integrated at the spaceport this week.

Lift-off is set for a window between 09:51 and 10:39 Irish time on Tuesday 28 April.

A quiet technical revision in Brussels could matter a lot for Irish space companies. The European Commission's consultation on the revised General Block Exemption Regulation (GBER) - the rulebook that decides when EU states can support companies without having to clear it with Brussels first - closes on 23 April.

At issue is an existing definition called "Undertaking in Difficulty" (UiD). If a company meets the definition, it is classed as financially distressed and blocked from a long list of public funding, including ESA contracts routed through national agencies, Horizon Europe grants, and Enterprise Ireland supports.

The test compares accumulated losses to share capital - which catches well-funded deep-tech scale-ups that have raised equity and spent it on R&D. In other words, the business model of many Irish space companies on the scale-up track.

Dutch industry body Techleap has publicly submitted recommendations, including replacing the equity capital ratio with a broader solvency test, recognising convertible loans and public financing like EIB in the assessment, and extending the enterprise exemption from 10 to at least 15 years. SMART Photonics CEO Johan Feenstra has called on European deep-tech scale-ups to back the submission.

No Irish submission has been publicly flagged at time of writing. The consultation closes Thursday.

ECSECO, the ESA-linked industry network for Europe's civil-security and defence space economy, is running its first Summer School at Kozminski University in Warsaw from 22 to 24 June.

The three-day programme covers space commercialisation, dual-use technology, cyber resilience and the growing overlap between civil space and defence markets. Speakers include ESA staff, the Polish Ministry of Defence, and Finnish radar operator Iceye.

ESA Academy is funding up to five scholarships for third-level students from ESA member states, Ireland included. The package covers registration, up to €350 in travel and up to €225 for accommodation. Priority goes to students with less than two years' professional experience who have not previously received ESA Education Office support.

Applications close 17 May.

Galway's Mbryonics has put a production timetable on its Shannon factory build-out, confirming on Monday that the 40,000 sq ft Photon-2 facility is targeting thousands of optical terminals a year by 2027.

That is a tenfold step up from its Photon-1 facility in Dangan, Galway, which opened last September with an initial capacity of 500 units a year. The company has previously put the Shannon capacity at more than 5,000 units.

The announcement ties the Photon-2 build-out to Mbryonics' role in ESA's €18.6 million HydRON Element 3 contract, awarded on 14 April and covered here last week. Canada's Kepler Communications is prime contractor; Mbryonics will supply its StarCom optical terminal alongside hardware from Germany's TESAT and Lithuania's Astrolight, with space situational awareness payloads from Germany's Vyoma.

Mbryonics leased Block R in Shannon Free Zone last September as its future Photon-2 site but had not previously put a production timetable on it.

“The internet was built by making different networks talk to each other, and that's exactly what we're enabling in space,” CEO John Mackey said. “Just as we demonstrated in DARPA Space BACN, this ESA award allows us to showcase how our laser communication technologies enable satellites from different providers to communicate seamlessly in orbit.”

ESA has opened a call for industry input on a major push to industrialise production of mid-size satellites for low Earth orbit constellations. The Request for Information for the M-IND initiative - Mid-size LEO Satellite INDustrialisation - is run through ESA's General Support Technology Programme and targets satellites in the 100–500 kg range.

In plain terms, ESA wants Europe to move from building satellites one at a time to producing them more like an assembly line. The wider campaign targets a 90% cut in spacecraft development time and a 10x improvement in cost efficiency.

The agency is looking for ideas across avionics, power systems, communications, electric propulsion and payload modules - areas where several Irish companies already have strong capabilities. M-IND is one strand of a broader ESA initiative called SMART-IND!, aimed at preparing European industry for large-scale constellation programmes including IRIS², LEO-PNT and the new European Resilience from Space (ERS) Earth observation constellation.

Submissions go through ESA's Open Space Innovation Platform (OSIP), the agency's online front door for new ideas. Companies register, submit an outline proposal against the open call, and if ESA is interested, they are invited to develop a full proposal under GSTP Building Blocks. From there, successful concepts can progress to funded work under GSTP, ARTES or NAVISP.

Deadline: 15 May 2026. RFI and submission guidelines at ESA's OSIP campaign page.

🚀 ESA Phi-Lab Ireland manager Rob Conway-Kenny has been appointed as one of the first three Ambassadors of the European Centre for Space Economy and Commerce (ECSECO), bringing Ireland into the leadership of ESA's community for space economy and commerce. Ireland’s space sector has grown sharply in the past three years. A seat at the ECSECO table gives that activity a direct channel into the wider European conversation on where the money, policy and talent are going.

🚀 Europe's reusable spaceplane takes shape: A full-size test model of ESA's Space Rider has been completed at a research centre in Capua, southern Italy, marking a significant step toward the vehicle's first flight, currently scheduled for early 2028. Space Rider is designed to launch into low Earth orbit, spend up to two months running experiments - in areas like pharmaceuticals, materials science, and satellite deployment - then glide back to Earth and land on a runway, ready to be refurbished and flown again.

ATMOS Space Cargo - €25.7M Series A - orbital return fleet - The Germany company raised €25.7 million in a Series A round co-led by Balnord and Expansion Ventures, with Keen Defence and Security joining as a new investor. Existing backers OTB Ventures, High-Tech Gründerfonds, APEX Ventures and Seraphim participated, alongside the European Innovation Council through its Accelerator programme. The funding will support a three-vehicle PHOENIX 2 fleet, a new unit called ATMOS WORKS aimed at European government and defence customers, and early development of PHOENIX 3, a larger vehicle designed to return roughly one tonne of payload from orbit.

The company is building an independent way to bring payloads back from low Earth orbit, relevant for in-orbit manufacturing, materials research and sovereign return of sensitive hardware or data. CEO Sebastian Klaus describes the architecture as "commercial, institutional and defence-capable, in parallel." ATMOS flew its PHOENIX 1 demonstrator on SpaceX's Bandwagon-3 mission in April 2025.

ESA Sustainable Wetlands kick-start: up to €75,000 per study, closes 15 May - The ESA Business Applications and Space Solutions programme opened this call on 30 March. It funds six-month feasibility studies for space-enabled services that help conservation bodies, local authorities and agri-environment programmes manage wetlands. Funding covers up to 75% of costs to a maximum of €75,000 per study. Relevant for Irish Earth observation and connectivity companies already working with NPWS, Teagasc or Bord na Móna restoration projects.

ESA Wildfires kick-start: up to €75,000 per study, closes 2 June - The third thematic kick-start currently open under ESA Space Solutions. Same funding terms as the wetlands and rural transport calls. Proposals sought for space-enabled services supporting wildfire prevention, detection and response. Ireland's wildfire risk profile is rising with longer dry spells, and Coillte and NPWS monitoring needs are growing - a clear hook for Irish EO and satellite communications companies with adjacent products.

PICTURE: Rocket Lab had its 87th successful Electron launch on Thursday, deploying eight small satellites for Japan’s JAXA space agency into a 540-kilometre sun-synchronous orbit from New Zealand’s Mahia Peninsula. The mission, named ‘Kakushin Rising,' is part of JAXA’s programme for Japanese universities and companies to test new space tech.
