SSIT invests in $50m funding round for Zeno Power to advance space-ready nuclear batteries

SSIT invested £4.1m in Zeno Power's $50m Series B funding round, led by Hanaco Ventures. This new investment brought Zeno's total funding to over $70m, supporting the company's efforts to develop compact nuclear batteries that can deliver reliable, long-lasting power in extreme environments such as space, the deep ocean and polar regions. Zeno is pioneering the commercial use of radioisotope power systems based on Strontium-90, a by-product of nuclear waste. These systems are designed to operate for years without sunlight, refuelling or recharging, offering a breakthrough solution for powering critical infrastructure where traditional energy sources fail.

Voyager Technologies files for IPO, targets 2029 Starlab launch and acquires Optical Physics Company

Voyager Technologies, formerly Voyager Space, has filed for an IPO as it ramps up development of Starlab, the $2.8-3.3bn commercial space station set to launch in 2029 aboard a SpaceX Starship. With NASA as its largest customer and a growing national security portfolio now accounting for two-thirds of Q1 2025 revenue, Voyager reported $144.2m in revenue for 2024. The company holds a 67% stake in the Starlab joint venture alongside Airbus, MDA, Mitsubishi and Palantir. Voyager also acquired Optical Physics Company for $10.7m to strengthen its defence technology capabilities. [Read more]

AST SpaceMobile projects up to $75m revenue in H2 2025, taps into US defence opportunity

AST SpaceMobile has projected $50-75m in revenue in H2 2025, driven by government contracts, gateway deployments and early service income. CEO Abel Avellan noted that these revenues will help support the company's funding needs over the next three years. Avellan also stated that AST's satellites could make the company a valuable contributor to the US government's $25bn Golden Dome missile defence program, citing its unique capabilities for national security applications.

SatVu secures $6m in pre-orders despite early satellite setback

SatVu secured $6m in pre-orders for its next thermal imaging satellite, HotSat-2, following the early failure of its first satellite after six months in orbit. Despite this setback, HotSat-1 provided valuable high-resolution mid-wave infrared data that demonstrated the technology's potential to both commercial and government clients, including US defence contractors supporting the US National Geospatial-Intelligence Agency's Luno program. SatVu's sensors detect thermal signatures down to 3.5 meters, enabling detailed monitoring of infrastructure and industrial activity. Supported by a $10m insurance payout and the efforts of manufacturer Surrey Satellite Technology Ltd., a subsidiary of Airbus, to address prior issues, SatVu aims to build an eight-satellite constellation delivering daily global coverage, reinforcing its promising position in the remote sensing market.

Seraphim announced 15^th accelerator cohort

Seraphim announced the 15^th cohort of its global leading accelerator program, featuring 10 startups from five countries, including its first from Mongolia. The latest round reflects a growing trend of commercial innovation aligning with national security priorities, with participating companies tackling challenges in defence communications, satellite-enabled AI and microgravity manufacturing. Since launching in 2018, the program has supported startups that have gone on to raise over $695m in private funding. [Read more]

New report values the space industry at $944bn by 2033

A new report from Novaspace estimates that the global space economy will grow from $596bn in 2024 to $944bn by 2033, a 1.5x increase in less than a decade. The expansion is expected to be driven by wider adoption of downstream technologies such as AI and cloud computing, which are making space-based data more accessible and commercially useful. Downstream services, which include applications that leverage satellites and space infrastructure for use on Earth, already account for over half of the industry's value. In contrast, upstream activities like launch services and satellite manufacturing make up the remainder, underscoring the shift toward data-driven solutions in the sector. [Read more]

Intuitive Machines confident in lunar plans

Intuitive Machines remains confident in its lunar ambitions despite recent NASA budget adjustments. CEO Steve Altemus highlighted strong support for commercial-led Moon and Mars exploration, with no expected impact on upcoming contracts. The company is advancing its heavy cargo lander and Lunar Terrain Vehicle, launching aboard SpaceX's Falcon Heavy, with exciting contract phases anticipated in 2025. Alongside lunar efforts, Intuitive Machines is breaking ground in national security space projects, including an orbital transfer vehicle, a Texas-funded re-entry vehicle and pioneering nuclear propulsion for stealth satellites. Following valuable lessons from two 2024 landing attempts, Intuitive Machines has enhanced its technology and is on track for a third Moon landing mission in early 2026. [Read more]

China issues framework for direct-to-device satellite services

China has introduced its first regulatory framework for direct-to-device (D2D) satellite services, supporting the growth of satellite-enabled mobile and IoT connectivity. The new rules address licensing, data security and device standards, while mandating domestic data handling and real-name registration. The move mirrors global momentum in the D2D sector, following the Federal Communications Commission's similar framework in the US, and positions China to influence international standards. This development highlights growing global competition in space-based mobile communications, where companies like SpaceX, Lynk Global and SSIT portfolio companies AST SpaceMobile and Skylo are leading innovation.

ESA proposes €20bn budget as Aschbacher calls for increased European space investment

European Space Agency (ESA) Director General Josef Aschbacher has called for a major increase in European space funding, highlighting that Europe contributes just 10% of the €100bn ($112bn) spent globally by governments on space, far behind the US (60%) and China (15%). Speaking to the European Parliament, he described Europe's achievements in Earth observation and navigation as "almost a miracle" given this disparity and revealed the ESA is preparing a €20bn budget proposal for 2025-2027, an 18% increase over the €16.9bn approved in 2022. He argued that greater investment is essential to strengthen Europe's autonomy and competitiveness in the global space sector. [Read more]
