OHB Space UK Secures €24m EnVision Venus Contract: A Milestone for British Space Manufacturing

OHB Space UK has announced a significant €24 million contract with the European Space Agency (ESA) to assemble and test critical spacecraft components for the EnVision mission to Venus. The award, delivered on the company's first anniversary in the UK market, will establish a new cleanroom facility in Bristol and create approximately 100 highly skilled jobs across engineering, assembly, testing, and project management roles.

The contract represents a watershed moment for UK space manufacturing and signals growing confidence in British capabilities to deliver complex, mission-critical hardware for flagship European space exploration programmes. EnVision, scheduled for launch in the early 2030s, will conduct the most detailed atmospheric and surface study of Venus ever undertaken, with profound implications for understanding planetary climate evolution and habitability.

The EnVision Mission: Exploring Humanity's Hottest Neighbour

Venus remains one of the solar system's most extreme and least-explored environments. With surface temperatures exceeding 460°C and atmospheric pressures 92 times greater than Earth's, the planet presents extraordinary engineering challenges. EnVision will deploy a suite of instruments to understand why Venus evolved so differently from Earth—a crucial question for understanding planetary habitability and climate dynamics across the universe.

The mission comprises three primary science payloads: a high-resolution synthetic aperture radar (SAR) for surface mapping, a visible and near-infrared spectrometer (VNIS) for compositional analysis, and an ultraviolet/infrared spectrometer (UVI) for atmospheric characterisation. Thales Alenia Space, the prime contractor for the EnVision orbiter, selected OHB Space UK to manage the critical spacecraft bus assembly and comprehensive qualification testing phase.

The spacecraft bus—the vehicle's structural and functional backbone—must withstand extreme thermal environments, high-energy solar radiation, and the mission's seven-year interplanetary cruise. OHB Space UK's role encompasses the physical assembly of the spacecraft structure, integration of thermal control systems, electrical harness installation, and rigorous qualification testing to validate every system against mission requirements.

OHB Space UK: Building British Capability in Deep Space Hardware

OHB Space UK, part of the international OHB Group headquartered in Bremen, Germany, established its Bristol operations in May 2025. The company selected Bristol specifically for its existing space engineering cluster, proximity to the University of Bristol's space research facilities, and the broader South West England aerospace ecosystem spanning Bristol Aerospace, Rolls-Royce Defence, and emerging satellite technology startups.

The Bristol site will house a new ISO 8 cleanroom facility—representing one of the UK's largest purpose-built satellite assembly environments—capable of handling large spacecraft structures and integration operations. The facility design accommodates both current EnVision requirements and future European Space Agency and commercial deep space missions, positioning OHB Space UK as a key node in European space manufacturing networks.
