British satellite to map Earth鈥檚 forests in 3D for the first time to help combat climate change

Satellite developed by British academics and engineers set to become the first in the world to measure condition of the Earth's forests from space.

  • World鈥檚 first mission to map the world鈥檚 forests in 3D from space will use cutting edge tech to inform climate change policies and protect future generations.聽聽

  • Supports UK sector worth around 拢18.9 billion and likely to attract further investment that can grow the economy and help drive our Plan for Change.聽聽

  • Project has supported around 250 highly skilled jobs in Stevenage, bolstering UK鈥檚 52,000 strong space workforce.

This work will be crucial to helping us understand how tropical forests are changing so we can protect future generations from climate breakdown聽and accelerate the transition to net zero under our Plan for Change.聽聽聽

From conception to construction, the satellite 鈥� called Biomass 鈥� has been built in the UK, capitalising on our industrial and academic expertise in space technology while opening up new opportunities to attract future backing from global investors watching its landmark launch on 29 April.聽聽

Throughout construction, it has supported approximately 250 highly skilled jobs at Airbus UK, in Stevenage, where it was manufactured, supporting the local economy and bolstering the UK鈥檚 52,000 strong space workforce.聽聽

The Biomass satellite will launch from Europe鈥檚 spaceport in Kourou, French Guiana.聽Since 2016, the UK has won almost 91 million Euros in contracts for Biomass through its membership of the European Space Agency (ESA).聽

Conceived by University of Sheffield academic Professor Shaun Quegan, it is a hallmark of British innovation, facilitating jobs in everything from design and development to assembly integration and test.聽The satellite will create a 3D map of tropical forests after 17 months, then new (non-3D) maps every 9 months for the rest of the 5-year mission, 聽providing insights normally hidden from human sight because of the difficulty in accessing these environments.聽聽聽

Its revolutionary technology will help scientists capture vital data on the changes to carbon in forests as ecosystems are increasingly impacted by deforestation.聽 聽聽

Minister for Space Sir Chris Bryant said:

The Biomass mission showcases British ingenuity at its very best, from conception in Sheffield to construction in Stevenage.聽聽聽聽聽聽

Britain is not only stepping to the forefront of the space industry, but of global climate action too.聽聽聽聽聽

Contributing to such great extent to a European mission set to deliver vital global results is testament to the UK鈥檚 industrial and academic expertise in space technology and will attract global investment into our vibrant space ecosystem, helping us boost growth and deliver our Plan for Change.聽

Both deforestation, which releases carbon dioxide, and forest growth, which soaks up CO2 from the atmosphere, are crucial parts of climate change.聽聽聽

Data on the biomass of tropical forests is very limited because they are difficult to access.聽聽聽聽聽聽

The Biomass satellite will be able to penetrate cloud cover and measure forest biomass more accurately than any current technology, which only see the top of the canopy. By providing better data it will help create a more accurate global carbon budget and better understanding of carbon sinks and sources which will help in developing and implementing effective strategies to achieve net-zero goals.聽聽聽

Observations will also lead to better insight into the rates of habitat loss and, as a result, the effect this may have on biodiversity in the forest environment.聽聽聽聽

Shaun Quegan, University of Sheffield鈥檚 Professor and lead proposer of the mission concept to the European Space Agency, said:

It鈥檚 been a privilege to have led the team in the development of a pioneering mission that will revolutionise our understanding of the volume of carbon held in the most impenetrable tropical rainforests on the planet and, crucially, how this is changing over time. Our research has solved critical operational scientific problems in constructing the Biomass satellite. 聽聽聽

Conceived and built in the UK, Biomass is a brilliant example of what we can achieve in collaboration with our partners in industry and academia. The mission is the culmination of decades of highly innovative work in partnership with some of the best scientists in Europe and the US.

Dr Paul Bate, CEO of the UK Space Agency said:

The Biomass satellite represents a major leap forward in our ability to understand Earth鈥檚 carbon cycle. By mapping the world鈥檚 forests from space in unprecedented detail, it will provide critical insights into how our planet is responding to climate change 鈥� helping scientists, policymakers, and conservationists take informed action. We鈥檙e proud of the leading role the UK has played in this important mission.聽聽

Kata Escott, Managing Director of Airbus Defence and Space in the UK, said:

Biomass is a groundbreaking mission that will advance our understanding of how carbon is stored in the world鈥檚 forests 鈥� delivering crucial data in the fight against climate change. With more than 50 companies involved across 20 nations, the team in Stevenage has shown exceptional leadership in delivering this flagship ESA mission.聽聽聽聽

Climate Minister, Kerry McCarthy, said:

The UK is back in the business of climate leadership and protecting the world鈥檚 forests through emerging and cutting-edge technologies is crucial to tackling the climate crisis.聽

This innovative tool shows how climate action attract investment in the UK, driving growth as part of our Plan for Change.
