Airbus UK has been awarded nearly £95 million and Teledyne e2v £9 million, through the UK Space Agency’s membership of the European Space Agency (ESA), to deliver the next phase of the TRUTHS mission.
The funding to Airbus will go towards satellite design and development, while Teledyne e2v will work on a sensor, called the Hyperspectral Imaging Spectrometer Detection System, and associated electronics. This instrument will make measurements of ocean and land surfaces to support studies of Earth radiation budgets and improve observations that support the modelling of climate, land use change, the carbon cycle, agriculture and pollution.
TRUTHS, which stands for Traceable Radiometry Underpinning Terrestrial- and Helio- Studies, will collect the most accurate measurements of energy coming into the Earth from the Sun, and light reflected off Earth’s surface. This will significantly improve understanding of changes in the Earth’s climate and inform global action to mitigate them.
Science, Research and Innovation Minister, Andrew Griffith, said: “This UK-led mission will have a global impact, providing invaluable measurements to improve our understanding of our climate. Thanks to British skills and expertise, this work is generating growth and developing important industrial capabilities across our space sector, driving forward our ambitions to cement the UK’s place as a science and technology superpower.”
Due to launch in 2030, the ground-breaking mission will create a ‘climate and calibration observatory in space’ which will reduce uncertainty in Earth observation data and set a new benchmark to detect changes in Earth’s climate system. This will build confidence in climate action by linking observations from space unequivocally to international measurement standards.
Conceived by the UK’s National Physical Laboratory and initiated by the UK Space Agency, TRUTHS is being developed by ESA. The satellite will be built by the UK space industry, led by Airbus UK, along with partners across Europe, including Greece, Spain, Switzerland, Romania and Czech Republic, which have also provided funding for the mission.
Dr Paul Bate, chief executive of the UK Space Agency, who has been at COP28 this weekend, said: “This a major milestone for the TRUTHS mission and fantastic news for our world-leading Earth observation sector.
“The mission will play a vital role in improving how we monitor climate change using satellite data and supporting the decisive climate action which global nations are negotiating at COP28.
“But TRUTHS is more than something to monitor the planet, it is an exemplar of how the industry can incorporate sustainable space operations and reduce carbon impacts through the life cycle of the mission.”
