British built laser spacecraft due to be launched into orbit

A British-built satellite equipped with a 3.4-Kilowatt laser, as powerful as 840 light bulbs, will be launched into space this evening.

Flying at 200 miles above the surface of the Earth, the powerful laser on the European Space Agency’s (ESA) Aeolus spacecraft will beam down into the atmosphere and measure wind speeds – a completely new approach that could revolutionise the accuracy of weather forecasting, helping to protect people from disasters like floods and hurricanes across the world.

The spacecraft was built by Airbus Defence and Space in Stevenage. Other British businesses provided critical elements to the mission, including a camera, software and propulsion systems.

The substantial extent of UK participation was achieved through the UK Space Agency’s strong, ongoing support of ESA’s Earth Observation Envelope Programme, which benefits industry and science.

Science Minister Sam Gyimah said: “The Aeolus mission is a great example of the potential real-world impacts that space can have on Earth. Its data will lead to more reliable weather forecasts that can be used by farmers, seafarers, construction workers and others to improve productivity and safety.

“Space is a key part of our modern Industrial Strategy and it is work like this that shows how vital our role in the European Space Agency is in bringing real benefits to UK companies.”

Aeolus is the fifth of ESA’s Earth Explorer missions, which address critical Earth science issues, focusing on innovative missions and leading-edge technologies that deliver scientific excellence.

James Cotton, Satellite Winds Scientist, at the Met Office, said: “The Aeolus mission aims to improve the global coverage of wind profile observations, including areas where in situ wind measurements are currently lacking, such as over the oceans, in the tropics and the Southern Hemisphere.

“Within numerical weather prediction, we expect the Aeolus winds to be particularly useful for improving our analysis of the atmospheric state in the tropics, a region where we know the model wind errors are large.”
