The European Space Expo has officially opened in Dublin, with the travelling exhibition designed to demonstrate how space activities and applications can have a direct impact on our lives.

The expo has already visited over 12 European cities and is now set up in Front Square in Trinity College.

The European Commission and the European Space Agency organised the exhibition, which features a range of interactive and educational displays.

It also showcases the wide range of opportunities that developing applications for space can generate.

The European space manufacturing industry is currently worth €5.4bn a year and employs more than 31,000 people.

It is estimated that the market for global satellite navigation applications will reach €240bn by the end of the decade, with about 7% of European GDP, or €800bn, reliant on satellite navigation services.

The EU is currently funding a new smart satellite navigation system, Galileo, which will go live in 2014.

Another EU-funded programme, Copernicus, uses data collected by satellites to help us understand climate change and environmental issues.

The expo is open from 10am-6pm each day until Sunday and is free to the public.
