An Ariane 5 rocket has been launched from French Guiana carrying two important satellites into space. It is the third Ariane launch this year.
Alphasat is the biggest telecommunications satellite ever built in Europe.
The result of a public-private partnership between the European Space Agency and Inmarsat, it will help the UK-based operator extend its global network across four continents.
The other satellite, Insat-3D, has been launched by India and is said to add a new dimension to weather monitoring. Part of its mission will be to help offset the impact of storms and natural disasters.
The satellite’s atmospheric sounding system will provide data about temperature, humidity and ozone levels.
It also has equipment designed to help with search and rescue operations.
