'Rapid progress' on Ariane 6

Manufacturers say they are making rapid progress in the development of Europe's new rocket - the Ariane 6.

The vehicle is due to enter service in 2020, gradually replacing the existing workhorse, the Ariane 5.

The prime contractor is the recently rebranded ArianeGroup. Its CEO Alain Charmeau spoke with our science correspondent Jonathan Amos at the Paris Air Show.
