NASA has just announced they want to send manned flights to the Moon within 5 years. The plan has been to use the SLS for such flights as a launcher comparable in payload to the Saturn V, ca. 130 tons to LEO. The problem is this would require the Exploration Upper Stage(EUS) for the SLS, a large and expensive stage whose funding is still in doubt:

Instead of that I suggested use of the Ariane 5 core as the upper stage for the SLS here:

However, the Ariane 5 would be beyond the size and weight limits NASA wanted for the upper stage. But the Ariane 6 core will be a shortened version of the Ariane 5 core so may be within the size limits required by NASA. The Ariane 6 is expected to make its first flight in 2020 so NASA may have the needed Moon launcher by that time frame.
