Ariane 5


Last Updated . Click "Updates" above to see the latest.

Ariane 5 is a mid to heavy-lift orbital launch vehicle developed for the European Space Agency ESA.
Since the first launch in 1996 it performed 109 missions with only 5 failures. Two of these were total losses. The other 3 brought the satellites to a wrong orbit, so they had to expense some of their fuel to reach the assigned positions. Between 11th of December 2002 and 23rd of January 2018, 82 consecutive launches succeeded.
This makes Ariane 5 the most reliable start vehicles for orbital equipment and a huge success - like LEGO!

The technical data:
