From French Guiana to the stars: Ariane 5’s 25-year journey


For a quarter century, Ariane 5 has been Europe’s heavy-lift workhorse. Flying from Europe’s Spaceport in French Guiana, Ariane 5 has carried to space a long series of commercial and scientific missions. Notable payloads include ESA’s comet-chasing Rosetta, a dozen of Europe’s Galileo navigation satellites – orbited with just three launches – the NASA/ESA/CSA James Webb Space Telescope and, in April 2023, ESA’s Juice mission to Jupiter.

Ariane 5 more than doubled the mass-to-orbit capacity of its predecessor, Ariane 4, which flew from 1988 until 2003 as a favourite of the telecommunications industry with its need to put large payloads into very high geosynchronous orbits. Ariane 5’s capacity enabled it to orbit two large telecommunications satellites on a single launch, or to push very large payloads into deep space.

After 117 flights, Ariane 5 is being replaced by an all-new launch vehicle, Ariane 6.

  1. Europe's Spaceport … Isn't French Guiana located on South America?😁Beside that consideration, wonder why Senegal hasn't situated a Spaceport but mebbe some ESA involvement already but unaware? Something proposed on the East coast though, a project in Djibouti?


    Inside a singularity there is no such a dimension as length or height. Thus after the universe cedes to exist, it does become a singularity, but it will not contract. Inside a black hole infinitely big and infinitely small is the same, there is no difference.

    What I predict, is that the black hole, once it consumed all matter and dark energy, will turn into (what might seem for an observer outside of the universe) a White hole. A Big Bang, where dimensions of space once again become relevant. Light will never enter a White hole, that’s why it will be impossible to see beyond the borders of the Universe.

    We live inside a white/black hole!!!
