text:  Ariane, I mean, yes, launchers are quite big, but like you said, it's a heavy lift launcher, which for us means getting something like 20 tonnes of payload into low Earth orbit. The predecessor, Ariane 5, was taking 20 tonnes of supplies to the International Space Station, for example. So the launcher itself is over 60 metres tall and it's about 900 tonnes at liftoff weight. So that's one and a half A380, Airbus A380s. Goodness me. And this is an expendable rocket or what, partially expendable, is that right?
