Sorry, couldn't find a previous thread on the subject of Arianespace launchers...
Arianespace has split its third order of Vega rockets from Italy’s Avio between old and new versions of the solid-fueled booster, as officials prepare to build a final batch of around 18 Ariane 5 rockets before switching to the next-generation Ariane 6 in the early 2020s.

Approval given for Ariane 6 the proceed - still no sign of anything innovative like reusability

I'm not a fan of sold rockets, but the trouble with liquid hydrogen as the main fuel is that it doesn't have a lot of "grunt" to get a heavy rocket off the pad.
And the structural mass of a large 1st stage needed due to the low density of LH2 also counts against it. Much more sensible to use a higher density fuel such as RP1 and keep the cryogenic fuel for the upper stagesEdited by Beati Dogu on Monday 9th July 21:49
The first qualification model of the P120C solid-fuel motor, configured for Vega-C, was static fired yesterday on the test stand at Europe’s Spaceport in French Guiana.

The upper stage of an Ariane 4 launched over 20 years ago has broken up in orbit

I wonder what could have caused it to go pop after so long - I'd assume anything holding pressure would have been vented long ago

Probably not, unless they used it for thrusters or engine starts. Third stages like his were powered by liquid hydrogen & oxygen.
It was attitude control thrusters I was thinking of rather than the main rocket motor. The Vega is a solid fueled rocket, isn't it.Report into the Vega VV15 launch failure concludes the probable cause was associated with failure of the forward dome of the 2nd stage motor
