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.

A Russian Soyuz rocket lifted off from the Baikonur Cosmodrome at 2:07 a.m. EDT (0607 GMT) Monday with 38 small and medium-size satellites for customers in 18 countries.
