Ariane 6 is Europe's future rocket. It is the successor to Ariane 5. The Ariane 6 will come in two models, Ariane 62 and the heavier Ariane 64, that are basically the same rocket but with added solid-rocket boosters.Each Ariane 64 will be priced, for government missions, at 115 million euros when measured in 2014 economic conditions, compared with today’s Ariane 5, priced at 165 million euros. That means a 50-million-euro savings for each Ariane 64 launch for European government customers, or 25 million euros per satellite given that Ariane 64 business model, like that of the current Ariane 5, rests on launching two customer satellites at a time. ESA(European Space Agency) has identified seven Ariane 64 government missions — including two, the launch of the Juice mission to Jupiter and the Inspire science mission, which use the entire launcher — between 2021 and 2024. Flying these missions on Ariane 64 instead of Ariane 5 would result in savings to ESA governments of 225 million euros. In addition, the agency has identified 12 government missions that would fly on the less-powerful Ariane 62 rocket, to replace the current use of the Europeanized Soyuz vehicle starting in 2020 or 2021. Each Ariane 62 would be priced at 70 million euros for governments, or at least 10 million euros less than today’s Europeanized Soyuz, for a savings of 120 million euros.
