With flat funding of about €500 million per year for 2013–17, the scientific programme takes a cut in real terms, although it is not yet clear which missions will be affected as a result.
But ministers did agree on a way forward for the Ariane program. Germany argued that ESA should continue to develop an upgraded version of the rocket known as Ariane 5 Midlife Evolution (5ME), which can carry payloads 20% heavier than its namesake and could put satellites in higher orbits. But France believed it was better to start building a new Ariane 6 rocket that would be cheaper to launch and therefore more competitive. In the end it was agreed that both projects should be developed over the next couple of years — with funding of about €600 million — and then both will be reviewed in 2014, with the goal that Ariane 5ME will launch in 2017 or 2018.
For robotic exploration, meanwhile, there is mixed news. On 19 November, ESA’s ruling council approved the involvement of Russia in the agency’s twin ExoMars missions to measure trace gases in Mars' atmosphere and search for signs of life on the planet's surface, scheduled for launch in 2016 and 2018. The Russian space agency Roscosmos will provide two Proton rockets for the lift-off and so plug some of the funding gap left when NASA pulled out of the mission last year. But just ahead of the Naples meeting, Germany announced that it would abandon plans for a lunar lander because it could not gather enough support from other member states to pay for the €500-million mission."
