S&P's action leaves only three members of the eurozone with a top rating from all three agencies – Germany, Luxembourg and Finland. The Eurozone jobless data showed Spain's youth unemployment rate has now increased to 57.4%, only marginally below Greece's August high of 58% - which remains the highest rate of youth unemployment for any country in the eurozone's history. Italy's youth unemployment rate rose to 41.2%, from 40.5% the previous month. In Portugal, it rose to 36.5% from 36.2%.
The startling figures from southern Europe contrast with rates in the north where Germany has a 7.8% youth unemployment rate and the Netherlands an 11.6% rate. Italy's credit rating is perilously close to entering junk status and Rome is lobbying hard in Brussels for more time to cut the country's annual deficit. While the adult unemployment rate fell across the eurozone from 12.2 to 12.1%, 3.6m under-25s are now unemployed, an increase of 15,000 on the previous month.
He explained that there were three motivations behind the drive to investigate the Moon. "First, to develop our technology because lunar exploration requires many types of technology, including communications, computers, all kinds of IT skills and the use of different kinds of materials. Second, in terms of the science, besides Earth we also need to know our brothers and sisters like the Moon, its origin and evolution and then from that we can know about our Earth. And third, in terms of the talents, China needs its own intellectual team who can explore the whole lunar and solar system - that is also our main purpose."
The Moon is also "so rich" in helium-3, which is a possible fuel for nuclear fusion, that this could "solve human beings' energy demand for around 10,000 years at least. "The Moon is full of resources - mainly rare earth elements, titanium, and uranium, which the Earth is really short of, and these resources can be used without limitation. But it's unnecessary to get them now because it's very costly." Prof Ouyang summed up his vision for the goal of lunar exploration: "There are so many potential developments - it's beautiful - so we hope we can fully utilize the Moon to support sustainable development for humans and society."
