Excellent article; I've seen presentations on how we have to also do this for the Moon / A new atomic clock in space could help us measure elevations on Earth
A new atomic clock in space could help us measure elevations on Earth
The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

EU Commissioner for space and defence talking EU priorities for space: "All these new ventures are building blocks towards a European Space Shield to unite our defence efforts in space." I don't think he meant it in a Star Wars/SDI sense...probably

Commissioner Kubilius's speech at the European Space Conference
We, Europeans, can be proud of our achievements in space. Together we're worth a quarter of the global space economy. If we want to maintain our lead in space, we need to take bold and decisive steps.
