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.
