But the question hovering beneath the surface is whether America would ever be prepared to give Iraq a clean bill of weapons health so long as Mr Hussein, unrepentant, unregenerate and savage, remains in control.
The lander – named after a Chinese goddess of the moon – carried a six-wheeled moon-rover called Yutu, or Jade Rabbit, to its landing spot on a flat plain known as the Sinus Iridum, or Bay of Rainbows, after hovering over the surface for several minutes before selecting the best available landing spot.
Suppose a "point charge," such as a single electron, is hovering above a surface of a conductor.
So, just as it is natural to say that we perceive spatial distances and other relations between objects (I see the dragonfly as hovering above the surface of the water), it seems natural to talk of perceiving one event following another (the thunderclap as following the flash of lightning), though even here there is a difficulty.
The biggest drawback to the Hendo is that, in its current form, it can only hover over surfaces that also happen to be non-ferromagnetic conductors, e.g. copper plating.
When Apollo 11 reached the point of hovering over the lunar surface Neil Armstrong had 20 seconds to decide whether to continue or abort.
Until Saturday, these were all mock landings, in which the stage was brought to a hovering position at the surface of the ocean, where, without a solid platform to set down, every booster was then subsequently lost into the water.
The mean pressure distributions, when expressed in reduced coordinates, are self-similar and may be approximated by the pressure variation induced by an inviscid rotational vortex hovering above a flat surface in uniform smooth flow.
So far, there have only been mock landings, in which the stage is brought to a hovering position at the surface of the ocean, where, without a solid platform to set down, every booster has subsequently been lost in the water.
Earlier this year, a variety of circumstances compelled me to confront one of my core beliefs that had been hovering just beneath the surface: Life is hard.
