As I write, the GRAIL-A Spacecraft is less than 24 hours away from the moon. This is one of two spacecraft in NASA's latest GRAIL mission.

What is GRAIL? The GRAIL (Gravity Recovery And Interior Laboratory) is a new round of moon research using gravity measuring technology to determine and create gravity maps on the moon. This will allow scientists to have a look at the inside of the moon and spot structures hidden within the moon that cause gravity differentials. Measurements are preformed using very fine eletromagnetic based distance measurement techniques.

A similar project is taking place on earth now called GRACE, which was the first known usage of the technology and those interested will do well to refer to the links at the bottom of this article.

The GRAIL array will arrive in perfect time for new year:

GRAIL-A: Dec. 31, 2011

GRAIL-B: Jan. 1, 2012

This should shed some light on many of the moon theories -- if NASA releases the data anyhow and if both craft arrive on time.
