James Evans writes: "NASA has successfully launched GRACE (http://www.csr.utexas.edu/grace/). The Gravity Recovery and Climate Experiment uses 2 satellites, which communicate via a microwave ranging system, in an effort to map the Earth's gravity fields with amazing accuracy."

Finally, I will know!
Also, fun fact: Gravity is negative energy. The negative gravity energy of an object exactly balances out the positive mass. This way the total energy of the universe is 0. That means the big bang did not violate conservation of energy. It was just a vacuum fluctuation.
Since the total energy of the big bang vacuum flucuation was zero, it can last forever. This is in contrast to most microscopic vacuum fluctuations that only exist for short periods of time.
