For many years String theory has been a viable adjustment to the Standard Model of particle physics—a quantum field theory that cosmologists hope will unite all the fundamental forces of nature (weak, strong, electromagnetic, and gravitational). In other words, explain how the universe works. The problem so far has been that the Standard Model does not explain the gravitational force. And recently, String theory, without any experimental conclusions to back it up, has being challenged by other theories such as Loop Quantum Gravity.

Two years ago, a small spacecraft fell through a turbulent atmosphere to land on the surface of an alien world a billion or so kilometres from Earth. Since then, the data collected during its relatively short descent has continued to delight and amaze space scientists, amateur astronomers, and anyone with a passing interest in alien worlds, so it seems churlish to let the anniversary pass unnoticed.

On January 19, 2006, the NASA New Frontiers space mission called New Horizons was launched from Cape Canaveral, Florida, for its mission to the planet Pluto and its moon Charon. Now about one year later, astronomers are preparing for its flyby of the planet Jupiter before it reaches dwarf planets Pluto and Charon. Scientists estimate that its closest approach to Jupiter will be at approximately 06:00 UTC (coordinated universal time) on February 28, 2007, which is 1:00 a.m. eastern standard time.
