The private company Space X will try once again to get a Falcon 1 rocket into orbit. This fourth launch attempt could be as early as September 28!
They just had a "static firing" a test of the engines with the rocket strapped down. Everything looked pretty good, but they detected a minor fault in the second stage liquid oxygen supply. They'll be replacing a component in that system just to be safe.
