Cometary Fireworks Go Off Without Hitch

PingXao writes "The JPL Deep Impact mission has successfully slammed a sattelite into Tempel 1 at 23,000 mph. (37,000 kph). The autonomous navigation system was primed for up to 3 course corrections in the final 2 hours of flight but only had to execute two of them. The second was so small - expending less than a pound of propellant - that impact would have occurred without it. Initially thought to be shaped like a pickle, it came to resemble more of a banana shape as comet Tempel I drew closer. Impact was estimated to have released 19 Gigajoules of energy, or the equivalent of 4.5 tons of TNT."

    Fixed point in space?

    I think we have a potential solution to all those orbital corrections on the ISS. We simply need to find one of those "fixed points in space" and anchor the station to one, thus keeping it forever still. Additionally, we'll be able to figure out which way the earth/sun/galaxy/universe/etc is moving once and for all once we see which way the station flies off after being anchored...

    What's the name of that condition?
