The orbit is not perfectly circular around the planet. It follows and eliptical orbit. Thats why the altitude will go up and down as it circles the planet. Most planets and satellites do not follow a circular orbit, but more or less of an elliptical one. |

Quoting: Goofy for God Nobody knows where or when the fragments will hit, but the European Space Agency has said the parts are likely to fall into the ocean or unpopulated areas. Potential spots will be narrowed down closer to re-entry, ESA said on its website. [link to www.cnn.com] One good thing is that humans on Earth needn't worry about is remnants of a nuclear powered or similarly fueled object. While that's the case for some other satellites, GOCE had been powered by solar panels and not-your-average lithium-ion battery. [link to www.cnn.com] ok did not know this [link to www.foxnews.com] Out of fuel GOCE satellite to crash-land on Earth Sunday afternoon Out of fuel GOCE satellite to crash-land on Earth Sunday afternoon ??? GUYS '' OUT OF FUEL '' '' FUELED BY SOLAR PANELS '' ?? WTF, SOME1 TURN THA SUN OUT ??? CUZ TODAY IVE SEEN IT... another lie ... its so simple & flat. .... its not even funny.... x_x THANK YOU!! One of the points I was making in my previous post!!! This does NOT add up!!!!! It hasn't run out of fuel, it has run out of propellant. You are right that it is "fuelled" from its solar panels with a backup battery. GOCE orbits at a low altitude for a satellite. The extremely thin atmosphere there creates a tiny amount of drag on the satellite so it needs to be aerodynamic and have a small engine to provide a little push to keep it in orbit. GOCE has an ion engine [link to en.wikipedia.org] The solar panels generate electricity that is used to accelerate xeon gas out of the engine at incredibly high speeds, providing the forwards thrust. It is the xeon gas propellant that it has now run out of. K |

One of the points I was making in my previous post!!! This does NOT add up!!!!! Of course it does add up IF you know what you are talking about. Solar power is used for the satellite's electronics. The satellite still needs small jet noozles for attitude correction and orbit decay prevention. Once it rans out of fuel for those small jets, it starts falling without control. Some other satellites use a small radoactive thermal source to generate electric power for the electronics. |

It says "with a very high probability, a re-entry over Europe can be excluded." Spokeswoman Jocelyne Landeau said the satellite, GOCE, will mostly disintegrate as it comes down and "we will have only a few pieces which could be 90 kilograms at the most."
