Someone should run a live simulation of ROSAT's position from the NORAD data, but account for atmospheric effects between updates. Orbiter Spaceflight Simulator should give a reasonably good approximation of when re-entry occurs as long as its run in realtime and updated with the TLE sets as they're published. |

Quoting: Least Servant Everything we use has a service life and cycle. Typical industrial equipment lasts 20-30 years, average for a "durable good", so it's not surprising that we are going to start seeing this start to happen to some generations of space-born equipment in a group. This is roughly the same thing that is going on with our energy infrastructure, we saw so many oil pipelines go in the last two years, because a lot of the pipes were put in at the same time. Makes plenty of sense, but (and I hate to bring this up) don't forget Marshall Masters' idea that the more older of infrastructure (bridges,pipes) has been 'perturbed'. He has been terribly RIGHT about these "red dust storms." |

Not when it comes to satellites: From Wiki "End of life When satellites reach the end of their mission, satellite operators have the option of de-orbiting the satellite, leaving the satellite in its current orbit or moving the satellite to a graveyard orbit. Historically, due to budgetary constraints at the beginning of satellite missions, satellites were rarely designed to be de-orbited. One example of this practice is the satellite Vanguard 1. Launched in 1958, Vanguard 1, the 4th manmade satellite put in Geocentric orbit, was still in orbit as of August 2009.[17] Instead of being de-orbited, most satellites are either left in their current orbit or moved to a graveyard orbit.[18] As of 2002, the FCC now requires all geostationary satellites to commit to moving to a graveyard orbit at the end of their operational life prior to launch.[ |

Me thinks there are little spacemen playing a giant game of shoot 'em up or something. Actually, USA's first satellite, Explorer 1, re-entered the atmosphere some 41 years ago. You're probably thinking of Vanguard 1, which was not the first but is still the oldest satellite up there (not functional anymore of course). Its perigee was over 650 kms high, higher than ROSAT ever was, but it doesn't even spend that long at that altitude because its apogee was a whopping +3900 km high, which is why it has remained up there for so long. Not all orbits decay equally fast. Satellites with sufficiently high perigees and very high apogees like Vanguard can remain in orbit for hundreds of years. ROSAT, on the other hand, orbited at a lower altitude and had a circularized orbit. Last Edited by Astromut on 10/19/2011 04:15 PM |

Astromut Senior Forum Moderator User ID: 1322561 United States 10/19/2011 05:50 PM Report Abusive Post Report Copyright Violation | In 2000 we had a total of 54 satellites re-enter the atmosphere. That's an average of 4.5 per month. whats also wierd is that they cant predict the entry point correct, makes it look like they lost control and track of em saying oh it´s gonna be somewhere 53north 53south is like erm yes it can land everywhere. Quoting: ACThat's not unusual at all. It's not that they lost track of its current position, but its future altitude is dependent on the density profile of the earth's upper atmosphere which in turn varies with solar activity. If you recall, Skylab ended up re-entering much sooner than NASA originally predicted, which contributed to its loss; the original plan was to re-boost it with the space shuttle and continue using it. |
