3.5 Ton Satellite to Crash Back to Earth

DeadBugs writes "CNN is reporting that the NASA Extreme Ultraviolet Explorer could crash back to earth in a matter of days. It's estimated that up to 9 large pieces (4-100 lbs.) of the Satellite could survive re-entry. Unlike the Compton Gamma Ray Observatory that was guided in, this Satellite will be uncontrolled. The EUVE has only been up there since 1992.... I wonder when this sort of thing will start to be a more common event."

      You're right about one thing, though. Neither you nor your friend is a physicist ;-)

      Objects in orbit around the Earth sometimes fall to earth, because they're in low enough orbits that atmospheric drag is a problem.

      Other objects in orbit around Earth (like the Moon) are far enough away that there is no atmospheric drag, and they remain in orbit indefinitely. (Ignoring tidal effects.)

      The Earth is most assuredly not spiralling closer to the sun. That would require that the Sun gain significant mass during its life, which Just Doesn't Happen. (Nor are we spiraling away from the Sun in any measurable fashion. Yes, the Sun loses 4000 tons of mass every second (by turning matter into energy), and that may sound like a lot of mass, but it's negligible in comparison to the total mass of the Sun.)

      And as for global warming, the "ozone hole" is about an increase in ultraviolet radiation hitting the Earth, potentially causing an increase in skin cancer rates, as well as destruction of habitats such as the top few centimeters of the oceans (read: "plankton, significan portion of the food chain"). The ozone layer has nothing to do with global warming.

      GEO is geosynchronous orbit; that is, an orbit that is synchronous with the Earth's rotation. A satellite in GEO will appear to remain fixed above a point on the equator, as it would by definition have an orbital period of one day. Obviously, the rotation of the Earth has an awfully lot to do with GEO, since it sets the period and therefore the orbital radius. (Relatively simple physics tells that, if the centripetal acceleration must be provided by the Earth's gravity only, then T^2 is proportional to r^3, and so there is exactly one radius that can yield a circular orbit of given period T).


      Minor disclaimer: I believe the definition of GEO also states that the satellite orbit in the equatorial plane of the Earth, so as to remain "fixed" in the sky. Other orbits with period 24 hours can be imagined, but the Earth would "rotate under" them in a complicated -- probably Lissajou -- figure.


      Here's the real rub: The actual radius that comes out is huge ... about 36,000 km, IIRC. That's a helluva lot farther than, say, the Shuttle orbits (around 300 km off the Earth, or 6700 km from the center). The atmosphere can be well-modeled as exponentially decaying in density. That means if air is rarefied at the Shuttle's orbit (and it is), it is more or less non-existent at GEO. Conclusion: atmospheric drag is negliglible. The time scale for a GEO satellite to decay is, I believe, millions of years. There is a slight issue with gravitational radiation but I'd bet real money that it is even more negligible.


      Finally, as an aside, the Moon is not spiralling into the Earth. In fact, quite the opposite is occuring: The Moon is receding, making up for the angular momentum lost in the Earth-Moon system due to the tidal slowing of the Earth.

    As you point out, it would have to pose no danger to other spacecraft. Well, the only practical way to do that is to ditch it in a controlled fashion. Any explosion involves a release of energy in pretty much all directions. Although some shaping of the charge can control the blast, you still blast some pieces in every direction. Each piece that does not hit the atmosphere enters its own orbit - risking collision with some other satellite.

    The proper solution, employed by almost all responsible satellite designers, is to allow enough extra fuel to deorbit the satellite. Of course, this depends on having CONTROL of the satellite. To guarantee this requires more redundancy - and more weight and fuel and complexity, etc. At the tens or hundreds of thousands of dollars a pound for launch costs, the designers usually opt for mission-suitable redundancy, and hope (and pray) that all the systems don't fail before they DO deorbit. And if they do start failing unusually fast, they'll deorbit early to avoid this kind of fiasco.

    The weather in low earth orbit is just as unpredictable as the weather at the ground, and just as variable. The density of the atmosphere around satellites (and thus the drag force on them) can vary by an order of magnitude. If the satellite loses orientation (which it is essentially certain to as drag forces overcome tidal or powered stabilization) then its coefficient of drag changes as well, and unpredictably when it rotates. It may not even have just drag acting on it; even in orbit an angled surface can produce just as much lift as drag, and when the satellite hits the atmosphere its shape could produce more lift than drag.

    And of course, for every second by which the atmosphere delays reentry, the satellite has moved 5 miles in its orbit. 5 mi/s * 3600 s/hr * 9 hr gives a nice 160,000 mile strip of possible landing sites, crossing around and around the whole globe.

  113. Why are they letting another satellite come down? by plik · · Score: 1

    I can't help but be confused. You repeatedly hear about the high cost of sending stuff into orbit. It seems to me that a little investment in creating some kind of space junkyard of sorts might pay off.

    The same thing goes with Mir. We hear about how the ISS is so far over budget, but how come we let Mir crash and burn rather then integrating it into the existing ISS plan? Even if we ripped out all of its guts and let the vacuum of space kill the fungus that was growing in it, thats still a whole hell of a lot of metal that could possibly be pressurized and turned into a living/labrotory space.

    But whatever.

  114. Good bye EUVE by FUSENerd · · Score: 1
    I used to work on EUVE as a planner, it'll be sad to see it go.

    Contrary to what a lot of people are guessing, EUVE had no onboard thrusters or fuel of any kind, so there is no way to control re-entry. The re-entry has nothing to do with the decomissioning, and everything to do with the fact that atmospheric drag is finally bringing it down. EUVE would have lasted longer in a higher orbit, but those are much more expensive, and it just wasn't practical. This is the case for the vast majority of low earth orbitting satellites (and especially inexpensive astronomy statellites that aren't out to make a profit).

    Satellites like EUVE can change their pointing by spinning reaction wheels -- that's how the telescope was pointed at different targets all over the sky -- but merely rotating the satellite around does nothing to affect when it's going to re-enter.

    The probability of the few EUVE surviving pieces falling into a populated area and hurting someone is very small

    This is the very type of remark that I hope does not lead to lessening of accountability in the future. The probability of actually needing to use your airplane seat as a floatation device is also extremely small, but they spend the extra money to provide it, just in case.
