If German Satellite Falls on Your House, Who Pays for Repairs?

The defunct 2.7-ton German ROSAT satellite is slated to make a fiery, uncontrolled re-entry to our atmosphere sometime Saturday or Sunday (Oct. 22 or 23). Experts say the broken-up bits of ROSAT have a roughly 1-in-2,000 chance of hitting someone somewhere on Earth, though they won't know where until a few hours before it enters the atmosphere.

Let us be clear: There's an extremely remote chance that ROSAT will fall on you . But, for good measure, if ROSAT, or some other spacecraft, did fall on your property , could you keep it? And, if the bus-size satellite flattened your house, who would be on the hook for the repair bill?

The good news is that if the satellite, or even just sizable chunks of it, did in fact slam into your house, you wouldn't need to sell your new space souvenir to pay for repairs. By international law, the three countries would have to foot the bill.

Liability for damage caused by objects falling from space is regulated by the 1972 Convention on International Liability for Damage Caused by Space Objects. All three countries involved with ROSAT have signed the pact, and in doing so agreed to be "absolutely liable to pay compensation for damage caused by its space object on the surface of the Earth or to aircraft in flight." That goes if ROSAT crashes down in Kansas, France or Zimbabwe.

The terms cover just about everything. In this case, "damage" is defined as loss of life, personal injury or other impairment of health; or loss of or damage to property of states or of persons, natural or juridical, or property of international intergovernmental organizations.

And the payout is fairly good. Again, quoting the treaty: "The compensation which the launching State shall be liable to pay for damage under this Convention shall be determined in accordance with international law and the principles of justice and equity, in order to provide such reparation in respect of the damage as will restore the person, natural or juridical, State or international organization on whose behalf the claim is presented to the condition which would have existed if the damage had not occurred."

One slight hitch in the treaty is that you have to present your claim no later than one year following the incident (or discovery of the damage). If you've got a truck-size satellite sitting in your living room, however, we suspect that satisfying this condition would not be an issue.
