Just read at MSNBC that a large U.S. spy satellite will hit Earth by the end of February or early March.
Better keep our hard hats ready??? Here is the article: http://www.msnbc.msn.com/id/22857051/ |

If the intercept is successful in mitigating the hazard material problem, then it could be used for future similar cases without incurring development costs of an on-board hazard reduction mechanism and the associated mass penalty. The incremental cost of the intercept would be expended only if the contingency actually occurred rather than adding the cost to the spacecraft in anticipation of the contingency.
The intercept option would not work for hazard from a re-entry immediately following a late launch failure. Not too bad if the impact zone is over water, but very crappy if over land. |
