NASA satellite reentry to exceed agency risk limits after late-stage design changes

Late-stage design changes to a NASA satellite increased the likelihood of an uncontrolled reentry and pushed the mission’s modeled ground-casualty risk above agency safety limits, agency documents say. The breach of NASA thresholds requires further assessment of reentry behavior and possible risk-reduction measures.
