Le satellite Terra de la NASA a effectué une manoeuvre d'évitement d'un des débris généré par le test antisatellite chinois du début d'année.
Le risque était faible mais non nul (6,7%), et a été ramené à zéro par la manoeuvre :

Terra successfully performed Risk Mitigation Maneuver on 6/22/07 with burn duration of 1.352 seconds. A week of tracking and analysis predicted a piece of Fengyun 1C debris with estimated probability of collision 7/100 (6.746e-2) prior to burn. Terra's thruster pulse 24 hours preceding the conjunction allowed 1.3 kilometers of separation to accumulate and reduce the risk to zero.
