yup they could take any sat that's expired and ready to deorbit and just reuse it for destruction

> a series of manoeuvers by Kosmos2612 starting on Sept 30 were clearly designed to bring the two objects very close and synchronise their orbital periods, orbital altitude and eccentricity

so it's been in planning for a few weeks now

considering the SAR is US owned, that's going to be interesting politically if it suddenly stops responding

ISS has to move out of the way of debris a few times a year now, imagine what that's going to be like next decade
