Future milestonesThe spacecraft is now fully configured for the execution of the first rendezvous manoeuvre that is planned for the next reporting period. Due to its magnitude, this manoeuvre has been split into five nominal burns plus an optional extra one in the event that a final correction is needed. The detailed plan for the burns is given in the table below.
