Going to space is never routine, and Sentinel-2 mission controllers are leaving nothing to chance as they prepare for the critical days following next month’s liftoff.

As liftoff day draws closer, the Sentinel-2B ‘to do’ list is shrinking as tasks are ticked off, including the tricky process of fuelling the satellite. And, even despite having to do a few unexpected jobs, everything is on track for launch…
