With four days to liftoff, the next Sentinel satellite for Copernicus is now on the launch pad at the Plesetsk cosmodrome in northern Russia.
The rocket will be fuelled the day before the launch - set for 16 February at 17:57 GMT (18:57 CET).
The Sentinel-3A satellite has been at the cosmodrome since early December going through a series of tests and being readied for the big day. After being sealed from view in the rocket fairing earlier this week, it was rolled out to the pad today.
Bruno Berruti, ESA's Sentinel-3A project manager, said, "After years of hard work developing the mission, we all felt very emotional watching our satellite being encapsulated in the fairing knowing that that was the last time we'll see it."
