We got our last look at Sentinel-5P yesterday. Following electrical checks, the covers protecting the Tropomi instrument were removed and the two fairing halves were installed, sealing the satellite from view. It was an emotional moment for us.
The fairing protects satellites from the thermal, acoustic and aerodynamic stresses on the ascent to space.
Yesterday was also the birthday of Bill Simpson, the launch campaign manager. What a birthday gift – encapsulating a satellite!
In a few days’ time the Ascent Unit will be transferred to the launcher on the launch pad.
