Run Up To Launch

23:30 local time and we have just completed the pre-launch briefing being given by Thomas Ormston which covered the main aspects of tonight's activities. This included how the payload was prepped for launch, the fuel that the Sentinel uses and how the Vega rocket is actually mostly solid fuel.
There is a tradition here at ESOC that there is no cheering until the payload is successfully handed over to them from the launch team.
