Yesterday Juan and Natalie glued the second layer of the side scoop, liquid nitrogen filling of the cryostat started, and the mirrors were mounted. There was also the England vs. USA match in the World Cup, which distracted a large portion of the team. Especially when the English keeper let in a terrible goal.
In the early evening Tristan gave us a slow motion disco performance, for the sake of the day’s timelapse video.
