Flatness map of floor

Flatness map in millimetres of the flattest floor by far in ESA’s ESTEC technical centre in the Netherlands – a 4.8 x 9 m epoxy floor smoothed to within 0.8 mm. The centrepiece of ESA’s new Orbital Robotics and Guidance Navigation and Control Laboratory, the floor is used for 2D simulations of contact dynamics in weightless conditions.
