The Foton LOcated YES2 Deployer (FLOYD) element of the YES2 satellite with the 30km tether stowed inside. The tether – or “Florian” as it known to the team - for the mission is made a special material called Dyneema, which is a type of polyethylene. The exceptionally strong material is only 0.5mm thick. Although 30km of the tether will be deployed during the mission, Florian is actually 32km long. This extra takes into account the possible effects of particular forces on the tether in orbit.
