YES2 has three components:
• Fotino: a small 6 kg capsule which will return to Earth.
• Mechanical data Acquisition Support System (MASS): an 8 kg carrier which holds Fotino in place with four straps. MASS will burn up in the atmosphere on re-entry.
• Foton LOcated YES2 Deployer (FLOYD): a 22 kg carrier bolted onto Foton-M3, which will eject MASS and Fotino towards Earth. Inside FLOYD is a spool with 30 km of 0.5 mm thick Dyneema® tether which is connected to MASS.
