- Abstract
The second Young Engineers’ Satellite (YES2) is a mission to demonstrate the re-entry of a light weight capsule by the use of a Tether rather than a conventional retro rocket. The satellite is built by European Students in close cooperation with the ESA Education Department, through a contract with Delta-Utec SRC from the Netherlands. The hardware will be launched together with the ESA Foton-M3 mission, on a Soyuz launch vehicle carrying a Foton satellite where YES2 is attached, on September 14 2007 from Baikonur Kosmodrome.
The mission hardware consists of three main elements, FLOYD - the Foton Located YES2 Deployer, MASS - the Mechanical and data Acquisition Support System and Fotino – a re-entry capsule. The total hardware mass is 36 kg, of which 12 kg will be deployed on the end of a 5.5 kg, 30 km long, 0.5mm thick tether. Through momentum transfer utilising the gravity gradient and the Coriolis effect the 5.5kg Fotino together with MASS will be lowered into a orbit where its speed is so that when Fotino is released from MASS, it will not make another orbit, but hit the atmosphere and eventually re-enter and land 30 minutes later. MASS and Tether will be cut in the FLOYD end 10 seconds after the release of Fotino, causing also them to hit the atmosphere but burn completely. During the deployment the tether will be among the brightest object on the sky in areas close to twilight. When the tether is fully deployed it will be the longest man-made object in space ever. The Foton satellite will orbit the Earth in a near circular orbit at 280 km altitude. The Foton satellite will on the day after Fotino landing, re-enter its own Foton capsule carrying other experiments. FLOYD will remain attached to the more than 6500kg Foton during the whole mission. The YES2 mission is performed during day 11 of the Foton-M3 mission, with the expected landing zone in the area of Kazakhstan.
The MASS is equipped with a GPS/Glonass receiver, and instruments for attitude determination. There will be a telemetry link between FLOYD and MASS, which is relayed through the Foton satellite to ground. Fotino is equipped with its own telemetry system which will be activated during re-entry. Fotino will be transmitting on a frequency that can easily be picked up with radio amateur equipment. Fotino also carries a ARGOS beacon for determination of the landing point. Fotino will land in its own parachute reducing the impact speed to less than 10 m/s.
