YES-2/Fotino space tether for re-entry experiment. The YES-2 tether was deployed from the Nauka module at the front end of Foton at 04:47 on 25 September, and releaed at 07:20 after reaching only 8.5 km of the planned 30 km tether length. The 5 kg Fotino reentry capsule separated from the MASS data support system at the end of the tether at around 07:30. The idea was to toss the Fotino against the direction of orbital motion to push it into a lower orbit and re-entry without the need for a retrorocket. Unfortunately the final outcome of the experiment remained unknown.
