A new postal service... from space

In September 2007, the European Space Agency (ESA) will launch its Foton M3 mission from Baikonur. The spacecraft will carry the Young Engineers' Satellites (YES2) payload. The goal of this experiment is to send a 6-kilogram package from space to earth. This spherical parcel, named Fotino, will be attached at the end of a 32-kilometer-long tether. This tether, made of Dyneema, will have a thickness of only 0.4 millimeter. When it's completely deployed at an altitude of about 250 kilometers, it will be cut and Fotino will re-enter the atmosphere to land in Russia, inaugurating the first space postal service.
