Designation 32058 / 07040A
Launch date 14 Sep 2007
Country of origin CIS
Mission Scientific: microgravity studies
Perigee/Apogee 258/280 km
Inclination 53°
Period 90 min
Launch vehicle Soyuz #878

The capsule carries a 400 kg European experiment payload with approx 40 experiments in a range of scientific disciplines - including fluid physics, biology, crystal growth, radiation exposure and exobiology.

There are also some NASA experiments on board experiments that are to increase fundamental knowledge of the effects of space on genetics, cell proliferation and tissue regeneration, as well as the physiological effects of microgravity.

In addition, the Young Engineers Experiment (YES2) is to be deployed from the Foton capsule. On 25 September, a small re-entry capsule was released from a tether measuring 31 km. The Fotino capsule was released. Yes2 was to demonstrate the possibility of returning small payloads to Earth at a fraction of the cost of current methods.
