Collated from a collection of announcements and websites. I hope  this
isn't considered off-topic.

An unmanned Foton-M  spacecraft carrying a mainly European payload was
put into orbit by a Russian  Soyuz-U launcher today at 14:00 Central
European Time (18:00 local time) from  the Baikonur Cosmodrome in
Kazakhstan. Following the launch and nine minutes  of propelled flight,
the Foton-M2 spacecraft is now in low-earth orbit where  it will remain
for 16 days before its re-entry module lands close to the  Russian/Kazakh
border.

The European payload carried by Foton-M2 covers  a scientific programme
consisting of 39 experiments in fluid physics,  biology, material
science, meteoritics, radiation dosimetry and  exobiology.

Of particular interest, the STONE-5 experiment considers  artificial
meteorites of sedimentary origin and aims to study the  physical,
chemical and biological modifications caused by atmospheric  entry.

Three different types of rock, loaded with micro-organisms, are  mounted
at the stagnation point in the heat shield (the hottest region  during
re-entry) of the Foton-M2 re-entry capsule. During re-entry into  the
atmosphere at the end of the two-week flight the three rocks will  be
subjected to temperature and pressure loads comparable to  those
experienced by meteorites.
