PW-Sat will go into orbit along with several other CubeSats early 2012, on board the new European Vega rocket. Launch will take place from the ESA space center near the town of Kourou in French Guiana (South America). This will be the maiden flight of the rocket. The CubeSat will be part of the main payload mission of the Italian satellite LARES (Laser Relativity Satellite).
It is a project of a picosatellite construction on the Basis of the Cubesat standard. It will be the first Polish satellite Entirely. It is of the big Rubik cube dimensions (10x10x10 cm) and Weighs 1 kg. Its assignment will be to Examine the possibilities of making use of the solar wind pressure and the background atmosphere in the circumterrestrial space to bring the old, used satellites back from the orbits. To this end, the PW-SAT will make use of a Specially designed sail, Which Will Increase significantly its aerodynamic drag and the surface Reflecting Light. The Obtained forces of resistance will allow, According to the constructors intention, then deorbit the satellite and cause its entrance to the atmosphere.
