==History==
The PW-Sat project was created in 2004 when group of students from Warsaw University of Technology decided to build satellite compatible with CubeSat 1U standard.〔http://www.spacedaily.com/reports/PW_Sat_Poland_first_satellite_launched_into_orbit_999.html〕 Initially planned for a 2007 launch, delays in the development of the Vega caused the mission to be postponed until 2012. The cost of the project is estimated to be 200,000 Polish zloty (63,205 USD), with funding coming from the university's budget, as well as from an agreement between Poland and the European Space Agency.
