View Full Version : First Polish (cube)sat in orbit

2012-Feb-13, 03:09 PM

The European Space Agency (ESA) has launched Poland's first ever satellite, the PW-Sat, from its Space Centre in Guiana, Monday.

The satellite was launched around 10.50 CET and has been built by students from the Warsaw University of Technology and scientists from the Space Research Centre at the Polish Academy of Sciences.

Primary mission objective is to use a deployable "tail" to deorbit the satellite via atmospheric drag:

"The system consists of a special tail ]deployable drag augmentation device] which will allow faster entry into the Earth's atmosphere,” says Maciej Urbanowicz at the Warsaw University of Technology.

The main objective of this experiment is to test the concept of using atmospheric drag to deorbit the satellite, says the ESA web site.

The "tail" is made of flexible solar cells. Testing the behavior of these is a secondary objective. CGI rendering of the bird in flight: http://www.youtube.com/watch?v=C3yBQSiLPFo

The bird also functions as an amateur radio satellite. Downlink has been received: http://www.uk.amsat.org/4657
