About this launch
XTAR-EUR is a communication satellite operating at 29 degrees East. Serving the needs of US, Spanish and allied governments. Maqsat B2 was designed to represent a commercial passenger for vehicle evaluation but was used as a technology platform for several European experiments, including Sloshsat in this case. Sloshsat is a satellite to investigate the behavior of liquids in weightlessness.
