HIT Research Center of Satellite Technology Harbin

Am 19.09.2015, 23:01:14 UTC startete eine CZ-6 Rakete (Langer Marsch 6) vom Taiyuan Satellite Launch Center in Shanxi (China) und brachte 20 Satelliten ins All. Mit dem Debüt einer neuen Familie von Trägerraketen begann China eine neue Ära in der Erforschung des Weltraums.Mit einer Länge von fast 30m und einer Gesamtmasse beim Start von 103.217kg ist die CZ-6 für den Start kleinerer Nutzlasten konzipiert. Neben sechs XW-2 (CAS-3A-F) Amateurfunksatelliten, befand sich LilacSat-2, der von Studenten des HIT Research Center of Satellite Technology Harbin entwickelt wurde.
