Bigelow Aerospace's launch provider, Kosmotras is investigating a problem that they had with the SS-18 rockets used to launch the Genesis 2 inflatable space station. Kosmotras says that some of the Soviet rockets have a manufacturing defect that makes them blow up at bad times (at launch). While Kosmotras sorts this problem out, Bigelow has delayed the second test launch until April 1, 2007
