The California-based international partnership Sea Launch Co. has launched a satellite for Intelsat customers from its land-launch operation in Kazakhstan.
The rocket lifted off Monday afternoon. Spokeswoman Paula Korn at the company's Long Beach headquarters said all was going well.
The launch was scheduled to take more than six hours, with three burns of the rocket's upper stage. It's the fourth land launch for Sea Launch, which is best known for launches from a floating platform on the equator.
The partnership of Boeing and companies in Russia, Ukraine and Norway has filed for bankruptcy reorganization, and Boeing may drop all or most of its ownership.
Korn said a hearing on new financing is due this week in bankruptcy court.
