Advanced details

Weighing 13.5 tons (13,500 kilograms), the Castor-Orbus had a lift-off thrust of approximately 430 kilonewtons (equivalent to around 96,660 lbf). The rocket had a core diameter measuring 1.02 metres (3.34 feet), with a total length of exactly 16 metres (52 ft). It had an apsis (apogee) of over 500 kilometres (310 mi). The family of the Castor-Orbus rocket was Castor 4, which was partially responsible for the Castor-Orbus naming.

Career

The Castor-Orbus rocket was launched three times over almost five years. After the launch of October 4, 1997, the Castor-Orbus was dropped from service.

  • The first launch of the Castor-Orbus took place on October 16, 1992 at around 6:30 am. The location of the launch was Wake Island, in the North Pacific Ocean. This launch proved to be a failure.
  • The second launch took place almost five years later, on February 10, 1997 at the Nevada Test Site, in Nevada, USA. This launch would prove to be the first and last successful launch of the Castor-Orbis.
  • The final launch of the Castor-Orbus was not successful. It took place on October 4, 1997, at the Nevada Test Site.
