On October 28, 2014, an Antares-130 rocket, from the French company ATK Orbital Science Corporation, exploded only 15 seconds after taking off. A failure caused it to fall on ramp 0A of the MARS launch center, in the state of Virginia, United States. Before it hit the ground, the destruction system was activated from the ground, preventing the facilities from being damaged.

The Antares-130 was an unmanned rocket destined to carry more than two tons of supplies for the International Space Station. From the first moment it was suspected that the fault of the fault had been due to two Soviet-manufactured NK-33 engines. Both engines had been manufactured in the 70s of the last century.

The accident report confirmed the suspicions. An explosion in one of the liquid oxygen turbo pumps caused the engine to lack thrust, and the subsequent crash of the Antares-130 rocket.

This fateful experience has led the company ATK Orbital to continue with its Antares rocket program, but without the NK-33 engines. They have been replaced by a new Russian engine, the RD-181 of NPO Energomash. The new version of the rocket will be called Antares-200, and will continue to provide, more safely, supplies to the International Space Station.
