The CRS-1 mission involved the transport of materials to support investigations planned for the station’s Expedition 33 crew, as well as crew supplies and space station hardware.

   “The Dragon spacecraft is on its way to the International Space Station this morning and is performing nominally,” SpaceX said in a company statement. “Approximately one minute and 19 seconds into last night’s launch, the Falcon 9 rocket detected an anomaly on one first stage engine. Initial data suggests that one of the rocket’s nine Merlin engines, Engine 1, lost pressure suddenly and an engine shutdown command was issued immediately. We know the engine did not explode, because we continued to receive data from it. Our review indicates that the fairing that protects the engine from aerodynamic loads ruptured due to the engine pressure release, and that none of Falcon 9’s other eight engines were impacted by this event.”

   The SpaceX CRS-1 mission marks the first of at least 12 SpaceX missions to the space station under the company’s cargo resupply contract with NASA.
