Orbital has rescheduled the launch of its Antares rocket for the Orb-2 mission to a date of no earlier than (NET) June 17, 2014.
Orb-2 is the second of eight cargo resupply missions to the International Space Station under Orbital’s Commercial Resupply Services (CRS) contract with NASA. The new launch schedule has been established to allow the engineering teams from the main stage propulsion supplier Aerojet Rocketdyne and Orbital to investigate the causes of an AJ26 engine failure that occurred last week at NASA’s Stennis Space Center during customary acceptance testing.
That engine was designated for use in a mission slated for 2015 and was undergoing hot fire testing that all Antares AJ26 engines are subject to in order to ensure nominal performance and acceptance for use in Antares missions. The NET June 17 is a planning date. The determination of a new firm date will depend on progress of the investigation team, so please check back to this page for further updates.
