Orion Status Update-April2012

Orion Status UpdateApril 2012Kennedy Space Center Orion Team Welcomes New ArrivalThe Orion Ground Test Vehicle arrived at NASA’s Kennedy Space Center Operations & Checkout (O&C) Facility on April 21. The vehicle traveled more than 1,800 miles from Lockheed Martin's Waterton Facility near Denver, Colo., where it successfully completed a series of rigorous acoustic, modal and vibration tests that simulated launch and spaceflight environments.The ground test vehicle will now be used for pathfinding operations at the O&C in preparation for the Orion spaceflight test vehicle's arrival this summer. The spaceflight vehicle is currently being fabricated atNASA’s Michoud Assembly Facility in New Orleans, La., and is slated for NASA’s Exploration Flight Test (EFT-1) in 2014.Orion -- the na tion’s first interplane tary spacecraft forhuman space exploration beyond low Earth orbit -- will be fully assembled and integrated on site at Kennedy Space Center , a new capability that provides significant time and cost savings. The O&C’s 90,000 square feet of air-bearing floor space and specially designed air-bearing pallets enable a small crew to effortlessly maneuver spacecraft across the factory floor.

The portableclean room enclosure components (pictured at left,behind the crew module) are placed throughout the O&C high bay to achieve cleanliness levels required to integrate all the elements of the Orion spacecraft. This modular system, coupled with modern energy efficient Heating, Ventilation & Air Conditioning (HVAC) and electrical systems, will further enhance cost savings for the life cycle of the facility. This system enables the 90,000-square-foot high bay to maintain the proper environments to meet the cleanliness levels required for spacecraft processing without taking on unnecessary costs associated with fixed clean room systems.There are currently about 300 employees with NASA, Lockheed Martin, USA, and Honeywell working on the Orion program at Kennedy Space Center. That number is expected to grow to 350-400 by the end of 2013 as the flight test date approaches.At Michoud Assembly Facility, the Orion team is nearingcompletion of welds on the Orion flight test vehicle using theinnovative self-reacting friction stir weld process createdcollaboratively by NASA and Lockheed Martin.Welding operations progressed on t he crew module structure(pictured at right) as the barrel-to-aft-bulkhead weld and the aftbulkhead cap weld were completed in March.The team also started the non-destructive evaluation (NDE)process and preliminary visual inspections. The remaining welds tocomplete the crew module structure include: the tunnel to forwardbulkhead weld, the forward bulkhead to cone weld, and the finalcloseout weld joining the cone section to the barrel.Fabrication of the composite service module panels also showedsignificant progress. The team completed work on the shear panels,inboard walls, and forward walls. In addition, several of the panelscompleted fiberplacement,non-destructive evaluation and trim testing. All the servicemodule panels are made of a mix of carbon and epoxylaminate and have a lightweight core, providing structuralstrength with minimal weight.The Orion crew module and service module structural elementswill be delivered to the O&C facility this summer for finalassembly and systems outfitting on the flight test vehicle.Pictured at left is fiber placement work in progress on one of theOrion service module shear panels.All photos courtesy of NASAFor more information:Linda SingletonLockheed Martin Orion Communications832-526-8089 linda.singleton@/orion or /orion。
