CAPE CANAVERAL, Fla. – Mark Geyer, NASA Orion Program manager, along with NASA Administrator Charlie Bolden, to his right, and Kennedy Space Center Director Bob Cabana help mark the T-6 months and counting to the launch of Orion on Exploration Flight Test-1, or EFT-1, inside the Operations and Checkout Building high bay at NASA's Kennedy Space Center in Florida. At left is Rachel Kraft, NASA Public Affairs Officer. The crew module has been stacked on the service module in the Final Assembly and System Testing cell. EFT-1 will provide engineers with data about the heat shield's ability to protect Orion and its future crews from the 4,000-degree heat of reentry and an ocean splashdown following the spacecraft’s 20,000-mph reentry from space. Data gathered during the flight will inform decisions about design improvements on the heat shield and other Orion systems, and authenticate existing computer models and new approaches to space systems design and development. This process is critical to reducing overall risks and costs of future Orion missions. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch later this year atop a Delta IV rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

The Exploration Flight Test-1 (EFT-1) Crew Module undergoes preparations to move from the Operations and Checkout Building at Kennedy Space Center to the KSC Visitor Complex on April 6, 2017.

Inside the Neil Armstrong Operations and Checkout Building high bay at NASA's Kennedy Space Center in Florida, the American flag is in view on the Orion crew module from Exploration Flight Test 1. Lockheed Martin and ASRC workers are preparing the crew module for its move to the nearby Kennedy Space Center Visitor Complex. The crew module will be delivered to the IMAX Theater where it will be on display in the NASA Now exhibit. The Orion spacecraft launched atop a United Launch Alliance Delta IV rocket Dec. 5, 2014, from Space Launch Complex 37 at Cape Canaveral Air Force Station. The spacecraft built for humans traveled 3,604 miles above Earth and splashed down about 4.5 hours later in the Pacific Ocean.

CAPE CANAVERAL, Fla. – Inside the Operations and Checkout Building high bay at NASA's Kennedy Space Center in Florida, Lockheed Martin technicians monitor the progress as a crane lowers the Orion crew module for stacking on the service module. The modules will be mated and then put through their final system tests before they are transported to the Payload Hazardous Servicing Facility for fueling. In the foreground, observing the processing, is NASA astronaut Anna Fisher. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. Orion's first flight test is scheduled to launch in December atop a Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.
