Welding steel plates at the webs of all structural beams provided the additional reinforcement. The new green roofing system and its nearly 70,000 plants help eliminate the heat-island effect, reduce storm water runoff and increase the building's energy efficiency.īecause the roof holds nearly 1.2 million lb of soil, it required additional structural support.

The roof rebuild is one of the most interesting features of the $16.5-million project. The project team completely dismantled Building 12 and stripped it down to its structural-steel frame. The data gathered during the flight will influence design decisions, authenticate existing computer models, and innovative new approaches to space systems development It also will reduce overall mission risks and costs for subsequent Orion missions to an asteroid and eventually Mars.The renovation involved all parts of the facility, including interior, exterior skin and roof. It will orbit Earth twice before re-entering the atmosphere as fast as 20,000 mph. During that flight, an uncrewed Orion will launch to an altitude of 3,600 miles, more than 15 times farther into space than the International Space Station. They used strip heaters to heat one of the fairings to 200 degrees Fahrenheit and simulate the temperatures the panels will experience.Įxploration Flight Test-1 is scheduled for September 2014. Because of the engineers’ confidence in successfully eliminating the interference, they maintained plans to increase this week’s test fidelity by emulating the thermal loads experienced by the fairings during ascent. Engineers determined the issue was caused when the top edge of the fairing came into contact with the adapter ring and kept it from rotating away and releasing from the spacecraft. The first occurred in June, when one of the three fairing panels did not completely detach. This test, conducted by Orion’s primary contractor, Lockheed Martin, at the company’s Sunnyvale, Calif., facility, was the second test of the fairing separation system. Once all of the pyrotechnics have detonated, six spring assemblies will push the three panels away, leaving the service and crew module exposed to space as they travel onward. In a carefully timed sequence, the joints are fired apart, followed shortly by the bolts. To make that possible, six breakable joints and six explosive separation bolts are used to connect the fairing panels to the rocket and each other. They must be jettisoned when Orion has reached an altitude of about 560,000 feet. The fairings’ work is done soon after launch. Each panel is 14 feet high and 13 feet wide. Unlike conventional rocket fairings, these panels are designed to support half of the weight of Orion’s crew module and launch abort system during launch and ascent, which improves performance, saves weight and maximizes the size and capability of the spacecraft. “We want to know we’ve got the design exactly right and that it can be counted on in space before we ever launch.” “Hardware separation events like this are absolutely critical to the mission and some of the more complicated things we do,” said Mark Geyer, Orion program manager at NASA’s Johnson Space Center in Houston. During Exploration Flight Test-1 (EFT-1), the spacecraft’s flight test next year, a test service module will be attached to the capsule. The service module will remain connected to the crew module until just before the capsule returns to Earth. It also will generate and store power and provide thermal control, water and air for the astronauts.

The service module, located directly below the crew capsule, will contain the in-space propulsion capability for orbital transfer, attitude control and high-altitude ascent aborts when Orion begins carrying humans in 2021. The panels, called fairings, encase Orion’s service module and shield it from the heat, wind and acoustics it will experience during the spacecraft’s climb into space. The three massive panels protecting a test version of NASA’s Orion multipurpose crew vehicle successfully fell away from the spacecraft Wednesday in a test of a system that will protect Orion during its first trip to space next year. 6, 2013 at Lockheed Martin’s facility in Sunnyvale, Calif. The three panel or fairings encapsulating a stand-in for Orion’s service module successfully detach during a test Nov.
