Blanket to shield SLS engines

The heat shield around the Space Launch System RS-25 engines will not be the same as the Space Shuttle Program. The decision was made to move to a lighter, more flexible blanket, similar to the ones used on other vehicles and on the aft skirt of the Solid Rocket Boosters. The new blanket design will save about 700 pounds and will be easier to produce, assemble and install. The design change will debut during the test firings at NASA’s Stennis Space Center in Mississippi. (Source: NASA Spaceflight, 09/03/12)
