The competition heats up: Sierra Nevada has unveiled a revised cargo version of Dream Chaser, competing for NASA next round of freighter contracts to ISS.
They have made a number of changes, but the most significant is the new folding wings, allowing the spacecraft to fit inside the fairings of most rocket systems. This also eliminates one of the concerns I have read about the previous design on whether its wings could have withstood exposure to the maximum atmospheric stresses experienced during launch.
