NASA’s Pegasus barge has been modified to transport the massive core stage of NASA’s new rocket, the Space Launch System. The core stage, towering more than 200 feet, will store cryogenic liquid hydrogen and liquid oxygen to fuel the vehicle’s RS-25 engines. A 115-foot section of the barge was removed and replaced with a 165-foot section specially designed to increase the cargo weight Pegasus can accommodate and lengthening it from 260 feet to 310 feet - longer than a football field. Ken Hocke has more on Pegasus.
