SLS Rolls Out to Launch Complex 39B

Last night SLS left the Vertical Assembly Building (VAB) for the first time and made the slow 11 hour crawl to historic Launch Complex 39B. Over the course of two days SLS will be filled with more than 700,000 gallons of fuel and teams will rehearse launch operations all the way up to 10 seconds before launch including a 10 minute recycle. After the wet dress rehearsal SLS will return to the VAB while teams review data to make sure everything went according to plan. At this time the final launch window will be announced when SLS will take to the skies!
