World’s Largest Liquid Hydrogen Tank Nearing Completion

Construction of the world’s largest liquid hydrogen (LH2) storage tank is almost complete at launch pad 39B at NASA Kennedy Space Center (KSC) in Florida. With a usable capacity of 4732 m3 (1.25 Mgal), this new vessel is roughly 50% larger than its sister tank, which is located 170 m (550 ft) to the southeast. Once the new sphere is fully commissioned these two tanks will provide a combined LH2 storage capacity of 7950 m3 (2.1 Mgal) to fuel the new Space Launch System rocket in support of future Artemis exploration missions to the Moon and Mars.
