Move Over Heavy Metal, There’s A New Tank Coming To Town

For more than 50 years, metal tanks have carried fuel to launch rockets and propel them into space, but one of the largest composite tanks ever manufactured may change all that. This spring, that tank–known as the composite cryotank–is set to undergo a series of tests at extreme pressures and temperatures similar to those experienced during spaceflight.

“NASA focused on this technology because composite cryogenic tanks promise a 30 percent weight reduction and a 25 percent cost savings over the best metal tanks used today,” said Michael Gazarik, associate administrator for NASA’s Space Technology Mission Directorate. “It costs thousands of dollars to deliver a pound of cargo to space, so lighter tanks could be a game changer allowing rockets to carry more cargo, more affordably.”
