Space beer, anyone? Hops flying on SpaceX's private astronaut mission Inspiration4 will be auctioned for charity

Billionaire Jared Isaacman is looking for a brewery to make beer with space-flown hops — for a good cause. 

The tech entrepreneur and experienced pilot has chartered a SpaceX flight to send himself and three other passengers, all private citizens, into orbit for a three-day mission in a Crew Dragon spacecraft. Called Inspiration4, the mission is scheduled to lift off Sept. 15 from NASA's Kennedy Space Center in Florida, riding to orbit on a SpaceX Falcon 9 rocket. 

Hitching a ride to space with the Inspiration4 crew will be 70 pounds (32 kilograms) of hops, an ingredient that adds bitterness and aroma to beer. And when that hops returns to Earth, Isaacman plans to auction it off to a brewery and donate the funds to St. Jude Children's Research Hospital, he announced on Twitter Aug. 12, adding that interested breweries should "inquire on"

Isaacman has also donated two of the four seats on the Inspiration4 mission to St. Jude, which is located in Memphis, Tennessee. One went to Hayley Arceneaux, a physician assistant at the hospital and childhood survivor of bone cancer. 

The second seat was given to Christopher Sembroski after he won the ticket to space in a fundraising raffle. That sweepstake brought in more than 72,000 donations totaling $13 million, in addition to the $100 million Isaacman pledged to donate. The fourth passenger will be Sian Proctor, the winner of an entrepreneur contest run by Isaacman's Shift4Shop e-commerce platform.

Isaacman's Inspiration4 mission won't be the first to launch beer-making supplies into orbit. NASA has flown hops to the International Space Station to brew beer in space for a student experiment, and Budweiser recently launched barley seeds to the orbiting laboratory to study the barley malting process in microgravity. Space-flown yeast has also been used to successfully brew "space beer" on Earth.

"Still shocked we don't have a brewery that is interested in making [beer] w/ hops flown on orbit higher than the Hubble telescope ... and to raise funds for @StJude along the way," Isaacman tweeted Thursday (Aug. 19), one week after he announced the auction. "C'mon breweries make history and get in contact with us."

The Inspiration4 mission team has not yet announced any details about the auction, like when or where it will take place, and the Inspiration4 team did not respond to's request for comment. But breweries interested in throwing their hats in the ring can formally do so at
