With NASA’s Perseverance Rover set to make its landing on Mars this Thursday, February 18, Krispy Kreme Doughnuts is giving fans a unique opportunity to celebrate with its limited-edition Mars Doughnut.

The Mars Doughnut is made to look like the red planet, featuring a Chocolate Kreme-filled doughnut dipped in caramel icing with a red planet swirl and sprinkled with chocolate cookie crumbs. For one day only on February 18, the doughnut chain will give each one free Mars Doughnut to those who show a NASA-issued Mars 2020 Perseverance “boarding pass” to redeem.

“The landing of Perseverance on Mars will be an epic and important achievement,” says Krispy Kreme chief marketing officer Dave Skena. “So, we’re celebrating the best way we know how: with an amazing new doughnut discovery right here on earth.”

When Perseverance lands in Mars’ Jezero Crater, it will have traveled 292.5 million miles since lifting off July 30, 2020 from Cape Canaveral Air Force Station in Florida. It contains the first-ever helicopter to be deployed on Mars and numerous other technologies to seek signs of ancient life and collect rock and soil samples. The rover also carries the names of nearly 11 million people who participated in NASA’s “Send Your Name to Mars” program.
