Ladies and gentlemen, Green Day are floating in space.

Rather, Green Day floated in space and now they are chilling on the surface of Mars. The band revealed on Monday (Nov. 26) that a microchip etched with the phrase "Green Day Since 1986" was included in NASA's InSight Mars Lander, which touched down on the red planet's Elysium Planitia earlier that day. The phrase is a reference to the year the legendary punk trio was formed by then teenage pals singer Billie Joe Armstrong and bassist Mike Dirnt (then known as Sweet Children.)

"Officially landed on Mars," the group announced on their Twitter feed. "Out of this world."

A spokesperson for NASA tells Billboard that there were two chips included on the InSight lander that carried the names of more than 24 million people who submitted them during a public outreach campaign to help get people acquainted with the mission. "Each person who submitted a name could then download and print a 'boarding pass' with their name on it," the spokesperson said. The picture tweeted out by Green Day was their submission for the project. Among those who also participated were Star Trek legend William Shatner and Matt Damon; a spokesperson for Green Day could not be reached for additional comment.
