SURPRISE! Green Day has become part of the latest unmanned mission to Mars. When the InSight probe landed on Monday, a chip featuring the words "Green Day Since 1986" etched on it was included inside the lander.
The band posted a picture on Facebook with the caption: “Officially landed on Mars. ‘Green Day Since 1986’ was etched on a chip on the NASA InSight lander that landed at Elysium Planitia today. Out of this world.”
No word on how they managed to get the engraving on the chip.
