A unique piece of space memorabilia is hitting the auction block later this month—the first heartbeat on the moon. The electrocardiogram taken as Neil Armstrong set foot on the moon is among 85 Apollo 11-related items being auctioned, including the joystick used to control the module's landing, PC Magazine reports. New Hampshire auction house RR Auction has listed the EGK reading at $3,000, though its historical value may push it far higher, Space Reporter notes.
The most notable thing about Armstrong's heartbeat is that he stayed incredibly calm during the landing, says Gerald Schraber, who was monitoring the astronauts' vital signs at Mission Control. "It was really slow on the way down, while Aldrin's was racing, " he says. "But that was typical of Neil. Just like the first thing he really said was, 'Houston we have engine shutdown here,' really calmly. Mission Control told him to speak again. It was then he said, 'The eagle has landed,' for the TV networks. He was just that cool." (Read more Neil Armstrong stories.)
