Neil Armstrong's moon heartbeat EKG up for auction

An electrocardiogram of Apollo 11 Commander Neil Armstrong’s heartbeat, taken when he first set foot on the moon, is set to go under the hammer.

RR Auction, which is based in Amherst, Massachusetts, will take bids on the EKG- that registered a normal heartbeat- and other artifacts during an online auction from May 16 through May 23, the Fox News reported.

Other artifacts include the joystick controller operated by Apollo 11 astronauts Buzz Aldrin and Michael Collins in the space flight command module.

According to auction officials, over 85 lots of Apollo 11 material will be featured in the auction.

Armstrong, who died in August at age 82, took his “giant step for mankind” on July 20, 1969.
