A New Hampshire auction house is soon accepting bids on a number of different space and aviation artifacts. Among them is an electrocardiogram of Apollo 11 Commander Neil Armstrong's heartbeat which was taken when he first arrived on the surface of the moon.

The RR auction will take place online from May 16 through May 23. The EKG reading for Neil Armstrong reportedly registered a normal heartbeat. Aside from the Neil Armstrong artifact, more than 85 lots of Apollo 11 material will be auctioned off. Some of the other objects include the joystick controller that Apollo 11 astronauts Michael Collins and Buzz Aldrin used in the Apollo 11 command module.

"There seems to be no end to the global appetite of collectors of this rare and historic material - especially from the amazing Apollo lunar landing missions," Bobby Livingston, Vice President, Sales & Marketing for RR Auctions, said in a press release. "The Great Space Race was truly a global event, and the collection of memorabilia and artifacts tied to that momentous moment in history is highly prized and sought after. RR Auctions is proud to be able to offer some of the finest and most interesting material available, and this assemblage is by far our most impressive since we began offering specialty aviation and space memorabilia auctions several years ago."

Neil Armstrong became the first person to walk on the moon on July 20, 1969. He was followed on the lunar surface by Buzz Aldrin. Neil Armstrong was originally from Ohio and died in August at 82 years old.
