The EKG shows the tense final minutes as Aldrin and Armstrong searched for a place to safely land the Eagle lunar module. According to those familiar with the EKG, it shows Aldrin’s blood pressure rising as the pair of astronauts began to run short on fuel.
Armstrong’s blood pressure remains relatively low as he scanned the lunar surface for an area clear of house-sized boulders. The pair of astronauts landed the lunar module in the Sea of Tranquillity on the surface of the moon with less than 20 seconds of fuel remaining.
RR Auction will take bids on the EKG during a series of auctions running until May 23. Other items include the joystick used to control the lunar module’s descent to the moon, and 85 other items from the Apollo 11 mission, according to The Space Reporter.
Armstrong, the first man to walk on the moon, passed away last year at age 82 due to complications arising from heart surgery.
