Heartbeats on the moon

What wonderful times we live in. Around the world, media houses are covering the 50th anniversary of America's mankind's moon landing, and all sorts of wonderful articles are being published, detailing otherwise un-heard of stories and anecdotes of that historic week. One such article is regarding how mission control at Houston tracked and observed the hearbeats and life stats of the three men onboard. Fascinating read  !

Also, the journal of the entire mission is online, in public domain, for anyone to peruse and research forever. They are sometimes too technical, but are sprinkled with jokes and light ribbing between the crew and Mission Control, even in the midst of stressful moments.

Armstrong later said he wasn’t worried about the fuel. They were close enough then that if the engine cut off, the moon’s gentle gravity, one-sixth that of Earth’s, would let them coast safely down. But the descent must have been some adrenaline rush to push the lunar commander’s heart rate to 150. Armstrong’s pulse began to climb after he turned off the autopilot and took the controls in his gloved grip. The fate of the mission was, quite literally, in his hands. Tens of thousands of engineers had helped get him here, but this last bit was up to him. That kind of responsibility would quicken anyone’s pulse.
