Moon Landing 50 – The Other Watch of Apollo 11, The “Mission Control” Heuer Stopwatch


We thoroughly understand the Omega Speedmaster ‘Moonwatch’ , as the primary wristwatch on the Moon, which solidified its position in the set of experiences when the Apollo 11 mission effectively arrived on the Lunar surface on the wrist of Buzz Aldrin. Yet, there’s a generally secret Heuer stopwatch that assumed a little however vital part when Neil Armstrong was directing the lunar module “Hawk” to arrive on the Moon.

Since the underlying landing site was excessively enormous and rough, Armstrong needed to move the Eagle to an alternate area. This, consequently, made additional fuel be utilized and it had arrived at basic levels. In case of all fuel being utilized without a protected handling, a cut short would have been vital and hence no arrival on the Moon would have been possible.

For the Apollo 11 mission, Bob Carlton was the flight controller accountable for the lunar module and its control, direction and route systems.

The stopwatch he utilized was a Heuer and no doubt a variety of the reference 332.401 split seconds model. Vintage Heuer master, Jeff Stein of OnTheDash, has distinguished the model already here, on Chronocentric .

As you can see on the stopwatch utilized via Carlton, there are bits of tacky tape at specific positions. In the narrative Mission Control: The Unsung Heroes of Apollo (2017, by David Fairhead), Bob Carlton clarifies he set the tape at different spots to show time staying at stretches. You can see a few concentrates of this film (which we enthusiastically recommend) underneath, the watch being obvious and its job explained.

Gene Kranz, the flight chief gave a request that the lone radio communication to Armstrong while attempting to control the Eagle down, would be Carlton giving planning admonitions. You can hear Carlton on the official sound from the mission saying 60 seconds, then 30 seconds. He says in the narrative that when Armstrong had handled the Eagle, he halted the stopwatch and demonstrated that 18 seconds worth of fuel remained.

In 1978 NASA moved the stopwatch to the National Air and Space Museum of the Smithsonian. The Heuer stopwatch is right now in plain view in the Human Spaceflight show at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.

It may have just been a stopwatch, yet it assisted humanity with arriving on the Moon and, hence, it additionally is very special.
