Apollo Anniversary Pop Quiz [Jul. 17th, 2009|09:47 pm]
A timely space quiz in honor of Apollo 11's fortieth anniversary. A few questions that may actually be a challenge and yield interesting answers. Enjoy!

1. What were the first statements transmitted to Earth after men first landed on the moon?

2. How long was it from when they touched down to when Armstrong actually took his famous step onto the moon?

3. Shortly after they touched down, Aldrin performed a personal ritual which may not have been fully sanctioned by NASA. What was it?

4. All the transmissions are filled with beeps at the beginning and end of statements. What are those?

"Here men from the planet Earth first set foot upon the moon, July 1969, A.D. We came in peace for all mankind." - Apollo 11's lunar plaque

1. They ran thru a short checklist of things, like 'engine off' and a setup for an emergency liftoff. THEN they did the 'Eagle has landed'.

2. If memory serves me correctly, it was about 3 or 4 hours before they got out. They actually were supposed to get some sleep in this time, but of course, they didn't.....

3. He said a prayer. Did he do a communion?

4. Because of the delay caused by the approx. 1.5 second light time one way, the beeps were there to help prevent people from talking over each other.

"Tranquility Base here. The Eagle has landed."

Hours. The landing was in the afternoon and the first step was after my usual bedtime.


PTT on/off noises so that they would not walk over each other with the second-and-a-half transmission delay and inspire legions of truckers to add the damn things to their CB radios.

They did originally have a nap scheduled but, as you pointed out, they weren't quite in a mood for sleeping. :)

I had always thought that too, about #4, but I've heard since that they were in fact there to switch remote transmitters on and off. They're called Quindar tones, if I remember correctly.

Ding! You even knew the technical name of Quindar tones. Well done.

1. Ding! The first things transmitted were:

"Okay. Engine stop. ACA out of detent."

2. ...even longer! :)

3. Ding! And, yes, he did take communion following a statement asking everyone to "give thanks in his or her own way." He'd brought up a miniature chalice, wafer, and water in his personal items pack.

4. A good guess and perhaps a secondary benefit, but not the original purpose. (And there are a number of occasions where you can hear astronauts talking over capcom and vice versa.)

I thought the first words were, "Holy s**t! We're on the f***ing moon!!!"

Soon to be followed by, "Last one out is a rotten egg!"

Yes. :D

I was also tempted to quote "From the Earth to the Moon," where the astronauts are discussing the upcoming mission and landing. [paraphrasing:]

Aldrin: "It'll be a defining moment when man sets foot on the moon."

Armstrong: "What do you think I should say?"

Collins: "If you had any balls, you'd scream, 'My God! What is that?' and cut your mic."

Are you following the LCROSS and LRO missions on Twitter and Facebook? It seems pretty silly to me, but it's also pretty fascinating that NASA is so hip with current technology.

And, at least I have the impact date in my calendar so I can watch out for it when it happens.
