Quiz: Landing on the moon

By | May 26, 2011, 1:50pm PDT

Summary: It was 50 years ago when President Kennedy challenged the nation to put a man on the moon and return him safely. Take this quiz and find out if you’re a rocket scientist.

On May 25, 1961, three weeks after the U.S. sent its first astronaut, Alan Shepard, on a successful suborbital flight, President Kennedy urged the nation and Congress to get behind his challenge of putting a man on the moon and successfully returning him to Earth by the end of the decade. At the time, the U.S. was lagging behind the Russian space program and deeply embroiled in the Cold War. The rest is history.

In light of Kennedy’s proposal, we invite you to take this challenge in his words (1962), “not because it’s easy but because it is hard.” We’ve also added a couple of questions about today’s space race.

Poll

Apollo 11's biggest scare on its descent to the lunar surface was the 1201 and 1202 alarms for the Guidance System computer that kept going off. What did this mean?

The correct answer is… »

Good day to confirm this comment I would appreciate T h e b e s t o f Z D N e t d e l i v e r e d your website very nice to everyone Yes, Oracle is the only one with shared-disk architecture, but that is there advantage. It means you can add or remove nodes and the database lives on. In a shared nothing architecture, if you lose a node, you lose the system. I'm sure Oracle appreciates EMC highlighting their advantage.I also desire to signal in your RSS feeds. Thank you as soon as once again and maintain up the great operate Awesome post! Thank you very much || thanks for nice content this is really benefit to me.

The correct answer should be "D". Not only did the explosion kill key scientists and the Cosmodrome, it destroyed the Russian version of the Saturn V or their "Moon Rocket".

Without that rocket, the Russians could never send a man to the moon and back.

So, perhaps it wasn't the explosion of the Cosmodrome but the rocket that exploded on the launch pad at the Cosmodrome that ultimately prevented the Russians from putting a man on the moon first and bringing him back safely.

@kenosha7777 The Cosmodrome explosion in Oct. 1960 which may have killed about 100 people was a setback to the Soviet space program but it was just 6 months later when the Russians achieved their greatest triumph - putting the first man in space. -Andy

The USSR got a man into space on an older and relible rocket. If that is the explosion I am thinking of, it was like trying to jump from a Redstone to a Saturn V. There was a glitch and some know-it-all general demanded that the rocket be repaired without defueling the vehicle. The story goes that he took a chair outside and sat down to make sure thing were done his way. I wonder if he saw the flash coming?

The first space shuttle accident occurred because the air temperature was too cold for the O-ring. The pad engineer was overruled by some bureaucrat and we all know what happened. The second shuttle accident happened because environmentalist policies forced a change of the insulating foam on the main booster. The new foam was more fragile and had a tendency to crumble and break during lift off.

The answer is "D". The computer was on overloaded because a radar that should have been turn off was left turned on.. Check the transcripts from the flight! I was watching the hole thing as it happened...

@rrance You are correct about the cause (switch turn on - see the answer) however the question refers to the error code which indicated the computer was overloaded and rebooting. Also note Answer D refers to a programming error - it was not, it was a human error.

I'm with k7777 that the explosion is often cited as the turning point.

Also, no one is making trips to the moon for H3 or any of the choices. It's purely research at this point. There are some plans about robotic mining of gold but very preliminary.

You state that the answer is "A" but the correct answer would be mostly "D". Why? The AGC never rebooted even once. What really happened is complicated but was partly caused by Buzz Aldrin being granted (during training) permission to keep the rendezvous radar switched on "just in case they aborted the landing". This added a computational overload which didn't allow enough time for the computer to complete all of its tasks, although it was able to complete its high priority tasks. Alarms 1201 and 1202 are labeled "executive overflow" and indicate "I am not completing all of my tasks". Starting with Apollo 12, the rendezvous radar was switched off until needed.
