For space-nerds (RIP Denny) and of general interest the S-IVB (the third stage of the Saturn V) that propelled the CSM and LEM into TLI (trans-lunar injection) was no longer needed once they were on their paths to the moon so NASA intentionally crashed them onto the moon's surface to test out the seismometer's left by previous missions/probes. The LRO has imaged these impact sites, kinda cool IMO, also a chart of impact velocity and location data here.

Moon landing was an inside job, spent rocket stages can't melt cheese soil.

On serious note that is actually pretty cool! Been playing Kerbal Space Program, I managed to do something similar, except with an astronaut. He did not survive. I don't think I had enough fuel to make it back anyway. :biggrin:

Playing that game makes me realize just what really must go into making space flight possible though, all the planing, the calculations, the fail safes, etc... It's really incredible.

Here's another view of some of the sites.

Cool, I always found it amazing that #12 managed such a precise landing they were able to walk over to a Surveyor probe that had been there 3 years and remove parts from it so they could be examined back at the JPL labs. Even more amazing was #12 was struck by lightning TWICE wile still in 1st stage burn. Everything either went off-line or was flashing alarms and an abort was almost done when a young engineer told the crew to switch to backup power and from there everything eventually got brought back up. It's a testament to the robust design of the Saturn V that it's guidance systems never faltered and it got them into a perfect orbit without missing a beat. God hurled his mightiness power but the Sat V just shook it off like "fuck you, that's all you got bitch?" LOL.

During all of this, John Aaron was watching from his EECOM station, which monitors the vehicle’s fuel cells and cabin pressure. As his mind turned over, Aaron recalled a test from more than a year earlier of a system inside the command module that was used to power up the spacecraft on the ground. His mind clicked. When Flight Director Gerry Griffin asked him how his systems were looking, Aaron responded cooly, “Flight, EECOM. Try SCE to Aux.”

Griffin had never heard of that switch before. He didn’t know where it was located. And in the middle of this chaos, Griffin was worrying mostly about when the best time to abort the mission might be. “Say again? SCE to Aux?” Griffin said. But he trusted his flight controller implicitly, so without further hesitation, the instruction was passed up to commander Pete Conrad inside the capsule. Conrad didn’t know where the switch was either, but Alan Bean did. He flipped it. Data came flooding back into Mission Control, and they were able to reconnect fuel cells to the spacecraft.

Aaron had saved the day. “That’s the only mission we can think of where a single individual made that kind of a call,” Heflin said.

After the incident, the great Chris Kraft, the original flight director who had written most of the original rules for mission control, came into the room. Aaron soon felt a hand on his shoulder. “That was a great job, young man,” Kraft told him. There was no higher praise, from no greater man, for someone working inside Mission Control.

Yea, talk about "the right stuff" and he was all of 23 to boot!. Not only did he restore the data link he saved the US taxpayer a cool $450,000,000 with that call. Once the command module was clear,(via the launch escape system) the Sat V would have been destroyed by the range safety person. The guidance system, (housed in a ring at the top of the 3rd stage) was unaffected by the strikes. There was concern that the pyrotechnic system used to deploy the parachutes could have been affected but this was not relayed to the crew as there was no way to do anything about it if that was the case. Luckily it was OK because without it your hitting the water @ 300MPH, ouch.

My only contribution to this thread are pics at Kennedy Space Center. :awe:

Saturn V (363-foot rocket; diameter is 33 feet)
During the 1st (of 3 stages)... "the five F-1 engines propelled the spacecraft to a speed of 5,000 MPH and consumed fuel at a rate of 15 tons per second. Approximately 2.5 minutes after launch, the engines cut off and the stage was jettisoned into the Atlantic Ocean."

Launch Pad 39 (can't remember if it was 39-A or 39-B)

The actual Firing Room Theater used on Dec. 21, 1968 for the launch of Apollo 8 (the first mission to orbit the moon and the first manned flight of the massive Saturn V).

Still the most amazing thing ever built by humans.

Really puts into perspective today's society with their spinning rims and iPhones...

The thrust-plate must have been one heavy-duty chunk of steel, it had to absorb the 7.5 million lbs generated during liftoff and even more amazing was the outer 4 engines were hydraulically gimbale'd as well, the guidance system moved them to keep the giant rocket on course. Mike Collins was on record as saying he could feel them in action, Jesus what a ride that must have been.
