Apollo 13 Launch (Onboard Tape) 

Glad to be of service!!!

Next on my bucket list would be to hear the complete audio of Apollo 7, especially the spats between the crew and Mission Control.

i guess it is kinda off topic but does anyone know a good site to stream newly released movies online?

Scott Smyth which Saturn launch was that; which Apollo flight or what year?

In the late 90's I had a chance to see a shuttle launch. Nowhere near the thrust of the Saturn, but when it got past the tower, it was like continuous thunder. The feeling of the noise goes right through you. It's almost indescribable.

I am jealous. Wish I could have seen that.

Even future rockets will never hold up to this one. What they accomplished in such a frontier style timeline was simply amazing.

In the eyes of reality it is the biggest and the heaviest Rocket ever took off Earth's ground and went to space. And it is the most powerful successful rocket ever operated ! (The Russian N1 was unsuccessful unfortunately). What the new private companies are trying to built looks good big and powerful on paper. But in reality things are much more complicated! Look at space X test problems. and Northrop Grouman's OmegA's last rocket static test failure... No, it's not easy to build rockets and work successfully while launch you into the outer space to other planets! The SATURN / APOLLO program is for the ages...a unique mankind achievement that took the best of the best to make it real!

What really fascinates me is they built the Saturn V with paper drawings and slide rules and from the help of one woman who until recently I did not know who she was but thanks to the movie "Hidden Figures" Katherine Johnson a black genius math whiz now I know.

@@charlesalexander708 good film.

I second that.

Not too sure about that but thanks for the thought - regards LM5

lunarmodule5 There is so much nonsense on RU-vid. This is something educational and lasting for the world. This is important.

I totally agree with you on that. Lets hope it continues to be a resource for the near future... regards LM5

Yes! You even put in the small details like the ullage engines firing to settle the propellants during staging. Nice touch.

Me too - it was quite nice to do something different!

Yeah they basically invented computer, modern project management, requierment engineering, space travel, flight mission management, safety assessement on the same go. but what is less highlighted is that most of the engineers on the project did not see their kids growing up for a decade, several astronautes/pilotes died in the process and it used a noticable % of US GDP per capita. It was basically what human can acheive in a state of war when fight is on R&D not killing. And we have to keep in mind that this whole program was the German V2 lead combine with the Manhattant Project feedback. War is never far is most impressive human achievements

Great comment

They took too many liberties with the facts, IMHO. Younger folks not into all the real time broadcasts and transcripts will believe tye movie version over what really happened.

Welcome...glad you liked it regards LM5

yeah - you can hear the concern - and he says he didnt like that about 2 mins later too - regards LM5

@@lunarmodule5 Yep, 8:15 "Didn't like that inboard." [...engine quitting - uncommanded shutdown] But calm & apprehensive at the same time.

@@lunarmodule5 did they ever find out why the inboard quit early?

@@mauricefrontz8570 Pogo (like in a pogo stick) oscillations on the center engine. Actually came pretty close to tearing the booster apart, so the systems automatically shut it down. Thanks to the Level Sense system, it allowed the S-II to burn longer to compensate for the loss of the center engine. You can hear Jim mention something about some "funny vibrations" a short while after the center engine was cut off. The level sense system (I'm sure it was called something else) was a system which sensed (hence "level sense") the remaining quantity of fuel and oxidizer in the tanks, so that it wouldn't initiate staging before the propellants were below a pre-set level (thus allowing the S-II to utilize all of its propellants). So when CAPCOM Joe Kerwin (and all the other CAPCOMs on Saturn V flights) said "Level Sense Arm on" (and slightly before, the predicted time for that event) , the astronauts then knew that the system was on..

different target orbit

Welcome Peter

Welcome Howard - regards LM5

a single F1 engine of the 1st stage of the Saturn V rocket ( S-1C ) never failed! The S-II stage had that issue on the Apollo 13 flight.

I heard that the rocket may have exploded if it was not for that engine cutoff.

Hi MM - I only just found it - apparently its been there a while digitised - regards LM5

After this they started shutting it down early cause they realized the vibrations on #5 were so big it failed often.

Thank you tetekofa...i am glad you have enjoyed the channel content regards LM5

We debated long whose voice it was... convinced it was Skip...if you know it was Paul then i will accept it...now do i change the video... regards LM5

@@lunarmodule5 Not necessary-- It'll be our little secret....

Further researching this ...you are right...Skip stops after gdc align...Paul then comes in with the 30 seconds call...ty for pointing it out... LM5

LOL@ secret - FYI I have added a note in the description which explains the mistaken identity. I learn something new everyday! Regards LM5

I think most of us here actually read the comments too, so no need to reload the video with corrections.

More than welcome Gear

Thanks storm...it was fun to do! Regards LM5

Thanks gort...yeah and you can hear the cabin relieving and 1st stage too... regards LM5

Thanks ! Regards LM5

I am glad you are enjoying the channel Trevor ..please stay tuned for more to come regards LM5

Apollo 8 was the one that captured my attention. The first time being able to look up at the moon and imagine men circling it. Apollo 13 however had drama for several days so that did make it memorable.

They are abort modes...when the rocket was at specific points along the groundtrack ...specific modes would indicate which abort mode was in play at that particular time in the launch phase and therefore what had to happen.....from Wikipedia... Mode I: Abort using the LES, from launch until LES jettison 30 seconds after second stage ignition. Mode IA (one alpha): During the first 42 seconds (Saturn V) or 60 seconds (Saturn IB) of flight - up to 3,000 metres (9,800 ft) - the rocket is still relatively upright and an abort is much like a pad abort. The main and pitch control motors move the CM out of the flight path of the possibly exploding rocket. Fourteen seconds into the abort, the LES tower is jettisoned, leading to splashdown. Mode IB (one bravo): From 3,000 metres (9,800 ft) to 30.5 km (100,000 ft), the rocket is tilted eastwards far enough that firing the pitch control motor is unnecessary. After the LES main motor moves the CM away from the rocket, the tower would deploy canards (small wings at the tip). They would force the CM-LES combination to fly with the CM bottom forward (blunt-end forward or BEF attitude), necessary because the parachutes stowed at the CM top were only designed to be deployed in a downwind direction.[note 1] Mode IC (one charlie): From 30.5 km (100,000 ft, or about 19 miles) until the LES is jettisoned, turning the CM-LES combination around into the CM-forward position would still be necessary, but in the now thin air the canards are useless. Instead, the small engines of the CM's reaction control system (RCS) would do the job. During One-Charlie, the first staging occurs, that is the jettisoning of the spent first stage and ignition of the second stage. One-Charlie ceases about 30 seconds after the staging when the LES is jettisoned, at an altitude of about 90 km (295,000 ft or 55 miles). Mode II: With the LES gone, the Command/Service Module (CSM) would separate as a whole from the rocket and use its large engine and RCS engines to move clear of the rocket and align itself. The CM would then separate from the SM and splash down. Mode III: For use when a Mode II type abort would risk the spacecraft coming down over land, or landing in the cold waters of the North Atlantic. The CSM would separate from the rocket in the same manner as a Mode II abort, but would additionally use the SPS engine to make either a posigrade burn (Mode IIIA) or retrograde burn (Mode IIIB) to land in a specific area on the eastern side of the Atlantic. Mode III was only available as a primary abort mode for 10-15 seconds during a Saturn IB launch, and was only used as a backup abort mode for Saturn V launches, in case of an abort requiring the immediate landing of the spacecraft. Mode IV: Abort during S-IVB burn. Should the S-IVB fail, the Service Module engine can place the CSM in Earth orbit to perform an Earth-orbit mission. Mode V: Only planned for the Apollo-Soyuz Test Project launch. In the event of an early S-IVB shutdown, the CSM RCS thrusters would be used to insert the entire stack (including the docking adapter) into orbit. The time window for a Mode V abort was only 1.5 seconds before nominal S-IVB cutoff. For Saturn V launches, two additional abort modes were available: S-IVB to COI: ("Saturn IV-B (NASA's designation for the Saturn V's third stage burn) To Contingency Orbit Injection") In case of an S-II failure, the stage would be jettisoned, and the rocket is high and fast enough that the S-IVB stage, followed by the Service Module (SM) engine, has enough propellant to place the spacecraft in Earth orbit. There would not be enough propellant to perform trans-lunar injection, so only an Earth-orbit mission would be performed. S-IVB to orbit: The failing S-II would again be jettisoned, but Earth orbit insertion is now possible by the S-IVB alone. Other than not using the SM engine, this is identical to an S-IVB to COI abort. Hope that helps regards LM5

All i know is i have found 12, 17 and now 13...i know there isn't one for 11. Regards LM5

Its at archive.org/search.php?query=subject%3A%22Apollo+13+ACR+Collection%22 hope that helps LM5

You are welcome treebles - regards LM5

Glad u liked it F - regards LM5

Steve Steele - twice indeed but it was 8 & 13. One of the first three men to leave earth orbit and circle the moon, Christmas 1968. Borman, Lovell, & Anders.

8 and 13 you mean. Cernan was on 10 and 17

And Young was on 10 and 16!

They almost replaced Aldrin with Lovell on 11.

The audio is the tape that has been digitised. It has been digitised into several files, so I put them back together regards LM5

Thanks Maurice - regards LM5

The center engine on the S-II stage cut out 132 seconds early. The remaining 4 engines burned for an additional 34 seconds and the S-IVB engine required just under 10 seconds of additional burn to make up the required delta V. Luckily, there were enough redundancies in thrust to account for these off-nominal events. I recall Lovell saying that making it through this early engine cutoff should have been his one mission “hiccup” and he was glad to get it out of the way early in the flight. Little did he know what was in store for the crew at about 56 hrs MET.

"The Right Stuff" - It pretty much speaks for itself. You either have it or you don't. Before entering the Air Force, I thought anybody who wanted to fly could just fly - WRONG! LOL

It was the S2 - second stage - that had the engine shutdown way before it was supposed to - On both the Saturn V 1st and 2nd stages the center engine was shutdown about 30 seconds before the rest of the engines to relieve the G force and pressure of the rocket and get it ready for stage separation (reduce the force of that event). In this case the 2nd stage engine shut down early, which just meant that the other 4 engines had to fire for longer to make up for the decrease in thrust.

@@lunarmodule5 Thank you very much! It also confused me that Lovell was calling out such high g-loads after the inboard engine shut down, but that makes sense now if it was planned, and if it was intended to lighten the g-loads. I guess they were no longer fighting the atmospheric resistance so much by then. It just confused me knowing they had an early shutdown with S2, but not knowing about the planned early shutdown of the S1 inboard. I'm enjoiying your videos! We got so much animation from the networks during these Apollo launches, but it's nice to see some high-quality animation now :)

I imagine the LES would be tumbling a bit at this point....I have always thought that the LES sequence on the simulator leaves a lot to be desired... regards LM5

Hi IDK...am currently looking at finishing Apollo 12 which will take several months to complete...also, the MA7 audio isnt fully available at present. The only Mercury audio that is is MA8 so I will eventually get to that.. regards LM5

Thanks Dale

Ron Howard did a good job on the movie. I had the opportunity to see Fred Haise speak at the JSC in Houston, and as he tells it Howard had to use a good bit of drama to liven up the movie. After listening to the mission tapes, Ron Howard didn't get a sense of there being anything wrong! Everyone involved just worked the problems to get them home safely without all the drama we saw on the big screen!

I didn’t hear any tension between any of them.

@@Nick-wn1xw Agreed Jason

Yes

yeah! during launch the pressure has to be vented out from the capsule to mantain the differential pressure and to purge the nitrogen

When you have that much fuel burning right under your butt, well, they are actually pretty calm LOL

Simply put, the roll just aims the craft on the correct heading. They have to turn into the angle they need for their orbit, and also the correct heading depending on where they are going (orbit the equator, slingshot to the moon, etc)

Everyday Astronaut did a really good video about the roll maneuver. It's at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kB-GKvdydho.html

It didnt, Xiao

Yeah sorry...a literal interpretation. The only point of view film of the astronauts during Apollo is on the Apollo launch for ASTP...and it is hardly point of view...more looking at.

@@lunarmodule5 I was only disappointed for a goofy reason. I save little useful videos for the flat earth guys.
