Could the Saturn V have had 9 F-1 engines instead of its 5. For more lift and payload capacity-possibly

No one talks about how clever the Apollo missions and all moon missions's names are. There is 2 current ones that I know of. Apollo, and Artemis. Both are named after celestial greek gods. Both fit perfectly. I want 2 other moon missions named Helios and Scelene so bad.

I've looked into why the Saturn V executed an 18 degree roll to align with the required trajectory etc. But one thing I have trouble with is seeing this manoeuvre in footage of the Saturn Vs taking off on the Apollo missions. I know it was an 18 degree roll and was wondering of anyone can point me to any footage of the manoeuvre? It's been bugging me for a long time now that I can't seem to spot it 🤣

So the last mission was in 1972 apollo 17 and nothing after that? Is there any specific reason for it and when is the next mission to land on Tranquility base.

Anyone know of a documentary series that documents all the lunar landings? Most seem to focus on Apollo 11 and 13. I would love to learn more about all the other missions, things like: what each missions goals were, the astronauts who embarked on them and some of the engineering challenges that were faced for each mission.

This is my Apollo CSM in 2/3 Scale. It was used in the Apollo 13 Movie in 1995 and hasnt been used since. I bought it 10 years ago and now it sits next to my planetarium. We hold lectures twice a week, especially focused on Kids and explain how rockets work and how big the universe really is. If you have any questions, feel free to ask!

The film Apollo 13 shows the CDR on the left, CMP middle, LMP on the right. This is at launch.

The film Fist Man shows them seated as CDR, LMP, CMP at launch

I’m wondering if the switch to direct rendezvous from coelliptic rendezvous for Apollo 14 had anything to do with the lunar rover. Obviously the rover wasn’t used on 14, but it seems possible to me the direct rendezvous approach was selected specifically because the savings in fuel mass would allow for carrying the rover, and that this approach was adopted for the Apollo 14 mission to prove direct rendezvous’ viability prior to sending the rover. In other words, the timing seems to line up (that having been said, I don’t know what the mission profile for Apollo 13 called for, coelliptic or direct rendezvous).

Does anyone know one way or the other?

Was his illness caused by the conditions? Or did he pick up a virus?

wonder what would have happened if the flight was normal and he was sick for landing/EVA.

Just realized it’s JY who awakens Mattingly to “get into the simulator“. And then the JY seems to defer to KM as the expert on the CM.

Couldn’t it be safe to assume that JY was more than an expert Ashe was CMP on 9 and well on his way to training as CDR on Apollo 16 (Though Not yet announced).

or was an earth re-entry from lunar orbit drastically different than a re-entry from earth orbit ?

ps. Is there any evidence ANY of the Apollo astronauts actually did sim work to help 13 return?

Look at 47:22 bottom middle/right. Bit confused!

Hi all,

I have looked for some information on this subject and have not been able to find much. I am curious as to how much time the astronauts on the Apollo missions spent in the LEM on the journey to the moon. Were the hatches on the doors open soon after they docked to the LEM? Did the astronauts use the extra space in the LEM to sleep/spend time? Or did they not utilize the LEM until soon before separation and landing on the moon?

I know that the LEM was jettisoned shortly after redocking so it was not utilized on the return journey, but curious if this was the case for the trip out as well.

Thanks in advance for any insight.

For those of you interested in diving a bit deeper into Apollo, I would highly recommend trying out Project Apollo - NASSP for Orbiter.

Orbiter is a free physics based space simulator and we have been developing NASSP (NASA Apollo Space Simulation Project) for many years and it's constantly evolving/improving!

This allows you to fly any of the Apollo missions as they were flown with the actual computer software and a very accurate systems simulation. We also have been working on the virtual cockpit in the CM and LM and they really outshine the old 2d version which if any of you are familiar with NASSP might know.

Additionally, users have been able to fly custom missions to other landing sites using the RTCC (real time computing complex) calculations, the possibilities are enormous!

We have an orbiter forum site here with installation instructions stickied. Additionally, we have a discord presence in the #nassp channel of the spaceflight discord:

Oh yeah, did I mention it's all free?

Feel free to ask questions here or drop by the forum and discord!

Also, those of you who do fly NASSP, please post your screenshots in this thread!

Ok..so the Apollo 13 movie is somewhat Hollywood-tized. sure..but still a fantastic movie.

But the one thing i did not understand one bit is during the return to earth after the course correction burn they came in just a bit to steep of an angle again for re-entry. The reason was they were expected to be hauling a couple of hunderds of pounds of moonrock which they obviously did not have. So the crew was asked by mission control to get some weight from the LM to the CM to put the angle a bit down?

I thought "what?" Does that make any sense or difference in a zero G emvironment? Did this actually happen?

(This might be a stupid question) I’m watching this new documentary about Apollo 13 on Netflix and I was wondering how did the astronauts move from the command module to the service module? Was that even possible?Considering that the bottom of the command module is covered with reentry heat shield. Was the service even accessible? Or was it just a compartment with engines and tanks and other rocket stuff not accessible to the astronauts?
