PSA: Apollo 13 is currently marked as “Leaving Soon” on Netflix.

The scenes where they identify the square peg/round hole problem and where John Aaron and Ken Mattingly get the power draw down are some of my favorite in any movie. Must watch for any engineer

I love how their solution was not to fit the square peg into the round hole, but to use the suit air hose system to pull air through the filter instead.

They achieved the important function ("flow cabin air through the filter") in a totally different way.

I believe Neil Armstrong said that is the correct quote, it just dropped the "a" in the transmission.

There is a whole controversy and analysis about that particular syllable: https://en.wikipedia.org/wiki/Neil_Armstrong#First_Moon_walk Also, the blog post in the submission omits a major detail: the on-orbit docking maneuvers for the CSM to mate with the LM. A minor detail is that the Saturn V's third stage performed TLI (trans-lunar injection) and it actually impacted the Moon. After this TLI, the LM and the CSM wer…

At one point they discussed jettisoning the landing stage of the LM, for less mass so that the PC+2 burn would get them home faster, but most of the batteries and O2 tanks on the LM were in the descent stage (4 of the 6 batteries, I don't remember the distribution of the tanks) so dropping the landing stage made their other problems even worse. The landing stage stayed attached to the ascent stage for the entire life of Odyssey, and was dumped into a deep trench in the Pacific Ocean because there was a nuclear RTG to power the ALSEP attached to one of the legs of the lander.

We shake our heads at round vs. square filter in the distant 1970 past, but flash forward 55 years and we have that a very similar situation in the active American space capsules - none of the spacesuits are compatible with any of the other ships.

The Boeing spacesuit isn't compatible with the SpaceX capsule, which was recently an issue with the Crew 9 mission. And neither are compatible with the NASA Orion capsule.

Oh FFS... this guy went to the Moon and all people can argue about is what he said? How far we've fallen...

Many of us knew the story from books, or even the Tom Hanks Apollo 13 film, but the detail here is fascinating.

Also for anyone interested, some of Flight Director Gene Kranz's recordings are available online. Here's the first part: https://www.youtube.com/watch?v=KWfnY9cRXO4

The comments have time stamps for some particularly interesting moments, but the incident occurs 8 minutes in, and the infamous "Houston, we've had a problem" remark happens at 9:20.

The blog post talked about how everything had to be communicated verbally because you could not share images, but since we're so used to Hollywood adaptions or documentaries, I find the recordings really drive the point home.

Be glad people still believe anyone ever went to the moon at all. That may not be the case in a few more years.
