A desperate act of survival - 13 Minutes to the Moon podcast, Season 2, Episode 3

[@literallyshaking8019]

To me Apollo 13 was NASA’s finest moment. As incredible as a flawless moon mission is, keeping 3 men alive and bringing them home while facing such dire straits using creative, on the fly decisions will never fail to inspire me.

FYI at 9:02 this video has Jim Lovell as.a flight controller. This could not have been footage from Apollo 13.

[@AndrewBlacker-wr2ve]

He wasn't a flight controller but rather, cap-com. The astronauts for the next mission handled all the communications between Houston and the spacecraft. Good catch! (But... The video might also be from project Gemini because NASA had integrated the communications protocol before Apollo.)

[@spinav8r]

That is NOT Jim Lovell in that portion of the video you mention. I guess all NASA people look alike to you, huh.

[@codymoe4986]

While I agree that Lovell was CAPCOM on certain missions, the person at 9:02 is not Jim Lovell... Look again....

The statement around 18 minutes in about difference in position of the vehicles is wrong. 3m makes no difference. The problem was difference in ORIENTation. For instance the Z direction of the of the CSM is negative of the same vector for the LEM.

[@AndrewBlacker-wr2ve]

Very cool detail to point out! Would only the Z axis be backward but also the roll axes be inverse also? A starboard roll in the CM would be a port roll to the LM. Pitch axis should have remained same relative to the plane of travel. On Apollo 10, many times when the LM pulled up a new program to fly a routine in both the descent and ascent phases, activating the program caused the LM to lurch radically. I wonder if somehow orientation baselines were out of phase in the IMU.

@@AndrewBlacker-wr2ve First Para. It is a RH triad. Thumb is x Middle finger is Z. If you rotate your your R hand around to put Z down , Y remains in the same direction. X is at 180 degrees to where it was Therefore the direction of positive roll is reversed relative to the ship that is flying pointy end first. No comment on the second paragraph.

Wonder why the service module wasn't jettisoned early so the stack would be more fliable. _________ Also, i understand there's a bunch of trash floating around the CM and LM. But when the course correction burns happen, why doesn't the trash get shed and left behind.

[@spinav8r]

The service module was not jettisoned early because it helped protect the heat shield on the command module. Although the heat shield was designed to withstand extreme heating for several minutes during reentry into the Earth's atmosphere, it was not designed to undergo a few days worth of constant heating/cooling cycles that would happen while the spacecraft performed it's PTC (passive thermal control) rolling maneuver while in space. These heating/cooling cycles cause many expansion/contraction cycles that the heat shield was not designed for. The heat shield was absolutely critical to the high-speed safe return through the atmosphere, so no one was going to take any chances by jettisoning the service module early.
