Any ECG in the ship? i saw a vid that show an ecg in the ship Jer10 95 05:10, 13 February 2007 (UTC)

In the space-suits, actually, I would think. ISTR reading that during the first landing, Armstrong's heart rate hit some amazing number, so they must have had telemetry on him, but I'm too lazy/busy to find the ref. Noel (talk) 22:13, 6 May 2013 (UTC)

Is the Apollo 11 LM photo correct?[edit]

The photo of the Apollo 11 LM Eagle in flight shows only 3 contact sensing probes. It is my understanding that Eagle had 4 such probes. Based on statements made by Neil Armstrong after the mission that the contact probe on the leg with the ladder could have (but didn't) obstructed access to the surface, subsequent missions removed the sensing probe from the leg with the ladder attached. Since the photo includes no probe on the leg with the ladder, this photo doesn't appear to be of the Apollo 11 LM, Eagle. --LESJet (talk) 02:21, 7 January 2013 (UTC)

Where and when did you see/hear Armstrong's comments? If he meant to imply that his LM did have the fourth probe, his memory must have mistaken. His flight was the first one on which the extra probe was removed. It wasn't just an issue of obstructing access, but of safety. They had to be careful about sharp objects like these probes, or antennas, puncturing the astronaut's space suits. The LM's on Apollo 9 and 10 had all four probes, but luckily someone must have given it some serious thought and didn't want Armstrong to risk being killed as he was taking his first step, from a puncture of his suit by the probe sticking out by the ladder! (Take a look at the surface photos available: the probes didn't go straight down through the soil; they bent sideways, or in some cases, even stuck up at an angle. Armstrong took enough pictures to clearly show the bent probes around the side and back footpads, but not on the front one.)
Eagle was also distinguished by the reddish thermal foil on the legs which didn't appear on the other LM's, and by the pattern of its black markings on the ascent stage, which again varied from LM to LM. Compare this photo with the ones taken on the lunar surface; that's definitely Eagle. JustinTime55 (talk) 14:20, 7 January 2013 (UTC)
I stand corrected! I double checked with the David Woods book and confirmed your statement above. Thanks for setting the record, and myself, straight. LESJet (talk) 02:14, 9 January 2013 (UTC)

Ascent Module thrust-to-weight-ratio[edit]

The article currently says "2.124 (in lunar gravity)". Given the stated APS thrust of 16 kN, gross mass of 4700 kg and lunar gravity of ~1.62 m/s^2, it should be 16 kN / (4.7e3 kg * 1.62 m/s^2) = 2.101, not 2.124 -- unless I'm missing something. — Preceding unsigned comment added by (talk) 04:10, 17 December 2013 (UTC)

Correction at "Masses" in Description[edit]

In should be "Total at beginning of Descent" "total at end of descent" and "total at ascent" the "total" in the Mass description its disturbing...
