[Duke - "I was running more in Intermediate (cooling); and I could feel a hot spot...The right (side) PLSS strap was tight, compressing the insulation in the suit, and I could feel the Sun in there. With the higher angle (46 degrees at the time), we were running mostly in Intermediate, here."

EASEP Dust, Thermal,
and
Radiation Engineering Measurement Package.
This package
included
two temperature sensors. The dip in the
measurements before local
noon was the result of shadowing by other parts of the
EASEP.
According to the experimenters, this shadowing may have
casued the
maximum value recorded to be about 5 to 10°
C less than
what would have been measured had the shadowing not
occurred. |

Temperatures in the Lunar
Ejecta
and Meteorites experiment. The explosive packages
deployed by the
crew were detonate at the indicated sun angles during
the first
lunation, beginning about 24 hours after LM
liftoff. The LEAM
mirror covers were not removed until well after the last
of those
detonations. Differences between the temperature
profiles
measured on successive lunar days are ascribed to dust
accumulation at
local dawn and sunset. Evidence for signifcant
dust lofting at
those times is not yet compelling but, clearly, the LEAM
temperatures
should be used with caution. See a discussion in Section 15.4.3 in the
Apollo 17 Mission
Report. |

Notes |
Apollo 11 |
109:23:10 |
Did not experience
anything that
felt either hot or cold to the touch. |
Armstrong (from the Tech
Debrief) - "There weren't any temperature effects noted
in the egress
or (on the) ladder. Nothing felt hot or cold or
had any
temperature effects at all that I was aware of." Aldrin (from the Tech Debrief) - "In confirmation of Neil's findings, I didn't experience any hot or even warm spots in the suit." |
Apollo 12 |
117:07:05 |
Heat felt from plutonium
fueled
RTG |
Bean (from the Tech
Debrief) -
"I did notice, however, that you could
feel the heat radiating from the RTG. When I removed the
bracket that
carried the power cable that ran from the RTG to the
Central Station,
it felt warm to the touch. I didn't want to keep my
fingers there too
long, so I handled it with the ALSEP tool (UHT) as
opposed to just my
gloved hands, as I had been doing in practice.
Apparently that bracket
can get pretty hot, although we only had the element in
it a short
time." Conrad (from the Tech Debrief) - "I guess the point is, when you fuel that generator, you had better get on the road and get going to wherever you are going to take it. You should get those parts off the fuel element as soon as possible, because they heat at quite a high rate. |
Apollo 12 |
118:35:53 |
Metal tools warm to the
touch |
Bean (from the Tech
Debrief) -
"A couple of things I noticed as we worked was that, whenever I held onto metal tools for any length of time - anything shiny like the extension handle, the tongs or, later, during the second EVA, when I was carrying the Hand Tool Carrier - my hands would get warm. If I would put them down and remove my hands from them, my hands would get cool again. It was not too hot to handle; it was just the fact that I would notice they started to warm up." See, also, real-time discussion during EVA-2 at 133:15:10. |
118:38:12 |
Keeping rock box seals
warm |
At the end of EVA-1, they
put
the EVA-2 rock box in the Sun in the north foot pad to
keep the seals
warm, but covered it with the S-Band thermal protection
blanket.
"We didn't want it to get really hot." |
|
Apollo 15 |
148:39:34 |
EVA-2 rock box "very
warm" to
the
touch in the cabin |
Jim's photo AS15-87-11796,
taken at about 147:19:33 shows the rock box on the MESA and in sunight. |
166:50:32 |
Dave touches something
that
feels hot. |
"Something I touched was
hot -
through the suit, so it must have been pretty hot." |
|
Apollo 16 |
148:18:55 |
Houston notices the
thermal flap
on Charlie's OPS is open |
Houston is concerned
that, once
they get back in the cabin and get their gloves off,
Charlie's OPS may
be hot to the touch. Once they are back in the
cabin, Tony
reminds John of the possibility as he's taking his
gloves off at 150:05:56.
John
reports that the OPS is "cool as a cucumber". |
170:06:09 |
Cosmic Ray Experiment |
John mentions that the
plate on
detectors in the CRE won't pull out of its frame.
This was
undoubtedly due to thermal expansion. At
170:08:02, as John and
Charlie are each holding an end are trying to pull the
CRE apart,
Charlie can feel the heat through his gloves, "This
thing is hot, I'll
tell you". |
|
Apollo 17 |
148:24:59 |
In the cabin after EVA-2,
Jack
touches something 'hot' |
The circumstance suggest
that it
is the metal controls and fixtures on Jack's RCU.
During the
drive back from Station 5, the RCU's would have been in
full sun.
See, also, comments after 170:53:02. |

Apollo 15 |
Television Control Unit
(TCU) Elevation-Control Clutch Slippage |
Apollo 15 Mission Report
Section 14.5.1 |
The clutch was designed
to
operate at temperatures up to 122°F
(50°C)
but probably experienced temperatures inside the housing
of up to 180°F
(82°C). The clutch was redesigned
to eliminate
temperature-sensitive elastomers. |
Apollo 16 |
Cosmic Ray Experiment
Disassembly during EVA-3 close-out |
170:06:09 |
This anamoly is not
discussed in
the mission report, possibly because this design was not
going to be
flown on Apollo 17 and because, working together, John
and Charlie
managed to pull the detector plate out of its frame by
brute force
after two minutes of effort. |
Apollo 16 |
Far-UV (Astronomical)
Camera
Azimuth Adjustment |
Apollo 16 Mission Report Section 14.4.9 |
The UV camera was kept
the LM
shadow to protect the film from high temperatures.
The
grease used on the azimuth bearing had not been
tested in a cold
chamber. Under conditions in the LM shadow,
the grease
stiffened and John had so much difficulty turning the
camera between
exposures that, as he tells Houston at 143:19:40,
it was easier to pick the camera up, re-orient, and
re-level it than to
to use the azimuth adjustment. |
Apollo 17 |
SEP Receiver |
Apollo 17 Mission Report Section 15.4.2 |
The SEP receiver was
mounted on
the Rover behind the LMP's seat, inside a Kapton bag
designed to
provide thermal and dust protection while the Rover was
in
motion. At each stopping place, two covers on the
top of the bag
could be opened to expose a radiator mirror on the top
of the receiver
and allow cooling. Adhesive holding Velcro patches
used to secure
the cover flaps had already failed by the time Jack
configured the
receiver late in EVA-1. This allowed dust to
accumulate on the
radiator mirror and, although Gene and Jack repeatedly
dusted the
mirror, enough dust remained that the receiver
overheated. Little
useful data was obtained. (Note that a similar adhesive
failure had
occurred on Apollo 16 and it is unfortunate, to say the
least, that the
lesson wasn't applied to the SEP experiment.) |
