Moon Walkers.

Lest we not forget, as our mortality brings about "changes" and we find our "circuits dead",

We must "turn and face the strain" with the grins of all things past:

And the stars look very different todaaaaay.

I thought they couldnt see the stars from the moon?-->un less they looked through the optics as NA stated many times,but only that we know the view finders were removed from the cameras.

Two good song's but,i enjoyed them. But what do people from other countries sing about?.
How easy was that
The slow motion exit from the lunar lander,the foot print,the space suits,the lunar module and backdrops--all looks so real,and all done in a studio.
And do you understand the message behind the song?.

Tinman,

Which video regarding the moving flag are you guys going on about.  It's been buried in the thread, can you repost the link?

Regarding the flag versus temp thing, I'd be more concerned about changes due to UV and ionizing radiation.

They would, at the least, be very stiff and brittle I would think, likely bearing little resemblance to the US flag.  But with no atmosphere, a portion at the least could indeed still be hanging on.

The "oven test" would need to be done in a vacuum, or at the least, in an inert atmosphere...

Here is the video in question PW. From 2:30 on

Yes with the flag test being in a vacuum. Maybe with the use of a large spot light as the heat source?.
But the test was more to see at what the material temperature would have to be before it starts to shrivel up.

I have really enjoyed going through the high res pictures of the Apollo mission from this site--real or not,the pictures really make you want to believe that man did make this fantastic journey.
But i will not let !what may be! a wonderful fantasy get in the way of scientific proof-either way.
So for all-enjoy the high res pictures of all missions.

There was a few !!odd!! pictures i found with the Apollo 17 CSM.
The first is a picture taken from the lunar lander of the CSM. The part you see is the command module.
Now just to keep MH happy,i will not comment on what i see that is covering the command module.
The second picture is a close up of part of the first picture from the link i provided above. You can also see the photo reference number in the first picture,so as you can have a look your self at the exploded view of the picture. When you have found the picture in the gallery from the link i provided above,you simply click on that picture. When you do this,a smaller picture will be displayed. Click again on that smaller picture,and you whole screen will be filled with a HD picture--can take a few seconds before the picture becomes clean--depends on your PCU speed,and internet connection speed. Once you have the exploded view,you simply move your mouse over the picture to view different parts of the picture.

The third picture below is of the CSM in moon orbit. Now we see the CSM skin has a highly reflective surface. Remember-the first picture shows the CSM leaving earth heading for the moon,and the third show's it in orbit around the moon.
I will leave others to determine what they are looking at in the first picture.

I watched the video.  I believe the flag moved due to being hit by the exhaust from the spacesuit sublimator.

In the video, if you can stand listening to the sound track, you will hear NASA say "coming up on water".  The astronauts are being told there EVA must come to an end because the portable life support system (PLSS) is running out of water.

The PLSS used a rebreather and CO2 scrubber.  Oxygen, as a consumable, was rarely the limiting factor regarding EVA time.  However, the suits used a "sublimator" for cooling which consumed water and it was that water which was typically the EVA limiting consumable.

Somewhat simplified, the sublimator forces water thru very tiny pores on the inside of a cylindrical metal plate.  The water freezes.  Warm water from the suits garment layer needing to be cooled is run thru tubes in contact with the plate.  This "melts" and "boils off" (actually, "sublimates") the water (which does so at a lower temp in a vacuum).  A fan is used to purge (blow out) the water vapor from the inside of the cylindrical sublimator.

If I recall correctly, the exhaust for the sublimator is thru a relatively large circular opening in the left side of the PLSS hard shell.
