Spacelog Apollo 8

Loud and clear.

The TV look okay?

That's very good.

Welcome from the moon, Houston.

Thank you.

Houston, you're seeing a view of the earth taken below the lunar horizon. We're going to follow a track until the terminator, where we will turn the spacecraft and give you a view of the long shadowed terrain at the terminator, which should come in quite well in the TV.

Bill, what do you think?

I think the thing that impressed me the most was the lunar sunrises and sunsets. These in particular bring out the stark nature of the terrain, and the long shadows really bring out the relief that is here and hard to see at this very bright surface that we're going over right now.

You're describe—that's not color, Bill. Describe some of the physical features of what you're showing the people.

Apollo 8, Houston. We're not receiving a picture now. Over.

We're now coming on to Smyth's Sea, a small mare region covered with a dark, level material. There is a fresh, bright, impact crater on the edge towards us and a mountain range on the other side. These mountains are the Pyrenees.

Apollo 8, we're not receiving modulation on the signal; we do have SYNC.

Are you reading us? Apollo, Houston.

Apollo 8, we're reading you loud and clear, but no picture. We have no modulation.

Roger. We understand. Take a look now.

How about now? Apollo.

Loud and clear. Good picture.

What you're seeing has been cross—Smyth's Sea are the craters Castner and Gilbert, and what we've noticed especially, that you cannot see from the earth, are the small bright impact craters that dominate the lunar surface.

The horizon here is very, very stark. The sky is pitch black, and the earth—or the moon, rather, excuse me—is quite light; and the contrast between the sky and the moon is a vivid, dark line. Coming into the view of the camera now are some interesting old double ring craters, some interesting features that are quite common in the mare region and have been filled by some material the same consistency of the maria and the same color. Here are three or four of these interesting features. Further on the horizon you see the … The mountains coming up now are heavily impacted with numerous craters whose central peaks you can see in many of the larger ones.

Actually, I think the best way to describe this area is a vastness of black and white, absolutely no color.

The sky up here is also rather forbidding, foreboding expanse of blackness, with no stars visible when we're flying over the moon in daylight.

You can see by the numerous craters that this planet has been bombarded through the eons with numerous small asteroids and meteoroids pockmarking the surface every square inch.

And one of the amazing features of the surface is the roundness that most of the craters—seems that most of them have a round mound type of appearance instead of sharp, jagged rocks.

Only the newest feature is of any sharp definition to them, and eventually they get eroded down by the constant bombardment of small meteorites.

How is the picture now, Houston? Houston, are you reading us?

Loud and clear, and the picture looks real fine.

Thank you.

Can you see the two large craters just to the right of our track, Houston?

That's affirmative.

The very bright features you see are the new impact craters, and the longer a crater has been on the surface of the moon, why, the more mottled and subdued it becomes. Some of the —

Apollo 8, we've apparently lost your voice; the picture is still good.

Roger.

Houston, we're passing over an area that's just east of the Smyth's Sea now, in checking our charts. Smyth's Sea is coming up in a few minutes.

Roger.

Apollo 8, if you go to P00 and ACCEPT, we'll uplink some information.

We are now coming up towards the terminator, and I hope soon that we'll be able to show you the varying contrast of white as we go into the darkness. Houston, we're in P00, and you have the computer.

Thank you.

We're now approaching a series of small impact craters. There is a dark area between us and them which could possibly be an old lava flow.

You can see the large mountains on the horizon now ahead of the spacecraft to the north of our track.

The intensity of the sun's reflection in this area makes it difficult for us to distinguish the features we see on the surface, and I suppose it's even harder on the television, but as we approach the terminator and the shadows become longer, you'll see a marked change.

There is a very dark crater in the filling material in this valley in front of us now. It is rather unusual in that it is sharply defined, yet it's dark all over its interior walls, whereas most new-looking craters are of very bright interior.

Small impact crater in front of us now in the little mare well defined, quite new, and another one approaching. The spacecraft is facing North. From our track, we are going sideways to our left.

You are now seeing the Sea of Crises coming over the horizon.

We believe the crater, the large dark crater between the spacecraft and the Sea of Crises is Condorcet Crater. The Sea of Crises is amazingly smooth as far as the horizon and past this rather rough mountainous region in front of the spacecraft.

Apollo 8, we are through with the computer. You can go back to BLOCK, and it looks like we are getting a lot of reflection off your window now.

Roger. We'll switch windows; How does that look now, Ken?
