The moon must be molten all across its day side.

There was blue on the day side that looked like a sea.

That is the day side of what I have to tell you.

On the day side, half the atmosphere must already have been blasted away.

It was getting brighter as they now approached the day side.

Half the day side was hidden by the planet's bulge.

"Is your home on the day side or night side right now?"

It might have been on the day side during most of the scanning.

We made a quick swing of the day side, for a bare eyes look.

They were passing the day side, the planet nearly full.
