Very cool!

Shouldn't there be some kind of shadow on the Earth (unless the moon just happens to be exactly in line with the Sun at this moment - which is actually close to being fully in shade according to my desktop moon calendar)?

Anyone know of anything else at L1?

My "epic" story, Bittersweet Seeds (which I plan to withdraw for a few months to finish the first draft), features in Act 3B a launch, trip, and arrival to a L1 space station for an intrasolar exploratory expedition launch and of course the grande finale.

The L1 point is between the sun and earth, so this satellite always sees the sun part of the earth.
The moon is very far away from earth, and you can only see it a few times.
One of the famous image (or movie) of the Moon in front of the Earth is from this satellite.

Don't you know that the top secret space base is on the dark side of the Earth? ;-)

Duh!!! Yes, it's right there in the title.

I was thinking L1 Earth-Moon. (I got too excited about seeing the L1 and thinking about my story.)

L1 Sun-Earth makes it much simpler for the lighting.

I know there are other things out there at that L1 too, such as solar imaging, early solar storm detectors, etc.
