Here's a good explanation of what an orbit around the second LaGrange point looks like, and (indirectly) why fears that Webb might be used to spy against earth are misguided.

Thanks for the link.

Until a couple weeks ago, I thought satellites just kind of bobbed up and down in Lagrange points, essentially fixed in place by their inertial momentum and by the competing gravitational pull of sun, Earth, and moon.

Until watching this, I did not understand what kind of orbit it would be in relative to Earth - polar or equatorial.

Amazing - much more complex and beautiful than I imagined.

If it all comes together and works, it will be the most amazing technological accomplishment in human history.

The idea that we may be able to see the first light after the Big Bang is almost incomprehensible.

I still do not conceptually understand how we are able to see light from a specific moment in time by looking deeper and deeper into space.

In my mind, 99.9% of all the light ever created has either already passed by Earth's current location, or is still traveling towards Earth's future location.

In my mind, every star we can see needed to be at an exact location relative to the speed and motion of that star and Earth, and relative to the expansion of the universe.

I have given up trying to understand it.
