Astronomy Fact
The sky is blue because when sunlight collides with our atmosphere, colors of the shortest wavelengths (violet and blue) are scattered - and our eyes are more sensitive to see blue.

Notes about viewing ESVs:
Best viewing is when ESV is in Earth's penumbra; on the map, it is the solid line during night.
Dotted line on map denotes ESV is dark, or, in Earth's umbra (shadow).
Objects in orbit have to maintain a speed of at least 17,500 mph, therefore ESVs traverse the sky noticeably different than aircraft.
ESVs appearing to blink are either tumbling rocket bodies, or spinning payloads with deployed solar arrays.
High-Eccentricity objects have a more ellongated orbit. Ground trace looks like a backwards "C".
Regression-Ground traces will move West with each orbit due to rotation of the Earth.
