Why space matters: Imaging satellite operations, part 12—all the colors of the rainbow—from space!!!

This lesson is not about space Skittles. Nor is it about any political parties or leanings within or without closets. The one thing I am asking you to do for this and the remainder of these imagery operations lessons, is keep in mind I am guessing. I don’t KNOW exactly how DigitalGlobe conducts their space […]

Why space matters: Imaging satellite operations, part 9–cutting the cheese

Hopefully the beer was tasty and nutritious. The question I posed in my previous post to you, dear (inebriated?) reader: Why is it that moving the plane of a satellite’s orbit against the direction of the Earth’s rotation (backwards) is helpful to those operators of imagery ilk? Let me clarify some terms here before we […]

Why space matters: Imaging satellite operations, part 8–synchronizing flying pumpkins and suns

Sorry, this isn’t about a tribute band for 90’s alternative/grunge music, at least not “Today.” This is all about polar orbits and polar sun-synchronous orbits. But before I get into those topics, let me warn you that if you delve too far into this, understand the math involved, the terms used, and worst of all worlds—enjoy […]

This image comes courtesy of the NASA Earth Observatory page. But it initially came to my attention from the Bad Astronomer page, […]

Why space matters: Imaging satellite operations, Part 5

One is a lonely number. It takes a while for one low earth orbiting (LEO) satellite’s payload (the camera) to see the entire Earth’s surface. If you want to get pictures more quickly, say the same day something like a hurricane or a forest fire is happening, you want a CONSTELLATION of satellites orbiting the […]
