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 […]

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 […]

Why space matters: Imaging Satellite Operations, part 4

Okay, you’re holding the orange in your hand again (I hope you haven’t been holding it all this time—it’s been a few days). Again, there’s a line drawn around the orange that is parallel to the ground. The line represents…(you should be thinking the words “the Earth’s equator”). Now, roll the coin perpendicular to the […]

Why space matters: Imaging Satellite Operations, Part 3

So, assuming you’ve been tagging along this far, now we know that a good low earth orbit (LEO) for taking pictures is around 313 miles. But there’s another question that needs asking: what’s the best LEO (aside from your dream date) for ensuring you will eventually get to take pictures of Earth’s ENTIRE surface ? This […]

Why space matters and explaining imaging satellite operations, Part 2

In Part 1 of explaining imaging satellite operations, we assumed a low earth orbit (LEO) satellite is one of the better options for getting great “Earth-selfies” with a camera on board. We also learned the range of LEOs is pretty big: 99 to 1200 miles. But we also know closer is mainly better (see previous post […]
