Their work seems to identify a gap that civil local government services haven’t yet addressed: solving crimes using Earth Observation imagery. The company isn’t just focusing on capital crimes, such as murder (although this NewScientist story talks about […]Read More “Space Ventura,” Space Detective
Several days ago, I posted these two pictures with a vaguely worded question: https://themadspaceball.wordpress.com/2013/08/09/one-of-these-things/ I promised an answer to that question and here it is: the top picture was taken from low earth orbit (LEO), the bottom from geosynchronous (GEO) orbit. How can one tell from just the pictures? Two big telltales exist in them. […]Read More Pop Quiz answer

How can you tell there’s something space-y going on in your neighborhood? The most visible part of the ground system is the thing […]Read More Why space matters: Imaging satellite operations, part 7 (the dishy part)

So let’s start with the first challenge. A low earth orbiting (LEO) satellite is going around the Earth really quickly. There […]Read More Why space matters: Imaging satellite operations, part 6
