China changed a lot and of course North Korea not at all. Well, some people are attempting to sift more truth of […]Read More Finding the truth of a country’s economic state, from space
Okay, maybe not everywhere. But there are quite a few in the US according to Gizmodo in their article. 8 of them. I’m not as interested in “space tourism,” as I am in thinking this gives us some flexibility, if we’re smart about this, in replenishing satellite constellations. Not that I’d be against flying up […]Read More Spaceports everywhere!!
Two articles for the price of one in this aside. The Australians have figured out they can use their widefield array to help track debris orbiting the Earth, and that’s elaborated on (a little bit) in this article. This will help by adding another asset to the space situational awareness problem. It’s a bigger problem if […]Read More Space junk tracking and collecting
Imagery satellites have come a long way since the Corona/Discovery program. Nowadays, there is so much more an imagery bird can deliver—and that’s what DigitalGlobe is giving to its customers. Before going on, I just want to clarify my reasons, again, for covering DigitalGlobe in this series. Primarily, they make it easy to find things.

The nice thing about government satellites, and perhaps satellites generally, is they are in a high demand field. And there’s not very many to go around (a lot of people call this high-demand/low density, or HD/LD). Then it makes sense someone is trying to figure out how Kepler can still be used. In this case, […]Read More Kepler: looking at the bright side of life (in space)
