Rocket explodes during testing at UK's new spaceport in Shetland

Lot of sats are for example spying sats, and these can use polar orbits (as the earth rotates under the sat, sat will at some point map the whole earth), or more fancy orbits that you can read about in this guide here: http://www.braeunig.us/space/orbmech.htm#types

⇒ they’re aiming for the part of the market where that doesn’t matter.

I honestly don't know why the Germans are trying to turn an old Chain Home radar station in the Shetlands into an orbital rocket launch site. For sun-sync polar orbits, it doesn't really matter what latitude you launch from, you aren't getting any benefit anyway, but I wonder at exactly how many of these sun-sync earth observing satellites are going to be launched by the ESA or Europeans in general. This doesn't seem like a particularly large market to me.
