Build your own satellite

Honestly! It seems as if increasingly there is no activity that dedicated amateurs arent willing to have a go at. Formerly, building satellites was done by NASA and specialists like the Jet Propulsion Laboratory but thanks to greatly simplified design, called CubeSat, radio amateurs our building and launching their own communications satel lites into low Earth orbit. They even have their own governing organisation called AMSAT. So if you have a project that needs its own communications satellite why not build your own.

View declassified US satellite photos

Were all used to Google Earth and the phrase "large enough to be seen from space" has little meaning now when you can see my patio furniture on Google Earth. But, high quality satellite images have been generated since the 1960s. Many of these have been declassified and are available on the US Geological Surveys Earth Explorer website. These images are not restricted to the US - theyre spy photos so the whole world is pretty much covered. The interface takes a bit of figuring ou t but there are a lot of resources available on the site. Many researchers, such as archeologists, are finding these images very useful, as is reported in this National Gepgraphic article.
