K-Corp Space Station

K-Corp Space Station was built in 2010 and put into standard orbit of the planet Earth in 2015. In the year 2083 this space station was repurposed into a radiation scrubbing machine which helped clean the planet's atmosphere. While it didn't do much in terms of cleaning the atmosphere, it was a vital piece of making the planet more habitable to regular human beings. It was also the planet's first defense against extra-terrestrial threats despite its limited capacity for weapons and offensive measures.
