    An Artist’s Vision of a Future Colony on the Moon

    Some time ago, I posted an image of the Copernicus Crater for the Astronomy Picture of the Week. Now I stumbled upon an amazing painting by Marshal T. Savage depicting his vision of a future colony on the Moon. It’s the same Copernicus Crater, except it’s domed over and terraformed to create an ecosphere. At first I thought that this was really cool, but it would be impossible to build such a gigantic structure. (The crater has a diameter of 93 kilometers!) However after giving it some thought I changed my mind. If it was built with a material strong enough like carbon nanotubes, it could in theory be built. While…

    Astronomy Picture of the Week – The Copernicus Crater

    Copernicus is one of the largest lunar impact craters on the visible hemisphere of the Moon. It was named after the Polish astronomer Nicolaus Copernicus. The crater is estimated to have formed about 800 million years ago during the Copernican period of lunar history, which was named after the crater. Copernicus is visible using binoculars, and is located slightly northwest of the center of the nearside, in eastern Oceanus Procellarum. The crater has a diameter of 93 kilometers and a maximum depth of 3.8 kilometers. Copernicus also has a dozen satellite craters ranging between 3 and 7 kilometers in diameter. By convention they share the name of the main crater…
