Space Is Close

Often when talking about distances in space, it’s difficult to wrap your head around how far things can be. ¬†Conversely, it can be difficult sometimes to realize how close other things are. ¬†Kottke points out just how close the definition of space is and relatedly, how close the space station really is.

A distance of 62 miles can covered by a car on the interstate in less than an hour. Stable Earth orbits are achievable at only 100 miles above the Earth, with the ISS and Space Shuttles usually orbiting at a height of ~200 miles. To show how small a distance that really is, I made the following image…the orange line in the upper left represents 200 miles away from the surface.
