Have you ever wondered which places on Earth most resemble other planets? For some of us, imagining the landscape of other worlds might just be for fun, but scientists and engineers wonder about what the otherworldly places on Earth can tell us about neighbors like the Moon and Mars.
Working in the most unusual places on Earth can help us to prepare for human flights, robotic missions and the search for life beyond our own planet. These analogues are chosen because they are similar in one way or another to particular planetary environments. They can be used for technical tests and research before the effort and expense of a launch into space.
Shift your perspective and imagine seeing the Earth from the outside; an alien planet in the vastness of space. If our photographs of Earth had been returned from robotic probes that had traveled for light years, how would you see them? From this perspective we can begin to experience the magnificence of the planet that is our home.

The art of meditation is neither mindless drifting on the one hand nor fearful clinging to the past on the other. It consists in being sensitive to each moment, in regarding it as utterly new and unique, in having the mind open and wholly receptive.
