Generally, beware of dissipating your powers, and strive to concentrate them.

Goethe, 1749

NASA Astronaut Scott Kelly shared this incredible video tonight, August 11, showing “our galactic home” with the stars of the Milky Way. Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world more than 220 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day conducting research about how the body adapts and changes to living in space for a long duration.
