I spy with my little eye...
Continuing an epic summer of celestial photography, NASA released a stunning image of the International Space Station on Sunday. The shot, captured by agency photographer Bill Ingalls, shows the ISS flying across the face of the moon at a breakneck five miles per second.
There are currently six crew members on board the ISS, which orbits some 300 miles above Earth. The moon, meanwhile, is 238,900 miles away.
Ingalls has served as the senior contract photographer for the U.S. space agency for 27 years. You can see more of his stunning work on his personal website.
