Three CubeSats, with the Earth's limb in the background, are seen moments after being ejected from a small satellite deployer outside of the International Space Station's Kibo laboratory module on Wednesday, May 16, 2017. Over a dozen CubeSats were ejected into Earth orbit this week to study Earth and space phenomena for the next one to two years.
