Good Month For Spaceship Spotting

May is a good month for spaceship spotting. The International Space Station has begun a 4-week series of bright flybys over North America and Europe.

In early May, the ISS joins Jupiter and the stars of the Summer Triangle in a glittering pre-dawn sky. Later in the month, increasingly-frequent flybys shift to evening hours and the ISS will be crossing paths with Saturn, the Moon and Mars.
