The ISS had to avoid even more space junk for the second time in a week, highlighting growing concerns about crowding Earth's orbit.

For the second time in a week, the International Space Station has had to adjust its orbit in order to steer clear of a piece of approaching space junk.

The International Space Station was forced to shift its orbit to avoid hitting an oncoming "piece of orbital debris."

A Russian Progress freighter docked to the ISS fired its thrusters Monday (Nov. 25) to dodge a piece of debris, the second such evasive maneuver for the orbiting lab in less than a week.
