From an article by Meghan Bartels of Space.com:

The European Space Agency nudged one of its satellites from its normal orbit this week to avoid a potential collision with space junk, with the satellite soaring almost 400 feet (122 meters) above the risky object. But now, the agency needs to move the satellite back on track.

The operation comes less than a week after the agency released a new report about the huge amount of debris in space. That report found a total of almost 20,000 pieces of space junk in orbit as of the end of 2017 — more than 8,000 lbs. (3,628 kilograms) of dead spacecraft and their remnants.

On Monday (July 9), ESA controllers nudged CryoSat 2, which studies glaciers, higher up into Earth's atmosphere after scientists calculated that the satellite had more than a 1 in 10,000 probability of crashing into the piece of space junk, which the agency hasn't publicly identified.
