This evening, the International Space Station’s Progress 81 thrusters fired for 5 minutes, 5 seconds in a Pre-Determined Debris Avoidance Maneuver (PDAM) to provide the complex an extra measure of distance away from the predicted track of a fragment of Russian Cosmos 1408 debris.
The thruster firing occurred at 8:25 p.m. EDT and the maneuver had no impact on station operations. Without the maneuver, it was predicted that the fragment could have passed within about three miles from the station.
The PDAM increased the station’s altitude by 2/10 of a mile at apogee and 8/10 of a mile at perigee and left the station in an orbit of 264.3 x 255.4 statute miles.
