The Progress 91 thrusters were fired at 6:10 p.m. EDT Wednesday for 3 minutes, 33 seconds, to raise the orbit of the International Space Station to provide an extra margin of distance from a piece of orbital debris from a fragment of a Chinese Long March rocket launched in 2005. The pre-planned Debris Avoidance Maneuver was coordinated by NASA, Roscosmos, and other space station partners.

Without the maneuver, NASA estimated the fragment could have come within around .4 miles of the station.

There is no impact to operations aboard the space station and it will not affect U.S. spacewalk 93 on Thursday, May 1, with NASA astronauts Anne McClain and Nichole Ayers.
