#China’s #LongMarch6A is making a mess in #lowEarthorbit
The #upperstage from a Chinese rocket has broken apart in #space, creating a debris field of at least 700 objects in one of the most heavily-trafficked zones in #LEO. At this altitude, it will take decades or centuries for the wispy effect of aerodynamic drag to pull the debris back into the atmosphere. As the objects drift lower, their orbits will cross paths with SpaceX's #Starlink, #ISS and other crew #spacecraft

Debris Avoidance Maneuver 📆 Dec. 21 #trackingdata showed a close approach of a #fragment of #Russian Fregat-SB #upperstage #debris. It was #estimated that the debris could have passed less than a quarter of a mile from the station https://blogs.nasa.gov/spacestation/2022/12/21/space-station-maneuvers-to-avoid-debris-after-conjunction-postpones-spacewalk

".. Station conducted a Pre-Determined #Debris Avoidance Maneuver (#PDAM) today, Dec. 21, at 8:42 a.m. EST. The decision to conduct the maneuver was based on tracking data .. close approach to station of a fragment of Russian #FregatSB #upperstage debris."

".. Progress 81 thrusters fired for 10 min. 21 sec. .."

"Without the maneuver .. the debris could have passed less than a quarter of a mile from the station"
