NASA calls this action “ A predetermined avoidance maneuver ”（PDAM）
Although the risk of collision with Russian space debris is not high , but NASA I still think that doing so will help open a safe distance between the space station and the debris flight path .
The agency is update message It is said that ： Astronauts have never been at any risk , This maneuver will not have any impact on the operation of the space station .
It is reported that , These fragments originated in Russia Cosmos 1408 The remains of . Russia is 2021 The failed satellite was destroyed in , But it also made about 1500 Pieces of space junk .
Although it will not have any direct impact on the operation of the international space station in the near future , But some experts warn that —— These fragments may be in the next few years , Potential risks to the international space station and other earth orbit projects .
ProgressMS20 performed an unplanned engine burn to avoid a space debris（via）
before , The international space station has been damaged by space debris . thankfully , This is not the case in this case , But it has more or less aroused people's concern about the increasing proliferation of space junk .
For decades, , Scientists have been looking for a solution , In order to avoid the risk to the relevant mission operation caused by the space garbage scattered everywhere .

Like recently , There is weight 3 Tons of space junk hit the side of the moon . If you don't control it well , There may even be more space junk hitting the moon or Mars in the future 、 Even put human life in danger .
Usually , Abandoned satellites will take re-entry and burn up 、 Or drop the debris into the inaccessible land and sea . But for those whose power has failed , Maybe we have to pay more for space salvage .
