ロシアのミサイルテストからの破片が中国の衛星をほぼ攻撃する

A piece of debris created by Russia’s recent anti-satellite test came within striking distance of a Chinese satellite Tuesday, 中国政府が呼びかけた出会いで “非常に危険です。”

The Russian debris came as close as 14.5 メートル (約 48 足) from the satellite, according to the Space Debris Monitoring and Application Center of the China National Space Administration.
If a collision did occur, it could’ve caused ahypersonic shockwave,” said Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, who explainedit came close enough that it easily could have hit.
    A piece big enough to be tracked like this, it hits at 12,000 マイル/時, and you get a hypersonic shockwave going through the satellite that reduces it to shrapnel, to confetti,” 彼は言った.
      McDowell however, describes China’s assertion the two objects came within such a specific distance asnonsense because there’s no way they can know it that accurately.
        Based on publicly available US space tracking data, McDowell says the two objects could have come within anywhere from a few hundred yards to a few inches of colliding.
        The fact that it’s still there means it didn’t hit, but that’s the only way you know that,” McDowell said.
            Russia destroyed one of its own satellites last November in a direct-ascent anti-satellite missile test which has been condemned by US President Joe Biden’s administration as dangerous and irresponsible.
            当時の, US Space Command said the test generated “より多い 1,500 pieces of trackable orbital debris and will likely generate hundreds of thousands of pieces of smaller orbital debris.
