Although this idiotic move by the Chinese government will demonstrate why we don’t want hit-to-kill ASAT testing in orbit—that will be a long-term recognition. In the short-term, the Chinese will simply not be credible partners in efforts to keep space peaceful. Moreover, other countries could follow suit with their own anti-satellite programs, including the United States.
UPDATE: Aviation Leak has picked up the story, too, here.
FURTHER UPDATE: The National Security Council confirms the test now, as well:
Using a ground-based medium-range ballistic missile, the test knocked out an aging Chinese weather satellite about 537 miles above the earth on January 11 through “kinetic impact,” … [NSC spokesman] Johndroe said.
