U.S. official: Chinese test missile obliterates satellite
POSTED: 0406 GMT (1206 HKT), January 18, 2007
WASHINGTON (CNN) -- China last week successfully used a missile to destroy an
orbiting satellite, U.S. government officials told CNN on Thursday, in a test
that could undermine relations with the West and pose a threat to satellites i
mportant to the U.S. military.
According to a spokesman for the National Security Council, the ground-based,
medium-range ballistic missile knocked an old Chinese weather satellite from i
ts orbit about 537 miles above Earth. The missile carried a "kill vehicle" and
destroyed the satellite by ramming it.
The test took place on January 11.
Aviation Week and Space Technology first reported the test: "Details emerging
from space sources indicate that the Chinese Feng Yun 1C (FY-1C) polar orbit w
eather satellite launched in 1999 was attacked by an asat (anti-satellite) sys
tem launched from or near the Xichang Space Center."
A U.S. official, who would not agree to be identified, said the event was the
first successful test of the missile after three failures.
The official said that U.S. "space tracking sensors" confirmed that the satell
ite is no longer in orbit and that the collision produced "hundreds of pieces
of debris," that also are being tracked.
The United States logged a formal diplomatic protest.
"We are aware of it and we are concerned, and we made it known," said White Ho
use spokesman Tony Snow.
Several U.S. allies, including Canada and Australia, have also registered prot
ests, and the Japanese government said it was worrisome.
"Naturally, we are concerned about it from the viewpoint of security as well a
s peaceful use of space," said Yashuhisa Shiozaki, chief cabinet secretary. He
said Japan has asked the Chinese government for an explanation.
The United States has been able to bring down satellites with missiles since t
he mid-1980s, according to a history of ASAT programs posted on the Union of C
oncerned Scientists Web site. In its own test, the U.S. military knocked a sat
ellite out of orbit in 1985.
Under a space policy authorized by President Bush in August, the United States
asserts a right to "freedom of action in space" and says it will "deter other
s from either impeding those rights or developing capabilities intended to do
so."
The policy includes the right to "deny, if necessary, adversaries the use of s
pace capabilities hostile to U.S. national interests."
Low Earth-orbit satellites have become indispensable for U.S. military communi
cations, GPS navigation for smart bombs and troops, and for real-time surveill
ance. The Chinese test highlights the satellites' vulnerability.
"If we, for instance, got into a conflict over Taiwan, one of the first things
they'd probably do would be to shoot down all of our lower Earth-orbit spy sa
tellites, putting out our eyes," said John Pike of globalsecurity.org, a Web s
ite that compiles information on worldwide security issues.
"The thing that is surprising and disturbing is that [the Chinese] have chosen
this moment to demonstrate a military capability that can only be aimed at th
e United States," he said.
