WASHINGTON (Reuters) - The U.S.
Air Force said Friday it will be watching
closely for any damage to U.S
missile-warning, communications and
other military satellites when the earth
passes through the Leonid Meteor
Storm on Nov. 17.

The storm, consisting of tiny sand-like
particles traveling faster than 140,000 mph, is essentially
a cloudy tail of space debris from the comet
Temple-Tuttle.

Although there was some concern when the earth first
passed through the comet's tail in 1998, the Air Force
said scientists expect this year to be the largest display
from Temple-Tuttle since 1966.

"Air Force satellite operators are reviewing contingency
plans to protect and recover, if necessary, military
communications, missile-warning and navigation satellites
that could be affected by the storm," the Air Force said in
a statement.

The earth is expected to pass through the tail on Nov. 17.
While the fast-moving particles could cause mechanical
damage to satellites, they would be more likely to cause
electrostatic discharge -- or short circuits.

The Air Force said satellite operators may turn off
sensors, avoid commanding and controlling satellites
during the storm, or reorient satellites to provide a smaller
cross-section and mitigate the effect of the storm.

The Air Force Space Command is preparing to view the
storm from electro-optical facilities at the Maui Space
Surveillance Site atop Mt. Halaeakala in Hawaii. It will
be one of the prime viewing locations for this year's
storm, although other key viewing locations are in Israel,
Canada, Florida and the Canary Islands.
