* Analysis on all satellites seen by year's end

* Collision seen as seminal event

* Air Force analysis efforts still decades behind

WASHINGTON, Nov 3 (Reuters) - The U.S. military said on Tuesday it is
now tracking 800 maneuverable satellites on a daily basis for possible
collisions and expects to add 500 more non-maneuvering satellites by
year's end.

The U.S. Air Force began upgrading its ability to predict possible
collisions in space after a dead Russian military communications
satellite and a commercial U.S. satellite owned by Iridium collided on
Feb. 10.

General Kevin Chilton, commander of U.S. Strategic Command, called the
collision the "seminal event" in the satellite industry during the past
year and said it destroyed any sense that space was so vast that
collisions were highly improbable.

He said military officials had wanted to do more thorough analysis of
possible collisions in space, but had lacked the resources. Before the
collision, he said they were tracking less than 100 satellites a day.

"It's amazing what one collision will do to the resource spigot," he
told a space conference in Omaha, Nebraska.

The crash, which was not predicted by the U.S. military or private
tracking groups, underscored the vulnerability of U.S. satellites, which
are used for a huge array of military and civilian purposes.

Chilton said the Air Force was tracking more than 20,000 satellites,
spent rocket stages and other objects in space, up from just 14,000 a
few years ago.

But he said that was just what U.S. could "see" and there were estimates
that the actual number was much greater, posing a potential threat to
satellites on orbit.

Air Force Lieutenant General Larry James, who heads U.S. Strategic
Command's Joint Functional Component Command for Space, told reporters
the Air Force met its goal for tracking possible collisions among 800
satellites that have the ability to be moved in September, ahead of an
October target date.

"Our goal now is to do that conjunction assessment for all active
satellites ... roughly around 1,300 satellites ... by the end of the
year and provide that information to users as required," James told
reporters on a teleconference during a space conference in Omaha,
Nebraska.

Some of the 500 satellites still to be assessed cannot be shifted
because they do not carry extra fuel that would be needed to move them
once in orbit.

To increase its ability to predict possible collisions, the Air Force
has been buying more computers and hiring analysts. It also works with
commercial satellite operators to share data collected by their
spacecraft and by U.S. government sources.

Chilton lauded the efforts, but said the work was still too reliant on
Air Force analysts and needed further improvement. "We are decades
behind where we should be," he said.

Victoria Samson, with the nonprofit Center for Defense Information, said
the Air Force needed more trained operators to do the analyses and the
goal of adding 500 more satellites to the analysis might be "somewhat
optimistic." (Reporting by Andrea Shalal-Esa, editing by Alan Elsner and
