Space Fence passes critical design review

Lockheed Martin's Space Fence System has passed critical design review.

The three-day test included the demonstration of "a small-scale system built with end-item components that detected and tracked orbiting space objects," according to a Lockheed Martin news release.

The Space Fence S-band radar system design, which will detect, track and catalog orbital objects in space more than 1.5 million times a day to predict and prevent space-based collisions, Lockheed Martin said.
