A controversial effort by the US Pentagon to develop ground-based anti-satellite lasers has been highlighted by Congressional hearings held this week.

This facility was previously the subject of a New York Times article which argued the Bush Administration was pursuing anti-satellite laser weapons under the cover of astronomy.
