The United States has released details of its latest test involving the interception of a missile target in space, part of what used to be called the Star Wars project.
It took place over the central Pacific Ocean on 15 March when a modified Minuteman Intercontinental Ballistic Missile (ICBM) was launched from Vandenberg Air Force Base in California.

The prototype interceptor was launched 20 minutes later 7,725 kilometres (4,800 miles) away from Kwajalein Atoll, in the Marshall Islands.

Ten minutes after the interceptor was launched, when it was at an altitude of 225 km (140 miles) above the Earth, it smashed into the target missile, destroying it completely.
