White Sands Missile Range will have their open house this spring, one of only two that happen every year.

For only two days a year, the New Mexico military facility that was once home to a secret weapons project opens to the public. The Army's White Sands Missile Range is where the very first atom bomb was tested more than 71 years ago.

On July 16, 1945 at 5:29 a.m., scientists tested the first atom bomb for the research and development program known as the Manhattan Project. The exact place is known as the Trinity site. A month later, an atom bomb was dropped on the Japanese city of Hiroshima and then later on Nagasaki. These bombs forced the Japanese to surrender and end World War II.

The Army's White Sands Missile Range opens the Trinity site to the public only twice a year, once in April and again in October.

On April 1st, people will be able to go to the Trinity site, located in the northern part of White Sands. The army shuts down some of the operations at the still active test facility so the public can have a chance to see where an important moment in history happened. Visitors are able to see the exact location where the bomb exploded, as well as the McDonald ranch house. The McDonald house has been restored to look exactly like it did back in the 1940's when the plutonium core was being assembled there.
