Souvenir Sheet Honors Lunar Exploration
This Souvenir Sheet was issued to commemorate International Moon Day. Each UN issuing office released a set of four stamps and a sovenir sheet. The United Nations declared this day to be observed every year on July 20, the anniversary of the landing of Apollo 11 on the moon. The stamps in the set picture images from lunar missions from space agencies around the world.
The souvenir sheet features Luna 2, a Soviet Union rocket that was the first spacecraft to touch the Moon’s surface. The sphere-shaped space probe weighed about 860 pounds. It carried instruments to gather data concerning possible radiation on the Moon’s surface.
After several failed attempts, Luna 2 was launched on September 12, 1959. The following day, it crashed into the Moon, as the mission intended. Before landing, Luna 2 transmitted information back to Earth. As it was descending toward the Moon, it released a vapor cloud that could be seen by observatories in the Soviet Union. It was a way to track the spacecraft from the Earth. On impact, two spherical pennants contained in the spaceship were released. Each sphere was made up of 72 pentagonal discs, with an explosive charge in the center. The resulting explosion sent the discs flying in all directions. Each one had the emblem of the Soviet Union inscribed in it.
Despite the destruction of the space probe, Luna 2 sent more than 8.5 miles of teletype data back to earth. That was analyzed, then published the following spring. The mission’s success put the Soviet Union ahead of the US in the space race. The objective of America’s Ranger program was similar to Luna 2’s mission, but it wasn’t successful until 1964.
