The General Assembly declared International Moon Day, a United Nations-designated international day to be observed annually on 20 July, in its resolution 76/76 on “International cooperation in the peaceful uses of outer space” in 2021.
International Moon Day marks the anniversary of the first landing by humans on the Moon as part of the Apollo 11 lunar mission.
The celebrations will also consider the achievements of all States in the exploration of the Moon and raise public awareness of sustainable Moon exploration and utilization.
For thousands of years, human civilizations have looked up to the sky pondering the origin and mysteries of the Moon – our only natural satellite. Ground-based observations enabled by the invention of the first telescopes opened a new chapter in our understanding of our celestial companion.
With the birth of space activities, the Moon became the ultimate destination of countless missions, including crewed flights that brought the first human footprints to another place in the universe.
As Moon exploration efforts continue taking shape with ambitious plans, this global celebration will serve not only as a reminder of success in the past, but as an annual testimony to future endeavours.
From the very beginning of the Space Age, the United Nations recognized that outer space added a new dimension to humanity’s existence. The United Nations family strives continuously to utilize the unique benefits of outer space for the betterment of all humankind.
Recognizing the common interest of humankind in outer space and seeking to answer questions on how outer space can help benefit the people’s of Earth, the General Asssembly adopted its first resolution related to outer space, resolution 1348 (XIII) entitled “Question of the Peaceful Use of Outer Space”.
On 10 October 1967, the “Magna Carta of Space”, also known as the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies entered into force.
Today, the United Nations Office for Outer Space Affairs (UNOOSA) is the United Nations office responsible for promoting international cooperation in the peaceful uses of outer space. UNOOSA serves as the secretariat for the General Assembly’s only committee dealing exclusively with international cooperation in the peaceful uses of outer space: the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS).
UNOOSA is also responsible for implementing the Secretary-General’s responsibilities under international space law and maintaining the United Nations Register of Objects Launched into Outer Space.
