Apollo 11 was a spaceflight conducted from July 16 to July 24, 1969 by the United States and launched by NASA. It marked the first time that humans landed on the Moon. Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module Columbia in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes, before lifting off to rejoin Columbia.
The Space Race was a 20th-century competition between the Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II and the onset of the cold war. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, particularly in regard to intercontinental ballistic missile and satellite reconnaissance capability, but also became part of the cultural symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic landers to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon.
The Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a multilateral treaty that forms the basis of international space law. Negotiated and drafted under the auspices of the United Nations, it was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, entering into force on 10 October 1967. As of March 2024, 115 countries are parties to the treaty—including all major spacefaring nations—and another 22 are signatories.
Space law is the body of law governing space-related activities, encompassing both international and domestic agreements, rules, and principles. Parameters of space law include space exploration, liability for damage, weapons use, rescue efforts, environmental preservation, information sharing, new technologies, and ethics. Other fields of law, such as administrative law, intellectual property law, arms control law, insurance law, environmental law, criminal law, and commercial law, are also integrated within space law.
Compared to other objects in the Solar System, the Moon has many advantages that makes space colonization valuable and profitable. A spacecraft from low Earth orbit can easily land on the Moon's surface and withstand its vacuum-like conditions. The Moon also has natural resources available for in situ resource utilization such as abundant solar power, oxygen, water, metals and rare-earth minerals. The Moon also has a low gravity, no atmosphere and no ecosystem that can be destroyed, which is an ideal environment for profitable mining, manufacturing, and space launch industries to develop.
The Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, better known as the Moon Treaty or Moon Agreement, is a multilateral treaty that turns jurisdiction of all celestial bodies over to the participant countries. Thus, all activities would conform to international law, including the United Nations Charter.
Apollo, also called the Apollo basin, is a large impact crater located on the far side of the Moon, in the southern hemisphere. It was previously known as Basin XVI; in 1970 it was officially named after the Apollo missions by the International Astronomical Union.
Asteroid mining is the hypothetical extraction of materials from asteroids and other minor planets, including near-Earth objects.
The following outline is provided as an overview of and topical guide to space exploration.
A moonbase is a human outpost on or below the surface of the Moon. More than a mere site of activity or temporary camp, moonbases are extraterrestrial bases, supporting robotic or human activity, by providing surface infrastructure. Missions to the Moon have realized single-mission bases,, as well as some small permanent infrastructure like lunar laser ranging installations.
Space-based economy is economic activity in outer space, including asteroid mining, space manufacturing, space trade, space burial, space advertising and construction performed in space such as the building of space stations.
The Center for Air and Space Law at the University of Mississippi School of Law has been the premier U.S. platform for Air and Space Law since 1965. It is the only American Bar Association accredited law school to offer an LL.M., a JD Concentration and a Graduate Certificate in Air and Space Law. The core of the space law program was built by Stephen Gorove, one of the earliest jurists to focus on legal aspects of space exploration.
The politics of outer space includes space treaties, law in space, international cooperation and conflict in space exploration, international economics, and the hypothetical political impact of any contact with extraterrestrial intelligence.
In archaeology, space archaeology is the research-based study of various human-made items found in space, their interpretation as clues to the adventures humanity has experienced in space, and their preservation as cultural heritage.
The space policy of the United States includes both the making of space policy through the legislative process, and the implementation of that policy in the United States' civilian and military space programs through regulatory agencies. The early history of United States space policy is linked to the US–Soviet Space Race of the 1960s, which gave way to the Space Shuttle program. At the moment, the US space policy is aimed at the exploration of the Moon and the subsequent colonization of Mars.
Lunar tourism may be possible in the future if trips to the Moon are made available to a private audience. Some space tourism startup companies are planning to offer tourism on or around the Moon, and estimate this to be possible sometime between 2023 and 2043.
For All Moonkind, Inc. is a volunteer international nonprofit organization which is working with the United Nations and the international community to manage the preservation of history and human heritage in outer space. The organization believes that the lunar landing sites and items from space missions are of great value to the public and is pushing the United Nations to create rules that will protect lunar items and secure heritage sites on the Moon and other celestial bodies. Protection is necessary as many nations and companies are planning on returning to the Moon, and it is not difficult to imagine the damage an autonomous vehicle or an errant astronaut—an explorer, colonist or tourist—could to one of the Moon landing sites, whether intentionally or unintentionally.
The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that, together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond.
The Artemis Accords are a series of non-binding multilateral arrangements between the United States government and other world governments that elaborates on the norms expected to be followed in outer space. The Accords are related to the Artemis program, an American-led effort to return humans to the Moon by 2027, with the ultimate goal of expanding space exploration to Mars and beyond.
