The Outer Space Treaty, 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, is the primary international agreement governing the exploration and use of outer space.

Planetary protection protocols are designed to prevent the contamination of other planets and moons with Earth life, and to protect Earth from contamination by extraterrestrial life.

NASA is responsible for implementing planetary protection protocols for the United States. These protocols are designed to prevent the contamination of other planets and moons with Earth life, and to protect Earth from contamination by extraterrestrial life.

The ethical principle of non-maleficence in the context of space exploration is the principle of doing no harm to other planets and moons. This principle requires that we take all reasonable steps to avoid contaminating other planets and moons with Earth life, and to protect Earth from contamination by extraterrestrial life.

Viking 1 was the first space mission to implement a planetary protection protocol. The Viking mission was designed to search for life on Mars, and the planetary protection protocol was designed to prevent the contamination of Mars with Earth life.

The Committee on Space Research (COSPAR) is the international organization responsible for coordinating planetary protection efforts. COSPAR is a scientific organization that promotes international cooperation in space research, and it has a standing committee on planetary protection that develops and recommends planetary protection protocols.

Stardust was the first space mission to successfully return samples from another planet to Earth. The Stardust mission was designed to collect samples of cometary dust, and it successfully returned samples from comet Wild 2 to Earth in 2006.

The Planetary Protection Office is the NASA program that is responsible for developing and implementing planetary protection protocols. The Planetary Protection Office is responsible for ensuring that NASA missions do not contaminate other planets and moons with Earth life, and that Earth is protected from contamination by extraterrestrial life.

Viking 1 was the first space mission to successfully land on Mars. The Viking 1 mission was designed to search for life on Mars, and it successfully landed on the surface of Mars in 1976.

The Outer Space Treaty prohibits the placement of nuclear weapons or other weapons of mass destruction in orbit around Earth, on the Moon, or on other celestial bodies. The Outer Space Treaty also prohibits the establishment of military bases, installations, and fortifications on the Moon or other celestial bodies.

Apollo 11 was the first space mission to successfully land on the Moon. The Apollo 11 mission was launched by NASA on July 16, 1969, and it successfully landed on the Moon on July 20, 1969.

The Human Exploration Program is the NASA program that is responsible for developing and implementing human space exploration missions. The Human Exploration Program is responsible for developing the spacecraft, rockets, and other technologies needed for human space exploration missions, and for training astronauts for these missions.

Sputnik 1 was the first space mission to successfully orbit the Earth. Sputnik 1 was launched by the Soviet Union on October 4, 1957, and it successfully orbited the Earth for 98 days.

The Robotic Exploration Program is the NASA program that is responsible for developing and implementing robotic space exploration missions. The Robotic Exploration Program is responsible for developing the spacecraft, rockets, and other technologies needed for robotic space exploration missions, and for selecting and managing these missions.

Venera 7 was the first space mission to successfully land on Venus. Venera 7 was launched by the Soviet Union on August 17, 1970, and it successfully landed on the surface of Venus on December 15, 1970.
