The Outer Space Treaty, adopted in 1967, is the primary international treaty governing space law. It establishes principles for the peaceful exploration and use of outer space, including the prohibition of weapons of mass destruction in orbit or on celestial bodies.

NASA is the U.S. government agency responsible for civilian space exploration and research. It was established in 1958 and has played a leading role in space exploration, including the Apollo moon landings and the development of the Space Shuttle.

The Hubble Space Telescope, launched in 1990, is a joint project of NASA and the European Space Agency. It has revolutionized our understanding of the universe, providing stunning images and valuable data on distant galaxies, exoplanets, and other celestial objects.

Neil Armstrong became the first human to walk on the moon on July 20, 1969, during the Apollo 11 mission. His historic words, 'That's one small step for a man, one giant leap for mankind,' marked a significant milestone in space exploration.

The Soviet Union launched Sputnik 1, the first artificial satellite, into orbit around Earth on October 4, 1957. This event marked the beginning of the Space Age and sparked the space race between the Soviet Union and the United States.

The International Space Station (ISS) is a modular space station in low Earth orbit. It is a joint project of five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).

Viking 1 was the first space probe to successfully land on Mars and transmit images and data back to Earth. It landed on July 20, 1976, and conducted a series of experiments and observations, providing valuable insights into the Martian environment.

The James Webb Space Telescope (JWST) is a next-generation space telescope designed to study the early universe and the formation of the first galaxies. It is a joint project of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).

New Horizons was the first space mission to successfully send a spacecraft to Pluto and its moon, Charon. It flew by Pluto in July 2015, providing stunning images and valuable data on the dwarf planet and its surroundings.

The Parker Solar Probe is a space probe sent to study the Sun and its corona. It is the first spacecraft to fly through the Sun's corona, providing unprecedented insights into solar activity and the behavior of the Sun's atmosphere.

Hayabusa2 was the first space mission to successfully land a spacecraft on an asteroid (Ryugu) and collect samples for return to Earth. It returned to Earth in December 2020, bringing back valuable samples that provide insights into the origin and evolution of asteroids.

The Nancy Grace Roman Space Telescope (Roman) is a next-generation space telescope designed to study the formation and evolution of galaxies and the large-scale structure of the universe. It is a joint project of NASA and the European Space Agency (ESA).

Rosetta was a space mission that successfully landed a spacecraft (Philae) on a comet (67P/Churyumov-Gerasimenko) and studied its composition and structure. It provided valuable insights into the nature of comets and the early solar system.

Voyager 1 is a space probe that was sent to study the outer planets of our solar system, including Jupiter, Saturn, Uranus, and Neptune. It is the farthest spacecraft from Earth and has provided valuable insights into the outer planets and their moons.

Mariner 10 was the first space mission to successfully send a spacecraft to Mercury and study its surface and composition. It flew by Mercury three times in 1974 and 1975, providing valuable data and images of the planet.
