The Outer Space Treaty, formally 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 treaty governing the activities of astronauts in outer space.

Under the Outer Space Treaty, astronauts are considered to be representatives of their respective countries, and they are subject to the jurisdiction and control of their own countries.

Under the Outer Space Treaty, astronauts have a number of responsibilities, including conducting their activities in a peaceful manner, avoiding causing harm to the environment of outer space, and cooperating with other astronauts from different countries.

The Outer Space Treaty does not explicitly grant astronauts any specific rights. However, astronauts are generally considered to be entitled to the same rights and protections as other individuals under international law.

In the event of an emergency, astronauts are generally considered to be subject to the jurisdiction of their own countries. However, there may be exceptions to this rule, such as when an astronaut lands in a country other than their own.

The Moon Agreement, formally known as the Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, is an international treaty that governs the activities of astronauts on the Moon and other celestial bodies.

The Moon Agreement contains a number of provisions, including a prohibition on the use of nuclear weapons on the Moon, a system for the allocation of resources on the Moon, and the creation of an international organization to oversee lunar activities.

As of 2023, no country has signed and ratified the Moon Agreement. The United States, Russia, and China are among the countries that have expressed reservations about the treaty.

The Rescue Agreement, formally known as the Agreement on the Rescue of Astronauts, the Return of Astronauts, and the Return of Objects Launched into Outer Space, is an international treaty that governs the rescue of astronauts in distress.

The Rescue Agreement contains a number of provisions, including a requirement for states to provide assistance to astronauts in distress, a system for the coordination of rescue operations, and the creation of an international fund to cover the costs of rescue operations.

As of 2023, the Rescue Agreement has been signed and ratified by the United States, Russia, China, and a number of other countries.

The Liability Convention, formally known as the Convention on International Liability for Damage Caused by Space Objects, is an international treaty that governs the liability of states for damage caused by space objects.

The Liability Convention contains a number of provisions, including a system for determining liability for damage caused by space objects, limits on the amount of liability that states can be held responsible for, and the creation of a fund to compensate victims of damage caused by space objects.

As of 2023, the Liability Convention has been signed and ratified by the United States, Russia, China, and a number of other countries.

There are a number of challenges to the legal status of astronauts, including the lack of a comprehensive international treaty governing the activities of astronauts, the different interpretations of existing international treaties by different countries, and the emergence of private space companies.
