Which of the following statements regarding the current landscape and challenges of space tourism is incorrect?
Show answer & explanation
Correct answer: C
Explanation
Solution: The correct answer is International treaties such as the Outer Space Treaty (1967) clearly define the legal liability and regulatory framework for commercial space tourists in all jurisdictions.
Explanation:
☛ The Outer Space Treaty (1967) and other early United Nations space treaties focus on state-sponsored exploration and classify astronauts as "envoys of mankind".
☛ These historic treaties do not provide clear legal definitions, passenger liability rules, or uniform safety regulations for commercial space tourists.
☛ Suborbital flights, such as those by Blue Origin (New Shepard) and Virgin Galactic (SpaceShipTwo), fly above the boundary of space (or near it) allowing passengers to experience weightlessness for a few minutes without entering Earth's orbit.
☛ Orbital missions, such as those conducted by SpaceX (e.g., Inspiration4), require reaching orbital velocities (about 28,000 km/h or 7.8 km/s), demanding complex heat shields, radiation shielding, and long-duration life-support systems.
☛ Reusability of rockets and spacecraft remains crucial to lowering the cost of spaceflight and ensuring commercial viability.
Extra Exam-Relevant Facts:
☛ Dennis Tito: In 2001, American engineer and businessman Dennis Tito became the world's first commercial space tourist by flying to the International Space Station (ISS) aboard a Russian Soyuz spacecraft.
☛ Kármán Line: The internationally recognized boundary of space is commonly set at an altitude of 100 kilometres (62 miles) above sea level by the Fédération Aéronautique Internationale (FAI).
☛ Inspiration4: Launched in September 2021 by SpaceX, it was the world's first all-civilian human spaceflight mission to orbit Earth.
☛ Rescue Agreement (1968): Mandates that states assist personnel of a spacecraft in distress, but it does not specify protections for private tourists.
