Final answer:
The three missions of the International Space Station (ISS) are scientific research, international cooperation, and human space exploration.
Step-by-step explanation:
The three missions of the International Space Station (ISS) are:
- Scientific Research: The ISS serves as a unique platform for conducting various scientific experiments and research in microgravity. Scientists from around the world use the ISS to study the effects of long-duration space travel on the human body, conduct physics experiments, and gather data on Earth's atmosphere and climate.
- International Cooperation: The ISS is a collaborative project between multiple space agencies, including NASA, Roscosmos, ESA, JAXA, and CSA. The international partnership fosters scientific and technological collaboration, promotes peaceful cooperation in space exploration, and strengthens diplomatic relations between countries.
- Human Space Exploration: The ISS serves as a stepping stone for future human space exploration missions. Astronauts on the ISS gain valuable experience and knowledge that will contribute to the development of technologies and strategies for long-duration space travel, such as missions to Mars.
