International Space Station (ISS) – Study Notes
Introduction
The International Space Station (ISS) is a modular space station in low Earth orbit (LEO), representing a collaborative project among multiple countries. It serves as a microgravity and space environment research laboratory, where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is a symbol of international cooperation and technological achievement, continuously inhabited since November 2000.
Main Concepts
1. Structure and Design
- Modular Architecture: The ISS is composed of pressurized modules, external trusses, solar arrays, and other components. Major modules include Zarya (Russian), Unity (US), Columbus (European), Kibo (Japanese), and others.
- Dimensions: The station measures approximately 109 meters end-to-end, with a mass of over 420,000 kg.
- Orbit: It orbits Earth at an altitude of ~400 km, traveling at 7.66 km/s (about 28,000 km/h), completing 16 orbits per day.
2. International Collaboration
- Partners: NASA (USA), Roscosmos (Russia), ESA (Europe), JAXA (Japan), CSA (Canada).
- Governance: The ISS operates under intergovernmental agreements, with each partner responsible for specific modules and research.
- Crew: Typically, 7 astronauts from various countries reside on the ISS, conducting experiments and maintaining station operations.
3. Scientific Research
Microgravity Experiments
- Biology: Studies on cellular growth, gene expression, and disease modeling (e.g., muscle atrophy, bone loss).
- Materials Science: Investigation of alloys, polymers, and crystal growth without gravity-induced defects.
- Physics: Research on fluid dynamics, combustion, and fundamental particle interactions.
Earth and Space Observation
- Remote Sensing: Monitoring climate change, natural disasters, and atmospheric phenomena.
