Test your knowledge on the orbiting laboratory, a symbol of international collaboration and continuous human presence in space.
The first component of the International Space Station (ISS), the Zarya module, launched on November 20, 1998, from the Baikonur Cosmodrome. This marked the beginning of an ambitious undertaking to construct a permanent human outpost in low Earth orbit. Two years later, on November 2, 2000, the ISS welcomed its first long-duration crew, establishing an uninterrupted human presence in space that continues to this day. The station has since become the largest human-made structure in space, providing a unique environment for scientific advancement.
The ISS is a collaborative effort involving five space agencies representing 15 countries, including the United States, Russia, Europe, Japan, and Canada. Orbiting approximately 400 kilometers (250 miles) above Earth at a speed of about 28,000 kilometers per hour (17,500 mph), it completes an orbit roughly every 90 minutes. This orbiting laboratory serves as a platform for extensive microgravity research across various scientific disciplines, developing technologies for future space exploration and yielding benefits for life on Earth.
