Frequently Asked Questions About Human Spaceflight
How was the ISS built?
The International Space Station (ISS) was constructed over 13 years through the collaboration of multiple countries, including the United States, Russia, Japan, and European nations. Thousands of engineers on Earth built different modules, which were then launched into space using Russia’s Proton rockets and the United States’ space shuttles. The assembly of the ISS in space required precise coordination and numerous spacewalks by astronauts to connect the modules and integrate the systems (Kennedy Space Center Visitor Complex) (NASA).
Who is currently on the ISS?
As of the latest updates, six astronauts are aboard the ISS. These astronauts come from various space agencies around the world, including NASA, Roscosmos, and JAXA. The crew members live and work on the station, conducting scientific experiments and maintaining the station’s systems. For the most up-to-date information on the current crew, you can visit NASA’s ISS webpage (Kennedy Space Center Visitor Complex) (NASA).
How long do astronauts stay on the ISS?
Astronauts typically stay on the ISS for about six months, although mission durations can vary. This period allows them to conduct extensive scientific research and adapt to living in microgravity. The record for the longest single spaceflight is held by astronaut Scott Kelly, who spent 340 days on the ISS. For cumulative time in space, astronaut Peggy Whitson holds the record with 665 days (Kennedy Space Center Visitor Complex) (Spot The Station).
