Answers below are taken from the article’s stored facts, so they match what the student read.

1. How high is Scientific research on the International Space Station?Average of 250 miles (400 km) above Earth
2. What is the orbital velocity?Approximately 17,100 miles per hour (7.66 km/s)
3. What is the first module launch?November 20, 1998 (Zarya)
4. What is the International Space Station (ISS)?The ISS is a big space laboratory that orbits Earth about 400 kilometers up, where there is almost no air and very little gravity. It lets scientists do experiments that would be hard or impossible on Earth.
5. How fast does the ISS travel and how many sunrises does it see each day?The ISS moves at about 7.66 kilometers per second, which is about 17,100 miles per hour. It circles the Earth roughly 15.5 times each day, so it sees about 16 sunrises and sunsets every day.

Low Earth Orbit (LEO): The region of space extending from the Earth's surface up to approximately 2,000 kilometers altitude.
Extravehicular Activity (EVA): Any activity performed by an astronaut outside a spacecraft, commonly known as a spacewalk.
Physiological Adaptation: The changes that occur in the human body in response to the space environment, such as bone loss or muscle atrophy.
