At what altitude do astronauts usually travel?
Understand the Problem
The question is asking about the typical altitude in kilometers that astronauts travel while in space. This question seeks factual information regarding space travel, particularly the altitudes commonly associated with orbiting spacecraft. Astronauts typically travel at altitudes that are defined as low Earth orbit (LEO) and this is usually around 160 to 2,000 kilometers above the Earth's surface.
Answer
About 227 nautical miles (420 km or 250 miles).
Astronauts usually travel at an altitude of about 227 nautical miles (420 kilometers or approximately 250 miles), particularly when aboard the International Space Station.
Answer for screen readers
Astronauts usually travel at an altitude of about 227 nautical miles (420 kilometers or approximately 250 miles), particularly when aboard the International Space Station.
More Information
The International Space Station (ISS) orbits Earth at an altitude that allows it to complete an orbit approximately every 90 minutes. This altitude is chosen to balance gravitational pull and the station's velocity.
Tips
A common mistake is assuming all space missions travel to this altitude. Altitude varies greatly depending on the mission type and destination.
