Spacewalks are like giving astronauts a superhero cape so they can fix the ISS robotic arm when it needs help.
Imagine you have a toy robot that helps you build your Lego city, but one day, it stops working because its arm got stuck or broken. You need to go up close and personal with the robot to make it better again. That’s what astronauts do during a spacewalk, they go outside the ISS like a brave explorer to fix the robotic arm, which is like the robot's helper.
Why Can't Robots Fix Themselves?
Sometimes, even the smartest robots need a little help from humans. The robotic arm on the ISS does lots of important jobs, like moving equipment or helping astronauts get to their spots. But if it breaks down, it can’t fix itself, just like how your toy robot might need you to push its buttons again.
Astronauts are like super repair technicians who go out into space with tools and a lot of patience. They work outside the ISS in spacewalks, fixing parts that the robotic arm needs so it can keep helping everyone on board, just like how you help your robot get back to action!
Examples
- An astronaut needs to fix a broken part on the robotic arm outside the ISS, like replacing a faulty gripper.
- Sometimes robots get stuck or need extra tools that only humans can provide during spacewalks.
