A spacewalk, or extravehicular activity (EVA), is an activity where astronauts leave the confines of their spacecraft to perform tasks in the vacuum of space. These tasks can include repairs, maintenance, or scientific experiments, and require specialized suits to protect astronauts from the harsh environment of space.
The Tiangong Space Station is China's modular space station that is being constructed in low Earth orbit. It is designed to support long-term human operations in space and facilitate scientific research and international collaboration in various fields.
