1. Using Handrails and Foot Restraints:
* Inside the Space Station: They use handrails and foot restraints strategically placed throughout the station to help them maneuver.
* Inside the Space Shuttle: Similar to the space station, handholds and foot restraints were provided for movement.
2. Using Jetpacks (MMUs):
* Spacewalks: During spacewalks, astronauts used Manned Maneuvering Units (MMUs), also known as "jetpacks". These were backpack-like devices with small jets that allowed astronauts to move around freely in space. However, they were bulky and complex, and are no longer used.
3. Using Tethers:
* Spacewalks: Astronauts use tethers to stay connected to the spacecraft during spacewalks. They can use the tether to pull themselves along and to prevent themselves from drifting away.
4. Using the Space Station's Arms:
* Moving Supplies: The International Space Station has robotic arms that can be used to move large objects and supplies around the station's exterior.
5. Using Momentum:
* Floating: In microgravity, astronauts can simply push off of something to move in a specific direction. This is how they move around inside the space station.
6. Using "Zero-G" Thrusters:
* Docking: Some spacecraft, such as the Crew Dragon, use small thrusters to move and align during docking maneuvers.
7. Using a "Zero-G" Chair:
* Training: During training, astronauts use a specialized chair that simulates microgravity. This allows them to practice movement and tasks they will need to perform in space.
It's important to note that moving in space is not as easy as it looks. It requires careful planning, precise execution, and constant awareness of one's surroundings. Astronauts need to be trained extensively to move safely and efficiently in space.
