An astronaut with a broken tether can return to the spacecraft by using the principle of conservation of momentum. By throwing an object away from them in the opposite direction of the spacecraft, the astronaut will experience an equal and opposite force that will propel them back towards the spacecraft. This action will help the astronaut overcome the lack of propulsion caused by the broken tether and allow them to return to safety using physics principles. **

If an astronaut's tether breaks while they are on a spacewalk, they can use physics to get back to the spaceship by using the conservation of momentum. By throwing an object in the opposite direction of the spaceship, the astronaut will start moving in the opposite direction due to the conservation of momentum. This will allow them to propel themselves back towards the spaceship. Additionally, they can use their body movements and thruster adjustments to change their trajectory and speed, ultimately allowing them to reach the spaceship. **
