How can a astronaut use jet pack if it runs out of fuel?

If an astronaut's jet pack runs out of fuel, they would be unable to use it for propulsion. However, they could rely on their tether to the spacecraft or use other safety measures, such as handrails or footholds on the space station, to navigate. Additionally, astronauts are trained in emergency procedures and can use their suits' maneuvering capabilities for limited movement. In extreme cases, communication with mission control would be critical for guidance and support.
