What will happen to the astronaut who is floating outside the spacecraft holding on to the rope tied to the mother probe and if the rope breaks?

His oxygen pack contains breathing air for seven and a half hours

His space suit will have liters of water to quench his thirst

The jet pack will carry 5 pounds of fuel to fly back to his parent spacecraft

He would have died and drifted off into space unless someone else had already rescued him and brought him back to the spacecraft. Sometimes it enters the Earth’s atmosphere and ends up burning up like a meteor!
