Question

In space, astronauts don’t have gravity to keep them in place. That makes doing even simple tasks difficult. Gene Cernan was the first astronaut who worked on a task outside a spaceship. He said of the experience, “Every time I’d push or turn a valve, it would turn my entire body at zero gravity. I had nothing to hold on to.” As he worked, Gene Cernan’s heart rate and temperature went so high that his fellow astronauts worried that he wouldn’t survive.

Think about routine tasks that astronauts might need to do inside and outside a spaceship. Choose several tasks, and describe the features the ship and spacesuits should have to account for zero gravity as the astronaut completes the task. Use Newton’s laws of motion in your analysis.

Answer 1

Think about routine tasks that astronauts might need to do inside and outside a spaceship. Routine things like using the bathroom, brushing your teeth etc. probably isn't as easy for astronauts in space newton laws of motion states "if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force." for astronauts you are in constant state of unbalancing you have no control of. simple things like drinking water that you have done countless times is now different. showering in space also isn't the same as you would do normally astronauts have to use liquid soap and water from pouches onto their skin they use rinse less soap with a little water to clean their hair.
