Hmm, I like this. Thinking about it, it sounds somewhat like somebody telling the story later that didn’t expect to survive. Maybe this needs a sequel/prequel.

Space needed before “I shut off”.

You provide enough insight on the scenario to keep it ‘real’ and not so much as to detract from the actual story about the astronaut.

i heard that in space they always carried a wrench so if they started to float away they culd throw the wrench and propel themselves the other way so i tried the same thing xcept an astronaut and a ship. feel free 2 write a sequel/prequel if u want lol my inspiration comes an goes so i might not get back 2 this 4 awile
