# How many hours/week on the ISS is spent on science vs maintenance?

This was asked in 2016 : Does ISS crew exercise time count toward their X hour work week? The answer as of 2016 was 40 hours / week for a crew of 6. But as noted there, when the crew size increases to 7 there would be a significant increase in science output. With crew dragon carrying an extra crew number, is there an updated figure for this number?

• From another answer: "The staff on board [get a single person-day of science work completed] when there are 6 astronauts, between exercise, sleeping, and maintenance" (reformatted sentence for clarity). This seems weird/extreme. Assuming 8 hours of sleep, 6 hours for relaxation/personal hygiene/etc., so that you have (24-8-6=)10 hours of work per day: at 6 persons = 60 working hours per day, you would get only 8 hours (13%) for science, and the rest is all chores/maintenance. I'm a bit doubtful but I know nothing.
