I checked now astros.json and see that it doesn't count Chinese taikonauts as human beings being in space right now. :-(
According to https://en.wikipedia.org/wiki/Tiangong_space_station#Crewed_missions
from 2024-04-25 we have 3 more humans in near Earth space.
So, the correct NUMBER_OF_PEOPLE_IN_SPACE should be 10 for today.
Can you please take Chinese into account too?
I would like to have a precise data source for my pet project.
