This greatly increases the difficulty of construction, at the very least, the astronauts' work efficiency is greatly reduced.
Although Mars is very far from Earth, at least there is gravity and a surface there, building things is not as troublesome as in space.
However, constructing things in space isn't without its conveniences, as the current display screen can aptly demonstrate.
At the center of the screen, there is an astronaut pushing a component much larger than himself to the designated location.
Then several astronauts come to take over, and after correcting and adjusting, they splice this component with other things.
This is the benefit of no gravity and friction; astronauts can easily push heavy objects, and they don't have to waste much effort unlike on Earth or Mars, where this astronaut definitely wouldn't be able to push that component.
It is only in such an environment of space that the astronaut can move such heavy things.
