Can Mars floor rover/research breathe made from plastics?
Plastics are noble, nevertheless they do not have the temperature meander or power of metals. You necessity a cloth that’s gentle weight, capable of contest the forces of a launch and re-entry, and capable of stay stout at vicious temperature extremes.
Many plastics grow to be brittle when artic.

Not many plastics stay ductile at that temperature, acceptation they crack simply. If you take a look at the frequent plastics utilized in 3d printing and their lowest ductile temperature you’ve:
- ABS: -40°C
- PLA: -30°C
- Nylon: -40°C
These are noble supplies as a result of they fuse at a comparatively low temperature, however their different properties aren’t model.
Some plastics have a mighty scowl temperature meander, acrylic can stay as little as -150°C, it is not that stout although so it will aim up heavier than steel.
