3. Diaphragm Pumps These are another type of positive displacement pump, where a flexible diaphragm compresses the slurry in a chamber, creating a flow. Diaphragm pumps are excellent for applications requiring strict fluid containment, such as chemical processing, since they minimize the risk of leaks.
The low-pressure environment presents a range of challenges for human exploration. Spacecraft designs must take into account the effects of low pressure during landing, ascent, and surface operations. Habitats for astronauts will need to be airtight to maintain a safe atmospheric pressure for human survival.
