Pressure-Fed <strong>Systems</strong><br />

Note<br />

- 18-<br />

Note that due <strong>to</strong> long space flight mission duration, only pressure-fed systems are used<br />

because of their inherent simplicity compared with pump-fed systems, which are used<br />

commonly for launch propulsion.<br />

In addition, for long space flight missions, only s<strong>to</strong>rable propellants, which can be s<strong>to</strong>red<br />

for long periods in sealed tanks, are used.
