Hi,
We have a hypothetical situation. I am located in the spacecraft in space. And I need tritium and deuterium as fuel for a fusion reactor.

Is this possible? And if so how?

Thank

To get enough deuterium and tritium for practical reactor applications, you would need to get some shipped to you or carry some onboard. You can't rely on the thin vacuumous gas in space (which is something on the order of a few molecules per cubic meter). Well, probably not anyway. Buzzard's Ramjet can theoretically obtain enough gas for fusion if it is travelling fast enough. I don't know if such a technology would rely on proton-proton fusion (light hydrogen fusion) or if deuterium-tritium fusion is also practical with it. Seeing how much more abundant light hydrogen is than the other isotopes, a Buzzard's Ramjet would probably need a reactor capable of using that as a fuel.
