Question

Quizplus · Accepted Answer

An interstellar ramjet is a spacecraft that collects its fuel during its passage through space. It uses a scoop at the front of the spacecraft to collect interstellar hydrogen and then compresses and heats it to create propulsion. The other options do not collect fuel during their passage. An interstellar ark is a hypothetical concept for transporting life or civilizations to other star systems. A matter-antimatter rocket uses a fuel made of matter and antimatter that is carried on board the spacecraft. A solar sail is propelled by the momentum of photons from the sun but does not collect its fuel during its journey.
