I'm confident that we'll detect signs of life on exoplanets (planets around other stars) by observing the atmospheres of the planets that we're detecting now — especially those similar to Earth in mass and orbit — and finding oxygen and other chemical signatures there.
Once there it will produce propellant on Mars itself, either by distilling carbon dioxide from the atmosphere and mixing it with hydrogen brought from Earth to generate methane and oxygen or by electrolyzing water from the permafrost to make liquid hydrogen and oxygen.
By calculating the number of these elements relative to oxygen, the researchers were able to predict how much oxygen should be in the atmosphere of the white dwarf — but they found significantly more oxygen than if there were only rocks.
