They supply power to the spacecraft during missions.
Because they have enough energy or strength to make a spacecraft work
so they can go out on mars and other planets
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
because they are used to provide water and electricity for the spaceship... so very useful....
because it is to do with other planets but mostly mars and galexy if we had the tehcnical difficultys in the balance of time, timeloards from Doctor Who would come back to life if we belived.
they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells Because fuel cells do actually fart it's well documented. And they do a poo when they get tired! < SOOO TRUE!!
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
Without fuel, the spacecraft cannot launch.
Yes. Mass producing cars is not the problem. The fuel for fuel cells is too expensive, so far.
Microscopes are useful so you can see cells.
Saturn is a gas planet, so it has no surface
Fractional distillation is used to obtain diesel fuel, kerosene, gasoline and many others useful products.
A cytotechnician can be useful. Their job is to separate normal cells from abnormal cells. After they have done that Pathologists, doctors who specialize in the study of abnormal cell structure, then look at the abnormal cells.
