Most previous rocket engines have relied on using fuels like kerosene in place of methane. But the main benefit of using methane is that it has a higher performance than other fuels, meaning the rocket can be smaller. Its lower cost, too, means the total cost of launching can be brought down.

Since CO 2 ; is plentiful in the Martian atmosphere, methane (CH 4) and oxygen (O 2 ) can be extracted and used as rocket fuel and its oxidizer. We are literally making rocket propellant out of thin air! Methane is also an easier fuel to store for a longer duration than the standard fuel of liquid hydrogen used in most rockets.

SpaceX have put methane on the map as a rocket fuel, but they weren't the first to consider its use. The first experiments in building a rocket engine that uses methane date back to 2007. Now methane isn't exactly an exotic fuel. It's widely in use in other applications and its combustion process is well understood.

Uranium cannot be used as ‘fuel’ for a rocket per sey, but can be used as a propulsion component as was done with the NERVA program. ( NERVA - Wikipedia ) It does this via having essentially a stripped down reactor that heats up hydrogen by running it by the hot reactor and ejects it out of the fairly conventional rocket nozzle.

Methane-based rocket fuel can be made on MARS in a one-step process that uses zinc and a small portable device, physicist claims. Experts have devices a plan for astronauts get enough fuel to return to Earth from Mars – by making methane-based fuel on the surface of the Red Planet.
Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite.
However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change. Although methane’s lifespan in the atmosphere is relatively short compared to those of other greenhouse gases, it is more efficient at trapping heat than are those other gases.

Reduction of methane emissions through feed additives, such as fats and oils, can reduce methane production by about 18% and offer energy and protein to the animal. For a 600 cow dairy herd (producing 100kg of methane per head per year) methane emissions could be reduced by 372 tonnes of carbon dioxide equivalent per year.
Methane is nontoxic on its own but can become lethal when it combines with another gas. Methane causes asphyxiation by displacing oxygen. It may produce symptoms of dizziness and headache , but these often go unnoticed until the brain signals the body to gasp for air. This happens too late, and the individual collapses.

A gas stove is a stove that is fuelled by combustible gas such as syngas, natural gas, propane, butane, liquefied petroleum gas or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836.
