Just released today is a new video which delineates SpaceX's New Rockets and Rocket Fuel and why it is so important moving forward into Space...especially to Our Planetary neighbor, Mars, ...
Per Seeker, the creator of this video, "RP-1 had some drawbacks that are leading SpaceX scientists to look at a different propellant, which could be used specifically for Mars exploration. Enter the SpaceX Raptor engine and it’s next generation propellant.
This engine uses a combination of liquid methane and liquid oxygen to create, in my opinion, the perfect mixture for a reusable vehicle on Mars. Not only is this an efficient fuel, but we can easily create it using resources found on the Red Planet. Which is great, because one of SpaceX’s main goals is to create a system that can take humans to Mars and back.
Both methane and CO2 could be extracted from the atmosphere using solar power, and water could be mined near the surface of Mars using wells. And when compared to RP-1, methane has a higher Specific Impulse, a cooler combustion temperature, and prevents coking, or the buildup of deposits in the engine."
""After a century of rocket fuel research that has looked at everything from RP-1 to hydrogen to paraffin, the industry is turning to a surprising new source – methane natural gas. One of the most abundant chemicals on our planet, methane is finally enjoying the spotlight."
"The Raptor engine uses liquid oxygen and methane, unlike the Merlin engine fueled by rocket propellant that powers the Falcon 9. That, combined with the Starship's fully-reusable design, means humans can travel to Mars, harvest the planet's resources, and use that to fuel the return trip."
I hope that you all enjoy this SPACE science video,
Kerry
