A common word for this is methanation. That's one of the two reasons for the selection of methane and oxygen as the fuel and oxidizer. 1. the months-long deep space journeys to and from Mars). Could you write out the chemical equations which are assumed as basis for the overall process? Known as in-situ resource utilization (ISRU), Musk briefly commented on SpaceX’s in-house work on the tech in an October 2017 Reddit AMA (Ask Me Anything), noting that “Design is pretty far along…it’s a key part of the whole system.” His most recent tweet on June 10 reiterated ISRU’s centrality to any successful (read: sustainable) colonization of Mars, and the CEO further confirmed what was already all but guaranteed, describing a chemical reaction known as the Sabatier process. Also a good use of excess heat. Solar power at Mars is going to be less than Earth (about half), but there's less atmosphere to get in the way. To do that in 2 years, assuming nice clear skies, is 3.42 MWh per earth day. 2600 m2, or about a square 50m by 50m. Originally developed by Nobel Prize-winning French chemist Paul Sabatier in the early 1900s, this process uses a catalyst that reacts with carbon dioxide and hydrogen - both byproducts of current life-support systems onboard the space station - to produce … I made a spreadsheet to estimate the power requirements of producing fuel for BFS, using numbers from this PhD thesis which took them from values achieved by NASA. Let's assume 10 hours of solar production per 'day', and a panel able to do 200W and we are looking at .... 1712 panels. Elon Musk also owns SpaceX, so people are naturally going to lump them together in their minds. The SpaceX founder says that CH4 could be synthesised from Martian subsurface water and from atmospheric carbon dioxide (CO2), using a chemical process known as the Sabatier reaction. Follow us for live updates, peeks behind the scenes, and photos from Teslarati’s East and West coast photographers. Scientists at the University of California, Irvine (UC Irvine) have figured out how to produce rocket fuel using only portable materials and resources that can be sourced from Mars. It is likely somewhat optimistic and does not include the energy required to keep the propellant liquefied. At least until SpaceX chooses to jump into the ring with the US nuclear (fissile) material regulation apparatus and develop or launch nuclear reactors, the most reliable power source for interplanetary colonization, that power will have to be supplied by acres upon acres of solar panels optimized to be as light, dense, and efficient as possible. First, a quick primer. Is purification one of the concerns? If they were just 5mm thick, that's over 12.7m3 of cargo - and they need to be set up automatically, preferably at the optimum angle. Starship will use Methane (CH4) and Oxygen (O2) as fuel. The section on Wikipedia is based on a prototype that Robert Zubrin made, intended for a small-scale sample return mission. The beauty of the Sabatier reaction is that it’s nearly a closed loop: the water generated can be split again and pumped back into the reaction to continue generating more oxygen and fuel through CO2 methanation. CO2 + 4H2 = CH4 + 2H2O. and destroying any such evidence. You'll get better rates with different catalysts, but this is a very well-established technology. Using the parameters that are my best guesses, the power needs are 9.1 kWh per kg of propellant produced. This process, known as the Sabatier process, is used on the International Space Station to produce breathable oxygen from water. The BFR spaceship pictured landing on Mars. Less consumable mass required to keep passengers alive and happy directly translates into more payload to the surface of Mars, lowering the overall cost per kilogram delivered and thus the cost per ticket! The Methane (CH4) and water will be collected in separate containers. Big Falcon Rocket (2018 rebiggened edition), Yes, the F stands for something else; no, you're not the first to notice, Interplanetary Transport System (2016 oversized edition) (see MCT), Reaction between hydrogen and carbon dioxide at high temperature and pressure, with nickel as catalyst, yielding methane and water, Application of DC current to separate a solution into its constituents (for example, water to hydrogen and oxygen). Press question mark to learn the rest of the keyboard shortcuts. In the case of SpaceX’s BFR rocket and spaceship, its propellant of choice will be liquid oxygen and methane (known as methalox) partly because of how comparatively easy it is to handle methane and to produce it on Mars, while simultaneously being a significant enabler of efficient long-term crewed spaceflight (i.e. ... New SpaceX Raptor engine beats the … Let's say 2.5 GWh of power. The cryocooler power need is also much higher than would be needed for larger scale production, in Zubrin's system 4.07 kWh are required to liquefy 1 kg of propellant. The SpaceX founder says that CH4 could be synthesised from Martian subsurface water and from atmospheric carbon dioxide (CO2), using a chemical process known as the Sabatier reaction. Hi everyone, here is my rendition of a Sabatier Fuel Plant that could be implemented after SpaceX starts landing on Mars. I expect the meltwater to be full of salts so it would need to be distilled before use. Are there any advances and test plants running anywhere that work better than this? SpaceX Starship: how the Mars base could offer refueling services. After landing on Mars, Sabatier reactors would be used to gradually refuel each Big F. Spaceship. Methane-fueled rocket engine under development by SpaceX, see ITS: Sabatier: Reaction between hydrogen and carbon dioxide at high temperature and pressure, with nickel as catalyst, yielding methane and water: electrolysis: Application of DC current to separate a solution into its constituents (for example, water to hydrogen and oxygen) the power needs are 9.1 kWh per kg of propellant produced. SpaceX has suggested building a propellant plant on Mars that would use this process to produce methane (CH 4) and liquid oxygen (O 2) from sub-surface water ice and atmospheric CO 2. Starship will use Methane (CH4) and Oxygen (O2) as fuel. Hydrogen is combined with CO 2 from the atmosphere, with methane then stored as fuel and the water side product electrolyzed yielding oxygen to be liquefied and stored as oxidizer and hydrogen to be recycled back into the reactor. SpaceX The Sabatier process, mentioned above and used by NASA on the International Space Station, uses a catalyst to react with carbon dioxide and hydrogen. The Sabatier process is not new, being developed a century ago. … Oh, and that power doesn't get to be used for anything else for those two years. I do not seem to fully understand the resulting masses obtained in the spreadsheet i.e. Getting a design optimized for use on Mars is a bit more challenging, but still in the realm of projects that engineering firms will take on with high confidence. do you really think they'll use strip mining to extract the water? Currently its used on ISS. Water can be easily decomposed into hydrogen and oxygen or used for drinking, cooking, and plumbing, among an infinite number of other uses. The energy required to make propellant must be greater than the energy released during launch, so there is a lower bound to how much power can be used to produce a given quantity of propellant.

Future Martians will be able to fuel Starship to return to Earth by extracting carbon dioxide from the Red Planet’s atmosphere and digging subsurface ice-water to synthesize methane through the Sabatier process … schwit1 shared this article from Space.com (which includes a really cool video): The European launch provider Arianespace -- best known as the manufacturer of the heavy-lift Ariane 5 and the future Ariane 6 -- has a plan to make its future rockets more competitive in a tight launch industry.As you might guess from looking at the U.S. company SpaceX's reusable Falcon 9 and Falcon Heavy … But I've seen a NASA paper suggests CO2 can be cryocooled for just 1.23 kWh/kg. Even so, and even getting rid of extra mass/thickness, that's 2000+ solar panels. Copyright © TESLARATI. And there will also be a good deal of power required to mine the water in the first place. The Sabatier reaction has been proposed as a key step in reducing the cost of human mission to Mars (Mars Direct, SpaceX Starship) through in-situ resource utilization. An optimized system of this design massing 50 kg "is projected to produce 1 kg/day of O2:CH4 propellant ... with a methane purity of 98+% while consuming 700 Watts of electrical power." mass ratio of 4 between CH4 and H2. … (SpaceX), A US astronaut completes installation of the ISS’s upgraded Sabatier reactor, which helps to partially close the loop on water consumables. A fully loaded SpaceX BFR spaceship requires more than 1,000 tons of propellant. Of course, the Sabatier process follows the laws of thermodynamics and thus requires a … The Sabatier reaction and water electrolysis are used to convert atmospheric carbon dioxide and water extracted from regolith, or the atmosphere, into propellant. After landing on Mars, Sabatier reactors would be used to gradually refuel each Big F. Spaceship. This is called the Sabatier method and it is already used on the International Space Station, but then to produce water and oxygen. The SpaceX founder says that CH4 could be synthesised from Martian subsurface water and … With any luck, followers of SpaceX may get an update on the company’s BFR plans later this year, likely just before or immediately after the first prototype spaceship is shipped to Texas for acceptance testing and a Grasshopper-style program of suborbital hops. READ MORE: Space calendar 2021: All the SpaceX … Starship fuel could be made by capturing carbon dioxide (CO2) from the Martian atmosphere and digging water ice to synthesize methane through the Sabatier process/electrolysis. This is driven primarily because this process can exploit the extremely high availability of carbon dioxide in the Martian atmosphere to create both the methane fuel and water, … For Mars, methane propellant can be manufactured via the Sabatier process. The Sabatier reaction is a process that produces water (hydrogen and oxygen) and methane through a reaction of hydrogen with carbon dioxide. On the next step, through a chemical process known as the Sabatier process, Carbon dioxide (CO2) and Hydrogen (H2) would create Methane (CH4). Cookies help us deliver our Services. In 2018 SpaceX founder Elon Musk shared SpaceX is working on the development of a high efficiency carbon capture system to capture CO2 to utilize in fuel production. Do you know if SpaceX or anyone else is actually prototyping bigger Sabatier machinery? Ultimately the power needs are so high because rocket propellant needs to store an incredible amount of energy in order to produce the kinetic energy required to launch the BFS. Optimally, BFS’ own internal solar array would (and likely will, at least at first) double as a source of power both in space and on the surface of Mars, neatly removing the need to waste precious cargo space on duplicate hardware. The zinc acts as a catalyst for carbon dioxide, which reacts with … CO2 + 4H2 = CH4 + 2H2O. Thanks to LEGO City Space for helping us envision life on Mars! If anything, the dust storm currently threatening the livelihood of Mars rover Opportunity should serve as evidence that solar power on Mars is at best a relatively cheap and simple stopgap for better power sources, especially for any long-term human presence on the Red Planet. So 240,000 kg of CH4 means 2184000 kWh at least. By using our Services or clicking I agree, you agree to our use of cookies. This subreddit is not an official outlet for SpaceX information. The scientists developed a one-step process that requires only zinc, a mineral found on the red planet, and a small easy-to-carry device to catalyze carbon dioxide and produce methane-based fuel. All rights reserved. Akin to a more advanced version of what is already successfully utilized aboard the International Space Station, efficient Sabatier reactors can also be used to partially recycle wastewater and carbon dioxide (produced by humans breathing) to recover a significant fraction of pure water and methane. You could pull reactor vessels out of a major refinery plant, clean them, feed in CO2 and H2 and get methane out the other end at reasonable rates. (credit: SpaceX) A propellant processing plant only using the Sabatier process makes the same amount of methane as oxygen. SpaceX CEO Elon Musk took to Twitter to reaffirm SpaceX’s commitment to developing their own technology for refueling BFR beyond Earth, noting that the high-efficiency hardware would be “critical for propellant production at Mars Base Alpha.”.
