This flow chart reveals the procedure humans on Mars will use as they synthesize the products they need from the raw materials on the world. The devices they utilize will be transferred from Earth (at first), however will require trustworthy power. (Credit: Aaron Berliner and Davian Ho, UC Berkeley).
Mars Needs Power!
Standard knowledge states that nuclear power units comparable to what powers other spacecraft are the best option. Just one nuclear power plant supplying about a kilowatt of power would be about 9.5 tons. Like solar power?
Thats the concern a set of college students at the University of California at Berkeley wished to respond to. They did a research project looking at future power sources for Martian colonists. Aaron Berliner concentrates on nuclear engineering while Anthony Abel is interested in advances in solar batteries for solar power. Together, they evaluated the power needs for a six-person objective staying on Mars for 480 days. In particular, they looked at websites on Mars where solar power may make a great deal of sense. And, what they found appears to puzzle the traditional wisdom.

At some point in the next number of years, humans will head to Mars for long-lasting missions of more than 400 days. Such lengthy stays indicate constructing Martian cities, complete with safe environments, labs, and other facilities. Future Martians will need to do a lot to endure. Theyll develop their cities, make their own food, distill water, produce fuel, manufacture medications, and develop other products. To do that, theyll utilize making facilities that they bring along. That all needs power. Great deals of it. As we all know, Mars is visibly lacking in obvious ways to make electrical energy. What will our brave explorers do to create power for their brand-new lives on the Red Planet?

An artists concept of a future biomanufacturing lab on Mars, powered by photovoltaic (solar power) innovation. Standard wisdom says that nuclear power systems comparable to what powers other spacecraft are the finest choice. Just one nuclear power plant providing about a kilowatt of power would be about 9.5 loads. Second, solar power cells weigh less than nuclear power plants. As newer, lighter cells come online, solar power might be the main source of power for future Martian colonies.

Many are also in the exact same areas and have used solar power for some aspects of their explorations. Credit: Anthony Abel and Aaron Berliner, UC Berkeley).
If our future Martians settle in the mid-latitudes, particularly around the worlds equatorial areas, solar power stations might defeat nuclear. Second, solar power cells weigh less than nuclear power plants. To get the exact same power as a nuclear plant, new-generation solar tech would just take up about 8.3 heaps of cargo.
Mars and Next-Gen Solar Power.
What kind of power cells are we speaking about here? Berliner and Abel looked at systems that use photovoltaic power with electrolysis. That is, they utilize electrical power to divide water into hydrogen and oxygen. The students likewise determined that a few of the energy produced during the daytime would be utilized to produce hydrogen gas for use in fuel cells. This is roughly similar to the method some companies and houses here in the world use solar energy to keep energy in Powerwalls and batteries for night-time usage.
The cool news? All this solar energy goodness is possible with existing photovoltaic technologies. And, naturally, the technology is always enhancing, so by the time a Mars mission is ready to lift off, whole new variations of todays solar batteries will be prepared to utilize.
” The silicon panels that you have on your roof, with steel building, glass support, and so on, simply will not complete with the brand-new and enhanced nuclear,” stated Abel in a press release from UC Berkeley, “But these more recent lightweight, versatile panels all of an abrupt really, actually change that conversation.”.
Advantage: Solar Power.
As more recent, lighter cells come online, solar power might be the primary source of power for future Martian colonies. Thats not to state nuclear power wont be there, too. And, in the near future, with the requirement to keep expenses down, solar power might well be the way to go.
For more details, the paper that Abel and Berliner wrote is entitled “Photovoltaics-Driver Power Production Can Support Human Exploration on Mars”, and published in Frontiers in Astronomy and Space Sciences. Their work was moneyed by NASA in addition to the National Science Foundation.
