The dream of living on another planet has intrigued scientists, engineers, and explorers for a long time. Now, the dream is moving closer to becoming a reality with researchers at the University of Central Florida<\/a> (UCF) and beyond exploring how human beings could one day build thriving communities away from the planet. From creating breathable air on Mars to finding stable energy reserves in Venusian skies, all of these missions belong to a larger mission ensuring the survival of our species\u2014and extending science\u2019s boundaries.<\/p>\n

Redesigning Mars into a Habitable World<\/p>\n

UCF Planetary Scientist and Astrobiologist Ramses Ramirez is leading the research into how to heat and render Mars liveable again. His focus is on terraforming\u2014a modification of the planet\u2019s environment to make it more Earth-like. With Martian nanoparticles, Ramirez believes that it may be feasible to heat the planet\u2019s surface so that it will be capable of supporting liquid water and plant life. \u201cUltimately, I\u2019m interested in finding life on other planets,\u201d Ramirez says. \u201cAnd if it\u2019s not there, then we should become that life on that planet.\u201d.<\/p>\n

His study of Mars\u2019 ancient climate indicates it was once more Earth-like, with valleys and rivers. These are indicators the planet had an atmosphere dense enough to harbor liquid water in the past. The next question is whether any of those resources still exist\u2014and, if not, how to locate alternatives. \u201cDoes Mars still have enough of those resources that it once did?\u201d Ramirez asks.<\/p>\n

\u201cAnd if they do not exist, then how are we going to create the gaps so that it can be as good as before?<\/p>\n

Terraforming Mars<\/p>\n

Living on Mars means overcoming extreme cold. The average surface temperature is about minus 80 degrees Fahrenheit\u2014far too low for human survival or plant growth. Ramirez\u2019s idea would employ Martian dirt<\/a> to grow microscopic cylindrical nanorods that are smaller than specks of glitter. Discharged into the atmosphere, they would trap solar energy near the surface and create a greenhouse effect.<\/p>\n

According to his research, this method could raise temperatures to around 30 degrees Fahrenheit\u2014enough to start melting ice and supporting simple plant life. The nanorods are 5,000 times more efficient than earlier methods, offering an inexpensive, locally available solution that doesn\u2019t require shipping enormous quantities of material from Earth.<\/p>\n

Ramirez claims that this technique would apply to other planets with different materials, for example, water vapor or carbon dioxide, depending on the atmospheric composition.<\/p>\n

\u201cIt can sustain at least Earth-like life, or at least warm enough conditions with high enough pressures and low enough toxicity to survive,\u201d he describes.<\/p>\n

Finding Food in Martian Soil<\/p>\n

While heating the planet is one thing, keeping a colony alive takes sustenance. Researchers have been trying to grow food in Martian soil analogs for decades. One such technology that has developed realistic Mars soil simulants to research plant development is Space Resource Technologies, which originated as an outgrowth of the Exolith Lab at UCF.<\/p>\n

The Viking, Curiosity, and Perseverance missions<\/a> all discovered organic molecules\u2014the building blocks of life\u2014on Mars. That discovery makes scientists think that at some point in the planet\u2019s past, it had vegetation or microorganisms. \u201cThose conditions could have led to life on early Mars,\u201d Ramirez says. \u201cThat life would then die and hopefully be fossilized.\u201d No such fossils have been found, but the evidence suggests Mars once had many of the compounds necessary for life.<\/p>\n

Powering Life Beyond Earth<\/p>\n

There needs to be constant power sustaining life on Mars, or anywhere for that matter. Solar power has sustained rovers like Spirit and Opportunity, but dust storms and long nights can make sunlight inconsistent. That is why NASA is researching nuclear fission<\/a> devices that would provide 40 kilowatts of continuous power\u2014enough to power about 30 homes\u2014for as long as a decade. These small, lightweight reactors would drive habitats through even the blackest nights.<\/p>\n

Because Mars has a 24-hour, 37-minute day, just like the day on Earth, solar energy is also a possibility there. \u201cI don\u2019t see power being a major problem on Mars,\u201d Ramirez says. Venus and other planets are tougher, though. With slow-spinning rates and dense atmospheres, they need more creative solutions to energy.<\/p>\n

Scientists have proposed solar planes for Venus floating in its upper atmosphere, where it is less inhospitable. The planes would collect sunlight and store energy in rechargeable batteries and then transfer the energy to surface landers via laser power. The landers would convert the laser energy to electricity with converters\u2014an ambitious proposal that could one day power long-duration missions in hostile climes.<\/p>\n

Floating Above the Clouds of Venus<\/p>\n

Venus seems like an odd target for colonization. Surface pressure is 90 times that on Earth, and lead melts in the temperatures. However, around 31 miles above ground level, the atmosphere<\/a> is surprisingly Earth-like. Temperatures and pressures here are far more similar to Earth\u2019s, leading scientists to imagine floating cities or research stations cruising through the clouds.<\/p>\n

Venus is nearer to Earth than Mars, so trips will be shorter and cheaper. Its thick atmosphere offers more protection from cosmic radiation, and venturing into it could provide valuable data on climate change. Ramirez also notes that while it would be nearly impossible to mine the surface of Venus, the carbon dioxide gases on the surface could be piped out and converted into oxygen to support life on top.<\/p>\n

\u201cScientists would need to learn how to cope with the corrosive acid in the atmosphere and make the environment safe for aircraft,\u201d he says.<\/p>\n

\u201cThat way, if things go wrong, astronauts there would be safe.\u201d<\/p>\n

For Ramirez, the project is not merely about engineering\u2014it\u2019s about imagination and survival. \u201cI am excited to help pioneer UCF\u2019s vision to send humans to other worlds,\u201d he says. \u201cWe have the resources and money at this university to make large dreams like this a reality.\u201d His research combines planetary science and astrobiology with the purpose of finding out how planets are able to become habitable\u2014and how we can make new ones home.<\/p>\n

Practical Uses of the Research<\/p>\n

Research in terraforming could someday allow people to live beyond Earth, providing a backup long-term civilization. Techniques such as nanoparticle-based warming and in-situ resource utilization can lower the astronomical expense of bringing materials from Earth.<\/p>\n

These advances can also change how we do climate engineering<\/a> on Earth, from carbon capture to optimizing renewable energy.<\/p>\n

While planetary science pushes the study of habitability, it also propels technology, agriculture, and the energy system towards developments that can benefit space settlers as well as life on Earth.<\/p>\n
