Is it possible that at some point we will create Mars like Earth? – Tyla, 16, Mississippi
When I used to be in middle school, my biology teacher showed our class the science fiction film “Star Trek III: The Search for Spock.”
The plot captivated me with its portrayal of the “Genesis Project“” – a brand new technology that transformed a dead alien world right into a world vigorous.
After watching the movie, my teacher asked us to write down an essay about this technology. Was it realistic? Was it ethical? And to channel our inner Spock, was it logical? This task had a huge effect on me.
Fast forward to today, and I’m an engineer and professor Development of technologies to expand human presence beyond Earth.
For example: I’m working on advanced propulsion systems to take spacecraft beyond Earth orbit. I’m helping to develop lunar constructing technologies to support NASA's goal of long-term human presence on the moonAnd I used to be in a team that showed How to 3D print habitats on Mars.
Providing supplies to people beyond Earth would require an ideal deal of time, energy and imagination, but engineers and scientists have begun to deal with the various challenges.

An incomplete checklist: food, water, shelter, air
After the Moon, Mars is the subsequent logical place for humans outside of Earth.
But is it possible to terraform Mars – that’s, to remodel it into something more like Earth and support life – or is that this only a fantasy from science fiction?
To continue to exist Mars, humans need liquid water, food, shelter, and an environment that gives enough oxygen to breathe and is thick enough to retain heat and protect against the sun's radiation.
But the Martian atmosphere is just about all carbon dioxidepractically without oxygen. And it is vitally thin – only about 1% as dense because the Earth.
The thinner an environment, the less heat it could actually store. Earth's atmosphere is thick enough to store enough heat to sustain life. just like the greenhouse effect.
On Mars, nevertheless, the atmosphere is so thin that the temperature recurrently drops to -101 degrees Celsius (150 degrees Fahrenheit below zero) at night.
So what’s the most effective method to give Mars an environment?
Although there are not any lively volcanoes on Mars – so far as we all know – scientists could trigger volcanic eruptions through nuclear explosions. The deeply trapped gases in a volcano can be released after which drift into the atmosphereBut this plan is a bit crazy since the explosions would also release deadly radioactive material into the air.
A greater idea: redirecting water-rich comets and asteroids in order that they crash into Mars. This would also release gases from the planet's subsurface into the atmosphere and at the identical time release the water contained within the comets. NASA has already shown that It is feasible to redirect asteroids – but to attain something, relatively large ones and plenty of of them are needed.
Making Mars comfortable
There are quite a few ways to heat up the planet. For example, giant mirrors in-built space and placed in orbit around Mars could reflect sunlight onto the surface and warm it up.
A recent study suggested that Mars colonists could spread Aerogelan ultralight solid material, on the bottom. The aerogel would act as insulation and retain heat. This could occur anywhere on Mars, including the polar ice caps, where the aerogel could melt the prevailing ice and create liquid water.
To grow food, you would like soil. On Earth, soil consists of five ingredients: minerals, organic substances, living organisms, gases and water.
However, Mars is roofed by a layer of loose, dust-like material, RegolithThink of it as Martian sand. The regolith accommodates few nutrients, not enough for healthy plant growth, and it accommodates some harmful chemicals. so-called perchloratesused on earth in fireworks and explosives.
Clean the regolith and transform it into something usable wouldn’t be easyWhat foreign soil needs is a Mars fertilizerpossibly by adding Extremophiles robust microbes imported from Earth and survive even the harshest conditionsGenetically modified organisms are also a possibility.
Through photosynthesis, these organisms would begin converting carbon dioxide into oxygen. As Mars eventually became more hospitable to Earth-like organisms, colonists were in a position to introduce more complex plants and even animals.
Providing oxygen, water and food in the precise quantities is incredibly complex. On Earth, scientists have tried to simulate this in Biosphere 2a closed ecosystem with ocean, tropical and desert habitats. Although all habitats in Biosphere 2 are controlled, even there scientists struggle to seek out the precise balance. Mother Nature really knows what she's doing.

A house on Mars
Buildings may very well be manufactured using 3D printing. First, they’d need to be pressurized and guarded until temperatures and air conditions on Mars are much like those on Earth. Technologies for the autonomous construction of planets from the Moon to Mars The program explores how exactly this could be achieved.
There are many other challenges. For example different from the earthMars has no Magnetospherethat protects a planet from solar wind and cosmic radiation. Without a magnetic field, an excessive amount of radiation penetrates for living beings to stay healthy. There are Possibilities for generating a magnetic fieldbut to date the scientific status could be very speculative.
In fact, all the technologies I even have described are far beyond the present capabilities required to terraform Mars. Their development would require enormous amounts of research and money, probably far more than is feasible within the near future. Although the Genesis device from Star Trek III could terraform a planet in a matter of minutes, terraforming Mars would take centuries and even millennia.
And before we start turning Mars right into a second Earth, many ethical questions have to be addressed. Is it right to alter one other planet so drastically and permanently?
If all this disappoints you, don't be. As scientists develop innovations to terraform Mars, we'll also use them to make life higher on Earth. Remember the technology we're developing to 3D print habitats on Mars? Right now, I'm a part of a gaggle of scientists and engineers using that very technology to print homes here on Earth – which is able to help solve the issue. Housing shortage on the earth.
