Mars is the only planet in the solar system that is similar enough to planet Earth to possibly allow human habitation. The conditions, presence of water, and available minerals make it possible for humans to eventually live on Mars if we can develop the necessary technology and make the planet more human-friendly.
Certain characteristics of Mars make it the ideal planet to explore for colonization opportunities. Some of these characteristics are:
The Duration of a Day
The duration of a day on Mars is only a little bit longer than that of a day on Earth. This will make it easier for humans to adapt to Mars. However, a year on Mars is almost twice as long as a year on Earth. That will likely be a bit of an adjustment and having an Earth-born birthday may get complicated.
Similar Seasons to Earth
Mars has an axial tilt that is close to that of Earth’s. This means that the seasons on Mars are similar to that of the seasons on Earth. However, because of the year length that is much longer than on Earth, the seasons will last for more months than we are used to here on Earth.
The Area of Available Dry Land
The surface area of dry land on Mars is basically the same size as the dry land on Earth. It is a little smaller, but not with a lot. This makes habitation easier. The soil presents some problems because it is toxic to humans. Growing plants and food may not be possible without some preparation and extraction technology.
The Presence of Water Ice
It has been found through satellite images and the data captured by the Curiosity Rover that there is water in the form of ice on Mars. The polar caps are completely frozen. This means that there is water available for human use and that cultivation of food will be possible if we can remove the toxins from the soil. Water is a very crucial part of sustaining human life and this will be a key aspect when we decide to colonize Mars.
So, what are the differences from Earth that may make colonization difficult?
Mars is much smaller than Earth. You could fit more than 6 times the size of Mars into the Earth. This has implications for the number of people that will be able to live on Mars one day.
The Lack of Gravity
On Earth, we have gravity to keep us walking on the surface. Mars has only about a third of Earth’s gravity which means that we will float on Mars. If we are to live on Mars, we would need spacesuits to keep us grounded and help work against the lack of gravity. This obviously holds some interesting questions about human health and the working of certain equipment. Everything we have on Earth is built and functions with the knowledge that we have gravity. This will make things very interesting in Mars.
The average temperature on Mars is minus 80 degrees Fahrenheit. This is a lot colder than what we are used to on Earth. Summer on Mars will be several degrees hotter than on Earth and similarly, Winter will be a lot colder. This will be a condition that spacesuits will have to take into account. We will likely learn to adapt and our bodies will get used to the temperatures, but it will take time.
Less Sun Exposure
Humans need sunlight to survive. So does the plants and animals that make up our ecosystem and food pyramids. Mars receives approximately 50% less sun exposure than Earth. This will also have implications for our survival on Mars. It will also influence the ability to generate electricity through solar panels. Luckily, these are things that can be resolved with technology and planning.
The Thin Atmosphere and Lack of Magnetic Field
Earth has a magnetic field that protects us from space debris, asteroids, radiation, and other such dangers. Mars does not have a magnetic field to perform this very important function. Its atmosphere will offer some protection from cosmic storms and incoming meteorites, but we will be more exposed than we are on Earth. The thin atmosphere means that we will be exposed to radiation and unfiltered sunrays.
Most of the atmosphere on Mars consists of carbon dioxide. A very small percentage of the atmosphere is made of oxygen. There are some nitrogen and argon and that’s about it. With the right technology, we will probably be able to create or extract oxygen from the carbon dioxide that is present. However, the majority makeup of carbon dioxide means that we will not be able to live and breathe on Mars without oxygen masks.
Human colonization of Mars is something that is definitely part of our future. It may be several decades or even millennia away, but it is likely to happen. At the moment, the differences between Earth and Mars are more than the similarities. However, technology can help address most of the challenges. The necessary technology just needs to be developed and tested. Once the funds for such development are assigned to Mars exploration and colonization, the technology development will happen fast.
So, now you know what the differences and similarities between Earth and Mars are. You can learn more about Mars and its conditions here. Also, have a look at the plan NASA has set forth for making a manned mission to Mars a reality.
Expeditions to Mars seem to be high on the universal priority list. The biggest obstacle at the moment is the cost of everything involved with planning and preparing for a trip to Mars as well as the actual expedition. Different countries and individuals are working towards making a trip to Mars a reality. Most of them are aiming to realise this by 2030 and some say even before that.
But what exactly is the fascination with Mars and humans living on it? Mars is not exactly a friendly environment for humans to live. So why do we want to? There are several reasons why putting humans on Mars is a good idea. The process of getting people there and making it so that we as humans can live there will be a long one. The good news is that it is not impossible. All the technology that needs to be developed to make it happen is within our reach already. Like we said before, it’s just all about the money.
Let’s have a look at some of the reasons why we want to go to Mars so badly.
Mars can be our backup planet and help to make humans an interplanetary race. This is something that will make us pioneers and help to solve some of our resource problems. Since the climate problems became apparent, countries across the world have tried to find alternative fuel sources and other solutions to our Earth problems. We are running out of certain resources and we are destroying the atmosphere with our current behaviors and consumerism. Establishing a human colony on Mars may be the answer to some of these issues. Harvesting resources will help us with water shortages.
For it to be a backup planet where humans can live for a long time we need a lot more technology and a lot more time, but we’re pretty sure it will happen. If Earth became so bad that humans can no longer live there, Mars would be the best option for a backup planet that will save us from extinction.
Mars represents the next big step in the exploration of the universe. Humans have a great sense and spirit of exploration. We always want to know more and learn more about the things that are unknown and yet to be discovered. It is this human characteristic that has gotten us to the point where we are today. We have technology that few could have imagined a century ago. Our medical technology is saving lives like never before. We know more about the universe and what is out there than ever before. Going to Mars and exploring it will just be the next step in this eternal need for more knowledge and exploration.
Knowing more about Mars can make us improve life on Earth. It is clear that we will need a whole lot of new technology to make it possible for humans to travel to Mars and survive there. The great thing about developing these new technologies is that it will likely bring about advancements and new discoveries in other areas as well. The algorithm that fixed the blurry images from the Hubble Telescope changed the way doctors detect breast cancer. Any new technology and developments will have positive discoveries as a result.
All the work and money that will go into exploring Mars will be well worth the advancements and improvements they can lead to for us on Earth. The only way we can move forward as a people and a planet is to go beyond what we know and go where we haven’t been before.
New discoveries in space and on Mars will inspire future generations. One of the most effective ways to inspire students to explore science and technology as career fields is space exploration. Whenever we make new discoveries or reach new destinations, children and teenagers all over the world become inspired and want to be the next person to go to space or the moon or Mars. We need inspired young people to continue making new discoveries and pushing the limits of exploration and human exploration. These types of exploration take decades and centuries to complete and the future generations of curious minds will keep leading us forward to bigger and better things.
Studying Mars and its history can make us understand Earth better. We already know that Mars was once a planet much like Earth. It was warm and had a lot of water. Mars is the planet most like Earth in our solar system. Learning about what happened to mars to reduce its atmosphere and make it become the way it is today, can tell us if we need to prepare for the same things. If we know more about Mars, we can understand what things may lay ahead for Earth or even develop ways to prevent these things from happening.
A successful mission to Mars and an advanced space program will keep America at the top. A mission to Mars also has economic and diplomatic advantages. The country or countries that will be involved in the mission to Mars will be world leaders and open up a whole lot of economic opportunities. If another country were to win the race to Mars, America and the other participants will face some harsh realities and will have to accept their fate as second-best. Being at the front of the exploration and colonization of Mars will have several advantages. Being anywhere other than the front may be less glamorous and less lucrative.
It is clear that are many reasons why we want and need to go to Mars. All of these reasons will take the world as we know it to a new level and help us make more amazing and useful discoveries. If you ignore the enormous price tag that will go with this Mars mission and everything related to it, it seems that it will only have advantages for humans and planet Earth. Only the future will tell where we will go, but it seems inevitable that we will put humans on Mars in the next few decades.
Human survival on Mars is a long way off. Many things still need to be researched and developed before we would be able to successfully and safely live on Mars. NASA’s three-part plan involves the research and experiments to test what we would need and how we would have to adjust our daily lives to survive on the generally uninhabitable red planet.
Many authors and scientists have tried to predict or explain how life on Mars would be. Based on the facts that we do have about Mars, many of these depictions could be very close to the truth. NASA has had teams of astronauts living in conditions that closely mimic what life on Mars would be like. They monitor these astronauts and their reactions and interactions. They gather data throughout the experiment and also interview the astronauts afterwards to learn how they experienced the process mentally, physically and psychologically.
Mars, unlike Earth, is not human-friendly. It has temperatures far below zero degrees, it is extremely dust, it has a very thin atmosphere and a lot of radiation and it has low gravity. For Mars to be habitable for humans, a lot of changes will have to be made to its surface. Before that can happen, we would need to find ways to create oxygen from Mars’ carbon dioxide and get water from the frozen rivers. We would also need to have spacesuits that protect us against the radiation.
Landing on Mars is one of the big issues that NASA and others are working to address. Because of the lack of gravity, landing is a tricky thing. Many different ideas have been put forward on how to solve the problem. The latest idea involves retro-propulsion technology combined with parachutes. By the time we can actually go to Mars, there will be more and other ideas to make landing a heavy spacecraft on the surface of Mars.
Humans will not be able to just live on the surface of Mars as we do here on Earth. The planet is currently able to sustain human life and is, in fact, a very hostile environment. Different possible habitats have been designed in an attempt to sustain human life. Each of these designs will likely have a few things in common:
- Sealed for protection from radiation and against the thin atmosphere
- Life-sustaining without help from Earth
The habitats will be necessary to keep humans alive on Mars until terraforming is completed. Terraforming is the process in which humans can cultivate Mars to the point where it will be able to sustain human life without assistance. We would be able to walk on the surface without a spacesuit.
The film, The Martian, which was recently released, portrays the types of habitats that NASA is looking to create. It also shows several other pieces of equipment and technology that are quite accurate to what is actually being studied and built.
To survive on Mars, we will need a lot of technology and equipment. Some of these will include:
Habitats – Life-sustaining habitats that can support human life without having supplies from Earth on a regular basis.
Storage Facilities – These facilities will be necessary for extra equipment, fuel, food, and spacecraft.
Extraction and other equipment – Mars has a lot of useful resources that can be used to make the planet more habitable and also help Earth with the possible depletion of resources like water. Equipment to extract and transform or use these resources will be very important. This will be one of the main missions for the people living on Mars.
Food Technology – To survive we need food. Equipment for food production, harvest and storage will be necessary. There are many obstacles to growing food on Mars and there will need to be equipment and methods to successfully do so.
Energy Production and Storage – Energy will be very important. Equipment for harnessing energy and storing that energy will be crucial.
Communication Equipment – Another very important aspect is communication equipment. It will be vitally important to remain in contact with Earth and the people in charge of the mission.
Sending packages from Earth to Mars will be an extremely expensive process. Therefore, it will be better to farm on Mars. However, Mars has soil and dust that is toxic to humans. Furthermore, there is much less sun and the soil doesn’t have the organics needed to grow. Luckily, the soil does have the minerals required for growth and with some small adjustments, we would be able to farm on Mars. Because of the soil toxicity, methods and equipment will be needed to ensure that the food farmed and harvested are safe to eat. Humans will also have to make use of the ice-capped poles on Mars. Because of the low temperatures, most of the water is in ice form and will need to be made into water.
In reality, it is possible for us to do these things and sustain human life on Mars. Well, not yet, but once the technology is developed, it is possible. The only thing holding us back from getting to Mars is funding and the development of technology. Once these things fall in place, it will be no time until we send the first humans to Mars.
Many things must still be done and developed to realize this mission. Once humans are on Mars, it will take many years to make it habitable for more of us. It is unlikely that Mars will become a home to humans within our existing lifetime, but our great-grandchildren may well have that option.
It is intriguing to imagine a life on Mars. It would be fundamentally different from life on Earth because of all the challenges and dangers. People living on Mars will have their own laws and ways of doing things. One day, science and technology will make it happen.
NASA has been working on plans to go to Mars for a very long time. A few years ago, they announced their three-part plan to make it happen. This plan involves different stages of getting humans closer to Mars concluding with us stepping on Mars and exploring the potential of colonizing the red planet. The different stages are planned according to the development of technology and other capabilities. Most plans aim to have a manned mission to Mars in the next decade, so we can look forward to some exciting times in the 2030s.
The race to send a manned mission to Mars is an important one for different reasons. It holds economic advantages, collaboration promises, and much more. It also poses the potential to be a solution to problems with depleting resources and climate change.
Stage 1: EARTH RELIANT
The basic idea of this stage is research and experimentation. It involves research conducted on the International Space Station as well as areas on Earth that are similar to Mars. Astronauts stay in isolated areas where the conditions of Mars and isolation are mimicked to see what the effects are on them. The journey and stay on Mars will have both physical and psychological effects and this stage helps NASA learn more about the potential effects.
Some of the tests and research that are being conducted include improving advanced communication systems technology, material flammability tests, life support systems, 3D-printing, in-situ resource utilization development, and the effects on human health and behavior. Tests to improve space suits are also being conducted. When we do get to Mars, we will be exposed to radiation, the toxic dust from the planet surface, and who knows what else. The spacesuits our astronauts will wear needs to protect them
Stage 2: PROVING GROUND
This stage involves experiments in deep space. Astronauts will perform complex operations in the Moon’s orbit which is called cislunar space. This will enable them to perform operations and learn what will be necessary to travel as far as Mars and survive. Several exploration missions and operations will be conducted. One of these is the Asteroid Redirect Robotic Mission that is planned for 2020. A robot will collect a boulder from a near-Earth asteroid and then astronauts will study it and learn as much as they can.
Other projects will involve developing and testing state of the art information technology solutions and systems testing for a deep-space habitation facility. Research and development will also be done to find the best ways to make use of reduction, reuse, and recycling to reduce the constant need for new materials.
A new rover robot will be sent to join the Curiosity Rover in 2020. The new rover will feature a whole bunch of new and exciting gadgets that will enable us to learn more. A big part of the preparations for a Mars mission is the attempt to make oxygen from the carbon dioxide in Mars’ atmosphere. One of the new gadgets will be MOXIE and its main purpose is to try and make oxygen on Mars.
Stage 3: EARTH INDEPENDENT
The last stage of NASA’s mission to Mars plan is the EARTH INDEPENDENT. This entails sending humans to the vicinity or orbit of Mars, its moons and eventually Mars itself. All the information collected from the research on the International Space Station and the experiments and missions in deep space will be used to help send humans to Mars. The estimated timeline aims to put the first people on Mars in 2030.
The mission will be done as a collaborative effort between NASA and other countries and organizations. The mission is too big to be handled by a single organization or country. Not only will it require large amounts of money, but also the knowledge and information gained by different entities.
This stage involves having humans stay on Mars for a long period of time. They will attempt to grow food, create oxygen, and support human life. It will take some time to cultivate and prepare Mars to sustain several humans. A big part of the process is to improve communication and information technology to such an extent that interaction between Earth and Mars will be possible and easy.
A mission to Mars requires the development of several new technologies and equipment. When people land on Earth, they will need to be prepared for the harsh conditions and know how to survive. This will be a risky mission, but it is all worth it if it means we can expand the human race and gain resources.
The biggest problem with the Mars mission is the costs. It will be an exceptionally expensive mission and that is why collaboration will be needed. Some private organizations are funding their own projects and are aiming to beat NASA to Mars. One of these private entities is SpaceX run by Elon Musk. He aims to send humans to Mars within the next 10 years or so.
A mission to Mars is within our reach. Living on Mars is also a definite possibility, but that will probably only happen many years in the future. Sustaining a human population will take hundreds and maybe even thousands of years. There are still many years of research and experiments to be done before the dream of living on Mars can become a reality.
If you would like to get an idea of what it would be like to live on Mars, read this article about the books and films written about living on Mars.
Science and technology have brought us a long way in understanding the world and the universe. We know things about our planet and the other planets in our solar system that we never thought possible. It is truly amazing and fascinating. One thing, however, is still eluding the human race. We have yet to send a manned mission to Mars.
Many countries and organizations are working towards sending people to Mars as soon as possible. There are many reasons why exploring and possibly colonizing Mars is important for us as humans. There are some reasons why this type of expedition has not been possible.
Lack of Technology
The technology needed to make a manned trip to Mars possible is within our means. It will be costly and take some time to develop, test, and perfect, but it is absolutely possible. The lack of technology creates problems across different areas.
Mars is a long way from Earth and it will take several trips to get everything needed for humans to survive on Mars. Current plans include sending supply craft and building parts ahead of humans. When they land on Mars, we will then assemble the equipment and housing. It will take a long time to get enough spacecraft to do this and develop the necessary technology to build housing to sustain human life.
Apart from the number of trips that will be necessary, the distance also presents a problem in terms of keeping humans alive in space. If we were to travel to Mars, it will take months. This means that new ways of storing food and carrying enough aboard a spacecraft to sustain several people will need to be created. Without enough food and stored resources, humans will not outlive the trip to Mars that is estimated at approximately 30 months.
At the moment, there are no rockets that can make the trip to Mars without damage or getting destroyed. There are several reasons for this. First of all, the lack of gravity and atmosphere on Mars makes landing an extremely difficult process. Secondly, the weight of a rocket that is carrying humans and supplies will very likely crash to the surface of Mars and make the whole trip a big mess. The space fleet has been retired and building new rockets that are small enough to land and can carry enough weight at the same time will cost a lot of money and take quite a bit of time.
Fuel storage is another important gap. Technology needs to be developed to store enough fuel for human survival as well as the several trips that will be required from Earth to Mars and back. Fuel will also be needed on Mars for vehicles and equipment. This will be an expensive fuel situation. Other dangers involved with fuel storage include that it can easily explode in space if not secured and stored well enough. Space temperatures can make fuel act unpredictably and cause explosions.
In-Situ Resource Utilization
Mars has many useful elements and materials. These can be used by astronauts or humans who go to Mars. They could cultivate these elements to farm and create oxygen. However, the technology for this is not yet developed. In-situ resource utilization (ISRU) basically means living off the land. This is a process that NASA and others are looking at for feeding people when on Mars. Plans include the development of a machine that can extract oxygen from the carbon dioxide on Mars. It also includes harvesting and utilizing other minerals for fuel and building materials. There is still a lot to look at with this as the soil on Mars is believed to be toxic and we will not be able to eat food grown in it.
The biggest concern about travelling to Mars is the effect it will have on humans. We don’t yet know enough about the effects of travelling and living in space. We can only predict and prepare based on what we now. Concerns that will have to be addressed include:
Being weightless for long periods will influence the human body. Astronauts who were in space for several months came back with decreased bone density and low calcium. Some also showed signs of blindness. There is too much about the influence of space that we don’t yet know and understand.
When we live on Mars, we won’t have the Earth’s atmosphere to protect us against radiation. Mars has a very thin atmosphere and space radiation will be a big problem. Before humans can be sent to live on Mars, we will have to find a suit or some other equipment to protect us against radiation properly.
One of the biggest psychological challenges as indicated by astronauts during real space trips or simulated ones was the isolation. You don’t have contact with the outside world. Chances are that when you live on Mars, you may not hear from your family or friends again for a long time. You won’t be able to send them text messages or email them. The infrastructure for such things will still have to be developed. You will have others around you, but you will all experience isolation from the planet that you grew up on and everyone you left behind.
Technology will need to be developed to properly isolate humans from their surroundings. It is very likely that we as humans can contaminate Mars and we don’t know if Mars can cause contamination for humans.
Dust damage is another big concern. It will likely cause a lot of damage to equipment and their moving parts. It will make maintenance very difficult. The dust may also be toxic to humans which bring about its own set of issues. The dust may cause allergies, pulmonary problems and can even contribute to causing cancer. Theradiation already increases the chances of cancer.
Cost and Collaboration
Costs to make a manned trip to Mars a reality will be enormous and will require international collaboration. There is no way that one country will be able to pull it off on its own. Many political issues will need to be sorted and the changing nature of politics and economics will need to be considered when collaborations are negotiated.
Legal, Ethical, and Societal Issues
Apart from all of these issues, we still need to keep in mind the legal, ethical, and social concerns that will also arise. The rules, laws, and societal norms on Mars will be vastly different from those we have on Earth. All of this must be considered and planned for.
As you can see, there are many issues that need to be resolved before a trip to Mars can be realized. The technology is within reach and the other problems can be researched and refined. The biggest issue remain the resources required to develop and perfect everything that will be needed.
The planet Mars has fascinated people around the world for centuries. Philosophers, scientists, astronomers, and of course writers have all tried to learn more and try to predict how it would be to live on Mars. Many authors have written science-fiction books depicting the way they think life on Mars would be like. Authors often make use of actual facts to base their stories on which means that some of these science-fiction depictions may not be so far from the truth.
In order for us to have any type of idea of what it would be like to live on Mars, we must read about what others think it would be like. Obviously, these books are fiction, but many fiction books have some reality in them. Whether the depictions are accurate or not, we believe that you will enjoy the books on our list and that they will definitely get your mind going about living on Mars.
Our Mars-related book suggestions:
1. Mars Trilogy by Kim Stanley Robinson
Red Mars, Green Mars, and Blue Mars make up the award-winning Mars Trilogy written by Kim Stanley Robinson. The series may be the most realistic depiction of what it would be like when humans finally attempt to colonise Mars. The stories are gripping and have been on the top of literature lists since its publication. The story takes us from the small party of scientists, adventurers, and others that start the process of terraforming through many trials, catastrophes, human conflicts, and more. This is definitely one of the books you must read.
2. How We’ll Live On Mars by Stephen Petranek
Stephen Petranek is an award-winning journalist that believes we will be living on Mars by 2027 and that is both plausible and inevitable. In this book, he explains why colonising Mars is a good backup plan for human life and also how he thinks it will happen. Petranek tells a riveting story and combines real-life interviews, keen reporting, and research to prepare us for living on Mars within the next decade.
3. The Martian Chronicles by Ray Bradbury
The Martian Chronicles were the first science-fiction books written after science and technology learned that Mars was basically a lot of red dust. Ray Bradbury tells stories in a beautiful way and you will struggle to put these books down. His stories are imaginative and explore a whole range of interesting and sometimes haunting possibilities of living on Mars.
4. Mars Life by Ben Bova
Ben Bova has a whole range of books that speculate and explore the possibility of colonizing other plants, including Mars. Mars Life follows a geologist and a crew of scientists on their journey to and across Mars. As it goes when humans are involved, the story has twists and turns and shows the struggles between money, politics, belief, science, and more that will follow no matter on which planet we live.
5. The Sands of Mars by Arthur C Clarke
This was one of the first novels written about mars. We have learned a lot more about Mars in the decades since this book was published. However, at the time that it was written, it was remarkable and stayed true to the facts we knew at that time. The story follows a reporter who voyages to Mars to write about the colonists and during his journey he comes across native Martians. It is a great story to show the contrast of what we knew then and what we know now.
6. Falling Stars by Michael Flynn
Falling Stars is the final book in the Firestar Series about why humans should leave Earth. The book is based on the belief that humans will go extinct if don’t find ways to live on other planets. Obviously, it is not a simple feat to move humans to other planets. Ethics, politics, religion, and societal norms will inevitably come into play and complicate things. The series follows humankind in its quest to overcome these issues and become an interplanetary and superterrestrial race.
7. Moving Mars by Greg Bear
Moving Mars is another award-winning book on this list. Together with Red Mars, it renewed interest in colonising Mars in the 1990s. It centersaround the idea that when we colonzse Mars there will inevitably be conflict between Mars and Earth. Mars is portrayed as the open-minded and radical side that clashes with Earth and its conservative way of seeing things. It is a high-tension novel that will keep you riveted until the last page.
Other titles that you can read for ideas and see how opinions have changed include Destination Mars by Hugh Walters, The Martian Way by Isaac Asimov, Voyage by Stephen Baxter, and Red Planet by Robert A Heinlein.
Besides these science-fiction novels, many documentaries and movies have also been made about living on Mars. A few that are worth watching include:
- Total Recall starring Arnold Schwarzenegger made in 1990. It is loosely based on a short story by Philip K Dick.
- Mission to Mars made in 2000. It is a science-fiction thriller centeredaround the failure of the first manned mission to Mars and the rescue mission that follows.
- Race to Mars made in 2007. This is a documentary miniseries produced by Discovery Channel Canada about the red planet.
- The Martian made in 2015 and based on the novel by Andy Weir. This is a more recent film that depicts Mars more in the light of what we know already.
- Marsmade in 2016. This is a docudrama miniseries that was made by National Geographic. In the series, they combine real interviews with fiction to create a story of the first astronauts to travel to Mars to explore and colonise it. The film is based on the novel How We’ll Live on Mars by Stephen Petranek.
These novels and films are just the top of the iceberg of works about Mars and humans living on the red planet. Mars is truly a fascinating planet and the stories and depictions of what it may be like are amazing and sometimes scary. If you want to know more about the world’s fascination with Mars and why we need to colonise it, you must read these books.
Mars is an interesting planet. It is also called the ‘Red Planet’ because of its red outward color. Mars has characteristics that relate to Earth which makes it an interesting option for habitation. Mars is the fourth planet from the Sun and also the second smallest. It was first recorded by Egyptian astronomers approximately in the second millennium BC. Let’s look at some of the other facts about Mars.
Mars received its name based on mythology and the color of its surface. Its red color is the result of the rock and dust that are rich in iron. The Greeks called it Ares after their god of war. The Romans followed suit and called the planet Mars after their god of war that was associated with the color red and that is how we now refer to it. Other cultures and countries also named the planet based on its red color. The Egyptians called it ‘Her Desher’ which means ‘red one’ and the Chinese referred to it as ‘the fire star’.
Mars is what we call a terrestrial planet. It has a thin atmosphere that consists mainly of carbon dioxide. Other elements that make up Mars’ atmosphere include argon and nitrogen. It is said that the atmosphere was thicker at one time but that it was damaged by storms. When compared to Earth, more than six of Mars will fit into the volume of the Earth. Mars has two moons.
Days and Years
One year on Mars is equal to 1.9 years. This means that a year on Mars is equal to 687 days compared to an Earth year that is 365 days. One day on Mars is 24 hours and 37 minutes compared to the Earth’s days that are 23 hours and 56 minutes. This is good news for when we finally go to live on Mars as the days won’t be that much longer.
The temperatures on Mars are extreme and create a very hostile environment for any living thing. The average temperature you can expect on Mars is -81 degrees Fahrenheit compared to the average of 57 degrees Fahrenheit on Earth. Like I said, it is an extreme and hostile environment.
Mars has two moons that are called Phobos and Deimos. They were named after the horses that pulled the Greek god of war’s chariot. American astronomers discovered the two moons in 1977. Scientists believe that the two moons are asteroids that were captured. This is based on the similarities of the moon surfaces to those of asteroids found in the outer asteroid belt.
Mars and Earth
Mars is being considered as an ideal planet for humans to expand to. Despite the drastic temperatures and other unfriendly conditions, some things about Mars are similar enough to make living there a possibility.
One of the similarities is the landmass. Earth and Mars have approximately the same landmass. About two-thirds of the Earth’s surface is covered with water and scientists believe that Mars was also once covered with water. The gravity on Mars is less and you will be able to leap about 3 times higher than on Earth. You will also weigh a lot less on Mars.
Scientists could start studying Mars before missions were attempted because of rocks falling to Earth. Meteorites from Mars have orbited Earth for millions of years before falling to Earth. Scientists picked up on these debris pieces and were able to start studying Mars and its profile before any contact was made with the planet.
Missions to Mars
NASA and other parties have been trying to put people on Mars for decades. There are several reasons why it has not yet succeeded. The attempts to discover more about Mars started during the mid-nineties and the first spacecraft was sent there in 1960. Since then, there have been approximately 68 missions.
Since 2014, 40 missions to Mars were attempted of which only 18 were successful. When we talk about missions to Mars, it refers to sending orbiters, rovers, and landers and also flybys. Missions fail for different reasons including the distance of Mars from Earth and a lack of specific technology.

Mars is unique in many ways and despite its small size compared to the other plants in the solar system, it holds a few records. It is home to the tallest mountain in the solar system. The mountain is called ‘Olympus Mons’ and is in actual fact a shield volcano that is believed to still be active.
Mars is also at the top when it comes to dust storms. The storms on Mars are especially bad and can last for months. The main reason for the severity is because its trips around the Sun take longer than most other planets.
Every two years, Mars appears to be moving backwards or from east to west. This is called retrograde. Retrograde is an illusion that occurs because of the way in which Mars and Earth orbit the sun. In earlier years, astronomers found this phenomenon very strange and tried to find some mystical meaning for it. Today, we know that it is simply an illusion that takes place every two years for a few months.
Putting People on Mars
For many decades now, NASA and other organisations like SpaceX have been working on putting people on Mars. One of the reasons is to have a backup planet in case Earth ceases to exist and another is to make the human race inter-planetary. Despite the many decades of studies and sending spacecraft to Mars, we are still unable to get humans to Mars. There many different reasons for this and we discuss this in a later post. However, despite the setbacks, it seems that people are more determined than ever to make putting people on Mars a reality.
Mars is a fascinating planet. Despite its harsh conditions, scientists and researchers believe that it will be possible for humans to live on Mars if we had the right technology. So, the experiments and the quests continue and some predict that we will be able to go to Mars within the next decade or so.a
