Mars is absolutely nothing like Earth
Mars propagandists create the impression that Mars is equivalent to Earth.
Mars propagandists have created an impression that Mars is somehow like the little brother of Earth, that the planet somehow deserves our help to set things right – get the atmosphere back, help him out with that missing magnetic field. They imply that Mars and Earth are somehow equals, and this creates powerful misinformation about the right relationship that we ought to have with Mars. Earth is not just a convenient rock that we ended up on – we evolved here – and no other planet is ‘Earth-like’ not even one with a breathable atmosphere. Mars is as similar to Earth as a bee hive is to a similarly sized rock.
Transition to Sustainable Energy
Fixing Earth is the priority right now.
If we are to meet the Paris targets for climate change, we need to make substantial changes to the world's energy supply. This is going to require massive amounts of money, new technology, engineering expertise - all the things that are being sucked up for the Mars Mission. Mars is a major distraction from sustainability and offers nothing in return.
Money, Money, Money
Billions of dollars will be wasted, that ought to be spent on pressing needs.
To date, a minimum of $20 billion has been spent investigating Mars, and recently Trump okayed $450 billion over 30 years to get humans to Mars. That's $450 billion US dollars. There is the opportunity cost for every dollar spent on Mars. Just for a moment think of the good that nearly half a trillion dollars could be spent on – health, education, environment. Instead, how about we spend half a trillion dollars educating young girls in developing countries how to create entrepreneurial ventures planting trees, for example. That’s a much better use of the money.
Very Little Public Support
Apart from scammy questionnaires, there is no evidence of substantial public support.
Apart from the handful of people who say that they want to go and live on Mars, there is very little public support for the idea. Sure, there are some scammy questionnaires that guarantee the right answer. But very few people who are informed of the details support the idea.
Cost of Rescue
It will cost billions to put humans on Mars, assuming everything goes right.
In the movie The Martian, the Martianaut was left for dead on the planet. Later, when it was discovered that he was still alive, a mad-cap rescue mission was launched. If getting to Mars is going to cost at least $450 billion assuming that everything goes right, how much much extra will it cost when something goes wrong, and who will pay. Mars is a massive blank-check.
Brain Drain
Huge amounts of human talent are wasted on the dead planet.
Today, there is a desperate need for innovation and technology development to help protect the global environment - we need to renew our energy supplies and move away from petroleum based-materials. The Mars program is a huge brain drain, sucking talent away from where it is needed most. Where we need the research effort is in renewable energy technology with a 1,000 to 1 energy return of energy invested (EREOI), super-powerful ecofriendly batteries, bio-plastics and sustainable biofuels. There are thousands of fields of inquiry that actually benefit humans and the natural living systems of the planet that we live on that are not getting studied because so much talent is being squandered on Mars.
Stratospheric soot
Some Mars rockets pose a huge global warming problem.
Rockets burning methane or kerosene and liquid oxygen have a relatively benign carbon footprint - equivalent to a long haul flight. However, solid rocket boosters – such as the NASA SLS booster - produce huge amounts of soot. When this soot enters the stratosphere, particles have a long residence time (decades to centuries), and because soot has a massive global warming potential, stratospheric soot from heavy launches presents a potentially huge global warming problem. The fact that NASA would even consider, let alone build such a device shows the depth of psychopathy that has invaded this industry. It's time to put Understand and Protect our Home Planet into the NASA Mission statement.
Plutonium and other radioactive materials
Many Mars missions rely on plutonium.
Every bit of plutonium send to Mars has to be mined and processed on Earth, and that affixed to the top of a slow burning bomb (rocket) and blasted through the atmosphere at thousands of miles an hour. The risk of an accident that sees the launch fail and plutonium burn up in the atmosphere is too high. This has already happened on at least three occasions including Phobos-Grunt, Cosmos-954, Snap 9-A. So while the space agencies, corporations and Mars aficionados get the benefit of the money spent on Mars, it is the rest of the humans who suffer from the radioactive contamination of the production and potential accidents of these fuels.
Pollution in production, launch and debris re-entry
Rockets have a huge environmental footprint.
Rockets and space craft are engineered structures that have a huge supply chain that originates in a mine somewhere. There is huge amounts of energy and minerals that need to be processed and at every stage, there is an environmental footprint. From production of space vehicles. launch and the re-entry debris the Mars program assaults the earth biosphere with environmental pollution, and there is no budget allocation to clean up the mess.
Fake News about Mars is Rife
The public is largely ignorant about Mars because they are misinformed.
Propaganda is already intense and pervasive… Check the dog in a space helmet by Musk, and the NASA Promotion: Mission to Mars. Because of climate change, Planet Earth is heading into an era of great trauma. Sea level rise, intense storms, deeper droughts and floods.
Mars Propaganda Death Spiral
The public is largely ignorant about Mars because they are misinformed.
Earth is heading for collapse, and the worse it gets on this planet, the easier it will be to make Mars seem rosy. This phenomena - the Mars Propaganda Death Spiral - could trigger a panic among funding agencies, who will then see Mars as the 'only hope for humanity', which will in itself be the death knell for humanity.
Humans are Not Mature Enough
Human race is not mature enough to embark on this mission.
When humans first visited the Moon and planted a flag, it wasn't a flag that represented all the humans on Earth, or all of life on Earth, it was a flag that represented a tiny subset of humanity: American flag. At this stage of our cultural development, humanity is simply not mature enough to embark on a venture, like this.
Spiritual Void
Earth is our evolutionary and biological home in the Universe.
When we view the biosphere simply a device that performs a function - the way we view an electrical appliance - we lose our spiritual connection to Earth, and we descend to the level of high-tech-apes. We humans co-evolved with millions of other species over billions of years in 1-G gravity, protected by a magnetic field and an ozone layer. For humans to prosper, it is important that we retain the spiritual bond between the humans and Mother Nature. The Mars colonization program breaks the spiritual bond between humans and mother nature by suggesting that any-old planet will do for us humans.
We ought to settle the sea floor instead
There is absolutely zero ecological benefit to going to Mars.
Settling the seafloor is of equal an engineering challenge as Mars; it just involves high pressure, rather that low pressure. It is likewise dark and hard to reach. The upside is that there is lots of seafood, and it will actually do something good for humanity by fostering environmental science. Plus, if you want to avoid collapse and nuclear fallout, the Abyssal Plain is as good a place as any. You don't need solar panels, just capture the moving water for energy. If you get in trouble, just ascent three kilometers, and you’re back in the air again. A recent NASA education series titled Ocean Worlds invites us to learn about the oceans on other planets. If only we care so much about the oceans of earth that are overheated, over fished, acidified and contaminated with micro-plastics – some of which comes from the trash of the space industry that is routinely dropped into the sea.
Enriching the 1%
It is worth asking where all that Mars money actually ends up.
Ultimately, the Mars program draws wealth from the public and puts it into the hands of the wealthiest people in society. The financial beneficiaries of this wealth are the well-off Western engineers and the huge transnational corporations (e.g. Lockheed Martin etc) that provide many of the services. Mars is the biggest money tree in history and many billionaires will be minted, funded by taxpayers money. This is occurring at a time when the gulf between the rich and the poor, both between and withing nations, is a major stress and risk in global security.
Mars will be dependent on Earth for centuries
It will take centuries, and hundreds of trillions of dollars, to make Mars self-sustaining.
These next few decades are crucial to life on Earth. Yet, at exactly the same time, there is now a huge drain on resources to help get humans to Mars. If people really want a sustainable Mars colony, they need to do that from a healthy planet Earth. So it's a paradox - on one hand the Marsophiles want to strip resources from Earth for their mission at the time when the Earth needs them most, and on the other hand they are completely dependent on Earth for their survival. Martian Madness!
Mars will never be a model society
We will transport all of our petty grievances to Mars.
Recently, a US Senator stated that he was opposed to funding any space program that included gay astronauts. Clearly, his prejudices extended beyond the surface of the Earth and into space. There is an idea that somehow a Mars colony will not suffer the petty grievances that plague the humans on the home planet. What a ridiculous idea.
Mars Colonists will be sick all the time
Micro-gravity and misery will condemn Mars colonists to ill health.
Mars Colonists will be permanently sick due to lack of direct sunlight, poor food, radiation and misery. What's more, wanting to go to Mars ought actually be defined as a mental illness, which is to say that you'd be sick before you even left Earth. You have to be sick to go to Mars. Also, the portable lavatory sized boxes called habitation modules will be excellent breeding ground for air-borne transmissible disease like Covid-19. The Mars colonists will die of COVID after having bled Earth of resources.
