There is no indication of life on Mercury. Temperatures during the day can reach 430 degrees Celsius (800 degrees Fahrenheit) while at night can dip to -180 degrees Celsius (-290 degrees Fahrenheit). Life (as we know it) is unlikely to exist on this planet.
However, there is evidence that points toward water having existed on Mercury in some form. The most conclusive piece of evidence comes from the MESSENGER spacecraft, which has been orbiting Mercury since 2011. The probe has found that the amount of water vapor in the atmosphere increases when the Sun is out and decreases when it's not. This indicates that there is water vapor in the atmosphere, but it is not present in sufficient quantities to support life as we know it.
In addition to MESSENGER, other missions have gone beyond just observing Mercury and have actually landed on its surface. These include the Mariner 10 mission in 1974 and 1975, which was the first ever close-up look at the planet from outside Earth's orbit.
Both men and machines have tried and failed over the years to survive on Mercury. No one has managed to do so yet because they only have data about how to operate vehicles within Earth's environment, which is different than what is experienced by humans or animals on other planets.
It is possible that one day humans might travel to Mercury and try to live their own version of a Martian existence.
Plants require consistent temperatures. Mercury's temperatures range from 400 degrees Celsius during the day to -200 degrees Celsius at night. Any vegetation, living or dead, on its surface would either freeze or catch fire. That's a resounding no.
But mercury is the first planet out of the eight major planets in our solar system that is not made of rock. It is a dense, metallic substance that is extremely hot due to its inner core of molten iron. The other seven planets include: Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
The only plant species known to survive on mercury are those that enter a deep sleep each night. A drop of water may as well be an ocean when placed within this environment!
Any other life form would be killed by the heat, heavy metals or radiation emitted by mercury. The moon, which orbits around mercury every 487 days, could destroy any exposed land areas through tidal flooding or erosion.
However, if a piece of mercury were to make it to earth, it would be very dangerous for humans and animals because even small amounts of these heavy metals can be toxic. The most effective way to remove harmful substances from the body is through urine and feces.
Mercury is uninhabitable because it lacks an atmosphere and has temperatures ranging from 212 to 1,292 degrees Fahrenheit (100 to 700 degrees Celsius). It is also highly toxic. Humans can survive on Mercury for a few days but then begin to suffer damage to their organs.
However, because Mercury has natural resources such as gold, silver, zinc, copper, and uranium it may be possible to live there in the future.
Now let's look at the Earth's other planets.
Earth is the only planet that supports life. It has an atmosphere, water, and temperature ranges where life could possibly exist. It is also the only one of the eight planets that can support life. Life on Earth began with the formation of the planet 4.5 billion years ago. Since then, many species have gone extinct while others have evolved into today's 7 billion people. The fact that life can exist on Earth shows that it is likely that there are other worlds out there where life can thrive. We just need to find them.
So, overall, Mercury is not livable because it is extremely hot and toxic. The Earth is the only place in our solar system where life can exist.
Mercury's dark side is that it is extremely cold since it has practically no atmosphere to hold in heat and keep the surface warm. Temperatures can fall below -300 degrees Fahrenheit. The bases of several craters near Mercury's poles are never illuminated by sunlight. These basaltic plains are probably frozen solid all year round.
But even though the Sun doesn't light up Mercury's face, it still manages to heat its body. The planet receives about 30 times more radiation from the Sun than does Earth. Most of this energy is reflected back out into space but some reaches the surface. Because mercury has no atmosphere to protect it, this heat source can cause big problems for any living thing that ends up there. Animals and humans would die if they were to be sent to Mercury without protection!
Colder than Earth? Yes, because hydrogen is the most abundant element in the Earth's atmosphere, having two atoms where ours have one makes Earth warmer. On Mercury, however, there is only 1/80th as much hydrogen so it gets cooled down quickly compared to Earth. The average temperature on Mercury is -240 degrees F which is considered ice-cold by human standards.
This planet was once like Earth with an iron core, a liquid metal shell, and an atmosphere. But due to tidal forces acting on its weak shell, mercury was stripped of most of its original mass over time.
Mercury is not an easy planet to thrive on, but it is not impossible. It's worth mentioning that without a space suit, you wouldn't last long owing to a lack of atmosphere. Furthermore, Mercury experiences one of the biggest temperature variations in the solar system. From -300 degrees Celsius at night to over 500 degrees during the day. This is why most spacecraft don't live longer than three months.
However, if you were able to survive the first few hours after landing, then you could live out your days aboard Mercury.
Your body would be exposed to high levels of mercury throughout life. This is because much of it gets locked up in the biosphere and does not decay. You would absorb mercury through your skin, lungs, and intestines. It would also be found in urine and feces since these are products of muscle contraction. The main way to remove mercury from your body is by urinating it out.
The concentration of mercury in soil varies depending on where you are on Earth. Areas with volcanic activity have higher levels of mercury in their soil due to the release of this element into the environment during explosions and lava flows. Areas that receive significant rainfall should avoid contaminated soil because it will wash off into local waterways.
In conclusion, living on Mercury is possible but difficult. Your health would suffer as a result of constant exposure to such high levels of mercury.
