Science behind the Shape of Bubbles and Why they Pop. Even delivering small machines requires larger, fuel-hungry rockets, so exchanging infrastructure to build entire colonies, at least currently, is impossible. The water could also be broken up into its constituent components to extract oxygen to breathe! The prospect of colonization seems far more feasible on a celestial body that is closer to our planet, so close that we feel and witness its gleaming presence every night. While it is possible that a self-sustaining colony could be designed and constructed sometime in the future, the technology does not currently exist to make a Martian colony feasible. It makes perfect sense to expand human presence to Mars, but we… I'm not saying that human spaceflight is too dangerous and that we shouldn't be sending humans into space at all. The Opportunity Rover also found copper, gold, zinc, tungsten and a variety of other elements. we respect your privacy and take protecting it seriously. But there are a few reasons we should continue to stay put, at least for a little while longer. Even more costly would be the constant trips to Mars to resupply the colony. How To Win Every Game Of Rock-Paper-Scissors. Another reason we should go to Mars, according to deGrasse Tyson, is to inspire the next generation of space explorers. Its gravity is one-third than gravity is on Earth, a slump in weight that will require its colonists some time to get accustomed to. Why Is Microsoft Planning To Move Data Centers Under Water? Subscribe to our mailing list and get interesting stuff and updates to your email inbox. Sheepshead Fish: Facts About The Fish With Human Teeth, Circle Of Willis: Anatomy, Diagram And Functions. On top of that, if you sneeze in space, all the droplets come straight out and keep going. Well, strictly speaking, you can’t. There is also no edible food and very little available water. How Does Nicotine Act As Both A Stimulant And A Depressant? Why live on Earth when you can live on Mars? We live in an age where we could go out and find other places to expand. On Mars, that means we could trigger a deliberate greenhouse gas effect that would melt the ice at the poles, release a load of CO2, make the atmosphere denser, and trap more heat and energy from the … After detecting hydrogen near the poles, the Lunar Prospector was programmed to deliberately nosedive into the south polar crater at the end of its mission in the hope that the surface, following the impact, would bleed profusely with water. The Martian atmosphere is 95-percent carbon dioxide. However, given the construction of an artificial environment, life on Mars could be possible. Pyramid-like structures have been discovered on Mars. These samples revealed that the moon’s geology is quite similar to Earth’s, suggesting that the moon could have been formed by the coalescence of a splintered chunk of Earth’s mass blown into space due to a catastrophic collision with another celestial body. It is no wonder that water is regarded as the most important substance in space. Is Aluminum Magnetic? Excellent article and worthy of discussion and serious thought. 'To successfully walk on the Martian surface unaided, humans would need to create an atmosphere similar in composition and thickness to that of Earth.' Mars is calling. Inhabiting Mars is more promising, because like our planet, it is engulfed and protected by an atmosphere. He says Nasa shouldn't be aiming to send manned missions to Mars Anders, 85, said he's a "big supporter" of the "remarkable" unmanned programmes, "mainly because they're much cheaper". 1. Mars seems to be a good alternative. Not to mention a significantly lower level of gravity. 6. Why Are Bathtubs Usually Shorter Than A Person’s Height? The Lunar Prospector and Clementine Probe hinted that the moon was home to an ocean of water, some billion metric tons, that was cold and solidified beneath the thick crust of dust and ice. The water can be consumed, mixed with food, and could even mediate sanitation. But colonies - just don't 'see it. How Big Is It and Does It Bite? We must find a new home. It is only 0.13-percent oxygen, far less than the 21 percent available on Earth. Furthermore, the roaring energy generated by the recombination of these elements could propel rockets. Nothing of the sort was observed. Mars is the closest thing we have to Earth in the entire solar system, and that’s not saying much. 6. Though robotic spacecraft can do a lot, they lack the critical intuition, lifetime experience, and decision-making skills that humans have. Buzz Aldrin salutes the first American flag erected on the Moon (Image Credit: Neil A. Armstrong / NASA). But there’s nothing we could do to earth’s atmosphere to make it as bad as Mars, which is both extremely thin and also 96% carbon dioxide. The search for life on Mars shouldn't focus exclusively on the distant past, some researchers say. Is Mount Everest Really The Tallest Mountain On Earth? We’re already killing our own planet. Furthermore, the cratered and craggy surface of the moon is thoroughly suffused by lunar dust. Even with all of that in mind, scientists are still uncertain about the presence of water on the moon. That same population is boiling the planet by burning coal and simultaneously suffocating it with the dense, grey smoke that combustion releases. Jun 14, 2016 NASA. What Is The Fibonacci Sequence? And hopefully, I won't have to jostle with tourists there. Does Burnt Toast Have The Same Amount Of Calories As Regular Toast? We’re not sure why, but it seems that bacteria are more dangerous in space. Mars’ gravity is less than Earth but large enough to lure gases and form an atmosphere. I suspect that AI and robotic development will reach the point that by the time we can send and return a few people to Mars, we can send indestructible “human-like” robots that can accomplish the same things (and more) on a Mars mission that a real human could do, but without the life-sustaining needs and fragility of humans. The History of the United States' Golden Presidential Dollars, How the COVID-19 Pandemic Has Changed Schools and Education in Lasting Ways. Compare that time to the protracted time colonists of the moon would require getting accustomed to its gravity, which is just one-sixth of gravity on Earth. On the other hand, we shouldn’t use this as an excuse to pollute the Earth, or let global warming run amok. Oxygen, by some miraculous technological feat, can also be extracted from regolith, which is 42% oxygen. This idea that we are going to abandon Earth and go live on Mars is utter nonsense. This assumes that Earth-like atmosphere and temperatures, as well as food and water, can be provided, but providing such an environment on Mars would be enormously expensive. The atmospheric layer would also protect us from the sun’s UV rays, without which we would be fried in seconds on the moon. Inhabiting Mars is more promising, because like our planet, it is engulfed and protected by an atmosphere. When the the first Apollo mission landed on the moon they only had 30 seconds of fuel left, 30 SECONDS! If we wanted to live there, we would have to wear a pressurised suit. This oxygen can then be inhaled and combined with hydrogen to form water and fuel. By Jay Bennett. I think settlements as in the Antarctic habitats for sure. We are there right now. Even though the benefits of terraforming the moon might outweigh its risks, scientists continue to dismiss it because, at the end of the day, it is a cold, harsh, barren and dangerous place to live. Or, colonists anxious about their jeopardized fashion could also take shelter in the moon’s deep caves, just as the first people on Earth inhabited its caves through the past millennia. Akash Peshin is an Electronic Engineer from the University of Mumbai, India and a science writer at ScienceABC. (Photo Credit: NASA). Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies, What Exactly is Archimedes Principle: Explained in Simple Words, What is Evolution? It’s illogical. Considering the travel costs and convenience, the moon seems to be the ideal place to settle economically. It gets warm at midday, briefly, can go over 0 °C. On the other hand, Mars’ core constitutes quite different elements. Earth’s resources are depleting at a frightening rate. The moon resides just 3 days away from us. A thick cloak of this dust may also protect the inhabitants from radiation. The Apollo missions conducted between 1969 and 1972 ferried around 840 pounds of moon rock and soil back to Earth. The fact is, we already have been to Mars. Mars is the closest thing we have to Earth in the entire solar system, and that’s not saying much. Despite these amenities, why do space explorers persist to favor Mars instead? However, given the construction of an artificial environment, life on Mars could be possible. Unless we radically adapt our brains and bodies to the harsh Martian environment, the Red Planet will forever remain off limits to humans. Why Are There Stones Along Railway Tracks? Rather than a blazing lunar noon, the poles experience more of a solemn sunset. CROSS-CONTAMINATION FROM EARTH It's always a concern when sending surface probes to pristine worlds such as Mars that Why Is It So Special? We have been operating rovers on the surface of Mars since 1997, and landed another one, Curiosity, in 2012. Enamored with science ever since discovering a picture book about Saturn at the age of 7, he believes that what fundamentally fuels this passion is his curiosity and appetite for wonder. Mars landers found trace amounts of vital minerals such as aluminum, titanium and iron. “It is really because we have an innate desire to explore.” What Is The Huntsman Spider? But what about the good reasons not to go to Mars? The fourth planet from the Sun, Mars is named after the Roman God of war. The more resources we can harness on the Red Planet, the fewer we need to bring with us. The atmosphere is also nearly 100 times thinner than Earth's, meaning Mars cannot retain the radiant heat of the sun, so while late afternoon at the Martian equator may be a comfortable 70 F, at night the temperature would fall to 100 F below zero. Bill Nye made remarks this week in an interview this week with USA Today. The planet is currently being ransacked for its resources by its skyrocketing population like a herd of children ambushing an ice cream truck. Mars has water, an atmosphere, and other resources that should allow us to live off the land. Everyone is always going on about the myriad of good reasons to send humans to Mars. I feel like I shouldn’t even have to explain this one but basically, we cannot breath on Mars without oxygen tanks and such and that terrifies me. Will we stick with robots or ship off the humans? However, like the overused plot of nearly every romantic comedy, the moon is believed to be hiding beneath its grey dust and craggy exterior, a heart filled with an ocean of hope. The abrasive powder clings to everything it acquaints. That reason is That we almost did not achieve the Moon manned missions. Since humans have lived in space for extended periods of time in ships or orbital station, it's reasonable to suppose that life on Mars is also possible. The most promising dwelling place seems to be the lunar poles, which are not only believed to rest upon large slabs of ice, but are also subject to comparatively calmer temperatures. In the second instalment of his two-part feature on human missions to Mars, Dr Alexander Kumar asks whether we should send people to the Red Planet given our poor record managing this one. Furthermore, two-way trips to our red neighbor are extremely strenuous. Well, mine is not an absolute "shouldn't". Exchanging infrastructure isn’t a big deal either; in fact, catapulting an object from the moon at a suitable angle would cause it to drop pleasantly into the hands of our planet. How Does the 25th Amendment Work — and When Should It Be Enacted. The Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. In the long run, however, Mars emerges as the clear winner. These failures could cause permanent damage to expensive exploration machinery and cost us entire missions, but more importantly, a life. Humanity has flown people into outer space and landed them on the moon. It’s important to explore Mars, and humans play a valuable role in that research. Why Are There Stones Alongside Railway Tracks? 1 To see pyramids in space. Known as regolith, the dust is fine enough to slip through narrow crevices and cause mechanical failures. So-called "blueberries" are structures that contain hematite, a type of ore that makes steel. “We are not going to go to the moon or Mars because of population pressure,” he explained. Humans cannot live on Mars because neither the temperature nor the atmosphere is compatible with human survival. But I think we probably won't want to once all the information is in, at least not in the near future. When it comes to colonizing outer space, Mars gets most of the attention, but there are also some very compelling reasons why we should colonize Titan. Even though its atmosphere doesn’t sustain pressurized oxygen like ours, which is imperative to live, it still protects the planet from the destructive shower of meteoroids, a phenomenon ubiquitous on the moon. Why Are Some Materials Magnetic? Humans cannot live on Mars because neither the temperature nor the atmosphere is compatible with human survival. Ok we're onto the second reason why we should not go to Mars. From: SMITHSONIAN SPOTLIGHT: Space: Bots or Bodies http://bit.ly/1yQwTje Fact Check: Is the COVID-19 Vaccine Safe? The poles are craggier than the other areas of the moon. The Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. What Are the Steps of Presidential Impeachment? Almost Everything We Need to Live on Mars Is Already There. Why Are There 52 Cards In A Deck, With 4 Suits Of 13 Cards Each? The Lunar Prospector and Clementine Probe hinted that the moon was home to an ocean of water, some billion metric tons, cold and solidified beneath the thick crust of dust and ice. What Would Happen If You Shot A Bullet On A Train? Carbon dioxide and other greenhouse gases would be vital to keep Mars warm enough. However, a journey to Mars takes months, and even that is dependent on its alignment with our planet. NASA astronaut Ed White during a spacewalk June 3, 1965. In fact, propellants fueled by the combination of hydrogen and oxygen are the most powerful propellants we’ve ever developed. These aspects could allow the contingencies of immediate retreat or summoning help to be more successful. Buzz Aldrin’s footprint on the lunar surface (Image Credit: Buzz Aldrin / NASA). The moon’s lack of an atmosphere is the result of its paltry mass and weak gravity. Mars is also subject to winds and seasons, whereas the temperatures on the moon can vacillate between 253 degrees Fahrenheit and -387 degrees Fahrenheit in a single day. Its distance exacerbates communication delays typically up to 4 minutes. The increase in the population further widens the social and financial cracks, allowing a stench of distrust to creep in. Greenhouse gases trap heat in the atmosphere. There is also no edible food and very little available water. What Does George Soros' Open Society Foundations Network Fund? But sending people to Mars for long periods of time would be extremely unsafe, and we shouldn’t do it. Here are a couple: 1. Why Don’t We Try To Colonize The Moon Instead Of Mars? The arguments above show that we are perhaps not ready to go to Mars – at least, not today. Saturn’s largest moon Titan is the only natural satellite with more than a trace atmosphere. due to a catastrophic collision with another celestial body. live on Mars. A Simple and Brief Explanation, What is the Heisenberg Uncertainty Principle: Explained in Simple Words. Why Is The Sun White At Noon And Red During Sunrise And Sunset. A few more reasons why we shouldn’t move to Mars include the facts that it’s too cold for us to survive without an abundance of extremely reliable technology, the atmosphere is so thin it counts as a laboratory vacuum on Earth, there are rough and global dust storms and much more, according to Scientist Robert Walker. The only reason the entire planet isn't covered in ice is because it has so little water to turn into ice, and as the atmosphere is a near vacuum, the ice sublimates into water vapour (like dry ice) and collects at the poles. I don’t entirely agree that Mars is the best place to do it, but we should at least have another party going on somewhere. The evidence gathered by the missions never materialized. We cannot breathe on Mars. 10. Another downside is that even if the poles did obscure water, landing on their surface poses an arduous challenge. The low levels of sunlight falling on them for prolonged periods maintain temperatures of up to 32 degrees Fahrenheit. Here are a few reasons why we might want to stop sending humans out into space for the foreseeable future: 1. Coefficient Of Restitution: Definition, Explanation And Formula. Lead: The Ancient (And Deadly) Artificial Sweetener. Elon Musk is a huge proponent of not merely exploring Mars, but terraforming it. In the case of a fatal emergency, abandoning a mission and retreating home or summoning help is just a forlorn attempt at rescuing. The moon, so devoted to its orbit around us, is only 3 days away, such that the communication delay is mere seconds. But, we won’t know if a permanent presence is possible until we try. Even though its atmosphere doesn’t sustain pressurized oxygen like ours, which is imperative to live, it still protects the planet from the destructive shower of meteoroids, a phenomenon ubiquitous on the moon.
