why we should not send humans to mars
Rep. Kendra Horn (D-Okla.), chairwoman of the House space subcommittee, did mention in it in prepared remarks for an April 2 hearing by the full House Science Committee on the NASA budget request. Spacecraft at L2 can easily maintain a stable orbit, avoiding the slow drift that gravitational tugs from the sun and moon produce elsewhere. An astronaut expedition to repair one of these great observatories at L2 would involve at least as much complexity as a landing on the moon—and possibly a greater expense than the creation and launch of a new and improved observational platform. That total includes $29.2 billion for the DST, a figure that the report acknowledges is a very rough estimate given the few details about the design that could be used to project its development cost. India, which crashed a lander on the moon in 2019, dreams of doing likewise. Uplifting the human spirit. Why should we go to mars? It would increase dramatically the risk of forward contamination of the Mars surface with our earthly microbes, which would ruin our unique chance to study a pristine Mars. And the Japanese Hayabusa2 spacecraft will soon pass by Earth to release a capsule with material from the asteroid Ryugu, one of the oldest members of the solar system. We're putting so much money into going to mars, We don't even know if it will be successful. The fundamental issue of sending humans into the cosmos asks not how easily astronauts can repair instruments in deep space, how quickly they can land on the moon and construct a base there, or why they should travel to Mars and attempt to create a habitat there. A Dutch nonprofit venture called Mars One aspires to send four people to Mars by 2026 as the beginning of a permanent human settlement. You would agree that the center of Antarctica in winter is cold, not the best of places to set up … Many view the safety risks of putting humans on Mars as tolerable, so long as the astronauts give informed consent to be exposed to such risks. But these missions elevated our spirits, whereas writing off the telescope would have been a profound downer—a reminder that public opinion, which would have scorned the latter action while celebrating the former, understandably plays a crucial role in determining what our government chooses to do. Under that ideology, humans would never leave the Earth, and we would still be sitting here at the bottom of the gravity well when the “killer asteroid” finally hits us. By releasing sufficiently large amounts of carbon dioxide that currently reside in rocks and in Mars’s modest polar caps, along with other gases even better at trapping heat, we could produce a “greenhouse effect” that would raise the planet’s surface temperature and increase its atmospheric pressure to the point that liquid water could once again flow over the Martian surface. A mission to Mars launching in 2033, the report concluded, would need to have critical technologies tested by 2022, which is unlikely. This is a good thing. The Trump administration proposes to create a lunar base as a key step in sending astronauts to Mars. The exploitation of raw materials in space offers a wide range of construction, destruction and confrontation among private parties and corporations. In addition, plans to leave behind eight billion of their fellow humans on a dying planet might produce unrest sufficient to derail the project. And a poor use of a great deal of money. Last year, the 50th anniversary of the first moon landing found a host of private and governmental projects that aim to send astronauts far beyond the near-Earth orbits that have limited human space exploration since 1972. On Earth, helium-3 nuclei furnish only about one one-millionth of already scarce helium nuclei, but their relative abundance in lunar soil rises 100 times higher. By the time Obama was sworn in, the Constellation Program was behind schedule and over budget. Elon Musk wants to go to Mars. Why, then, should we not expect future astronauts, if called upon, to repair one of the numerous space-borne instruments to be sent to L2? Many spacecraft have died trying to get to Mars. They would carry with them their earthly microbes. ... Mars Over the Moon. In particular, space radiation—especially galactic cosmic rays (GCRs)—is dangerous. Ok we're onto the second reason why we should not go to Mars. “I’m okay with that because I think it accelerates the effort to get to Mars,” he said of the 2024 goal of a human return to the moon, “which I think is the underlying driving force here.”, SpaceX wins contracts for lunar lander, environmental satellite launches, Next-generation Dragon cargo spacecraft returns from space station, Aerojet Rocketdyne completes assembly of its first AR1 rocket engine, OneWeb slashes size of future satellite constellation. Wherever we land, we inevitably leave behind traces of our own forms of life. If these parties choose to act, who can stop them? The report, while completed prior to the March 26 speech where Vice President Mike Pence directed NASA to return humans to the moon by 2024, does offer insights into how much a lunar return might cost and how it fits into long-term plans to send humans to Mars. Since the first moon landing, we have sent several hundred probes throughout the solar system, from innermost Mercury to Arrokoth (previously nicknamed “Ultima Thule”), a planetesimal orbiting far beyond Pluto. “As such,” the report concludes, “a mission to Mars orbit in 2033 is infeasible from a technology development and schedule perspective.” The next launch window, in 2035, was also deemed infeasible because of technology development work, pushing the earliest possible date for flying the mission to the following launch window in 2037. These explorers will deploy numerous tools to probe rocks and minerals, using a memory equal—and soon superior—to any human’s. Human history shows that no scarcity of volunteers will arrive, including those who would gladly gain fame from being among the first to land, for example, on Mars, without any prospect of a return journey. Even the moon or asteroids, hostile to life though they now are, may contain traces of past biological activity. Ok we're onto the second reason why we should not go to Mars. Subscribers get more award-winning coverage of advances in science & technology. What benefits will flow from these efforts to send humans much farther into space? Space travelers will long resemble stunt motorcyclist Evel Knievel more than they do Jules Verne’s fictional adventurer Phileas Fogg. For these reasons and more, sending humans for long-duration missions to Mars would be unwise. To their enthusiasts, giant space colonies and human habitats on Mars offer not only sites to develop a better society but also places where we may modify humans … Mankind seems destined to one day set foot on Mars. Many view the safety risks of putting humans on Mars as tolerable, so long as the astronauts give informed consent to be exposed to such risks. All the Reasons Why Humans Shouldn’t Colonize Mars, According to Experts. Sending humans into space adds glory to our lives. Four major motivations deserve special attention as answers to this question. Space is a very hazardous place for humans. But sending people to Mars for long periods of time would be extremely unsafe, and we shouldn’t do it. But to many scientists, and to some among the public, such potent reactions fail to justify the costs and dangers of these missions. NASA’s Opportunity rover, for example, spent more than 15 years on Mars and traversed complex topography for more than two dozen miles, at a price tag that is almost certainly less than 1 percent of what a comparable human expedition would cost today. What future lies ahead for humans in space? We can imagine future space missions that use the more abundant minerals for the construction of mining colonies but that draw the bulk of their profits from the return of the most valuable metals to Earth. “Moreover, the report acknowledges what many on this Committee have been surmising during past hearings — namely, that there is no actual Plan for a human Mars mission.”, While NASA has, since Pence’s speech, focused on how it will develop an architecture for a 2024 moon landing, it has not neglected Mars entirely. If we create human colonies in space, their inhabitants might undergo evolutionary changes that make them more fit for space travel. Debating the wisdom of sending humans into space inevitably returns to the immense boost that humanity will receive from tracking astronauts as they explore other worlds. Almost everyone naturally responds to heroic accomplishments, and many of us would regard a human landing on Mars as a paramount achievement of our species. Some scenarios see humans heading to the Red Planet within a few years, while others foresee Mars missions by the 2030s. Do we want to regulate space adventuring—and if so, how? Such future plans appeal to those who see Earth’s future as deeply uncertain or even hopeless. A metal-rich asteroid that is only the size of a house would contain a million pounds of metal, including 100 pounds of platinum, gold and other rare metals. Automated spacecraft cost far less; they’re getting more capable every year; and if they fail, nobody dies. It's always a concern when sending surface probes to pristine worlds such as Mars that... 2. Cold. We should take this giant scientific leap only when we are ready, and we shouldn’t subject our brave astronauts—and the success of the missions—to undue risk. The James Webb Space Telescope, scheduled to supplant the now creaky Hubble next year, will be directed to the much more astronomically favored “L2 point” (for second Lagrange point), a million miles from Earth. Raw materials and the transformation of planetary surfaces. All the reasons advanced to vindicate the act of Humans traveling to Mars are either wrong or … And their loss, when it occurs, casts a pall over our would-be joy of identifying with their exploration. Meeting Aliens: Why We Must Not Send Humans to Mars Life may exist on Mars. That work, the STPI report concluded, will take too long to complete in time to support a 2033 mission. An artist's concept of what a Mission to Mars might look like. Instead, STPI used the cost of developing Orion as a proxy for the DST.

He also argued that going to the moon in 2024 would allow an earlier human mission to Mars. National pride. He says Nasa shouldn't be aiming to send manned missions to Mars And as complex, foreign organisms with a storied history of indelicate exploration in new environments, we humans might have more in store for Mars than it is prepared to handle too. There remains the pride that a nation may feel from sending the first humans to other worlds, as when President Donald Trump exalts a future “when American astronauts will plant our beautiful Stars and Stripes on the surface of Mars,” adding the pride of ownership to the thrill of human achievement. “Why do we go to the moon? The moon is a big piece of that.”. Aside from the immense difficulties of creating sustainable, million-person colonies (required for sufficient long-term genetic variation), any lunar or planetary colonists will bring the same human attributes that have caused problems on Earth. For colonies on Mars—even “harmless” ones whose purpose is purely exploration—the problem increases steeply: Most experts agree that life probably existed on Mars when water ran freely over its surface and may that it may yet survive in underground pools. If, as is likely to happen soon, we can manipulate the human genome as we like, we could manufacture a new set of beings designed for space travel.
