It's Time for Us to Become a Spacefaring Species
Establishing a colony on Mars would protect the long-term survival of the human race.
Stephen Petranek’s career of over 40 years in the publishing world is marked by numerous prizes and awards for excellent writing on science, nature, technology, politics, economics and more. He has been editor-in-chief of The Miami Herald’s prestigious Sunday magazine, Tropic, as well covering a wide range of topics for Time Inc.’s Life magazine. His presentation, 10 Ways the World Could End, is one of the most original and most watched TED talks of all time. He is now the editor of Breakthrough Technology Alert, for which he finds the investment opportunities that create true value and move the human race forward. His new book is titled How We'll Live on Mars.
Stephen Petranek: The reason we need to travel to Mars and to establish a civilization on Mars is to protect the long-term survival of the human species. We need to become a spacefaring society and eventually we need to move far beyond Mars — not only from our own solar system, but into other solar systems within this galaxy and other solar systems in other galaxies. We are making wonderful progress finding other Earth-like planets and we will continue to find many of those in the future.
Eventually the human species is going to disappear. That means everyone who’s a human being will die eventually and this species will die out and go extinct. And there are a number of reasons how that could happen and why that could happen including a large asteroid hits Earth and destroys everything larger than a rabbit as happened in the age of the dinosaurs 65 million years ago or eventually our sun begins to die and that is a 100 percent probability our sun will begin to die in about 2 billion years. And one of two things will happen. Either Earth will be thrown completely out of its orbit and go spinning off into space and everyone will die very quickly. Or the sun will essentially irradiate Earth as it expands because what happens with a dying sun is it gets very large. And so in order to survive as a species we have to become a spacefaring species. We have to get off this planet eventually and that is the long-term hope for humanity.
Mars is the most habitable place in our solar system by far. And even though it’s an incredibly hostile environment, we’ve developed the technology over the last 50 years to survive on Mars and to survive quite readily. So Mars is a wonderful first step. It’s where we go to learn how to go farther. Elon Musk says he will land on Mars in 2025. We’ve had, he and I have had a number of — several conversations about this. He’s more optimistic than I am and he’s one of the most optimistic people I’ve ever met. I’m very optimistic, but he’s more optimistic than I am. So I am in the discussion with him about a timeframe and when a SpaceX rocket or two might land on Mars. We kind of came to the conclusion that maybe we should say 2027. In other words, give him a two-year fallback. But he specifically says and I quote him on this in the book that he will be extremely disappointed if a SpaceX rocket has not landed on Mars by 2030. And I think that’s quite reasonable. I’d give 90 percent odds to a betting person that a SpaceX rocket will land on Mars before 2030.
Establishing a colony on Mars would protect the long-term survival of the human race. At some point, we're going to need to become a spacefaring species. There's no better time than now to get started.
Stephen Petranek is a journalist and author of a new book titled How We'll Live on Mars. Fittingly, he's here to tell us not just how we'll live on Mars, but also why and when. The why? As mentioned, we need to get off this rock sooner or later. The when? Within 15 years.

Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.
- The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
- Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
- Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.
Bacteria under microscope
needpix.com<p>Today, bubonic plague can be treated effectively with antibiotics.</p><p style="margin-left: 20px;">"Unlike in the 14th century, we now have an understanding of how this disease is transmitted," Dr. Shanthi Kappagoda, an infectious disease physician at Stanford Health Care, told <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">Healthline</a>. "We know how to prevent it — avoid handling sick or dead animals in areas where there is transmission. We are also able to treat patients who are infected with effective antibiotics, and can give antibiotics to people who may have been exposed to the bacteria [and] prevent them [from] getting sick."</p>
This plague patient is displaying a swollen, ruptured inguinal lymph node, or buboe.
Centers for Disease Control and Prevention<p>Still, hundreds of people develop bubonic plague every year. In the U.S., a handful of cases occur annually, particularly in New Mexico, Arizona and Colorado, <a href="https://www.cdc.gov/plague/faq/index.html" target="_blank">where habitats allow the bacteria to spread more easily among wild rodent populations</a>. But these cases are very rare, mainly because you need to be in close contact with rodents in order to get infected. And though plague can spread from human to human, this <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">only occurs with pneumonic plague</a>, and transmission is also rare.</p>
A new swine flu in China<p>Last week, researchers in China also reported another public health concern: a new virus that has "all the essential hallmarks" of a pandemic virus.<br></p><p>In a paper published in the <a href="https://www.pnas.org/content/early/2020/06/23/1921186117" target="_blank">Proceedings of the National Academy of Sciences</a>, researchers say the virus was discovered in pigs in China, and it descended from the H1N1 virus, commonly called "swine flu." That virus was able to transmit from human to human, and it killed an estimated 151,700 to 575,400 people worldwide from 2009 to 2010, according to the Centers for Disease Control and Prevention.</p>There's no evidence showing that the new virus can spread from person to person. But the researchers did find that 10 percent of swine workers had been infected by the virus, called G4 reassortant EA H1N1. This level of infectivity raises concerns, because it "greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses," the researchers wrote.
The word "learning" opens up space for more people, places, and ideas.
- The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
- Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
- Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.

Every summer, children on the Alaskan island of St Paul cool down in Lake Hill, a crater lake in an extinct volcano – unaware of the mysteries that lie beneath.
The coronavirus pandemic has brought out the perception of selfishness among many.
- Selfish behavior has been analyzed by philosophers and psychologists for centuries.
- New research shows people may be wired for altruistic behavior and get more benefits from it.
- Times of crisis tend to increase self-centered acts.
