Terraforming 101: How to Make Mars a Habitable Planet

Terraforming 101: How to Make Mars a Habitable Planet

Before we can journey to the stars, we must first go to Mars.

That’s Elon Musk’s philosophy, anyways – and just days ago he revealed new details on his ambitions to colonize the Red Planet, including sending two cargo rockets by 2022 and four rockets (two manned, two cargo) by 2024.

In 40 to 100 years, Musk suggested that up to a million people could live there.

Change of Seasons

As Elton John wisely noted, “Mars ain’t the kind of place to raise your kids”.

Indeed, the average temperature on Mars is −55 °C (−67 °F), dust storms are frequent and potentially deadly, and the planet has extremely low atmospheric pressure (about 1% of Earth). Because of the atmosphere and temperature swings, meaningful occurrences of liquid water on the planet’s surface are almost impossible. And while Mars is thought to have plenty of frozen water at its poles and in underground deposits, the logistics of tapping into these resources could be quite difficult.

In other words, for any meaningful and long-lasting human presence on Mars, we would likely want to alter the planet and its atmosphere to make it more habitable for human life. And while the exact mechanisms we would use to accomplish this are still up for debate, the basics behind what’s needed to achieve Earth-like conditions are actually pretty straightforward.

Terraforming 101

Today’s infographic comes to us from Futurism, and it details what might need to happen on Mars to make it more accommodating to human life.

Here are two steps we could take to get Mars into the “Goldilocks Zone”, where water is liquid – and harmful ionizing radiation like x-rays, UV rays, and gamma rays are not problematic.

Greenhouse Gases
One way to ward off harmful ionizing radiation is to add a thicker layer of greenhouse gases to the atmosphere of Mars. Such an atmosphere would also allows less heat to escape, meaning warmer temperatures on the planet.

Magnetic Field
A strong magnetic field on Earth is something else that makes life easier. Earth’s solid inner core, composed primarily of iron, creates this field when the planet spins – and it deflects cosmic rays and other harmful types of radiation.

One interesting solution to solve this problem on Mars would to have a magnetic field generator in front of the planet at all times, deflecting any such rays coming from the sun.

The Realm of Possibility

While terraforming is still a mixture of theory and science fiction at this point, we do know some of the major problems that have to be solved for attaining a habitable environment – and it will be interesting to see how plans around Mars develop as the prospect of colonization becomes more real.

You need to live in a dome initially but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on. … So it’s a fixer-upper of a planet.

– Elon Musk

3D Map: The U.S. Cities With the Highest Economic Output

The total U.S. GDP stands at a whopping $21 trillion, but which metro areas contribute to the most in terms of economic output?

3D Map: The U.S. Cities With the Highest Economic Output

At over $21 trillion, the U.S. holds the title of the world’s largest economy—accounting for almost a quarter of the global GDP total. However, the fact is that a few select cities are responsible for a large share of the country’s total economic output.

This unique 3D map from HowMuch puts into perspective the city corridors which contribute the most to the American economy at large.

Top 10 Metros by Economic Output

The visualization pulls the latest data from the U.S. Bureau of Economic Analysis (BEA, 2018), and ranks the top 10 metro area economies in the country.

One thing is immediately clear—the New York metro area dwarfs all other metro area by a large margin. This cluster, which includes Newark and Jersey City, is bigger than the metro areas surrounding Los Angeles and Chicago combined.

RankMetro AreaState codesGDP (2018)
#1New York-Newark-Jersey CityNY-NJ-PA $1.77T
#2Los Angeles-Long Beach-AnaheimCA$1.05T
#3Chicago-Naperville-ElginIL-IN-WI$0.69T
#4San Francisco-Oakland-BerkeleyCA$0.55T
#5Washington-Arlington-AlexandriaDC-VA-MD-WV$0.54T
#6Dallas-Fort Worth-ArlingtonTX$0.51T
#7Houston-The Woodlands-Sugar LandTX$0.48T
#8Boston-Cambridge-NewtonMA-NH$0.46T
#9Philadelphia-Camden-Wilmington PA-NJ-DE-MD$0.44T
#10Atlanta-Sandy Springs-AlpharettaGA$0.40T
Total GDP$6.90T

Coming in fourth place is San Francisco on the West Coast, with $549 billion in total economic output each year. Meanwhile in the South, the Dallas metroplex brings in $478 billion, placing it sixth in the ranks.

It’s worth noting that using individual metro areas is one way to view things, but geographers also think of urban life in broader terms as well. Given the proximity of cities in the Northeast, places like Boston, NYC, and Washington, D.C. are sometimes grouped into a single megaregion. When viewed this way, the corridor is actually the world’s largest in economic terms.

U.S. States: Sum of Its Parts

Zooming out beyond just these massive cities demonstrates the combined might of the U.S. in another unique way. Tallying all the urban and rural areas, every state economy can be compared to the size of entire countries.

US States and Country Comparison by GDP 2018

According to the American Enterprise Institute, the state of California brings in a GDP that rivals the United Kingdom in its entirety.

By this same measure, Texas competes with Canada in terms of pure economic output, despite a total land area that’s 15 times less that of the Great White North.

With COVID-19 continuing to impact parts of the global economy disproportionately, how will these kinds of economic comparisons hold up in the future?

29 Psychological Tricks To Make You Buy More

This graphic looks at 29 different psychological tricks that marketers use to try and influence consumer behavior.

29 Psychological Tricks To Make You Buy More

Ever suffered from buyer’s remorse? You’re not alone.

According to a recent survey, only 5% of people have never felt guilty about buying something. That means the majority of us, at some point in our lives, have regretted a purchase.

But consumers aren’t necessarily only to blame for impulse buys. After all, we’re constantly bombarded with advertisements and marketing tactics specifically tailored to try and get us to spend more money.

Today’s graphic by TitleMax explains 29 different psychological tactics that marketers try to get consumers to buy more.

Tricks are for Marketers

While this list isn’t exhaustive, it provides some key examples of the ways that marketers are attempting to influence your subconscious mind.

We noticed some high-level trends among the 29 tactics, which we compiled into four overarching sections:

  • Visual Pricing Tricks
    These tricks aim to intentionally minimize the appearance of the price, so it’s more palatable to consumers. For instance, a store will price something at $9.99 instead of $10.00, or label a product as “buy-one-get-one” rather than 50% off.
  • Intentional Language Tricks
    It’s not what you say, but how you say it. Making products seem costly to manufacture, offering exclusivity, and using words associated with small amounts fall under this category. These tricks use semantics to position a product in an appealing way.
  • Brick-and-Mortar Tricks
    A store’s layout is less arbitrary than you may realize. Having a bright and colorful entrance, playing calm and slow music, and putting the essential items at the back of the store are a few tactics that fall into this section. These tricks use displays and product placement to influence consumer behavior.
  • Urgency Tricks
    A false sense of urgency and phase-out discounts are included in this category. If a consumer believes they might miss out on a deal, they’re more likely to buy.

The Theories in Practice

While most retailers are guilty of using at least a few of these tactics, several big companies are notorious for their use of psychological tricks to boost sales.

For instance, Ikea is well known for its confusing, maze-like layout. This is no accident, as an Ikea store’s architecture is designed specifically to maximize product exposure—it’s mastered what’s called the Gruen effect, a term named after architect Victor Gruen, whose elaborate displays were proven to convert browsers into buyers.

Another example is Walmart’s rollback pricing, which uses visual contrast to make the sale price more appealing. It’s clearly served the company well—in 2019, Walmart made $524 billion in revenue, making it the world’s largest retailer.

Costco uses a few tactics on the list, but one it’s notorious for is putting fresh produce in the back of the store. That means customers need to pass through the electronics, clothing, and household goods sections before they can get to the necessities.

While the above tactics are in a gray area, other tricks are flat out dishonest. Makeup brand Sunday Riley was caught writing fake Sephora reviews to boost sales. Employees were encouraged to write outstanding reviews for the company, and the CEO even provided instructions on how to avoid getting caught.

The Influencer Era

As consumers become aware of certain marketing tactics, retailers are forced to switch up their game in order to remain effective.

A relatively recent phenomenon is influencer marketing, which is when brands partner with vloggers or influencers to endorse a product. And these partnerships tend to work—a recent survey revealed that 40% of people have purchased something based on an influencer’s recommendation.

But how long will influencer marketing—or any of these tactics—stay effective? Some of the more subtle pricing tactics might stay relevant for longer, but it’s unlikely that all of these tricks will stand the test of time.
