Elon Musk's SpaceX approved to launch 7,518 Starlink satellites into orbit
SpaceX plans to launch about 12,000 internet-providing satellites into orbit over the next six years.
- SpaceX plans to launch 1,600 satellites over the next few years, and to complete its full network over the next six.
- Blanketing the globe with wireless internet-providing satellites could have big implications for financial institutions and people in rural areas.
- Some are concerned about the proliferation of space debris in Earth's orbit.
The Federal Communications Commissions has approved the last key request of SpaceX's plan to provide the globe with wireless internet beamed from thousands of satellites, a project known as Starlink.
On Thursday, the FCC said the private aerospace company can launch an additional 7,518 satellites into orbit, bringing the total number of approved satellites to about 12,000. The commission first approved the launch of 4,400 Starlink satellites in March following the company's successful deployment of two test satellites. SpaceX plans to launch the first 1,600 satellites within the next few years, and to launch a full network of internet-providing satellites over the next six.
SpaceX CEO Elon Musk said the goal is to create a new kind of global communications system.
"This is quite an ambitious effort," Musk said in 2016. "We're really talking about something which is, in the long term, like rebuilding the internet in space."
Low Earth orbit
Internet-providing satellites have been around for years, as I wrote in an article on the Starlink project from April. However, they're typically expensive and provide slower service than land-based internet infrastructure. This is mainly because it takes a relatively long time for a signal to travel from the satellite to the host. SpaceX plans to solve this problem by launching satellites into low Earth orbit–just hundreds of miles up, in order to reduce the "latency," or time it takes for the signal to travel.
However, the problem with this low-orbit solution is that it reduces the amount of surface area to which each satellite is able to provide service. That means SpaceX will need lots of satellites if it wants to cover the globe with wireless service. To accomplish this, SpaceX plans to launch about one-third of its 12,000 satellites into low Earth orbit, about 680 miles above ground, and the remainder into very-low Earth orbit, about 210 miles up. The satellites would communicate in a peer-to-peer system, using a combination of lasers and radio waves.
The implications of a faster connection
In addition to providing internet access to rural areas and other places where infrastructure is lacking, one institution stands to gain tremendously from the Starlink network: banks.
In the financial practice known as high-frequency trading, shaving mere microseconds off of latency can give traders an extraordinarily lucrative advantage in the market. Financial institutions would likely shell out billions for dedicated service, which would help SpaceX maintain its costly constellation of satellites.
The dangers of space debris
Some are concerned about the proliferation of space debris in Earth's orbit, including NASA administrator Jim Bridenstine.

The U.S. military already tracks more than 500,000 pieces of space junk flying around the planet at lethal speeds.
"My favorite example is an innocuous little screwdriver that slipped through an astronaut's grasp and has been circling low Earth orbit at up to 21,600 miles per hour for the last 35 years," said FCC Commissioner Jessica Rosenworcel. "At these speeds, even a common household item can wreak havoc."
On Thursday, the FCC published a proposal designed to limit the amount of space debris brought into orbit by the satellite industry. The commission also signed off on plans for three other companies to launch internet-providing satellites into orbit: Kepler, Telesat and Leosat, all of which are competing with SpaceX to build the world's dominant satellite internet network.

Coronavirus layoffs are a glimpse into our automated future. We need to build better education opportunities now so Americans can find work in the economy of tomorrow.
- Outplacement is an underperforming $5 billion dollar industry. A new non-profit coalition by SkillUp intends to disrupt it.
- More and more Americans will be laid off in years to come due to automation. Those people need to reorient their career paths and reskill in a way that protects their long-term livelihood.
- SkillUp brings together technology and service providers, education and training providers, hiring employers, worker outreach, and philanthropies to help people land in-demand jobs in high-growth industries.

Do we really know what we want in a romantic partner? If so, do our desires actually mean we match up with people who suit them?
- Two separate scientific studies suggest that our "ideals" don't really match what we look for in a romantic partner.
- Results of studies like these can change the way we date, especially in the online world.
- "You say you want these three attributes and you like the people who possess these attributes. But the story doesn't end there," says Paul Eastwick, co-author of the study and professor in the UC Davis Department of Psychology.
Do we really know what we want in love or are we just guessing?<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="204859156383d358652fda6f7eadda0f"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/vQgfx2iYlso?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>More than 700 participants selected their top three qualities in a romantic partner (things like funny, attractive, inquisitive, kind, etc). They then reported their romantic desire for a series of people they knew personally. Some were blind date partners, others were romantic partners and some were simply platonic friends.</p><p>While participants did experience more romantic desire to the extent that these personal connections of theirs (people they knew) had the qualities they listed, there was more to the study. </p><p>Paul Eastwick, co-author and professor in the UC Davis Department of Psychology <a href="https://medicalxpress.com/news/2020-07-romantic-partner-random-stranger.html" target="_blank">explains</a>: "You say you want these three attributes and you like the people who possess these attributes. But the story doesn't end there." </p><p>The participants also considered the extent to which their personal acquaintances possessed three attributes nominated by some other random person in the study. For example, if Kris listed "down-to-earth", intelligent and thoughtful as her own top three attributes, Vanessa also experienced more desire for people with those specific traits. </p>

What we claim to want and what we look for may be two separate things...
Image by GoodStudio on Shutterstock<p>So the question became: are we really listing what we want in an ideal partner or are we just listing vague qualities that people typically consider as positive?</p><p>"So in the end, we want partners who have positive qualities," Sparks explained, "but the qualities you specifically list do not actually have special predictive power for you." </p><p>In other words, the idea that we find certain things attractive in a person does not mean we actively seek out people who have those qualities, despite saying it's what we want in a love interest. The authors of this study suggest these findings could have implications for the way we approach online dating in the digital age. </p><p>This isn't the first study of its kind to suggest that what we find in love isn't really what we were looking for. The evidence suggests that we really are consistent in the abstract of it all: when asked to evaluate what you want on paper, you are more likely to suggest overall attractiveness in accordance with what you've stated are important ideals to you. But real life isn't so similar. </p><p>According to <a href="https://www.psychologytoday.com/us/blog/meet-catch-and-keep/201506/when-it-comes-love-do-you-really-know-what-you-want" target="_blank">Psychology Today,</a> who covered a 2015 study with similar results, initial face-to-face encounters have very little effect on our romantic desire. "When we initially meet someone, our level of romantic interest in the person is independent of our standards."</p><p>While you might have no immediate interest in John, he may fit your criteria of being kind, loyal, and intelligent. Similarly, someone may be attracted to Elaine even though she doesn't have any of the qualities they originally said were important to them. </p><p><strong>What does this all mean? </strong></p><p>The authors of both the 2015 and 2020 studies say the same thing: give someone a chance before writing them off as a poor match. If your initial attraction is independent of the standards you've set out, the qualities which you've listed as important to you, the first time you meet someone may not give you enough information to make an informed decision.</p><p>"It's really easy to spend time hunting around online for someone who seems to match your ideals," said Sparks, "But our research suggests an alternative approach: Don't be too picky ahead of time about whether a partner matches your ideals on paper. Or, even better, let your friends pick your dates for you." </p>
