A High Level Look at Satellites

View the full-size version of the first visualization to see in full detail.

Satellites rarely get much attention, but they’re the hubs that keep our modern world connected. Just how many satellites are orbiting around Earth? Who’s launching them? And, what exactly are they doing up there anyway? These are good questions. Let’s dig in.

Today’s visualization comes to us from Carey Spies, and while it is based on older data, it provides a useful breakdown of the types of satellites that orbit the Earth.

There are now nearly 1,500 satellites in orbit in 2017, and if SpaceX’s plans for a 4,425-satellite communications network come to fruition, our planet’s exosphere will become even more crowded.

What do satellites actually do?

Satellites are launched into space for a number of reasons.

They do everything from military reconnaissance to keeping our GPS systems working properly. The truly global scope of telecommunications wouldn’t be possible without our expansive network of orbiting satellites. For example, O3b Networks’ 12 satellites provide broadband internet service to emerging markets.

Types of Satellites

Who’s launching satellites?

The United States, with nearly 600 operating satellites, has clearly won the space race in this sense. That said, everyone from Azerbaijan to Vietnam now has equipment in orbit, and the list keeps growing.

The change over time, seen in this interactive map, shows that now practically everyone is in the game:

Launching rockets used to be the sole domain of nations, but the privatization of spaceflight has dramatically increased the number of commercial satellites in orbit. Iridium Communications, for example, has a constellation of 70+ operational satellites.

Anxiety in the Exosphere

Operating satellites are only one part of the equation. Sputnik I was launched into space nearly 60 years ago, and as one might guess, a lot of obsolete and dead equipment has built up over that time. The United States Space Surveillance Network estimates that there are 21,000 objects larger than 10cm orbiting the Earth. An increase in “space junk” could have major implications, as even tiny objects can cause severe damage to equipment.

We must cooperate now to guarantee economically vital spaceflight.

– Brigitte Zypries, German Federal Minister for Economic Affairs and Energy

Another looming issue is the potential weaponization of space. Until now, nations have operated under the “gentlemen’s agreement” that nothing launched into space should be weaponized, but the U.S., China, and Russia have all been accused of taking steps towards putting destructive objects into orbit. Beyond the obvious implications of conflict in space, damaged satellites would also exacerbate the aforementioned “space junk” problem.

What’s on the Horizon

While companies like SpaceX are looking for ways to reduce the overall cost of launching rockets into space, other innovations may also make it easier than ever to put structures into orbit. The Archinaut Program – which received $20 million in funding from NASA – is looking at ways to manufacture and assemble structures in space.

One thing is for certain; space is about to get a whole lot more crowded.

The world’s 20 biggest tech companies are worth over $20 trillion in total. To put this in perspective, this is nearly 18% of the stock market value globally.

A Closer Look at The Top 20

Market capitalization (market cap) measures what a company is worth by taking the current share price and multiplying it by the number of shares outstanding. Here are the biggest tech companies according to their market cap on June 13, 2024.

Apple is the largest tech company at the moment, having competed with Microsoft for the top of the leaderboard for many years. The company saw its market cap soar after announcing its generative AI, Apple Intelligence. Analysts believe people will upgrade their devices over the next few years, since the new features are only available on the iPhone 15 Pro or newer.

Microsoft is in second place in the rankings, partly thanks to enthusiasm for its AI software which is already generating revenue. Rising profits also contributed to the company’s value. For the quarter ended March 31, 2024, Microsoft increased its net income by 20% compared to the same quarter last year.

Nvidia follows closely behind with the third-highest market cap, rising more than eight times higher compared to its value at the start of 2023. The company has recently announced higher profits, introduced a higher dividend, and reported that its next-generation GPU chip will start generating revenue later this year.

AI a Driver of the Biggest Tech Companies

It’s clear from the biggest tech companies that involvement in AI can contribute to investor confidence.

Among S&P 500 companies, AI has certainly become a focus topic. In fact, 199 companies cited the term “AI” during their first quarter earnings calls, the highest on record. The companies who mentioned AI the most were Meta (95 times), Nvidia (86 times), and Microsoft (74 times).
