What Elon Musk's 42,000 Satellites Could Do To Earth
You're looking at 60 satellites hurtling into the sky. And over the next few decades, Elon Musk is hoping to send 42,000 of these satellites to space, 15 times the number of operational satellites in orbit today. It's part of Starlink, the expansive constellation
from Musk and SpaceX that hopes to bring the world low-latency high-speed internet, promising no more buffering and nearly instantaneous internet in every corner of the world. But experts worry it may come at a hefty cost for space expl
oration. Nearly half of the world's population does not have access to the internet, because most internet options require an extensive track
of costly underground cables, leaving many rural locations offline. And while satellite internet
can reach those areas... Dave Mosher: Traditional
satellite internet is provided by a bus-sized spacecraft that is launched 22,236 miles into space in orbit around Earth. Narrator: That distance
means the satellite can reach places that cables can't. But since
that one satellite is meant to service a lot of people, its data capability is limited, which then limits connection speeds. And that signal has to travel a long way, creating a lot of lag. This is where Elon Musk
and SpaceX come in. Mosher: Starlink is a
globe-encircling network of internet-beaming satellites that is trying to get you online no matter where you are in the world. Narrator: And there's a
rather persuading element for SpaceX as well. Mosher: Elon Musk has said
he's just trying to
grab a small percentage of a
trillion-dollar-a-year telecommunications
industry around the world. If SpaceX can pull this off, the company could net about
$30 to $50 billion a year. Narrator: Musk and SpaceX
president Gwynne Shotwell say that much money could single-handedly fund the development
of Starlink, Starship, and SpaceX's Mars-launch infrastructure. As of early October, SpaceX has launched more than
700 satellites into orbit, with a plan to release a total of 12,000 over the next five y
ears, half of them by the end of 2024. And Musk wants to add
another 30,000 to that, coming to a total of 42,000
satellites circling Earth. All of these satellites
will also be much closer, anywhere from 200 to 400 miles above the planet in low-Earth orbit. Mosher: This reduces the connection delay that is found with traditional
internet satellite. Narrator: Once in orbit, these Starlink satellites will
be constantly on the move, which is why so many are necessary. Mosher: The problem is you
hav
e to have many satellites orbiting to make up for the fact that you can't stay in one
spot above the Earth. Because you need several
satellites overhead at any one time to cover many users. Narrator: Every satellite will connect with several others via laser beams, creating something like
the network's backbone. And to actually bring this
internet into your home, you'll need to get a pizza-sized antenna. This phased-array antenna can aim its beam at whatever satellite is overhead, which will mai
ntain an
internet signal in your home. But this scheme isn't without problems. Starlink satellites are bright. They reflect the sunlight and
shine it back towards Earth, so they end up looking
like bright moving stars. As cool as it may look,
that comes with problems. Mosher: Starlink
satellites are most visible in the night sky right before
dawn and right after dusk, which is the exact time that astronomers are hunting for near-Earth
objects or asteroids, objects that could hit
Earth and possib
ly harm us. Narrator: And as more satellites go up, so does the likelihood that they'll interfere with astronomers' views. Mosher: If Starlink
continues to be a problem for these type of sky surveys, we may not have as much notice as we want to detect a near-Earth object and thwart it and prevent
it from hitting Earth. Narrator: Beyond detecting
deadly asteroids, the wall of satellites could also obstruct the search for new planets
or even black holes. Mosher: SpaceX realized it had
to do someth
ing, and it did. It created what's called a DarkSat, which is a satellite that
has all of its shiny parts coated in a very black, dark material. Narrator: It also tried adding visors to shield those shiny
parts from the ground. But unless the satellites are cloaked like a spaceship in "Star Trek," technology that does not exist, none of this will fully solve the problem. And even if it did, there is
a much bigger issue at hand. Mosher: There's a concern
about space debris, because when you have
so many satellites in the closest, tightest,
densest orbits around Earth, there's a higher chance
that those satellites could collide with each other
or with other satellites. Narrator: Those crashes would create clouds of debris that can orbit the Earth for years, decades, or even centuries. Mosher: And that debris can then disable or cause other satellites to crash into each other,
creating even more debris, and this problem spirals out of control in an effect called the Kessler syndrome. And
if we reach that, then essentially space
is too unsafe to access. Narrator: To be clear, the risk of a runaway Kessler syndrome is very low. Mosher: But the potential
impacts of that are so high that scientists are working very hard to control such an event
from ever happening. Narrator: SpaceX has said its satellites can automatically move out of
the way to avoid collisions. But dozens of SpaceX
satellites are already disabled and can't move at all,
posing a potential threat. And those concerne
d with SpaceX's plans are lobbying the FCC
to rein in the company and more strictly
regulate low-Earth orbit. And that could make it more expensive and harder to deploy the
planned 42,000 satellites. But it doesn't stop at Starlink. Amazon's Kuiper project, OneWeb, China's Hongyan, and other projects are looking to challenge SpaceX by launching their own global networks of hundreds or thousands of satellites. If they all got their way
with little to no regulation, we could end up with 100,000 sa
tellites encasing our planet
within the next 10 years, dramatically increasing the risk of blocking off space for everyone.

So elon wants us to play raid shadow legends with no lag. Good guy.
"bus sized Satellite.." "Pizza sized antenna.." American alright
I hope he doesn't. I'm an amateur astronomer returning to the hobby after about 25 years, and the number of artificial satellites up there now is unbelieveable. Wherever you look in the sky within 5 or 10 minutes one will obstruct your field of view, or more than one going in different directions. Sometimes you'll see two or threee moving along together. It used to be "Wow, there's an artificial satellite....
Wonderfully demonstrated. Loved your presentation. It was a concise, comprehensible, and a detailed video at the same time.
Geez, just make a dyson sphere around the sun already.
Aliens studying about Earth: What are those floaty thingies and why are there 42 thousand of them?
I laughed when he said "detect a near Earth object and stop it from hitting Earth!" 🤣🤣🤣 Like as if we have the capability to stop a large Asteroid from hitting Earth.
Im a satellites historian I like looking at the old satellites from the 60s-70s especially Cosmos, I research them and determine things such as when it will plummet back to earth and such. Its gonna be a pain to search for older satellites with all these starlink satellites, but imagine all the space debree over the next 100 years....
Aliens: Hey earthlings, what’s y’all’s WiFi password?
year 2055: ew the internet so slow, we only have 10 terabyte of internet :(
This seems cool, just as long as this STAYS "StarLink" and DOES NOT transform into anything like "SkyNet."
Imagine playing Cod using Starling and then you hear some Alien talking in the chat😂.
Wall-E Predictions were right...
The scene of WallE blasting through the atmosphere which is literally covered in a layer of space debris...that scene comes to mind
They must have considered pushing dead satellites into deep space or at least in the direction of some place with the least risk. Could satellites be outfitted with a fail-safe rocket booster that sends the satellite away when it is no longer of use? Thank you for sharing helpful and informative videos!
I wooukd contribute. It's good thing Having this company to have the disruptive tech would be beneficial to us and there companies. It's good
You forgetting that in altitudes of 200 to 400 km any debry will experience strong atmospheric drag and will fall down and burn in the atmosphere within a few years. Not decades or centuries. Do your research right before spreading misinformation.
This is a very misleading video full of exaggeration and misleading graphics aimed at people who have no idea of the immense size of space or for that matter the planet.
The man who sill solve Lag, it's a blessing.
This is the worst nightmare for a astronomer
