Starlink (SpaceX) Satellites Do Fancy Dance Moves to Stay Safe, But There’s a Worrying Problem!
SpaceX’s Starlink satellites have been doing impressive maneuvers to avoid bumping into other spacecraft and space junk. In just six months, from December 2022 to May 2023, they had to swerve over 25,000 times! That’s twice as many moves compared to the previous six months. Since the first Spacex Starlink satellite launched in 2019, they have made over 50,000 moves to prevent collisions.
But here’s the concern: the number of maneuvers is increasing fast, like on a roller coaster going higher and higher. This worries experts because it could become difficult to manage and keep everyone safe in space. Hugh Lewis, a professor who knows a lot about satellites, says the number of moves is growing quickly. It’s doubling every six months, and that’s a problem because big numbers can be hard to handle.
So, while it’s cool that Starlink satellites can avoid crashes with their cool dance moves, we need to figure out how to keep everything safe up there in space!
1.000.000 Moves till 2028
“Starlink Satellites Are Doing More and More Avoidance Moves!”Did you know that Starlink satellites have to do special maneuvers to avoid crashing into other satellites? In the first part of 2021, they did 2,219 of these moves. Then, in the next six months, they did 3,333. After that, it doubled to 6,873 moves! In the second half of 2022, they had to change their paths 13,612 times to stay safe. In the latest report, they did 25,299 moves in just six months, which means each satellite had to move about 6 times on average.
This is a big problem because the number of moves keeps getting bigger and bigger. Every six months, it doubles! In just two years, it went up by 10 times. If it keeps going like this, in the next six months, they might have to do 50,000 moves, then 100,000, and even more!
By 2028, they might have to move nearly a million times in just six months! That’s a lot! And this seems to only increase. SpaceX has already put about one-third of its planned satellites in space, and they’re launching more than 800 satellites each year. Other companies like Amazon and China are also trying to send their satellites into space.
It’s a big challenge to make sure all these satellites can move around without crashing into each other. But people are working on it to keep space safe and make sure everything goes smoothly up there!
Satellite Traffic and Safety Concerns in Space
There are a lot of satellites in space—over 1.7 million of them! They are registered with an organization that oversees satellite radio frequencies. But not all of those satellites will actually be launched. Still, the numbers are so high that experts are worried about keeping order in space.
If there are around 100,000 active satellites by the end of this decade, there will be a huge number of maneuvers needed to avoid collisions. It’s like driving on a highway and constantly swerving to avoid hitting something. That’s not very safe!
The need to swerve isn’t just because of new satellites. There’s also a lot of space debris, like old satellites and rocket parts, floating around. This makes it even harder for satellite operators to keep their spacecraft safe.
Experts question if SpaceX, a big satellite company, can keep up with all the alerts for potential collisions. They think the risk of collisions will keep going up, even if SpaceX tries hard to prevent them.
There’s concern about situations where no maneuvers are made. Even though the chance of a collision is low in each case, there are so many of them that it becomes a big risk. It’s like buying a lot of lottery tickets—you’re more likely to win if you have a million tickets instead of just one.
Unless regulators limit the number of satellites in space, experts believe collisions will become common. This would create more space debris and lead to even more collisions. It could eventually result in the Kessler Syndrome, where collisions happen so often that parts of space become unusable, like in the movie “Gravity.” So, it’s important to figure out how to manage all these satellites and keep space safe for everyone.
