Starlink satellite brings fast internet to Artem Australia, but raises new concerns

Deep in the country of Martu, the Lawa Community Schools have new additions. On the roof is a sealed rectangle of squats. It is curved downwards, flat on top and angled towards the sky, making it a more familiar sight in Australian regions.

“As a teacher, the trustworthy internet has been quite a game-changing experience to attract students,” says Jamparri, who has been teaching at Punmu’s Rawa since 2022.

“The Lawa curriculum focuses on bringing children out of the country and teaching language, but having reliable access to the internet is essential to supporting student engagement within the classroom.”

Access to everything from documentaries to mathematics is increasing. This is a resource that is taken for granted in the city.

This is to complement the school’s interactive learning approach and meet children and communities.

“In my class, I wanted to introduce Minecraft Education, a game that many kids play at home and play for fun,” says Jamparri.

“With StarLink, I was able to actually bring it into the classroom.”

Fast, reliable, and make a difference. But how does it work?

It’s closer to space than anywhere else

As anyone who has a hard time getting decent WiFi in the back room knows, the closer you get to the internet, the faster and more reliable.

“There was definitely that old connection and sometimes the internet was trapped from the weather,” Jeanpali said.

“They’re definitely difficult at the time, because you didn’t have that many tools to attract students.”

These old connections used satellites locked in “Earth Measuring” orbits.

At that exact altitude, the spacecraft puts the Earth in orbit exactly 24 hours a day, and when the planet bends beneath them, they always point to the same part of the planet.

The advantage is that you only need to build one satellite to cover a particular area, but the disadvantage is that the satellite must be 35,000 km apart for work.

Starlink takes a different approach. Closer satellites make much faster connections.

The StarLink satellite is in orbit just 550km above. For comparison, the closest major town to Punmu in Port Hedland is 600 km away.

Its low altitude is why Starlink works so well for remote communities. Towns like Punmu are closer to space than anywhere else.

At that height, the satellite zips overhead in just a few minutes. You need them more to make sure the other is already within range when it disappears on the horizon.

Thousands more.

It’s the moon (lock)

According to Dr. Ellie Sansam, director of Global Fireball Observatory, that’s why Starlink makes “megaconstellation” different from what we’ve seen before.

“I think the big thing about Starlink is the amount of how much you can get there,” Ellie says.

Ellie helps run a network of cameras on the outback, where the main task is to enter the atmosphere of meteors and track down falling metstones.

But more and more, they have seen something else.

Starlink satellites are so low that they glide over the top of the atmosphere. They need fuel to rise, and, importantly, it is necessary to dodge other satellites. If that fuel runs out, otherwise it breaks down, it’s time to re-entry.

“These satellites have a nominal five-year life,” says Ellie. “They can’t stay there forever.”

The first large batch of Starlink satellites entered space in 2020. So many people are planning to come back this year.

“We usually get one or two reentries per year in Australian airspace,” Ellie says.

“Current estimates are that by 2030 there will be 1,400 objects per year.

“And many of them are planned to be off in unattended areas of Australia.”

“Not undertaken any tactics” – except for remote communities like Punmu.

Dice and fireball

That’s not to say that Jeanpali and his students dodge the fall of the spaceship every time they go out into the country. Most will be “spaceship cemeteries” in the Indian and Pacific Oceans.

But, as Ellie points out, things don’t always go where they are.

“If there are many low-risk events, it increases.

For a preview of what it is, she points out the 2022 re-entry of SpaceX capsules in New South Wales.

The camera saw a mass of capsule material becoming a settlement, but Ellie’s team used weather radar to detect even more.

Ellie says he saw at least 6,000 km2 of the national park and dust clouds spreading across the surface of Canberra. Yikes.

Unanswered Questions

Regardless of how you feel about Starlink or its deeply problematic owner, MegaconStellations seems to stay here.

SpaceX’s competitors Amazon Project Kuiper, China’s Guowang and European OneWeb are all preparing to compete for Starlink’s estimated $8 billion annual revenue.

Connection promises are too convenient to ignore.

“We had a reliable internet, so it actually became a huge part of the community because students and teachers have access to it while they are in school,” Jeanpali said.

“You can also connect to important services like banks and Centrelink and do all of those life managers. [they] In many cases, it cannot be done at home. ”

Ellie and the team use Starlink for fieldwork and agree that it makes things easier.

“It was really convenient to have access to the supercomputer on a field trip rather than taking out the equipment with us,” Ellie says.

However, our impact on the sky is well documented, but our planets are not.

“People certainly assume it’s well thought out and planned,” Ellie says.

“The problem is, we don’t know. We don’t have a way to actually make sure that they’re coming down in areas where they’re not short of shortages, or that they’re shortages or that they’re coming down at all.”

“There are a lot of unanswered questions people don’t ask because people just want to stick to the greatness of what it’s doing, and I think I’m responsible for asking those questions.”
