WHATS FLOATING UP THERE?

I was just looking at flight radar traffic, when I spotted something different, a ball like round shape icon instead of an airplane. My surprise came when I saw the altitude and speed it was flying.. 😱 Also, I had never hear of that name : RAVEN AEROSTAR

If you are like me and want to satisfy your curiosity, you will enjoy this next blog about these stratospheric balloons.

Look at the altitude!

First things first: when we talk about Raven Aerostar “balls,” we’re really talking about giant, pumpkin-shaped balloons that soar up to 20 kilometers (over 60,000 feet!) above the Earth. Picture a balloon as big as a house, made from super-strong plastic, filled with helium, and carrying a payload of electronics, cameras, or even internet routers. That’s the basic idea—but the magic is in the details.

How Do They Work? (Hint: It’s Not Magic, But It’s Close!)

Here’s where things get really cool. These balloons can float for weeks—even months—at a time. But how do they stay up there, and how do they know where to go?

- Altitude Control: Inside each balloon is a clever “ballonet”—think of it as a balloon within a balloon. By pumping air in or out, the Aerostar team can make the whole thing rise or fall, catching different wind currents at different heights. It’s like surfing invisible rivers in the sky!

- Steering by Wind: They can’t steer like an airplane, but by changing altitude, they “ride” the winds in different directions. With the right planning, they can drift across continents or hover over a single spot for days.

- Remote Control: Operators on the ground can send commands to the balloon from anywhere in the world, thanks to a system called Thunderstorm (yes, that’s really what it’s called).

Why Send Balloons to Space? (Well, Almost Space…)

So, what are these floating giants actually doing up there? Turns out, quite a lot:

• Connecting the Unconnected: Remember Google’s Project Loon? Raven Aerostar helped make it happen, using balloons to beam internet to remote places where cables and towers can’t reach.

• Eyes in the Sky: The military uses these balloons for surveillance and communication. They can keep watch over huge areas—quietly and for a long time.

• Science on the Edge: From studying the ozone layer to monitoring weather or tracking wildfires, these balloons give scientists a unique, bird’s-eye view of our planet.

• Fun Facts to Impress Your Friends

• Endurance Champions: Some Aerostar balloons have stayed aloft for over 30 days!

• Eco-Friendly: They use solar panels for power, making them surprisingly green.

• Recoverable: When the mission’s done, they can be brought down gently and reused.

  
  

The Sky’s Not the Limit—It’s Just the Beginning

The trajectory of the balloon

The next time you spot a tiny white dot drifting waaaay up high, you might just be seeing a Raven Aerostar balloon in action. These gentle giants are quietly revolutionizing everything from internet access to environmental science—all by harnessing the power of the wind and a little bit of helium.

Who knew that something as simple as a balloon could be one of the coolest, most innovative tools in the modern world? The sky, as they say, is just the beginning.

Stay curious! The world above our heads is full of surprises—sometimes, all you have to do is look up.
