In the vast realm of space, our growing fleet of satellites and space vehicles is reaching new heights. While this expansion is impressive, it comes with a unique challenge: space traffic jams and the risk of satellite collisions. To tackle this issue, engineers are proposing an ingenious solution – ‘Orbital Parking Spots.’ In this article, we’ll break down the concept of orbital parking spots, their significance, and how they can make space travel safer.

Why Orbital Parking Spots Are Needed

The number of satellites orbiting Earth is expected to increase tenfold by 2030, thanks to the rise of Earth-observation and communication satellites. This surge in satellite numbers poses a risk of congestion and potential collisions in space. To prevent accidents and ensure fairness in space usage, experts suggest assigning designated parking spots for spacecraft.

The Challenge of Satellite Constellations

Satellite constellations, networks of satellites working together, are also growing both in number and size. They serve various purposes, from GPS to Earth observations and internet access. SpaceX’s Starlink constellation, for example, has launched thousands of satellites and plans to send many more. However, the sheer scale and quantity of these constellations make them challenging to manage.

David Arnas, an assistant professor at Purdue University, highlights this issue. He emphasizes that the growing size and number of satellite constellations make it difficult to track them accurately, which could jeopardize long-term safety in space. Arnas underscores that space is a shared resource for humanity, and it’s crucial to ensure equitable access and responsible usage.

Organizing Satellites and Parking Spots

To address these challenges, a research team has been exploring ways to better organize satellites in space and coordinate parking spots. They’ve investigated how to quickly reconfigure large satellite constellations to avoid potential debris strikes that might cause damage.

In case of fragmentation events or unexpected situations, moving satellites is necessary. This involves optimizing not just their final positions but also planning the maneuvers each satellite needs to perform in a short time frame. Arnas explains that a structured approach, even one done with pen and paper, can foresee reconfiguration possibilities and rapid reactions when unexpected events occur.

Ensuring Safe Distances

Arnas has also developed a method for calculating the minimum safe distance between space vehicles. This calculation helps avoid potential collisions when debris knocks a satellite off course or when a spacecraft struggles to maintain its position. While there are currently limited policies regulating satellite placement in space, Arnas hopes that his tools will guide future decision-makers.


In summary, orbital ‘parking spots’ offer a promising solution to the growing problem of space congestion and satellite collisions. As our presence in space continues to expand, addressing these challenges becomes paramount. Researchers and engineers are working diligently to ensure that space exploration remains safe, organized, and accessible.

Space is a shared resource, and we have a responsibility to protect it for future generations. With the implementation of solutions like orbital parking spots, the future of space exploration can be both exciting and secure.


1. What are orbital ‘parking spots’?

 Orbital ‘parking spots’ are like designated parking spaces in space where spacecraft can safely stay to avoid space traffic jams and crashes. They help keep space orderly.

2. Why do we need orbital parking spots?

 We need them because there are going to be lots more satellites in space soon, and we don’t want them bumping into each other. Orbital parking spots help keep satellites and spacecraft from getting too close.

3. How many satellites will there be by 2030?

By 2030, there will be about ten times more satellites than there are now. This is because we’re sending up many new ones, especially for things like the internet and Earth observation.

4. What are satellite constellations, and why do they cause congestion?

 Satellite constellations are groups of satellites working together, but they can make space crowded. They’re a bit like groups of friends who want to stay close, but too many friends can cause problems.

5. How can we rearrange large satellite groups in space?

 We can rearrange them by planning where each satellite should be and making them move carefully. This way, they won’t run into each other or space debris.

6. Why is it important to share space fairly?

Sharing space fairly means making sure everyone gets a chance to use it. Space is like a playground for everyone, and we want to make sure it’s safe and fun for all.

7. How can tools developed by David Arnas help policymakers?

 David Arnas made tools that help policymakers understand how new space missions might affect space in the future. These tools use data to make good decisions about space.

8. Why is space called the “common resource of humanity”?

 Space is called this because it’s like air and water; it belongs to all of us. We should take care of it and make sure it stays nice for future generations.

9. How do orbital ‘parking spots’ make space safer?

 Orbital ‘parking spots’ make space safer by keeping spacecraft at safe distances from each other. This helps prevent accidents and keeps space activities safe.

10. What does the future look like with orbital parking spots?

 With orbital parking spots, the future of space exploration will be safer and more organized. We can keep exploring space without worrying about crashes and accidents.
