Orbital 'parking spots' could help prevent satellite traffic jams

 With the rapid growth of the space industry in recent years, the number of satellites in orbit has increased dramatically. As of August 2023, there are over 4,800 active satellites in orbit around Earth, and this number is expected to grow to over 100,000 by 2030.

This increase in satellite traffic has raised concerns about the potential for collisions. In 2009, a defunct Russian satellite collided with an active US communications satellite, generating over 1,000 pieces of debris. In 2021, there were two more close calls between satellites, one of which involved a Chinese rocket body that came within 19 meters of hitting a Starlink satellite.

One way to reduce the risk of satellite collisions is to assign satellites designated "parking spots." This would be similar to how airplanes are assigned runways and airspace. By giving satellites specific locations to stay in, operators could help to prevent them from getting too close to each other.

There are a few different ways that orbital parking spots could be implemented. One option would be to create a global database of satellite locations. Operators could then use this database to check the location of other satellites before moving their own spacecraft.

Another option would be to develop a system of traffic control for satellites. This system could use sensors to track the location of all satellites in orbit and issue warnings to operators if their satellites are getting too close to each other.

Regardless of how it is implemented, a system of orbital parking spots would have a number of benefits. It would help to reduce the risk of collisions, improve safety for satellites and astronauts, and make space more accessible to new operators.

Benefits of orbital parking spots

There are a number of potential benefits to assigning orbital parking spots to satellites.

Reduced risk of collisions: 

The biggest benefit of orbital parking spots is that they would help to reduce the risk of collisions between satellites. This is especially important in low-Earth orbit (LEO), which is the most congested region of space.

Improved safety for satellites and astronauts:

 Satellite collisions can create debris, which can pose a hazard to other satellites and astronauts. By reducing the risk of collisions, orbital parking spots would help to improve safety for everyone in space.

Increased access to space: 

Orbital parking spots would make space more accessible to new operators. This is because new operators would no longer have to worry about finding a safe place to place their satellites in orbit.

Challenges of orbital parking spots

There are also a number of challenges that need to be addressed before orbital parking spots can be implemented.

Coordination between operators: 

One of the biggest challenges is coordinating between different satellite operators. This is because each operator has its own goals and objectives, and they may not always agree on the best way to implement orbital parking spots.

 Enforcement:

 Another challenge is enforcement. Even if operators agree on a system of orbital parking spots, there needs to be a way to enforce it. This could be done through a regulatory body or through a system of peer pressure.

Cost

Implementing a system of orbital parking spots would be expensive. This is because it would require developing new technologies and infrastructure.

Potential solutions to the challenges

Despite the challenges, there are a number of potential solutions that could be used to implement orbital parking spots.

Coordination between operators: 

One way to coordinate between different satellite operators is to establish a global regulatory body. This body could be responsible for developing and enforcing rules for orbital parking spots.

 Enforcement:

 One way to enforce a system of orbital parking spots is to use a system of peer pressure. This could involve publishing a list of operators who are not complying with the rules.

Cost

The cost of implementing a system of orbital parking spots could be reduced by partnering with the private sector. For example, private companies could be responsible for developing and operating the infrastructure needed to track and manage orbital parking spots.

Conclusion

Orbital parking spots have the potential to help prevent satellite collisions, improve safety for satellites and astronauts, and make space more accessible to new operators. However, there are a number of challenges that need to be addressed before orbital parking spots can be implemented. These challenges include coordinating between different satellite operators, enforcing the rules, and covering the cost.

Despite the challenges, there are a number of potential solutions that could be used to implement orbital parking spots. One way to coordinate between operators is to establish a global regulatory body. Another way to enforce the rules is to use a system of peer pressure. The cost of implementation could be reduced by partnering with the private sector.

As the space industry continues to grow, it is important to develop solutions to the challenges posed by the increasing number of satellites in orbit. Orbital parking spots are one potential solution that could help to reduce the risk of collisions, improve safety, and make space more accessible.

It is also important to consider the impact that orbital parking spots would have on other space activities. For example, orbital parking spots could potentially interfere with scientific research or with the operation of spacecraft that are not used for communications or Earth observation.
