The cosmos is becoming increasingly crowded as more players enter the race to harness the vastness of space. Recently, a close encounter between a European satellite known for measuring the Earth’s winds and one of SpaceX’s Starlink satellites highlighted an alarming reality: our current systems for managing satellite traffic are woefully inadequate. As we continue to send satellites into orbit at an escalating pace, the necessity for automated space traffic management has never been clearer. This blog will delve into this critical issue, shedding light on the implications of satellite congestion and the potential solutions that lie ahead.

The Collision Avoidance Incident

In September 2019, the European Space Agency (ESA) announced a significant event on their Twitter feed—one that marked a new chapter in satellite operations. It was the first time they performed a “collision avoidance maneuver” not to avoid space debris or dead satellites, but to steer clear of another active satellite from SpaceX’s expanding Starlink constellation. This incident, although resolved without catastrophic outcomes, serves as a cautionary tale for the future of space travel.

Understanding the Dynamics of Space Traffic

When launching satellites, operators meticulously calculate orbits to prevent intersection. However, despite best efforts, mishaps can occur. Misfired thrusters or unforeseen operational issues can dramatically change a satellite’s trajectory, putting it on a collision course with another. In this case, an unexpected update altered the collision probability from a safe 1 in 50,000 to a concerning 1 in 600—well below the threshold for necessary preventive action—prompting ESA to act promptly.

• Miscommunication, Not Malice: The increase in threat level went unnoticed by SpaceX, causing a lack of coordination that nearly led to a disastrous situation. Their operator was simply not alerted to the gravity of the new risk.
• Fragile Operations: ESA’s satellite Aeolus was engaged in finely tuned, sensitive measurements at the time of the incident, adding an element of risk to the already precarious situation.

The Call for Automated Solutions

As many formidable entities like SpaceX, Amazon, and OneWeb embark on launching expansive satellite constellations, the likelihood of similar encounters increases exponentially. The existing communication methods—primarily emails and sporadic updates—are grossly inadequate for the task at hand. As ESA’s Holger Krag aptly pointed out, “space is not organized,” and current protocols rely on the goodwill and awareness of satellite operators rather than established traffic regulations.

Embracing Technology and Automation

Just as air traffic control employs structured protocols to manage the vast number of aircraft, space operations are now entering an era requiring a similar approach. The integration of artificial intelligence and enhanced communication protocols are key areas of focus that could lead to effective space traffic management. In essence, a move towards automated maneuver coordination will ensure that satellites can share the orbital space without jeopardizing each other’s missions.

Moving Towards a Collaborative Future

The challenge of managing space traffic is not only technical but calls for international collaboration. Establishing unified protocols for communication and maneuvering could significantly reduce the chances of near-misses in the future. This transition will not be quick or simple, but it is essential for sustainable space exploration.

Conclusion

The recent collision avoidance incident serves as a wake-up call for both governmental and commercial space organizations. As the cosmos fills with new spacecraft, the push for a sophisticated traffic management system becomes increasingly urgent. We stand at a crucial juncture where technology can lead the way to safer and more efficient operations in space.
