Space Congestion Raises Collision Concerns for Orbital Safety

ASTANA, July 15 — The orbital economy is getting crowded, and the bill for traffic management is coming due. Data from the U.S. Space Force shows it now tracks over 40,000 objects in orbit, a figure that includes both active satellites and debris. For a Central Asian nation like Kazakhstan, whose Baikonur Cosmodrome has launched much of the world’s hardware into that domain, the stakes are direct: a clogged orbit raises insurance premiums, complicates launch windows, and threatens the communications infrastructure that links regional markets to global finance.

SpaceX’s Starlink constellation alone accounts for over 5,000 satellites in that tracked population. Amazon’s Project Kuiper has plans for an additional 3,236 satellites.

The European Space Agency reported in 2023 that there are over 36,500 debris objects larger than 10 centimeters in orbit. That is the size of a standard dinner plate, and each one travels at speeds that can shatter an operational satellite on impact. The near-miss record is already mounting.

In 2021, China’s Ministry of Foreign Affairs formally complained that Starlink satellites nearly collided with its Tiangong space station. In 2022, the European Space Agency performed a collision avoidance maneuver for its Aeolus satellite due to a Starlink satellite.

These are not theoretical exercises. Each avoidance burn consumes propellant, shortens a satellite’s operational life, and costs the operator money.

The Kessler risk and the regulatory response

The underlying physics problem has a name. NASA scientist Donald J. Kessler proposed the Kessler Syndrome in 1978, a theoretical scenario where debris collisions cascade uncontrollably.

One collision creates more debris, which raises the probability of further collisions, until the entire orbital band becomes unusable. For Kazakhstan, which relies on satellite links for oil and gas pipeline monitoring across the Caspian basin, that scenario would mean direct economic disruption.

The Federal Communications Commission now requires satellite operators to provide collision avoidance plans before receiving launch licenses. That rule applies to every operator seeking U.S. market access, including the mega-constellations that are the main drivers of orbital congestion. The requirement is a regulatory floor, not a ceiling.

The data shows the number of tracked objects has grown steadily, and no international treaty governs right-of-way or debris removal in space.

What to watch next

The commercial pressure is only rising. More than 40,000 objects are now tracked, but the figure does not include debris smaller than 10 centimeters that can still disable a satellite. The U.S. Space Force, ESA, and national space agencies are all developing better tracking systems.

For the satellite operators and the launch providers who serve them, the cost of collision avoidance — and the risk of a Kessler event — is becoming a line item on the balance sheet. Kazakhstan’s space industry, built on the legacy of Baikonur, will be watching how that math adds up.
