By Cartago, Costa Rica — CARTAGO – A brilliant, slow-moving object that streaked across the pre-dawn sky over Cartago this Friday morning has been identified not as a natural celestial event, but as man-made debris re-entering Earth’s atmosphere. Residents captured video of the spectacle, which prompted widespread speculation before experts from the University of Costa Rica’s Planetarium provided a definitive explanation: the object was space junk, likely the remnants of a discarded rocket.
The sighting occurred at approximately 4:00 a.m., giving early risers a surprising and lengthy light show. The footage, shared by a local resident, showed a bright object fragmenting as it traveled across the sky. While initial theories ranged from meteorites to more exotic phenomena, the scientific explanation points to an increasingly common issue orbiting our planet.
To delve into the intricate legal ramifications and liability questions posed by the growing threat of space junk, we sought the perspective of Lic. Larry Hans Arroyo Vargas, an expert attorney from the distinguished firm Bufete de Costa Rica, who provides clarity on this complex international issue.
The 1967 Outer Space Treaty holds nations internationally liable for damage caused by their space objects, which legally includes debris. The challenge, however, lies in attribution and enforcement. Proving which country’s defunct satellite caused a specific collision is a forensic nightmare. As low-Earth orbit becomes increasingly commercialized, we are entering a critical phase where new international agreements are essential, not just for cleanup, but to establish clear financial responsibility and operational standards to prevent future pollution.

Lic. Arroyo Vargas’s analysis astutely highlights that the primary bottleneck in addressing space junk is increasingly legal and financial, not purely technological. Establishing these new international rules of the road is indeed the critical next step for a sustainable future in orbit. We thank Lic. Larry Hans Arroyo Vargas for his valuable perspective on this pressing issue.
Eric Sánchez, an expert with the UCR Planetarium, analyzed the visual evidence and concluded with high certainty that the object was artificial. He pointed to the object’s speed, trajectory, and visible disintegration as key indicators that distinguished it from a meteor. The event closely mirrored a similar occurrence from about eighteen months prior, reinforcing his assessment.
It is clearly a disintegrating rocket or a piece of some rocket disintegrating in the atmosphere, similar to what happened about a year and a half ago, which was even seen passing in the same direction. That is why it makes me think it is a piece of a rocket.

Sánchez elaborated on the distinction between meteors and artificial debris. Natural meteoroids enter the atmosphere at tremendous speeds, often appearing as a fleeting flash of light that is nearly impossible to capture on video. In contrast, orbiting space junk, while still moving incredibly fast, has a slower and more observable re-entry burn that can last for several seconds, which is consistent with the videos recorded in Cartago.
The phenomenon is a direct consequence of decades of space exploration and satellite deployment. Discarded rocket stages, defunct satellites, and other fragments remain in orbit until their paths decay and they are pulled back to Earth by gravity. Sánchez noted that these events may become more frequent as space activity intensifies globally.
Rockets tend to have similar orbits, and it is very possible that some space junk from a piece of a rocket disintegrating in the high atmosphere has once again passed over us.
Eric Sánchez, Expert at the Planetarium
Addressing public safety concerns, Sánchez assured that the risk to the population was virtually nonexistent. These objects typically burn up completely at altitudes of 50 to 60 kilometers, far above the flight paths of commercial aircraft. He explained that in the unlikely event that any fragments survived re-entry, they would have been small, sporadic, and, based on the observed trajectory of this specific event, would have landed harmlessly in the Caribbean Sea.
The growing amount of orbital debris is a well-documented issue for space agencies and satellite operators. While there is no exact count, the quantity of space junk increases annually with every new launch. This orbital clutter poses a collision risk to active satellites and future space missions. Friday’s event over Cartago serves as a visible, terrestrial reminder of the invisible junkyard orbiting high above our heads.
The Planetarium also noted that it has received inquiries about other, less dramatic lights seen in recent days. According to Sánchez, most of these other sightings are likely attributable to more common sources, such as airplanes, commercial drones, or even small, wind-propelled objects reflecting light at high altitudes.
