“Light trains” in space

In the coming days, thousands of people around the planet, including Chile, will once again watch the passage of the now famous “light trains” that will move one after another for several minutes. They should not be confused with UFOs. They are Starlink satellites, launched on Wednesday, April 22, 2020.

At about 15:30, local time, a Falcon 9 rocket took off from Cape Canaveral, in the United States, carrying 60 new satellites, in the seventh launch of this kind by billionaire tycoon Elon Musk’s SpaceX company.

They will join the “constellation” of satellites already in orbit, whose objective is to provide broadband Internet services at low cost to the entire globe.

The first 60 of these devices were launched on May 24, 2019, and since then there have been another six launches.

Unlike other satellites and the International Space Station, the Starlinks have the peculiarity that they are several artifacts that move very close to each other and follow the same orbit.

For this reason, spotting them from the ground in the night sky can be very impressive for the observer, because they see “trains” of bodies similar to stars that can vary from 5 to 60 objects or more.


As it involves a large number of satellites, it is increasingly common for people to observe “trains of lights” in the night sky and report them as anomalous aerial phenomena.

The Committee for the Study of Anomalous Aerial Phenomena (CEFAA) has received dozens of reports for these sightings which, after being investigated, have turned out to belong to the “Starlink constellation”.

Through these articles, CEFAA collaborates in making the public aware of these technological advances so that their observation is not confused with “UFOs”.

In addition to the successful launch and deployment of the satellites, this time the Falcon 9 rocket, once again the carrier of the precious cargo, successfully landed on a SpaceX unmanned ship at sea.

Elon Musk has stated that SpaceX only needs about 400 satellites in orbit to provide “initial operational capacity” and, later, about 800 to make way for “significant operational capabilities.” That means that with this launch, SpaceX has already reached the minimum number of satellites that, according to Musk, are necessary to start operating the Starlink “constellation”.
