A video recorded over Puerto Rico on February 7, 2022, shows a string of lights crossing the sky. Contemporaneous reporting identified them as Starlink satellites reentering after a geomagnetic storm increased atmospheric drag on satellites launched days earlier. The exact number that deorbited is disputed: SpaceX said 38, while Futurism reported 40 affected.
What does the Puerto Rico video show?
The three-minute YouTube video, uploaded by kevinizooropa under the title “Space debris over Puerto Rico (2/7/2022) SAC,” was recorded over Puerto Rico on February 7, according to contemporaneous coverage by Hindustan Times. The report relayed satellite observer Marco Langbroek’s assessment that the lights’ path and an orbital fit were consistent with the Starlink orbital plane. That is an attributed identification, not an independent verification of the footage or orbital calculation here.
Futurism published the video in its February 10, 2022, report, describing the lights as Starlink satellites burning up after a launch and geomagnetic storm. The footage is a visual record of luminous objects crossing the sky; it does not by itself establish how many satellites were involved or what happened to every component. Futurism’s report

SpaceX attributed the premature deorbit to increased atmospheric drag from a geomagnetic storm. The satellites had been launched on February 3 aboard a Falcon 9, according to Futurism’s account. Drag is the resistance an object encounters as it moves through the atmosphere. Although the air is extremely thin at satellite altitudes, it can still slow a satellite; as a satellite loses speed and orbital energy, its orbit lowers and it encounters denser air, which increases the drag further.

During reentry, the interaction with the atmosphere heats the surrounding air and spacecraft, creating the bright streaks visible from the ground. This explains the general mechanism behind the company’s account; it does not independently establish the condition of every component in this specific event.
How many Starlink satellites fell out of orbit?
The contemporaneous accounts give different figures and use different wording. They should not be treated as interchangeable:
| Source | Reported figure | How it was described |
|---|---|---|
| SpaceX | 38 satellites | Prematurely deorbited because of increased atmospheric drag from the geomagnetic storm. |
| Futurism, February 10, 2022 | 40 satellites | Reported as having fallen out of orbit shortly after deployment. |
Futurism said the February 3 launch carried 49 Starlink satellites. Hindustan Times attributed to SpaceX a statement that drag was 50 percent higher than in previous launches. That figure is SpaceX’s reported comparison, not an independently established measurement in the cited coverage. The available accounts do not resolve why the reported counts differ.

Why launch satellites into a low orbit?
SpaceX says Starlink satellites are deployed at low altitudes so that a satellite that fails initial system checks can be removed from orbit more quickly, either using its thruster or passively through atmospheric drag. In the company’s words: “By deploying the satellites into such low altitudes, in the rare case where any SpaceX satellite does not pass initial system checkouts, it is quickly and actively deorbited using its thruster or passively by atmospheric drag.” SpaceX’s Starlink update
That design approach makes drag useful as a way to bring a spacecraft down, but it also means satellites in low orbits can be more vulnerable to changes in atmospheric conditions. In this case, SpaceX said the geomagnetic storm increased drag enough to cause the premature deorbit of 38 satellites.
Does “burning up” mean no debris could reach the ground?
SpaceX says its satellites are designed to demise during reentry and that it had received no reports of debris after successful satellite deorbits. Those are company statements about the design and its reported experience. They do not independently verify the fate of every component in this particular event, so the video should not be taken as proof that every part always burns up completely or that ground risk is universally zero.
