“So several times a year we’re taking these potshots at people on the Earth and fortunately so far missing. So far we’ve been very lucky, but it won’t last.”
Deorbiting Starlink satellites may not pose a risk to people, but Dr McDowell said they may still prove problematic.
Scientists are still trying to understand what impact this rate of deorbits might have on the Earth’s atmosphere.
I’m going to guess that “alarming rate” is something similar to the rate they were put up there.
With a lifespan of around five years, Starlink satellites are purposefully designed to burn up entirely in the Earth’s atmosphere before reaching the ground. So while the events may appear alarming as they streak across the sky, they are not dangerous.
IIRC this was by design. They’ve got a fairly short lifespan (only a couple years i think?) before they fall.
Why though? Isn’t that super wasteful?
The low orbit means they have more drag from the atmosphere. So to stay in orbit, the satellites need to spend fuel. That fuel runs out after a couple of years.
It is, of course.
I think it’s because of their low orbit and both the lower power required to talk to the satellite from earth, and smaller distances between satellites for meshing. It’s just my guess though.
I’m supposed to believe they entirely burn up on re-entry? Based upon Starlink’s word? Ok. Sure.
No, but given there are aproximately 6000 impacts a year from rocks of various sizes making it all the way to the ground a handful of extra impacts isnt going to make any significant difference. Maybe your chance of being hit by space debris in your lifetime rises from one in a billion to 1.1 in a billion.
*predictable
What a lame, dishonest title.

They are in low orbit and meant to de-orbit at eol. It is better they do that than stay up there really. The article throws out a lot of fear mongering language then at least it follows up with the reasons it isn’t a problem mostly. Except they make it sound like these sattelites are hitting the ground , but really just some kind of space debree hits the ground. These are made to burn up and only one piece has ever been proven to hit the ground. That does mean it’s possible, but still unlikely.
