The first victim of space debris.




Instead when I tell you about the Kessler Syndrome, the Kessler Syndrome is a syndrome or a chain or cascading effect that was speculated by a NASA expert, called Frank Kessler, the issue is that this Kessler Effect would look poorly like what was seen in the movie Gravity. A satellite is destroyed by a small fragment of space junk or by a micro meteorite and that destroyed satellite becomes a pile of debris which begins to destroy other satellites which in turn transforms into another pile of debris that flies at high speed from topo debris to satelli destroying it the satellites, ships, space stations and everything else in orbit is destroyed and transformed into a papilla of wreckage traveling at high speed, completely disabling earth orbit and supposing an apocalypse of what is the satellite based civilization,which is now space itself.


On January 16, the Spanish Ministry of Defense declared or announced that the Spain SAT NG2 satellite has been destroyed, presumably by a piece of space debris or a micrometeorite. It is not yet clear which of the two things it could be. It is more likely that it is a piece of space debris because they are much more abundant in Earth orbit and right now the Ministry of Defense has commissioned the construction of another satellite, which would be the Spain SAT NG3.


This is not cheap at all, it is 1 billion euros that have gone to waste, luckily, this time there was insurance, which means it is covered by insurance, I say luckily this time because a few years ago, November 2020, the SEOSAT satellite was lost, in this case it was not due to a micrometeorite, the rocket simply exploded and it was 200 million euros and no one thought to ask for insurance.

This is not like when you buy an electronic gadget, a laptop or something and it puts you in the box there in the online store, that if you want to pay insurance for a few euros a month, you are losing 200 million euros that was lost at that time in 2020, luckily, this time there was insurance, but this satellite has been lost, which is crucial, although it does not affect what is the Spanish military defense communications and other communications that this satellite that cost 1000 covered. million euros.


What is known is that the failure was at 50,000 km altitude, this satellite is geostationary, the geostationary orbit is at about 35,000 km altitude, rounding up, it is not exactly 35,000, it was at 50,000 km altitude is the part that doesn't fit me, according to the statement it was at 50,000 km altitude because, well, you don't directly reach the geostationary orbit. You have to go through a series of previous orbits until you get into orbit, it was launched in October and it was in this orbit placement phase.


Either the statement is wrong or it doesn't fit me, I think it's wrong because it doesn't fit me. 50,000 km high is very rare, very rare that it was due to space debris, even a micrometeorite, because all that space debris is concentrated in low Earth orbit, it is fundamentally where most of the debris is, low Earth orbit, it is the orbit where, for example, the space stations are, at about 400 km high, it starts at around 200-odd km high and reaches approximately 1000 km high.


Then a little higher up there is also some garbage, but in the geostationary orbit, although there are some remains, there is very little garbage and at 50,000 km altitude, even less and this was in October and it has been known because they have tried to recover communications, since it has been known recently.

Anyway, the situation is that, 1000 million have been officially lost due to the impact of a micro meteorite or space debris, surely space debris, because there is a greater amount of space debris than micrometeorites and the worst is coming now, because it is not known in what condition this drifting satellite is in, if the impact destroyed the central computer or the energy system, it has been transformed into a zombie satellite, that is, it is not that it is a cloud of fragments, it may have released some remains with the impact, but in general it will be forming a piece, a still quite important block.


And this, if it becomes a zombie satellite, means that it could be unstable, which is also because it had just been launched, so the fuel tanks and batteries were whole and there is a risk of it exploding. If it explodes, it would create a huge cloud of thousands of fragments that would put the rest of the satellite fleet at risk, so maybe we will end up developing Kessler syndrome with a Spanish satellite.
