Besides these two back-to-backs, I have not heard of other micrometeorite damage to soyez coolant systems - I am sure others know more than me.

Given that this has been in the news, including testing of the empty descent, this seems novel, and not at all routine. So we are not looking at a sample size of 2, but of ALL Soyuz -- which have been in service for decades, no?

Good observation that the station should provide context on strikes (if not damage).

The moon is a fragment of an ancient planet named Theia. It collided with earth and the molten remnants formed into a sphere by gravity. I'm pretty sure there isn't anything weird about the moon being circular like that. There are literally remnants of the planet sticking out of our crust and core of the planet recently mapped.

The point I am trying to make is that we need solutions. And the solution cannot be throw it in the ocean, we have already thrown more things in the Ocean than we ever should have. The average person has no idea that there are all kinds of harmful organisms all around us in the air we breathe, if we killed all those organisms the planet would die and it wouldn’t take very long. Yet we just go about our business, completely oblivious. We are killing this planet, the first step in saving it is stop killing it. The popular answer here is plunge it in the Ocean. That cannot be the right answer. The easiest way to do something is sometimes the worst way and causes more problems than it solves.

Some more information about this:

The burst was so bright it effectively blinded most gamma-ray instruments in space, which means they could not directly record the real intensity of the emission. U.S. scientists were able to reconstruct this information from the Fermi Telescope data. They then compared the results with those from the Russian team working on Konus data and Chinese teams analyzing observations from the GECAM-C detector on their SATech-01 satellite and instruments on their Insight-HXMT observatory. Together, they prove the burst was 70 times brighter than any yet seen.

No, you just didn't quite read the comment you replied to.

I generally prefer to include engine development in vehicle development, but plenty of people disagree especially when the engine development happened before the development of a particular vehicle. Merlin was developed for Falcon 1, though there were continued improvements over time.

No one who read that source and understood the context would honestly say "Elon isn't being completely honest or more likely is miscategorizing costs somewhere". You were just confused.
