The smaller rocks are composed of those materials in solid state (e.g., ice not water). They are less irradiated as they are further away from the Sun (think the asteroid belt and beyond). Atmospheric entry (if that's what you mean) is irrelevant. What matters here is the transport of materials from a place where they could have formed, to a place where they couldn't.

The timing of the delivery is what's important here. These building blocks, organic matter, and water would have been depleted in the proto-Earth due to Solar irradiation. There needs to be some mechanism that delivers these ingredients from the outer Solar System. Bombardment by smaller rocks makes the most sense, and was likely triggered by the migration of Giant Planets, leading to a period of heavy bombardment (on a bare Earth -- no oceans, no volcanoes).. https://en.wikipedia.org/wiki/Nice_model

I worked in a national Japanese Lab for a year. For me, the illusion of tech advancement was shattered when I was told I needed to fill-out a form by hand to get access to a high-performance computing facility. I got my login and pass info about 5 business days after I mailed my application form by post.

Would you describe a parasite that kills its host as efficient?

Earlier this year, NASA selected two missions to Venus as finalists for the next Discovery-class mission, DAVINCI+ and VERITAS: https://www.nasa.gov/press-release/nasa-selects-four-possibl...
It's unclear if these missions are currently designed to be able to detect phosphine though.

While this is true when considering the total sum of the DoD budget, I think it would be more fair to compare the DoD's R&D budget -- which stood at something like $60B vs. NASA's $21B total... which really makes you wonder.. Anyway, along with people with stars on their shoulders, you can also piss off a congress-person who has a large NASA facility in their district..

Again you make wild false claims..
The first major breakthroughs for understanding nuclear fusion came because we wanted to understand what powered the Sun and Stars: https://en.wikipedia.org/wiki/Timeline_of_nuclear_fusion
.. and these events began 100 years ago.
Part of what you say is true, we make discoveries by looking at things.. Astronomy gives us more things to look at, and in energy regimes that cost many $$ to replicate in experiments on Earth..

The internet was created in a particle-physics laboratory: https://en.wikipedia.org/wiki/World_Wide_Web
In the last 100 years, advances in particle physics have been aided by our study of high-energy mechanisms in the universe (nuclear fusion in star systems, supernovae, acceleration of the expansion of the universe, etc.)..
so you have internet thanks, in part, to astronomy..
what a silly comment..
