Russia used highly toxic UDMH, SpaceX uses kerosene + LOX (huge amounts of Co2), as do India and China (kero the cheapest and most popular rocket fuel, pollutes the highest level of the atmosphere and lingers… Some are now using methane which is a worse greenhouse gas).
Liquid Hydrogen and Oxygen are just for specific stages.
But we’re talking 140 or more launches a year. I’m about as down for that as I am for keeping global tourism alive.
We don’t need satellites to track the weather or capture air quality data. The air, weather balloons, weather station, and radar is all we need.
The whole point of downsizing is to use less resources.
