Reply to comment by EarthInteresting9781 in As an avid lover of the cosmos, is it realistic to expect space tourism and a mars and moon resort before I die? by EarthInteresting9781

I actually don’t know, but I really doubt it.

The largest issue is that the soot from rockets is something like 500 times worse than normal soot and is absolutely horrible for the ozone layer. When these corps are questioned about environmental impact they typically dodge the question or compare it to the aviation industry which is a crock.

They very well may develop clean alternatives however so long as there is a demand but that also may increase costs in the short term and may hinder your goal.

I'm not sure that hydrogen or methane powered engines produce very much soot at all.

They absolutely do produce soot, and the production of hydrogen is horrible for the environment as well.

Methane is not so bad. Still produces soot but not nearly as bad.

Space X uses kerosene and liquid oxygen.

Virgin galactic uses HTPB and liquid nitrous oxide

Blue origin uses liquefied natural gas.

I do hope for alternatives for commercial use but am also very hesitant to support en made space tourism at the moment.

But you’re correct in that hydrogen and methane are cleaner that what is used now

How? Hydrogen and Oxygen yield water. Where does the soot come from?
