This is a great read and unironically I want to subscribe to the substack, which is titled "Mars for the Rest of Us." The author is that Ceglowski of Pinboard and occasional space essays at idlewords.com, both of which make this self-recommending for me at least.

It's a cliche that space exploration creates discoveries that improve life back here on Earth. In the topics discussed in this essay, water reclamation and waste recycling especially, the future solutions developed I think will lead to improvements for terrestrial living.
