Actually with such a tiny payload requirement (100kg of machinery) you could do the entire thing on a Crew Dragon with an expendable Falcon Heavy, since that has over 16,000kg payload to TLI. The only thing missing is a space suit that's tolerable to live and work in for a couple of weeks straight.
>sardine mode capsule to lunar orbit
>suit up and EVA to unpack the service module
>ride LESS units down to surface
>set up micro camp with spaceblanket tents, air/food/water/waste transfer machines, etc. and cots to sleep on
>do initial work to build moonbase, resting at camp
>set up machines to do next phase unattended (drilling into cliff faces, ISRU bricks, etc.)
>ride LESS units back up to Dragon
>leave piss and shit bags in section of service module to burn up in atmo
>return to Earth

With the 4ASS standard 50t-TLI kickstage yeet train that gives you another ~35,000kg of payload to work with, which is some much nicer heavy machinery and a pressurized hab so you don't have to sleep in suits. Still LESS+Dragon for the way home though.

Absence of evidence is not evidence of absence. Just because we haven't discovered ayys, or traces of them, does not mean they don't exist or are very rare. In terms of astronomical time humanity has been around for the blink of an eye and only exploring for extraterrestrial life for a fraction of a fraction of our existence. We've barely scratched the surface in terms of space exploration and searching for extraterrestrial life.

We didn't even know for sure if planets existed around other stars until around 25 years ago when we had the first confirmed exoplanet discovery. Now we have discovered thousands of them and have determined planets are pretty common. We didn't get serious about listening for ayy radio transmissions until the 70s - again, almost nothing in terms of cosmic timescales. Despite that short timeframe, there has been one radio signal that we can't explain (look up the Wow signal). Doesn't mean it was sent by ayys but we can't dismiss it with any other explanation and it's the most promising hard evidence of an artificial radio signal. I'm really looking forward to the JWST. It should give us more clues on where to look for life. It will be able to analyze atmospheres of some exoplanets, which will give us prime SETI candidates.

tldr give it a few hundred more years of searching for life before definitively making any claims about how common it occurs

Panspermia might be plausible in more compact systems like the TRAPPIST system with 7 planets that all have a tighter orbit than Mercury has around our sun but it seems like a stretch for thicc systems like ours.

very cool. i love reading about Wernher von Braun and the NASA projects that lead to the moon landing. Building a rocket is the holy grail of engineering. A rocket looks so much simpler than a plane but is so much more complicated and powerful. A rocket has oxygen tanks that mixes with the fuel at the exit what is really amazing for me. All the technology it needs to fly is inside that thing while planes are incredible depended of their environment. The only thing that upsets me is that a rocket is just another device that heats up our atmoshere. we also don´t really know how our atmosphere really works in higher layers so we don´t know how much damage we are doing.
It´s still great to see this industry building up even though it just does for obvious economical reasons.
