>An autonomous, robotic hydraulic excavator could build a dry stone wall to act as a blast shield around a launch pad on the moon, propose a team of Swiss researchers.
>The excavator would make use of in situ materials (rather than the costly practice of transporting building material from [~Earth~](https://www.space.com/54-earth-history-composition-and-atmosphere.html) to [~the moon~](https://www.space.com/55-earths-moon-formation-composition-and-orbit.html)), collecting rocks on the lunar surface for use in a ringed wall with a radius of between 50 and 100 meters (164 to 328 feet).
>”The robot would be used to both collect the boulders as well as to construct the wall,” study lead author Jonas Walther told Space.com.
Might be better to use an electric sled to get stuff into orbit there, it’s a mere 2.4km/s to hit escape velocity vs 11.9km/s on earth.
Or build a space elevator.
The largest rocket payload is about 150 metric tonnes. I work in construction. 1 rocket could carry everything needed to build any rocket pad you want. You could get aggregate from the moon. At a 3:1 ratio that means one rocket could supply 400 metric tonnes of concrete. You just need another rocket to bring machinery and steel reinforcement to build it. 2 rockets and you could have a fucking huge moon base with launch pad. Now we just need to know if concrete cures in space. I can write pointless paper and call myself a scientist too. Anyone wanna pay me to hypothesis bullshit ideas? Can we just fix the fucking climate now? Roofing in the summer is getting harder every year.
