The Quest to Build a Telescope on the Moon

Lunar Resources, a startup based in Houston, aims to construct the FarView radio telescope on the moon's far side, which would be the largest telescope in the solar system. This project not only seeks to advance astronomical research but also serves as a test for off-planet mining and manufacturing, known as in-situ resource utilization (I.S.R.U.). The telescope would consist of around 100,000 antennas made on-site by autonomous robots, covering an area equivalent to Baltimore. It aims to detect radio waves from the Cosmic Dark Ages, a period shortly after the universe's formation. The project, which could take over a decade and cost upwards of $2 billion, is part of a broader vision for lunar infrastructure that could support future space exploration and economic activities. Lunar Resources has partnered with various scientists and universities to develop the telescope's design and has received funding from NASA. The success of FarView could pave the way for lunar mining operations, potentially extracting resources like helium for fusion reactors and water for rocket fuel. The initiative reflects a growing interest in utilizing the moon's resources to support human activities in space, with projections suggesting a lunar economy could be worth $170 billion by 2040.

I'm pretty skeptical, as a general rule if something has never been done on earth before you're not going to do it in space. Not that I think this is impossible, but nobody even has autonomous mining and construction abilities on earth, and they're going to do that on the moon with an extremely limited ability to perform manual maintenance (I'm sure they have some sort of remote manually-operated drone in mind but again, nobody's ever even done that on earth and they're going to do it in space).

TFA also left out that it's not only going to be a PoC for autonomous mining and manufacturing, but also autonomous refining. When the Toyota corporation built my car they didn't start with unrefined steel ore. I don't even know how they're going to do that in a vacuum where there's no fires and no convection.

There was an interesting Fraser Cain YT vid a couple of weeks back:

Interview with Gerard van Belle, director or the Lowell Observatory.

The topic was space/lunar optical interferometers. It's easier to do this on the Moon than in space, as there's no formation flying. He's got a "menu" of projects from a few/small unit telescopes right up to lunar manufacturing like this.

The JPL position is that telescopes should be in space, not on Luna. Too much dust. Too much gravity. A lunar farside optical telescope was proposed, but it would be inferior to one in open space.

It's just so simple and clean though, if we can't do something this basic yet so useful, we should just stop all the space stuff and go back to bombing each other to death until the planet completely melts and floods in 50 years because we're done. Type-Zero civilization.

That would be great if that can happen, plus I hope the can build a Radio Telescope on the Moon with it.

That should avoid all the Radio Interference that plagues Earth Based Radio Telescopes.

I don't know about radio telescopes but it does sound like a good platform, no atmosphere, no magnetosphere, etc. Is it just me or does this sounds like a more viable goal for the next 20 years, than Mars.

Let's say this works, and they paint a lot of metal lines that form workable antennas on the moon surface.

How do you aim that thing at a specific point in the sky?

The SpaceX 'Starship Human Landing System' is supposed to land on the moon in 2025 or so and should have a cargo variant able to deliver quite a few tons of gear. It would interesting to send some prototype telescope stuff. (https://en.wikipedia.org/wiki/Starship_HLS)

> Lunar ice could provide hydrogen and oxygen for rocket fuel, which could power trips to deep space.

Stop. Right. There. Time to read A City on Mars: https://www.acityonmars.com/

This is quickly turning into a pipe dream. Someone is letting their imagination run away.

There simply isn't enough water on the moon to make hydrogen / oxygen for deep space travel.

Why would a moon telescope be desirable over a satellite telescope?

Ah yes, the 'ole investor pump and dump. Get a bunch of people excited enough to give you millions, make enough to retire and then just disappear in a whiff.
