SPACE SUCKS, FU SPACE PEOPLE
We believe delivering Nokia’s 4G/LTE system to the lunar surface is a transformative moment in the commercialization of space
Absolutely love the lack of regulation for space. Going to love seeing the Google tm Moon in 50 years.
Well, no regulation means we can be space pirates and fuuuuck Google up.
Yeah these companies think just because they can they should.
Fuck 'em. The moon is part of the view from my garden.
I’ll fight for that.
I dunno. What kind of service can you get with LowG™?
I know it kind of sounds silly, but this is some of the very first infrastructure on The Moon, and that’s pretty cool.
The Moon will likely be our main port for travel within our solar system - if we made a lunar space elevator we would use it as our launch point without having to expend so much fuel launching from Earth like we do with traditional rockets.
The moon rotates too slowly (about once every 30 days), you don’t want a space elevator for the moon, the tether would have to be ridiculously long.
But there’s no atmosphere, so you have another good option: a linear accelerator, or mass driver. Basically you make a very long, very straight rail and use electromagnetism to accelerate a craft right up to orbital velocity. The only complicated part is constructing 50 km of rail, but I mean, it’s more time consuming than complicated. This is actually way more feasible than a space elevator.
You still need to fire an engine on the far side of your orbit though which makes it more difficult as it still needs to be able to propel itself (while surviving the acceleration)
Well surviving the acceleration is trivial. I figured a 50km track in the post up above, in 50km you can accelerate up to lunar orbit velocities at just 1g of constant acceleration. So if your probe can survive sitting still on earth, it can survive accelerating at that speed.
You’re right though, you do need a small amount of thrust when you reach the top of your arc, but really not much. 50 m/s of DeltaV would do just fine. In other words, opening a can of compressed air would basically do it.
Or alternatively, you could use a mechanical system; you could have the vehicle (basically a rail cart) separate from the cargo with a powerful spring, pushing the cargo up, and the cart down. That mechanical system is also more effective the higher the apogee is, so if you launched the vehicle into a higher, more elliptical lunar orbit, that small push at the top pulls your low end of the orbit up much higher.
Ah, I was thinking more of a spinlaunch thing. Yours would make more sense, but would require a fuckton of industry in space or on the moon to have it work. I wonder how much more effective a self contained spinlaunch style thing would be on the moon.
Yeah, the application kind of assumes a lot of industry though. I mean if there isn’t a lot of industry, what are you shipping off the moon? But still, 50 km of rail is a lot, but it’s far less than the 325,000 km of tether that a space elevator would need…
Spin launch would definitely be feasible for some cargo, theoretically it would be a bit easier in vacuum, though that would probably also present other challenges. However, with a reasonably sized spin launch system (like the size of a 4 story apartment building), the payload needs to handle forces around 3000 Gs (which is a lot even for cargo). Unfortunately, you’d need to go larger for lower G force. So this also requires a lot of industry.
…but you have to get whatever it is you’re transporting to the moon first
As the saying goes, “orbit is halfway to anywhere.”
Getting into and out of gravity wells takes far more fuel than moving between planetary bodies. A space elevator that can take cargo from lunar orbit to the surface and back removes one difficulty, while being slightly less sci-fi-ish than a terrestrial elevator.
They addressed that in their post already.
We build the thing on the moon itself
Sure, it’s mostly barren rock, but it still got useful stuff there, like for example water (hydrogen and oxygen, rocket fuel), carbon and oxygen in the rocks (methane, also rocket fuel), metals (building rockets), and various other elements
From what I’ve read we know, it’s relatively poor in nitrogen and carbon, so the moon is not as useful as it could have been, but water is really all you need. If you can produce fuel and rocket parts on the moon, it’s about as useful as it can be for space exploration and development
Since, remember, the alternative is getting those resources either from the surface of the earth (expensive in terms of fuel, and requires powerful rockets, aka bigger ships, also expensive), or from some place further out like the asteroid belt (time consuming). Gravity on the moon is much much smaller, so even if we don’t have a space elevator, it would be far cheaper to use the moon as a starting point, or at least as a refueling point
A station and then a mine would imo make more sense for a first.
People really not feeling this in the current climate for sure
Nokia still exists?
yes
Yeah, Eriksson too. Both pretty much abandoned their consumer phone business. They have pivoted to afaik mostly telecommunications infrastructure. But both companies do a bunch of other stuff.
Nokia and Eriksson were really happy when Huawei started being kicked out of 5G infrastructure.
That’s not a bad bet. Clearly telecommunications infrastructure is not going away and even radio towers are never going away until physics finds an alternative.
I do kinda miss Nokia’s creativity tho
HMD are the the spun off Nokia mobile division. They just released a pretty fresh new android flagship.
Wow HMD’s stuff looks pretty slick!
Meshtastic on the moon… Moontastic!
