Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that the second generation ’V2-mini’ Starlink satellites emit up to 32 times brighter unintended radio waves than satellites from the previous generation, potentially blinding radio telescopes and crippling vital research of the Universe.

And consequently create radio chatter and disturb the Lunar Crater Telescope :(

I’ll be very quiet. Promise.

How are you going to shit post on the internet with no wifi, then? 2.4Ghz and 5Ghz are loud af

Where is that ethernet cable getting internet from on the moon without there being a loud as fuck antenna?

So then you won't be able to be quiet due to the screaming and moans coming from the cacaphony of lost souls within the Warp

[-] lath@lemmy.world 2 points 1 day ago

Eh, just treat it as ASMR.

Ethernet protocol can't reach the earth from the moon without there being a loud af antenna on either side

Fiber line to the bright side of the moon; transceiver there.

For multi-mode (full duplex) you would still need a power amp repeater every 500 meters, which requires a lot of power and create noise. You can't be quiet with noise.

Even if you make them sub-surface, or otherwise shield them from the FOV of the antenna?

[-] BaroqueInMind@lemmy.one 2 points 1 day ago* (last edited 1 day ago)

Yes, because there's no way to transmit power or data anywhere without being loud af in any signal spectrum. It's physically impossible.

Even with fiber, you need a laser to beam the signal, and a powerful amp on the moon to recieve the signal and boost it with fuck ton of high power repeaters to the other side of the moon which is also loud af

Be that as it may, it’d be minimal compared to the interference that terrestrial radio observatories have to deal with.

I guess I’m just saying that I don’t understand why you’re being so negative about the concept when it’s clearly going to be orders of magnitude better than existing antennae.

True. When can we visit said hypothetical moon base?

Wanna go next Tuesday? I’m pretty sure I’m free then.
