@TechConnectify On the upside it’s easy to do CPU and GPU cooling.

@thomasfuchs I'll honestly bet that 90% of the people who claim to be gung-ho about the idea haven't thought about this.

@makdaam Hmm, you have a point

@thomasfuchs You're making the settling of Mars more and more attractive.
You're basically saying we could ship all of the Elonites to a place with latency larger than the TCP timeout and make them figure it out?

@gsuberland @TechConnectify “easy” as in probably comparatively not too hard to figure out a refrigerant when the hard part is the whole getting there

@thomasfuchs @TechConnectify seems like it'd be pretty tricky, tbh. if you wanted to exchange heat with the outside you'd need to work with the thin atmosphere, and it's not like you can just pump water or standard refrigerents when your external environmental temperature range is anything from -150C to +20C.
you could run the thing indoors like normal, but then you're adding extra artificial thermal load to the life support systems, which seems... not smart.

@gsuberland @TechConnectify and they can’t even browse Wikipedia to help find a solution 😂

@thomasfuchs @TechConnectify but still far, far harder than just running the computer on earth, which is sorta the problem with their outlook on space travel.

Fwiw, ping times of Earth to Mars communications are very roughly between 350,000ms to 750,000ms, depending on positions of planets in orbit; assuming there's enough bandwidth, which there won't be.
Even image attachments in emails that you get like batched once a day would likely be very expensive to send.

@thomasfuchs So the way to block ads and nazi memes on Xitter would be to move to Mars?

@Legit_Spaghetti can fix it with relays... that add even more latency :D

@thomasfuchs And in very rare circumstances, the Sun might block Earth/Mars transmissions.

@toba Maybe I miscalculated, I didn't have enough coffee yet perhaps.
(FWIW when they're at their farthest apart it's moot anyway because the sun blocks any communication.)

@thomasfuchs I thought it's worse than that.
> The two planets are farthest apart when they are both at their farthest from the sun, on opposite sides of the star. At this point, they can be 250 million miles (401 million km) apart.
At 186,000 miles/sec that's 1344 seconds one way

@Sci_Phi that would be slower than wireless (notwithstanding material science issues to make a 400 million km long cable)

@thomasfuchs what is it with people and wanting to go to Mars when we haven't set foot on the moon in decades, let alone thought about having people live there, even temporarily. Stop trying to make Mars happen people, it's not going to happen.

@TechConnectify @thomasfuchs maybe... Air is quite thin on mars, so you need a very fast air flow to cool electronics.
Or maybe a big surface to irradiate the heat?

@dan You can be surprsied or not, Mars has both extremely high ping times (tens of minutes) and extremely low throughput; e.g. the latest Mars rover (Perseverance) manages about 2 MBit/s, on a good day. On a bad day, it falls back to 800 bit/s X-band.

@thomasfuchs latency != throughput. I hear the ISS has a ~1s latency, but ~1Gbps throughput. I wouldn't be surprised if Mars has a similarly weird balance. An email attachment image might be barely a blip in the throughput, but I often think about what would need to go into building a usable "offline"/high latency internet. Email might be one of the easier bits, but what does web browsing even look like?

@dan I think you’re grossly underestimating the technical challenges involved.
The 2 MBit are to Mars orbit, not to Earth.
The direct link to Earth the rover has operates at 800 bits per second, and more importantly requires a 230-foot (70 meters) diameter receiving antenna dish on Earth.

@thomasfuchs I know the current comms infra isn't great, but I'd expect this to improve before humans get there, both for safety and maintaining human connection. Unless I'm mistaken there's nothing about Mars' remoteness that would prevent at least a throughput measured in Mbps most of the time, albeit with that high latency.
